How much does a house rewire cost in 2026?
A clear, honest breakdown of what drives the cost of a house rewire in the UK — and what to watch out for in a quote.
The honest answer: a full rewire of a typical three-bedroom UK home in 2026 usually falls between £4,500 and £8,500 including a new consumer unit, VAT and certification. Anything materially cheaper is either cutting corners on cabling, on the consumer unit, or on the making-good afterwards.
What actually drives the price
Number of rooms, ceiling height (bungalows are cheaper), whether floorboards are chipboard or tongue-and-groove, plaster type, the number of new lighting points, whether you want smart switching and USB-C sockets, and whether the property is occupied during works.
What a good quote includes
A room-by-room schedule, socket and switch counts, a specific consumer unit make/model, whether making-good (chasing and patching) is included, and a clear certification and Building Control notification line item.
Red flags
Vague day rates without a scope. 'Cash only' offers with no certification. Anyone who won't put a fixed price in writing. Any quote that skips the consumer unit — a rewire without a new board is not really a rewire.
