Consumer Unit Upgrade in Stockport: Do You Actually Need One?

We come across a lot of original fuse boards on our Stockport jobs, particularly in the older terraces around Edgeley and Heaton Norris that haven't had electrical work done since they were built or last rewired decades ago. Most people don't think about their consumer unit until something trips, or until an EICR flags it, or until an insurer asks a question they can't answer.

The tell-tale signs

If your fuse board is a wooden or plastic box rather than metal, that's your first clue it's old — current regulations require metal enclosures. A mix of round pin and rectangular switches, no visible test button, or rewireable fuses with actual fuse wire instead of switches are all signs it predates modern RCD protection entirely. If you genuinely don't know when it was last replaced, it's worth getting checked rather than assuming.

Why it actually matters

This isn't just a box-ticking exercise. A modern consumer unit with RCD protection cuts power in milliseconds if it detects a fault to earth, which is the difference between a nasty shock and a fatal one in some situations. Old fuse boards without that protection are still legal to leave in place, but they're one of the most common things that turn a C3 recommendation into a C2 defect on an EICR.

What the upgrade involves

Most domestic upgrades are done in a single day, including testing and certification. You'll be without power for part of that day while the old board comes out and the new one goes in — we'll tell you exactly when to expect the power to be off so you can plan around it. We fit metal enclosures with RCD or RCBO protection as standard, and split-load boards where it makes sense so a single fault doesn't kill power to the whole house.

Every upgrade is Part P certified and comes with an EICR for the affected circuits, so you've got proof of the work for insurance or if you sell up. If you're not sure whether yours needs doing, send us a photo of the board and we'll tell you straight rather than sending someone out to sell you a job you don't need.
