About full house rewire in Penzance
Penzance is a market town of around 21,000 in Cornwall. The housing is mostly period cottages, Edwardian villas and 1930s semi-detached housing alongside newer commuter developments. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like TR18 tend to be quicker jobs with standardised fittings. Local trade prices sit below the UK average. Lower contractor overheads and shorter distances across Cornwall do most of the work.
Bristol and Bath run hot. Step outside them and into Devon, Cornwall or rural Somerset and the supply thins out fast, especially for specialist trades like heat pumps or unvented cylinders. Lead times get longer the further west you go, and most firms will add travel if you're past the nearest big town.
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.
