What's the cost to rewire a house in 2021?
Originally published 26 February 2021. Some figures and rules have since changed - see our latest guides.
The cost to rewire a house depends on its size, the number of rooms, and the sockets and power outlets required. Getting multiple quotes is recommended for accurate pricing.
The average cost to rewire a 2 to 3 bedroom house
Rewiring a 3-bed house could cost roughly between £2,500 and £4,500. Upgrading the electrical panel and improving access to wiring are additional expenses.
How is a rewiring project priced up?
Projects are costed per square foot based on the wiring needed. Phone lines and entertainment devices add extra cost due to structured wiring and data cables. Installation typically charges around one hour per 100 square feet, depending on the electrician’s experience. Fixed fees may apply for opening outlets and switches.
What does the rewiring process involve?
The process includes:
- Locating dry walls
- Opening walls
- Removing old wires
- Running through new wires
- Closing walls
Are the wires always run through walls?
Drywalls offer the best route, but wires can run through floor joists, attics, basements or crawl spaces. Alternative routing may take longer due to access limitations.
How long does it take to rewire a house?
Completion time depends on house size and the number of electricians involved. It could take anything between 5 and 10 days.
