How Much Does a Rewire Cost?

How much does a full house rewire cost in 2026?

A full house rewire in the UK typically costs between £3,500 and £8,000, depending on the size, age, and construction of your property. Here's a rough guide:

• 1-bed flat: £2,000–£3,500
• 2-bed terraced house: £3,000–£4,500
• 3-bed semi-detached: £3,500–£6,000
• 4-bed detached: £5,000–£8,000
• 5-bed detached: £7,000–£10,000+

What affects the price?

Property size and number of rooms, wall construction (plasterboard vs lath-and-plaster vs solid brick), number of circuits, sockets, and lighting points required, accessibility (loft space, under-floor access), the extent of making-good (first-fix plastering), and whether the consumer unit needs upgrading (it almost always does as part of a rewire).

What should be included in a rewire quote?

A comprehensive quote should include: new cabling throughout, a new consumer unit with RCD/RCBO protection, all sockets and switches, smoke and heat detectors, first-fix plastering of chased walls, full testing, NAPIT Part P certification, and building control notification.
