What affects the price
- •Number of bedrooms and total floor area.
- •Whether the house is empty or occupied — working around furniture and people slows it down.
- •How easily cables can be run — solid walls and no loft access mean more chasing and making good.
- •A new consumer unit and any earthing/bonding upgrades.
- •Making good plaster and redecoration afterwards (often a separate cost).
Regional price variation
Labour is the biggest regional swing. London and the South East typically run 20–30% above the national average, while the North of England, Scotland and Wales tend to sit 5–15% below it. Material prices are fairly consistent nationwide — it is day rates that move the total. The ranges on this page assume South of England pricing unless stated.

How much does it cost to rewire a house in the UK?
A full rewire typically costs £3,500–£6,500 for a 3-bed house, £2,500–£4,500 for a flat and £5,500–£9,000 for a 4-bed house, including a new consumer unit and electrical certification.
How long does it take to rewire a house?
A full rewire of a 3-bed house usually takes 5–10 working days. It is quicker and cheaper in an empty property, and slower in an occupied, furnished home.
Does a rewire include making good the plaster?
Not always. Electricians chase cables into the walls, but plastering over the chases and redecorating is often quoted separately — check whether your quote includes making good or just the electrical work.
