How Much Does House Rewiring Cost in the UK?
Typical range
£4,500 — £8,000
A full rewire of a typical three-bedroom UK house commonly costs £4,500 to £8,000, including a modern consumer unit, testing and certification. Property size, socket count, access and making good can move the total higher.
What this estimate assumes
A complete rewire of an 80–100m² three-bedroom house with standard access, a new consumer unit, a normal socket and lighting layout, and no major asbestos work.
Occupied homes, solid floors and restricted access raise labour time. London and South East quotes can exceed the top of this national range.

Frequently asked questions
How long does rewiring take?
Typically 5–10 working days for a 3-bed house.
Do I need to move out?
Not usually, but power will be off for parts of each day.
Does a rewire quote include plastering?
Usually only rough making good. Ask whether chases will be filled, skimmed or left ready for your decorator, and have that written into the scope.
What certificates should I receive?
You should receive an Electrical Installation Certificate and, for notifiable work in England and Wales, evidence of building-regulations notification.
