Full House Rewire in Cardiff works out at £3,080 to £7,920 per property in 2025, give or take.

About full house rewire in Cardiff
Cardiff is a large city of around 369,000 in Cardiff. The housing is mostly Victorian tenements, sandstone terraces and 20th-century estates typical of Scottish and Welsh urban centres. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like CF10, CF11, CF14 tend to be quicker jobs with standardised fittings. Local trade prices sit below the UK average. Lower contractor overheads and shorter distances across Cardiff do most of the work.
Welsh trade rates run roughly 10 to 15 percent below the UK average. Cardiff and Newport are fine for supply; rural West Wales, Gwynedd and Snowdonia can see longer lead times plus mileage added in. On renewables work, check for MCS specifically — plenty of firms have CITB and Gas Safe but MCS is a narrower group.
Anything notifiable (new circuits, consumer unit swaps, bathroom zones, EV chargers) falls under Part P and has to go through an NICEIC, NAPIT or ECA registered electrician. Day rates run £200 in the regions up to about £400 in London. If your sparky can't give you a Building Control certificate at the end of a rewire or CU change, walk away.
