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 Caerphilly 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 J28 / J32 (about 7 miles south) the Caerphilly 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.
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.
Common enough that we work on this stock most weeks. new-build estates in Bedwas, traditional valley terraces in Senghenydd, and detached homes towards Abertridwr — the new-build is a recognisable slice of that mix.
Service voids and pre-planned cable routes make additions straightforward — but the developer board is often the bottleneck. We mark the route at survey and price against it.
New-Build House stock isn't confined to Caerphilly — the same construction era shows up across Cardiff and Newport. We consolidate diary days across the postcode.
Short version: full property rewires on a new-build in Caerphilly works best when the survey accounts for modern cavity construction, the quote is fixed, and the materials (spare-way CU add) are matched to the stock — not lifted from a new-build spec.
New-Build House owners in Caerphilly usually want to know two things: will you know what you're looking at, and will the price be fixed. Yes to both — we work on this stock every week and price everything on paper.
