- Get at least 3 quotes from different tradespeople.
- Book during quieter periods (January–March for most trades).

Frequently asked questions
How much does it cost to rewire a house in the UK?
A 2-bedroom house rewire costs £3,000–£6,000. A 3-bedroom house costs £4,000–£8,000. A 4-bedroom house costs £6,000–£12,000. Prices include a new consumer unit, all wiring, sockets, switches and light fittings.
How long does a house rewire take?
A 2-bedroom house takes 3–5 days. A 3-bedroom house takes 5–7 days. A 4-bedroom house takes 7–10 days. The property is usually habitable during the rewire but expect disruption.
How do I know if my house needs rewiring?
Signs your house needs rewiring: rubber or fabric-insulated wiring (pre-1970s), round-pin sockets, fuse box with ceramic fuses, persistent tripping, burning smells, or an EICR (electrical inspection) that recommends rewiring.
Do I need an EICR after rewiring?
Yes. After a full rewire, your electrician will issue an Electrical Installation Certificate (EIC). An EICR (condition report) is then required every 10 years for owner-occupied homes, or every 5 years for rental properties.
Can I stay in my house during a rewire?
Yes, in most cases. Electricians work room by room, and you can usually use other parts of the house. However, expect dust, disruption, and periods without power. Some homeowners choose to stay elsewhere during the work.
