About consumer unit (fuse box) replacement in Sevenoaks
Sevenoaks is a market town of around 29,000 in Kent. 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 TN13, TN14 tend to be quicker jobs with standardised fittings. Local trade prices sit on the expensive side for UK trade work. That's mostly wage levels plus the cost of running a van and a yard in and around Kent.
A lot of South East firms work both London and local jobs. Rates usually track London with a small discount, so you're rarely getting a bargain. Peak season runs May to September and good tradespeople can be three to four weeks out. Out of season is the time to price round.
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.
