The first-fix sparky vanished... and now nobody will sign off the job

Here's a situation I get called into more than you'd think, and it's nearly always a builder on the phone, not a homeowner. You brought a sparky in to first-fix an extension... chased the walls, ran the cables, dropped the back boxes, took a healthy chunk of the money up front... and then he went quiet. The plasterer's been and gone. Now you need second fix and a certificate to close the job out, and the man who did the wiring won't answer his phone.

Losing a trade mid-job is a nuisance on any site. A vanished first-fixer is a different animal, and it's worth knowing exactly why before you hand over a deposit.

The bit most people don't clock

The problem isn't just that you're a man down. It's that I generally can't fully certify a first fix I never saw.

An Electrical Installation Certificate isn't a rubber stamp on the finished room. It's a signed declaration, and the liability on it is limited to the work the person actually carried out and inspected. A big part of inspecting cables happens while they're still on show... before the plaster goes on. Once they're buried in your walls and under your floors, a newcomer can't see how they were run, clipped or terminated. So a replacement can't honestly put their name to the design and installation of wiring they never watched go in.

Why that stalls the whole job

That's the trap. It doesn't just cost you the second-fix labour and a fortnight of the programme. It can leave the electrics uncertifiable as they stand... no clean EIC, which means no straightforward building-control sign-off, which for a lot of developers means the final payment or the completion certificate sits stuck behind it.

A slow trade holds up a room. A missing first-fix certificate can hold up the money.

How not to end up here

Before you let anyone first-fix for you:

• Check they're registered with a competent person scheme... NAPIT or NICEIC. That's who notifies building control and issues the compliance certificate at the end.

• Agree in writing that the person doing first fix does second fix and the certification. One man, one number, start to finish... no handover for the paperwork to fall through.

• Don't pay the bulk before second fix. Stage the payments so finishing the job, and handing over the certificate, is in their interest as much as yours.

Already stuck?

If you're reading this with a half-wired extension and a sparky who's gone dark, the single biggest question is: has it been plastered yet?

• Not boarded or plastered... good news. Get a replacement in fast, while the cables are still on show. They can trace the runs, inspect, test and effectively take the installation over, then carry it through to a proper EIC.

• Already covered up... harder, but not hopeless. Talk to building control and the original electrician's scheme about what they'll accept. An EICR on the finished installation is strong evidence it's safe and to standard, even if it isn't the original certificate. Occasionally a section gets opened up to prove a point.

One man, both fixes

How I work on renovation and extension jobs across Maidenhead and the Thames Valley is deliberately boring: the electrician who chases your walls is the one who second-fixes and signs them off. A first-fix and rewire done that way can't be orphaned, because I'm the continuity... there's no gap for the certification to drop into.

I'm a NAPIT-registered electrician based in Slough, working with builders and renovators across Windsor, Maidenhead, Bracknell and the wider Thames Valley.

Far better we sort it before the plaster than after.
