A rewire is one of the biggest electrical jobs a home will ever need, and the quotes vary wildly. Here is what a full rewire actually costs in 2026 by property size, how long it takes, and why the lowest quote is usually the wrong one.
What a rewire costs
Cost tracks the size of the property and the number of circuits, sockets and light points. A one or two bed flat starts around £3,900 to £4,800. A typical three bed house runs from £4,450 to £8,000. A larger four or five bed home can reach £9,000 to £12,500.
Full or partial
A full rewire replaces all the wiring, consumer unit, sockets and switches. A partial rewire updates only certain circuits or rooms, which costs less but is only sensible when the rest of the wiring is genuinely sound. A good electrician will tell you honestly which you need rather than always selling the full job.
How long it takes
Expect four to seven days for a flat or small house, and up to two weeks for a large property. It is disruptive work that involves lifting floors and chasing walls, so factor in making good afterwards.
Why the cheapest quote is risky
A rewire is notifiable work that must be certified. A quote far below the others often leaves out the certificate, the making good, or the consumer unit, which all reappear as extras. Price the whole job, including certification and finishing, not just the wiring.
The sharp takeaway
Get two or three quotes, make sure each includes the certificate and the making good, and be wary of the outlier that looks too cheap. On a job this size, a verified electrician and a complete quote matter more than saving a few hundred pounds.
