The consumer unit is the heart of your electrics. Older fuse boxes offer little protection against electric shock or fire. A modern unit with RCDs or RCBOs will cut the power in a fraction of a second if something goes wrong.

When to upgrade

• Your fuse box has rewirable fuses or no RCD protection
• You have a plastic consumer unit in a hallway or under the stairs (current regulations require a metal enclosure for new installs)
• You are adding a big load – EV charger, electric shower, hot tub, extension
• An EICR has recommended it
• It trips regularly and nobody can tell you why

What we do

We inspect and test the existing circuits first, because a new unit will pick up faults an old fuse box ignored. We then fit the new unit, label every circuit clearly, test everything and issue an Electrical Installation Certificate. Most changes are completed in a day, with the power off for around 4–6 hours.

RCD vs RCBO – what is the difference?

An RCD protects a group of circuits; if one faults, several trip. An RCBO protects each circuit individually so a fault in the kitchen does not turn the lights off upstairs. We will explain both and quote what suits your home and budget.

Common questions

Will it find problems in my wiring?
Sometimes, yes – that is the point. We test before we fit so we can tell you up front if anything needs fixing rather than surprising you afterwards.
