modern cavity construction, service voids designed in, plasterboard on dabs. Service voids and pre-planned cable routes make additions straightforward — but the developer board is often the bottleneck.
If you own a new-build in Cardiff and need full property rewires, the right spec is usually not the most expensive one. On this stock the sensible answer is spare-way CU add — matched to the wiring generation, not a lift-and-shift from a new-build brochure.
That is the standard we quote to. Fixed price, honest survey, SPD retrofit inside the existing enclosure, and paperwork the next EICR won't question.
Service voids and pre-planned cable routes make additions straightforward — but the developer board is often the bottleneck.
Wiring generation on this stock is typically current — often 17th or 18th Edition compliant at handover but with no headroom. On a new-build you should expect us to flag: developer CU maxed out — no spare ways for an EV charger or garden feed; no SPD retrofit, which the 2022 amendment now expects; EV cable stub left by the developer that terminates at an isolator, not a working charger.
Materials and methods we spec on new-build house work: spare-way CU add; SPD retrofit inside the existing enclosure; OCPP-compliant charger onto the developer stub. Everything is priced on the quote — nothing added on invoice.
Focus on the utility room or garage, the consumer unit location, and the intended cable route. Usually 15–30 minutes on-site or a short photo set.
Priced against your new-build's specific construction, not a template. Route sketched, materials listed, no line-item surprises.
Diary planned for the access constraint that matters on this stock — service voids and pre-planned cable routes make additions straightforward — but the developer board is often the bottleneck.
NICEIC certificate, photo evidence of hidden work, Part P where applicable — all emailed the evening the job signs off.
From M4 J32–J33 the Cardiff area, new-build addresses cluster in specific streets — we know the layouts before we walk in, which shortens the survey and firms up the quote.
"Quick, easy and clear with the process! Would definitely call out again for future work." — Lauren Filby, Sockets & Lights — Two Rooms
For a new-build usually yes — a 15-minute survey or a set of photos of the utility room or garage and the consumer unit is enough to write a fixed price.
spare-way CU add; SPD retrofit inside the existing enclosure; OCPP-compliant charger onto the developer stub. All on the written quote.
Two things: developer CU maxed out — no spare ways for an EV charger or garden feed, and the wiring generation — current — often 17th or 18th Edition compliant at handover but with no headroom. Both go on the quote, not the invoice.
Not unless the quote says so. On period stock in particular we route through floors, lofts and non-original plaster; cornices, dado rails and original panelling stay intact.
New-Build House stock isn't confined to Cardiff — the same construction era shows up across Penarth and Caerphilly. We consolidate diary days across the postcode.
Practical next step: photos of the utility room or garage or a 15-minute survey, fixed written quote back inside 24 hours, work booked around your add what the developer skipped. That's the whole process for a Cardiff new-build, on one page.
One local point of contact for new-build house work across Cardiff and the surrounding Penarth / Caerphilly area — quote, work, certificate and after-care.
