First Fix on a Rear Extension — Heaton Mersey, Stockport

A homeowner in Heaton Mersey, Stockport, recently completed the structural shell of a rear extension and brought us in for the electrical first fix. This is the rough-in stage of the electrical install — running all the cabling, fitting back boxes for sockets and switches, prepping for the consumer unit, and getting everything ready behind the walls before the plasterers move in.

For anyone unfamiliar with the trade term, "first fix" means everything that has to happen before the walls get plastered. Get it wrong at this stage and you're chasing it back out of the new walls a few weeks later — a costly, messy mistake that's entirely avoidable with proper planning up front.

On this Heaton Mersey extension we worked closely with the homeowner to plan the lighting layout, kitchen circuits, USB sockets where they'd actually be useful, future-proofing for an EV charger on the rear elevation, and a fresh sub-board feeding the new build off the existing consumer unit. Cables run cleanly, every box marked up, every junction labelled — so when we come back for second fix after plastering, fitting sockets, switches, and pendants is a fast, predictable day's work.

This is the kind of job we do regularly across Stockport and the wider Greater Manchester area. If you're planning an extension and you want the electrical work specified properly from day one — rather than bolted on at the end — get in touch. We'll walk the build with you, talk through circuit count, lighting layout, and any future-proofing (EV chargers, solar PV, smart-home prep) that's worth planning in now rather than retrofitting later.
