How much does it cost to rewire a house in the UK? (2026)
The cost to rewire a house in the UK typically ranges from £2,500 to £12,000 depending on the size of the property and the scope of work. A full rewire on a typical 3-bedroom semi-detached house costs around £3,850–£7,260 including all materials, labour, testing, and certification.
A consumer unit (fuse board) replacement alone costs considerably less — typically £300–£800 — and is a common first step when the consumer unit is old or lacks RCD protection but the wiring itself is still sound.
Why do rewire prices vary?
The biggest variables are property size (more bedrooms mean more circuits and cable), property type (detached houses typically require more cable runs and therefore more labour than terraced properties), and access — older properties with solid walls or complex layouts take significantly longer to first fix than modern timber-frame homes.
Location also matters — electricians in London and the South East typically charge 20% more than the national average. Additionally, the condition of existing wiring affects cost: a property with asbestos or lead-sheathed wiring requires special disposal procedures that add to the price.
How to find a good electrician
Always use an electrician registered with a Government-approved competent person scheme — NICEIC, NAPIT, or ELECSA. This ensures they can self-certify their work to Building Regulations and issue the required Electrical Installation Certificate (EIC) on completion.
