A full house rewire is a major undertaking, but it is one of the most important investments you can make in the safety and value of your home. Old or faulty wiring is a serious fire hazard, and a rewire will ensure your home is safe and compliant with current electrical regulations.
But what is the real cost of rewiring a house in the UK in 2026? This guide provides a detailed breakdown of the costs involved.
Average Cost to Rewire a House
The cost of a rewire depends on the size of your property, its age, and your location. On average, the cost to rewire a 3-bedroom house in the UK is between £3,500 and £6,000. [1]
Here is a rough guide to the costs for different property sizes:
| Property Size | Average Cost Range |
|---|---|
| 2-Bedroom House | £2,500 - £4,500 |
| 3-Bedroom House | £3,500 - £6,000 |
| 4-Bedroom House | £4,500 - £8,000+ |
| 5-Bedroom House | £6,000 - £10,000+ |
Factors That Affect the Cost of a Rewire
- The Size of Your Home: The larger your home, the more materials and labour will be required.
- The Age of Your Home: Older homes can be more challenging to work on, which can increase labour costs.
- Your Location: Electricians in London and the South East of England typically charge more than those in other parts of the UK.
- The Specification: The number of sockets, light fittings, and switches you require will also affect the final cost.
