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.
Two things dominate consumer unit upgrades on a new-build in Pontypridd: developer CU maxed out — no spare ways for an EV charger or garden feed, and no SPD retrofit, which the 2022 amendment now expects. Both are known variables on this stock, and both belong on the quote — not the invoice.
We work across CF37–CF38 weekly and see the same patterns street after street. That means the quote reflects real experience of this property type, not a template price.
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 (about 8 miles south) the Pontypridd 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.
spare-way CU add; SPD retrofit inside the existing enclosure; OCPP-compliant charger onto the developer stub. All on the written quote.
Almost never. A spare-way add on the side of the existing board plus an SPD retrofit covers 90% of new-build enquiries.
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. tightly-packed terraces along the Taff valley in Treforest and Cilfynydd, with student HMOs near the University of South Wales campus — the new-build is a recognisable slice of that mix.
