Consumer unit replacement

Replacing your consumer unit — a new board, tested and certified

A board with rewireable fuses, no surge protection or a single RCD (residual current device) for the whole house is the most common reason to replace it. A new consumer unit gets separate circuits, surge protection and space for whatever you add later.

Sound familiar?

  • A single RCD trips the whole house when one appliance develops a fault.
  • No surge protection — after a thunderstorm, electronic equipment fails.
  • Too few circuits: induction hob, washing machine and dryer on one breaker.
  • No space for solar PV, an EV charger or a heat pump.

What's in this consumer unit

  • Main switch and surge protection device (SPD; Type 1+2 in versions M, L and XL).
  • 4-pole RCDs — a separate one for each group of circuits.
  • An MCB (miniature circuit breaker) for every circuit, phase indicators, N/PE terminal bars, circuit chart.
  • Installation with removal of the old board, protective testing and a test report.

Frequently asked questions

How long does a consumer unit replacement take?

Installation at your home usually takes 4–8 hours, with the power off while we work. The consumer unit is built in our workshop beforehand (5–10 working days from the deposit).

Do I need to notify the network operator?

Replacing the consumer unit after the meter does not need to be notified. If you are moving the meter or changing your supply capacity, it does — and we will prepare a meter board to the network operator’s requirements.

What about circuits that cannot be split?

We reuse the existing cables. The number of circuits in the new consumer unit matches what is in your walls, plus spare capacity for the future.
