How much does it cost to rewire a house?
In Bristol, a full three-bed rewire costs £4,500 to £8,000 excluding VAT including a new consumer unit and certification; two-bed terraces start around £3,800 and large houses run past £8,000. National averages quoted online start lower because they assume empty properties and often exclude the consumer unit.
The number everyone searches has a wide honest range because houses vary on exactly the dimensions that cost money: size and circuit count, occupied versus empty (working around a family adds time), wall construction, and how much of the house was already renewed by past extensions.
What a real rewire price includes: strip-out of the old wiring, new cable to every point, a modern consumer unit with RCBO and surge protection, sockets and switches throughout, chases made good to plaster-ready, full testing and Part P certification. Quotes that undercut the market usually shed one of those quietly, most often the board or the making-good.
Partial rewires deserve more airtime than they get: where a loft conversion or extension already renewed part of the house properly, rewiring only the original circuits is often the honest recommendation, priced per circuit. Testing tells you which situation you have; guessing does not.
Timing advice that saves real money: rewire before decorating, and if a renovation is planned, rewire while walls and floors are open. The same job in a finished, furnished house costs meaningfully more, and the redecoration bill lands twice.
