Consumer Unit Upgrades on a new-build in Cardiff is a physical problem before it is an electrical one. The stock is post-2005, walls are modern cavity construction, service voids designed in, plasterboard on dabs, and the practical constraint is that service voids and pre-planned cable routes make additions straightforward — but the developer board is often the bottleneck.

That shapes every line on the quote. We survey the utility room or garage, the cable route and the consumer unit location before pricing — because on this property type the standard scope is only standard once you know what you're working around.

What we build into every quote

Materials matched to the stock: spare-way CU add, plus SPD retrofit inside the existing enclosure.
Cable routing planned around modern cavity construction, service voids designed in, plasterboard on dabs — no chasing walls that don't take a chase, no mid-job "we couldn't get through".
Common new-build findings we flag before quoting: developer CU maxed out — no spare ways for an EV charger or garden feed.
Access constraints priced into the diary — a new-build in Cardiff isn't the same working day as a new-build with an empty garage.

Construction & access

Service voids and pre-planned cable routes make additions straightforward — but the developer board is often the bottleneck.

Wiring generation & likely findings

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 we spec

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.

What to expect

01
Photo or on-site survey
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.
02
Written fixed quote
Priced against your new-build's specific construction, not a template. Route sketched, materials listed, no line-item surprises.
03
Booked around access
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.
04
Certificate + evidence pack
NICEIC certificate, photo evidence of hidden work, Part P where applicable — all emailed the evening the job signs off.

Cardiff context

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.

FAQs — new-build house in Cardiff

How common is a new-build in Cardiff?+

Common enough that we work on this stock most weeks. a mix of Victorian and Edwardian terraces in Cathays and Roath, 1930s semis around Whitchurch, and modern estates in Pontprennau and Pentwyn — the new-build is a recognisable slice of that mix.

Do new-builds need a whole new consumer unit?+

Almost never. A spare-way add on the side of the existing board plus an SPD retrofit covers 90% of new-build enquiries.

How do you handle cable routing on a new-build?+

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.

Is there a call-out or survey fee?+

No — surveys for Cardiff new-build enquiries are free. You only pay once the fixed-price scope is agreed.

Do you need to see the property before quoting?+

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.

Summary

If you take one thing from this page: the awkward part is the routing, not the install. On a new-build, service voids and pre-planned cable routes make additions straightforward — but the developer board is often the bottleneck — that's what the quote should reflect.
