How Much Does a House Rewire Cost in 2026? (UK)
A full house rewire typically costs £3,500–£9,000+ in 2026. Price depends mainly on the size of the property and the number of rooms and circuits. A two-bed flat starts around £3,500, a three-bed semi runs £5,000–£7,000, and a large four-bed house can exceed £9,000 once making good is included. Here is the full UK breakdown.
House rewire cost by property size (2026)
Rewiring cost scales with the number of rooms and circuits. As a 2026 UK guide: a 1–2 bed flat costs around £3,500–£4,500, a 3-bed semi runs £5,000–£7,000, and a 4–5 bed house can reach £8,000–£9,000+. These figures include a new consumer unit, new cabling, sockets, switches and certification.
What affects the price
Key drivers are property size, number of sockets and circuits, ease of access (whether floors and walls are easy to lift and chase), and the level of making good required afterwards. Older properties with solid walls or limited access take longer and cost more.
Don't forget making good
The headline electrical quote often excludes plastering and redecoration after chasing cables into walls. Always check whether making good is included, as it can add a meaningful sum. A full rewire usually takes 5–10 days depending on size.
How to budget step by step
1. Count rooms and circuits
More rooms and sockets increase labour and materials.
2. Decide on a full or partial rewire
A full rewire replaces everything; a partial targets specific circuits.
3. Factor in making good
Plastering and redecoration add to the electrical cost.
