If the property has been altered, extended or let out, consumer unit upgrades on a new-build deserves more than a quick look. New-build CUs are compliant but full — the fix is usually a spare-way add and an SPD retrofit, not a swap. Property in Aberdare varies street to street, so the honest answer to "what will it cost" is that it depends on NICEIC certificate, photo evidence of hidden work, Part P — checkable in under an hour. It rarely surprises us; it often surprises the previous quote.
If the property is tenanted, the visit is arranged around access rather than around us, which usually means confirming times with whoever holds the keys. We would rather rule out certificate at the end, delivered early than discover it late. Consumer unit upgrades on a new-build is easy to get quoted badly and hard to get quoted honestly without looking at the installation first.
