Quick answer
A full rewire typically costs £3,000–£8,000 for a 3-bedroom house depending on size, access, and location. It takes 5–10 days and requires Part P certification.
A full house rewire is a significant but important investment. For a standard 3-bedroom semi-detached house, expect to pay between £3,000 and £6,000. A larger detached house can cost £6,000–£10,000 or more. The cost covers all new cables throughout the house, a new consumer unit, new sockets and light fittings (unless you supply your own), and the Electrical Installation Certificate. The work takes 5–10 days for most houses and will involve some decoration damage as cables are run through walls and ceilings. Your electrician should make good minor damage, but you will likely need to redecorate afterwards. London and South East prices are typically 30–40% higher than the national average.
