Is It Time to Replace Your Consumer Unit?

Your consumer unit distributes electricity around your home and contains the protective devices for your electrical circuits.

A replacement may be appropriate if:

  • Your existing fuse box has no RCD protection.
  • Your existing fuse box is damaged, deteriorated or unsuitable for continued use.
  • An electrical inspection identifies issues requiring an upgrade.
  • You are extending, renovating or making significant electrical alterations.
  • You need additional capacity for new circuits or equipment.


An older fuse box does not automatically mean your home needs rewiring or that the unit must be replaced. We can assess its condition, the existing circuits and your requirements before recommending the appropriate work.


Modern RCBO Circuit Protection

We install modern consumer units with individual RCBO protection as a standard.


An RCBO combines protection against overloads and short circuits with residual-current protection, helping reduce the risks associated with certain electrical faults.


With individual RCBOs, a fault on one circuit will normally disconnect that circuit rather than several circuits sharing one RCD. 

This can help minimise disruption and make faults easier to identify.


We select suitable protective devices for your installation and explain how to operate them during handover.

Surge Protection Device

A surge protection device, or SPD, helps protect electrical equipment against transient overvoltages — brief increases in voltage that can damage sensitive electronics.


We include surge protection in our proposed consumer unit specification and explain its role alongside the other protective devices.


An SPD complements circuit protection; it does not replace protection against electric shock, overloads or short circuits.
