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.
The awkward part of consumer unit upgrades on a Barry new-build isn't the install — it's the route. Service voids and pre-planned cable routes make additions straightforward — but the developer board is often the bottleneck.
We map the route at survey, mark it up on a photo, and price against that specific plan. Nothing gets discovered mid-job that could have been priced at quote stage.
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.
In the Barry 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.
No — surveys for Barry new-build enquiries are free. You only pay once the fixed-price scope is agreed.
Almost never. A spare-way add on the side of the existing board plus an SPD retrofit covers 90% of new-build enquiries.
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.
New-Build House stock isn't confined to Barry — the same construction era shows up across Penarth and Cardiff. We consolidate diary days across the postcode.
Short version: consumer unit upgrades on a new-build in Barry 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 Barry 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.
