Pricing factors
What affects the price?
Property size, age & type
A 1930s Berkhamsted semi with lath-and-plaster walls takes longer than a 2010s Bishop's Stortford new-build with plasterboard partitions. Rooms, floors and access all move the number — detached houses with garages usually add a day of cable pulling.
Existing wiring & fuseboard
Rubber cable from the '60s, aluminium from the '70s and rewireable fuses all need proper stripping-out — that's labour, not just materials. If a previous owner already part-rewired sensibly, we can often reuse cable runs and shave a day off.
Listed & conservation-area work
Chilterns cottages, Ware and Hertford conservation streets and listed homes across the county need minimally invasive routing: lifted floorboards, existing chases, skirting-board conduits. It's slower and pricier — but you keep your walls intact.
EV, garden and outbuilding circuits
Herts driveways mean EV chargers are the most-requested add-on we do. Garden offices, hot tubs, outdoor sockets and workshop supplies each need their own dedicated circuit — budget £250–£950 per addition depending on cable run.
Making good after the chases
We refill cable chases flush with bonding and finish sockets and switches level, but a decorator's second-fix (skim, paint, coving) is a separate trade. Some homeowners bundle a rewire with a full redecoration — we can coordinate the timing.
