A full rewire in London costs about £4,000 for a one-bed flat, £5,600 for a two-bed flat, £8,000 for a three-bed terrace and £10,500 for a four-bed house; the cheapest quotes come in 20 to 30 per cent under those figures and period houses above them. A partial rewire of one or two rooms runs £900 to £2,500. Plastering and decorating are extra.
| Job | London low | London typical | London high | UK typical | What moves the price |
|---|---|---|---|---|---|
| 1-bed flat, full rewire | £2,800 | £4,000 | £5,500 | £3,200 | 3 to 5 days; empty flats are 10 to 20 per cent cheaper |
| 2-bed flat, full rewire | £3,500 | £5,600 | £7,000 | £4,500 | 3 to 5 days |
| 3-bed terrace, full rewire | £4,500 | £8,100 | £9,500 | £6,500 | 5 to 7 days; Victorian solid brick and lath-and-plaster add 15 to 30 per cent |
| 4-bed house, full rewire | £6,500 | £10,500 | £13,000 | £8,500 | 7 to 10 days; 12 to 16 circuits |
| 5-bed or larger, full rewire | £9,500 | £13,000 | £18,000 | £10,500 | 10 to 15 days |
| Partial rewire (one or two rooms, or a kitchen) | £900 | £2,500 | £5,000 | £550 | Priced per room, £800 to £1,500 each |
A full rewire replaces every cable, socket, switch and light point in the home and ends with a new consumer unit; a partial rewire does the same for one floor or one room, usually a kitchen or an extension. It is due when the cables are pre-1970s rubber or cloth, when an EICR has coded the wiring C2, when lighting circuits have no earth, or when a renovation opens the walls anyway.
The electricians work room by room. A London flat takes three to five days, a terrace or semi five to seven, a detached house seven to ten, and a home that stays occupied through the work adds 20 to 40 per cent to the labour. The quote is for the electrical work only: chasing the walls is included, filling and skimming, painting, coving and flooring are not, and in London that adds £500 to £3,000 or more.
A rewire is notifiable under Part P. A registered electrician self-certifies and you receive an Electrical Installation Certificate and a Building Regulations compliance certificate; without them, a buyer's solicitor will ask for about £500 of testing later.

Plan for £8,000 to £9,500, against £4,500 at the very cheapest. Victorian houses cost more than the same size built later: solid brick walls, lath-and-plaster ceilings and suspended timber floors slow the chasing and the cable runs, and London firms put that at 15 to 30 per cent on top. Add £500 to £3,000 for making good.
Three to five days for a flat, five to seven for a terrace or semi, seven to ten for a detached house. You can stay, but expect no power in the rooms being worked on, furniture moved and floorboards up. Staying in adds 20 to 40 per cent to the labour; moving out for a week is often cheaper than it looks.
No. Rewiring quotes cover chasing the walls and filling to a skim-ready finish at best; plastering, painting, coving and flooring are separate trades. Get the words "skim-ready" in writing so the two trades do not argue over the join.
If the cables are pre-1970s, the sockets are the old round-pin type, or an EICR has several C2 codes across circuits, a full rewire is the honest answer. If one room or one floor is the problem, or you are extending, a partial rewire of £900 to £2,500 is normal; a good electrician will test first and tell you which.
An Electrical Installation Certificate for the whole installation and a Building Regulations compliance certificate from the electrician's registration scheme, because new circuits and a new consumer unit are notifiable under Part P. Keep both with the house documents.
