What is a consumer unit?
The consumer unit, often called the fuse board, is where your electricity supply is split into circuits. Modern units use RCDs and RCBOs that cut the power in milliseconds if there is an earth fault, giving far better protection against shock and fire than old fuses.

Tested before we start
Modern protective devices are more sensitive than old fuses, so hidden faults can show up after an upgrade. We test your existing circuits first, so you know about any issues before the day.

Get a free quoteHow long does a consumer unit upgrade take?
Usually one day, with the power off for part of it.
Why might a consumer unit change find other faults?
Modern protective devices are more sensitive. Existing faults that old fuses ignored can show up, and we test circuits first so there are no surprises.
Do I need a new consumer unit for solar or an EV charger?
Not always, but many older units do not have the space or protection required. We check at survey.
