Our Terms of Service
GENERAL TERMS OF SERVICE
Applies to all Oxford Installations Ltd services
These General Terms should be read with the accepted quotation and the relevant service-specific terms. They replace the general commercial provisions in the company's previous Terms of Service.
1. Definitions and contract documents
In these terms, “we”, “us” and “our” mean Oxford Installations Ltd. “Customer”, “you” and “your” mean the person or organisation named on the quotation. “Works” means the services, labour, goods and materials described in the accepted quotation.
The contract consists of the accepted quotation, these General Terms, the applicable service-specific terms, any drawings/specification expressly incorporated, and any agreed written variations. If documents conflict, a specifically agreed quotation or variation takes priority over a general term, except where the law or an applicable consumer-protection scheme requires otherwise.
2. Quotations and acceptance
Unless stated otherwise, quotations are valid for 30 days. A quotation is based on the information and site conditions reasonably available when it is prepared.
A contract is formed when you accept our quotation or otherwise instruct us to proceed and we accept that instruction. Acceptance may be electronic, written, or through our quotation/job-management system.
Anything not expressly included in the quotation is excluded. We may correct an obvious clerical or pricing error before acceptance.
3. Working hours, attendance and access
Our normal working hours are 8:00am to 5:00pm Monday to Friday unless otherwise agreed.
You must provide safe and reasonable access at the agreed time and keep work areas reasonably clear. If our operative cannot gain access at a confirmed appointment through no fault of ours, a £90 + VAT failed-access charge may apply. If scheduled work cannot reasonably proceed because of obstructions, accessibility or site readiness, a £60 + VAT standing/aborted-work charge may apply where this was made clear before attendance.
Parking, congestion, clean-air/low-emission and similar site-specific charges reasonably incurred in carrying out the Works may be passed on where stated in the quotation or notified before they are incurred.
4. Customer responsibilities
You must provide accurate information relevant to the Works and tell us about known hazards or restrictions before work starts.
- Known or suspected asbestos and, for non-domestic premises where applicable, access to the asbestos register.
- Known concealed electrical, gas, water, drainage, data, telephone or other services.
- Known structural defects, leaks, fragile finishes or other conditions likely to affect the Works.
- Any landlord, freeholder, planning, listed-building, lease, management-company or other third-party permission for which you are responsible.
- Reasonable access to electricity, water and toilet/welfare facilities where required.
5. Existing installations and unforeseen conditions
Our price assumes existing installations and the building are reasonably suitable for the proposed Works unless the quotation says otherwise. Opening up, testing or commissioning may reveal defects or conditions that could not reasonably have been identified beforehand.
If additional work is reasonably necessary for safety, compliance or completion, we will explain the issue and, where practicable, agree the additional price before proceeding. We may suspend work where continuing would be unsafe or unlawful.
6. Variations and additional work
Changes requested after acceptance may affect price and programme. Wherever reasonably practicable, variations will be agreed before the additional work is carried out.
Additional charges may include labour, materials, redesign, specialist access, restocking/cancellation costs, return visits and other reasonable costs caused by the change. Emergency action reasonably necessary to remove an immediate danger or prevent material damage may be taken where prior approval cannot reasonably be obtained.
7. Materials, substitutions and customer-supplied goods
Materials supplied by us will be suitable for the contracted purpose and new unless otherwise agreed. If a specified item becomes unavailable, we will discuss a suitable alternative before making a material substitution.
If we agree to install Customer-supplied equipment, we are responsible for our installation work but not for defects inherent in the equipment. Additional labour to diagnose, remove or replace defective Customer-supplied equipment may be chargeable. We may refuse equipment we reasonably consider unsafe, unsuitable, incompatible, damaged or non-compliant.
8. Flooring, chasing, making good and cleanliness
Where floor coverings need lifting for concealed installation work, we will use reasonable care, but specialist reinstatement is excluded unless stated. Where agreed, wall chases may be filled to approximately 2mm below finished plaster level; skim plastering and final decoration are excluded unless specifically included.
Cables, pipes, trunking or other services will be concealed where reasonably practicable and included in the quotation; otherwise surface routes may be necessary. We will use reasonable care to keep the work area clean.
9. Price and VAT
Prices are inclusive or exclusive of VAT as stated on the quotation. VAT is charged at the rate required by law.
A fixed quotation may be adjusted only where the scope changes, information supplied was inaccurate/incomplete, unforeseen conditions arise, third-party requirements change, or another contractual basis for a variation applies.
10. Deposits and stage payments
Where a deposit is required, the amount and due date will be stated on the quotation. Unless a different schedule is agreed, domestic projects over £1000 may require a 25% deposit and commercial/contractor projects over £1,500 may require a 25% deposit.
For larger projects we may use stage payments linked to agreed milestones. Renewable-energy consumer projects are also subject to the deposit and advance-payment protections stated in the Solar PV & Battery Storage Terms and applicable consumer-code requirements.
11. Invoices and Payment
Unless the quotation states otherwise, payment terms are as follows:
- Domestic invoices below £1,000 including VAT: Payment must be made in full within 24 hours of the invoice date.
- Domestic invoices of £1,000 or more including VAT: Payment must be made in full within 7 calendar days of the invoice date.
- Commercial and contractor invoices: Payment must be made in full within 30 calendar days of the invoice date, unless the quotation or an agreed stage-payment schedule states otherwise.
Commercial or contractor projects may be subject to deposits, interim payments, stage payments or other payment arrangements as stated in the quotation.
Where only part of an invoice is genuinely disputed, the customer must pay the undisputed amount by the applicable payment due date. The customer must not withhold an amount substantially greater than the reasonable value of the genuinely disputed item.
We reserve the right to suspend further works or services where an undisputed payment remains overdue, after giving reasonable notice and where permitted by the contract and applicable law.
Nothing in this section limits either party's statutory rights or remedies.
12. Late Payment and Debt Recovery
Payment & Late Payment – Domestic Customers
Once the applicable payment period set out in Section 11 has expired, any unpaid and undisputed amount will be considered overdue.
Where an invoice becomes overdue, Oxford Installations Ltd reserves the right to charge interest on the outstanding balance at a rate of 4% per annum above the Bank of England base rate, calculated daily from the date the payment became overdue until payment is received in full.
Oxford Installations Ltd may issue payment reminders and formal demands for payment and may suspend or decline to undertake further non-essential works while an undisputed amount remains overdue, where it is lawful and reasonable to do so.
Where payment remains outstanding following reasonable requests for payment, Oxford Installations Ltd reserves the right to refer the debt to a debt recovery agency or solicitor and/or commence court proceedings where appropriate.
Where Oxford Installations Ltd incurs reasonable and necessary costs directly as a result of recovering an overdue debt, we reserve the right to seek recovery of those costs where permitted by law.
Payment of the original invoice after it has become overdue does not automatically waive any interest or other amounts that have lawfully become due.
Any interest or recovery costs applied will be fair and proportionate and will not exceed amounts Oxford Installations Ltd is legally entitled to recover.
Nothing in these terms affects the customer's statutory rights.
12.2 Late Payment – Commercial Customers
Any undisputed commercial or contractor invoice not paid within the applicable payment period set out in Section 11 will be considered overdue.
Where a qualifying commercial invoice becomes overdue, Oxford Installations Ltd reserves the right to exercise its full statutory entitlement under the Late Payment of Commercial Debts (Interest) Act 1998 and associated legislation.
This includes:
- Statutory interest at 8% per annum above the applicable Bank of England reference rate, accruing from the date the payment becomes overdue until payment is received in full.
- £40 statutory compensation for a qualifying debt of up to £999.99.
- £70 statutory compensation for a qualifying debt of £1,000 to £9,999.99.
- £100 statutory compensation for a qualifying debt of £10,000 or more.
- Additional reasonable debt-recovery costs where the reasonable costs incurred in recovering the overdue debt exceed the applicable statutory fixed compensation.
These rights may be exercised without Oxford Installations Ltd being required to provide any further extension to the agreed payment period.
Where an undisputed account remains overdue, Oxford Installations Ltd reserves the right, where permitted by the contract and applicable law, to suspend further works or services until all outstanding amounts have been paid.
Continued non-payment may result in the account being referred to a debt recovery agency or solicitor and/or court proceedings being commenced without any further extension of the agreed payment period.
The customer will remain liable for the outstanding principal together with any statutory interest, statutory compensation and additional reasonable recovery costs that Oxford Installations Ltd is legally entitled to recover.
Payment of the original invoice after it has become overdue does not, by itself, waive Oxford Installations Ltd's right to recover any statutory interest, compensation or qualifying recovery costs that have become due.
13. Consumer Cancellation Rights and Early Commencement
13.1 Where required by law, a consumer Customer has a 14-day statutory cancellation period.
13.2 The Customer does not have to wait 14 days for the Works to commence. If the Customer wishes Oxford Installations Ltd to begin the Works before the end of the cancellation period, the Customer may expressly request that we start early.
13.3 By requesting an early start, the Customer authorises Oxford Installations Ltd to commence the services and to order, obtain and/or supply the materials reasonably required to carry out the agreed Works.
13.4 If the Customer subsequently cancels the contract during the cancellation period after requesting an early start, the Customer may be required, to the extent permitted by law, to pay for services already supplied and for goods or materials for which the Customer is legally responsible as a result of the cancellation.
13.5 Where goods remain subject to a statutory right of cancellation, those goods will be dealt with in accordance with the Customer's statutory rights. Nothing in these Terms makes standard materials automatically non-refundable merely because Oxford Installations Ltd has ordered them.
13.6 Where the contracted service has been fully performed during the cancellation period following the Customer's express request to start early and the acknowledgements required by law have been obtained, the Customer's statutory right to cancel that service may end.
13.7 For off-premises contracts, any request to commence services during the cancellation period will be obtained in the form required by law.
13.8 Solar PV and Battery Storage contracts may be subject to additional cancellation, early-installation, deposit and consumer-protection requirements under the Renewable Energy Consumer Code (RECC). Where applicable, those requirements will also apply.
13.9 Nothing in this section affects the Customer's statutory rights.
14. Cancellation outside a statutory cooling-off period
If you cancel after any statutory or contractual cooling-off period, we may recover reasonable losses caused by the cancellation, including work already carried out, specially ordered or non-returnable goods, and reasonable supplier/restocking charges, to the extent permitted by law. We will take reasonable steps to mitigate avoidable loss.
We do not rely on a blanket percentage cancellation charge where it would exceed our reasonable loss.
15. Programme and delays
Dates are given in good faith. Unless expressly guaranteed in writing, they are estimates. We are not responsible for delay caused by events outside our reasonable control, including severe weather, supplier shortages, DNO/utility delays, approvals, access restrictions, illness/emergency, unsafe conditions or delays by other contractors. We will keep you reasonably informed of material delays.
16. Risk and title to goods
Risk in goods passes as provided by law and the circumstances of delivery/installation. Title to goods supplied by us remains with Oxford Installations Ltd until sums properly due for those goods under the contract have been paid in full, so far as such retention is legally effective.
You should maintain appropriate buildings/contents/site insurance during the Works.
17. Testing, certification and documents
Where applicable, we will inspect, test and commission the Works and provide the certificates/documents required for the contracted scope. A certificate relates only to the installation or extent described on it and is not a guarantee that unrelated existing installations are defect-free.
Duplicate copies of archived electrical certificates may be provided, where available, for an administration charge of £60 + VAT.
18. Workmanship and manufacturer warranties
Our workmanship warranty is the period stated in the quotation, service-specific terms or applicable scheme requirements. If no longer period is stated, our standard workmanship warranty is 12 months for non-RECC work.
Manufacturer warranties are separate and subject to the manufacturer's conditions. Where a product fails under a manufacturer warranty but the failure is not caused by our workmanship, reasonable labour for diagnosis, removal or replacement may be chargeable if the manufacturer's warranty does not cover labour.
Warranty does not normally cover misuse, accidental damage, neglect, lack of required maintenance, third-party alteration, external supply/network failures, pest damage, vandalism or defects in Customer-supplied equipment. Nothing here limits statutory rights.
19. Faults, complaints and opportunity to inspect
Please notify us promptly of a suspected defect and give us a reasonable opportunity to inspect and, where we are responsible, remedy it. If investigation shows the reported fault is unrelated to our Works, a reasonable attendance/diagnostic charge may apply if notified in advance.
Complaints should first be raised with Oxford Installations Ltd. Where applicable, complaints may also be handled under relevant NAPIT, MCS, RECC or other scheme procedures and available alternative dispute resolution arrangements.
20. Liability
We are responsible for loss or damage that is a foreseeable result of our breach of contract or failure to use reasonable care and skill. We are not responsible for pre-existing defects or for loss caused solely by matters outside our reasonable control.
Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any consumer right or other liability that cannot lawfully be excluded or restricted.
21. Photographs, records and data
We may take photographs and retain technical records for installation, certification, warranty, compliance and quality-control purposes. Personal data will be handled in accordance with our applicable privacy information. We will obtain appropriate permission before using identifiable customer/property imagery for marketing where required.
22. Governing law
These terms are governed by the law of England and Wales. Consumers retain any mandatory rights concerning jurisdiction that apply to them.
Acceptance
By accepting the quotation or otherwise instructing Oxford Installations Ltd to proceed, the Customer confirms that they have received or been given access to the General Terms and Conditions and these General Terms & Conditions, and agrees that they form part of the contract.
Important: Nothing in these terms excludes or restricts rights or remedies that cannot lawfully be excluded or restricted.
ELECTRICAL SERVICES TERMS
Electrical installations, alterations, testing and associated services
These terms supplement the Oxford Installations Ltd General Terms & Conditions and apply to electrical work.
1. Scope
These terms cover domestic and commercial electrical installation work, new builds and rewires, alterations and additions, consumer units/distribution equipment, lighting, EICRs, fault finding, repairs, security/data cabling and related electrical services where stated in the quotation.
2. Standards and compliance
Electrical installation work will be carried out to the applicable requirements in force for the contracted work, including BS 7671 and relevant Building Regulations requirements where applicable. We will not knowingly carry out a Customer-requested deviation that would make the installation unsafe or unlawful.
3. Existing installations
Where we extend or modify existing circuits, the quotation assumes the relevant existing installation is suitable for connection. Testing may reveal inadequate earthing/bonding, insulation resistance faults, polarity issues, damaged accessories/cables, unsuitable protective devices or other defects. Necessary remedial work is additional unless included in the quotation.
4. Consumer-unit and distribution-board work
A replacement consumer-unit/distribution-board quotation assumes existing circuits can be safely reconnected. Mandatory testing may expose pre-existing faults. We will explain material defects and any additional work required before proceeding where reasonably practicable.
5. EICRs
An Electrical Installation Condition Report records the condition of the installation, subject to the extent and agreed limitations of the inspection, at the time it is carried out. It is not a guarantee that no fault exists or will later develop. Remedial work identified by the report is excluded unless separately quoted.
6. Cable routes and finishes
Cable routes will follow the agreed proposal where reasonably practicable. Hidden obstructions may require reasonable route changes. Chasing, lifting/refitting flooring and making good are governed by the General Terms and the quotation. Final plaster skim, decoration, specialist flooring and joinery are excluded unless expressly included.
7. Isolation and interruption
Electrical work may require temporary isolation of all or part of the supply. The Customer is responsible for protecting sensitive equipment and making arrangements for systems that must remain continuously powered unless we have expressly agreed to provide temporary supplies.
8. Testing and certification
Depending on the work, documentation may include an Electrical Installation Certificate, Minor Electrical Installation Works Certificate, Electrical Installation Condition Report and/or Building Regulations notification/certificate. Documentation applies to the scope stated on it.
9. Customer-specified equipment
If the Customer specifies a particular accessory, luminaire, control or other product, its performance and compatibility remain subject to the manufacturer's specification. Where Customer-supplied equipment is installed, the General Terms on Customer-supplied goods apply.
10. Fault finding and repairs
Fault-finding charges cover the agreed diagnostic attendance/time and do not guarantee that every fault can be identified or permanently repaired within that period. We will seek approval before carrying out material additional remedial work.
11. Warranty
Our standard non-scheme electrical workmanship warranty is 12 months unless the quotation states a longer period. Statutory rights remain unaffected.
Acceptance
By accepting the quotation or otherwise instructing Oxford Installations Ltd to proceed, the Customer confirms that they have received or been given access to the General Terms and Conditions and these Electrical Services Terms, and agrees that they form part of the contract.
Important: Nothing in these terms excludes or restricts rights or remedies that cannot lawfully be excluded or restricted.
SOLAR PV & BATTERY STORAGE TERMS
Domestic and commercial solar PV, battery storage and associated works
These terms supplement the General Terms. For qualifying domestic renewable-energy contracts, applicable MCS and RECC requirements also form an important consumer-protection framework and take precedence where they provide greater protection.
1. Design basis
The proposed system is designed from the survey information, roof/site dimensions, shading assumptions, electricity use information supplied by the Customer and equipment data available at the time. Final design remains subject to technical survey, structural/site suitability, electrical supply, DNO requirements and equipment availability.
2. Performance estimates
Generation, savings, self-consumption, battery utilisation, export income and payback figures are estimates, not guarantees, unless expressly stated otherwise. Actual results depend on weather, shading, orientation, household/business consumption, tariffs, export arrangements, equipment behaviour, degradation and grid restrictions. Formal performance estimates will be produced as required for the applicable scheme/scope.
3. Technical survey and variations
If survey or design work identifies a material change to system size, equipment, price, expected performance or installation method, we will explain the proposed change and obtain agreement in accordance with applicable contract and consumer-code requirements before proceeding.
4. Roof and structure
Unless expressly included, our survey is not a full structural or roofing-condition survey. The Customer must disclose known roof defects. If the roof or supporting structure appears unsuitable, we may pause work pending repair or specialist assessment. We are not responsible for pre-existing roof defects.
5. Scaffolding and access
Scaffolding, lifting equipment and specialist access are included only where stated. If previously unknown site conditions require additional access measures for safe working, these will be treated as a proposed variation.
6. DNO and grid connection
The installation may require DNO notification or prior approval, including the applicable G98/G99 process or other network requirements. Where we handle the application, we cannot control the DNO's processing time, decision, export limit or requirement for network/supply upgrades. Third-party charges are excluded unless stated.
7. MCS and handover documentation
Where the installation falls within our MCS-certified scope and meets the applicable requirements, we will complete the required MCS process and provide/arrange the relevant handover documentation. The Customer must retain certificates, warranties, commissioning records and insurance-backed protection documents.
8. Deposits, advance payments and workmanship protection
For qualifying RECC consumer contracts, deposits and further advance/stage payments will be protected as required by the applicable RECC rules, and the workmanship warranty will be protected through an eligible insurance-backed or equivalent arrangement. The specific provider, scope, period and policy terms will be supplied for the project.
9. Cancellation
Qualifying consumers have the cancellation rights stated in the General Terms and any additional rights required by RECC. Any early-start request, cancellation form and treatment of goods/services supplied during the cancellation period will be handled under the applicable legal and scheme requirements.
10. Battery storage and backup
Quoted battery capacity and usable capacity are subject to manufacturer specifications. A battery does not automatically provide backup during a grid outage. EPS/backup capability is included only if expressly stated, and may supply only selected circuits or a limited output. Runtime depends on battery state of charge and connected loads.
11. Inverters, optimisers and system limitations
Inverter clipping, export limitation, battery reserve settings, thermal derating and other manufacturer/control behaviours can occur during normal operation and are not necessarily faults. System output is limited by the design, equipment ratings, DNO constraints and prevailing conditions.
12. Monitoring and communications
Online monitoring may rely on the Customer's broadband/Wi-Fi/mobile connection and manufacturer cloud services. Loss of connectivity does not necessarily mean the generating/storage equipment has stopped operating. Third-party platform availability is outside our control.
13. Export tariffs and energy suppliers
Unless expressly included, the Customer is responsible for applying to their electricity supplier for any Smart Export Guarantee or other export tariff. We do not guarantee eligibility, tariff level, supplier acceptance or future financial return.
14. Manufacturer warranties and servicing
Panels, inverters, batteries, optimisers and other equipment may have different warranty periods and conditions. Registration, internet connectivity, maintenance or operating conditions may affect manufacturer cover. Our workmanship obligations are separate from manufacturer product warranties.
15. Ownership and access to data
Manufacturer monitoring portals may process system and usage data under their own terms/privacy notices. The Customer is responsible for maintaining their account credentials and notifying us of ownership changes where platform transfer is required.
Acceptance
By accepting the quotation or otherwise instructing Oxford Installations Ltd to proceed, the Customer confirms that they have received or been given access to the General Terms and Conditions and these Solar PV & Battery Storage Terms, and agrees that they form part of the contract.
Important: Nothing in these terms excludes or restricts rights or remedies that cannot lawfully be excluded or restricted.
EV CHARGING TERMS
Electric vehicle chargepoint installation and associated electrical works
These terms supplement the General Terms and apply to domestic and commercial EV chargepoint installations.
1. Survey and design basis
The quotation is based on the known incoming supply, earthing arrangement, consumer unit/distribution board, proposed charger position, cable route, maximum demand and communications available at survey. Hidden conditions or inaccurate information may require a variation.
2. Existing electrical installation
The existing installation must be suitable for the charger connection. Additional earthing/bonding, protective devices, consumer-unit work, surge protection, supply alterations or remedial work is excluded unless stated.
3. DNO and supply capacity
EV installations may require DNO notification or approval. We cannot control DNO response times, network decisions or the need for a service/supply upgrade. Any DNO or utility charge is excluded unless specifically included.
4. Charging rate
A charger's advertised maximum output does not guarantee the vehicle will charge at that rate. Actual charging may be limited by the vehicle's onboard charger, property supply capacity, load management, battery temperature/state, charger settings, tariffs or DNO restrictions.
5. Dynamic load management
Where load management is fitted, charger output may automatically reduce or pause when property demand rises. This is intended system behaviour and is not, by itself, a fault.
6. Smart functions, apps and tariffs
App control, scheduled charging, solar integration, tariff integration and remote monitoring can depend on Wi-Fi/mobile coverage, manufacturer servers, energy-supplier systems and third-party software. We are not responsible for outages or later changes to third-party services that are outside our control.
7. Customer accounts and connectivity
The Customer is responsible for maintaining compatible internet/network access, app accounts, passwords and subscriptions unless the quotation states otherwise. We will provide reasonable commissioning assistance for the installed product.
8. OZEV and grant-funded work
Where a grant scheme applies, eligibility is governed by the scheme rules in force at the relevant time. We cannot guarantee grant approval. The Customer must provide accurate information and evidence and comply with eligibility conditions. Any grant value or process will be shown separately where applicable.
9. Groundworks and civil works
Trenching, ducting, excavation, core drilling beyond the quoted scope, bollards, barriers, line marking and reinstatement are excluded unless expressly included.
10. Testing and certification
The charger circuit will be tested and appropriate electrical documentation provided for the contracted scope. Required DNO/OZEV records will be handled where included and applicable.
11. Warranty
Our workmanship warranty is as stated in the General Terms/quotation. The charger manufacturer's product warranty is separate and subject to its own conditions. Labour for replacement of a manufacturer-failed product may be chargeable where not covered by the manufacturer and the failure is not caused by our workmanship.
Acceptance
By accepting the quotation or otherwise instructing Oxford Installations Ltd to proceed, the Customer confirms that they have received or been given access to the General Terms and Conditions and these EV Charging Terms, and agrees that they form part of the contract.
Important: Nothing in these terms excludes or restricts rights or remedies that cannot lawfully be excluded or restricted.
AIR CONDITIONING TERMS
Domestic split and multi-split air-conditioning installation
These terms supplement the General Terms and apply to air-conditioning and heat-pump comfort cooling/heating systems installed or serviced by Oxford Installations Ltd.
1. System selection and sizing
Equipment is selected using the survey information available, including room dimensions, glazing, orientation/solar gain, insulation, occupancy and significant internal heat gains. Performance varies with building fabric, external temperature, doors/windows, occupancy and use. A stated equipment capacity is not a guarantee of a particular room temperature in every condition.
2. Indoor-unit position
Indoor-unit positions are subject to suitable wall/ceiling construction, manufacturer clearances, airflow, pipe route, condensate route and service access. Minor position changes may be necessary when hidden conditions become apparent.
3. Outdoor-unit position
Outdoor units require suitable support, ventilation, drainage, clearances, pipe/cable routes and future service access. The Customer must not later obstruct required airflow or access.
4. Pipework and trunking
Refrigerant pipework, interconnections and decorative trunking will follow the quoted route where reasonably practicable. Hidden obstructions may require a reasonable route change. Colour/size of trunking and external supports will be as stated or agreed.
5. Condensate drainage
Air-conditioning systems produce condensate in normal operation. Gravity drainage will be used where reasonably practicable. Where it is not, a condensate pump may be required. Pumps contain moving parts, may make audible noise, require cleaning/maintenance and can eventually need replacement.
6. Refrigerant pipe lengths
Installation is subject to the selected manufacturer's minimum/maximum pipe lengths, vertical separation and additional refrigerant requirements. If the final route materially exceeds the surveyed allowance, additional materials/refrigerant/labour may be chargeable by agreement.
7. Electrical supply
The electrical supply arrangement is as stated in the quotation. Additional consumer-unit/distribution-board work, remedial electrical work or supply upgrades are excluded unless specifically included.
8. F-Gas and refrigerant work
Where regulated fluorinated refrigerants are involved, installation, leak-related work, servicing, recovery and decommissioning within our scope will be carried out using appropriately certified personnel/company arrangements as required by applicable law.
9. Pressure testing, evacuation and commissioning
New refrigerant circuits will be installed and commissioned using the procedures appropriate to the equipment and installation, which may include pressure testing, evacuation, leak checks, electrical tests and operational checks. Commissioning records will be provided where required.
10. Heating and defrost operation
Heat-pump heating output and efficiency vary with outdoor conditions. During cold-weather operation the outdoor unit may enter a defrost cycle; heating can temporarily reduce or pause and water/steam may be visible at the outdoor unit. This is normal operation.
11. Multi-split systems
Where multiple indoor units share one outdoor unit, available capacity is shared and operation is subject to the selected system's limitations. If the manufacturer does not permit simultaneous heating and cooling, connected indoor units must operate in compatible modes.
12. Noise and vibration
Indoor units, outdoor units and condensate pumps produce operational sound and vibration within their design characteristics. We will use appropriate mounting methods, but absolute silence cannot be guaranteed. Noise experienced at neighbouring property can also depend on siting, structures and ambient conditions.
13. Wi-Fi and apps
Manufacturer Wi-Fi/app functions depend on compatible Customer networks, internet access and third-party cloud services. We cannot guarantee continuous availability of manufacturer apps or servers.
14. Maintenance and filters
The Customer is responsible for routine filter cleaning and for arranging servicing at intervals required by the manufacturer or warranty. Lack of maintenance can reduce performance, increase energy use, cause drainage/air-quality issues and affect warranty cover. A maintenance plan is included only if expressly stated.
15. Manufacturer warranty
Manufacturer warranty periods and conditions vary by product and may require registration and documented servicing. Our workmanship warranty is separate. Where a manufacturer product fails but our workmanship is not at fault, labour may be chargeable if not covered by the manufacturer.
16. Planning and third-party permissions
The Customer is responsible for obtaining planning, landlord/freeholder or other permissions unless the quotation expressly states that we will do so. External-unit siting may be subject to planning or property restrictions.
Acceptance
By accepting the quotation or otherwise instructing Oxford Installations Ltd to proceed, the Customer confirms that they have received or been given access to the General Terms and Conditions and these Air Conditioning Terms, and agrees that they form part of the contract.
Important: Nothing in these terms excludes or restricts rights or remedies that cannot lawfully be excluded or restricted.
