What drives the price
- The size of the house: our reference is a 3-bed; flats run lower, 4-beds higher.
- Making good: chasing cables means replastering and redecorating afterwards.
- Living in the house during the work slows it down and adds cost.
- The consumer unit and certification are part of any honest quote.
All figures come from the same validated 2026 price data as the calculator above (sources: Checkatrade, MyJobQuote and comparable national 2026 cost guides, checked August 2026; see how we price), so this page and your estimate can never disagree.

Frequently asked questions
How do I know whether my house needs rewiring?
Age is the first clue: wiring older than about 30 years, a fuse box without RCDs, or any rubber or fabric-insulated cable means getting an EICR inspection (about 150 to 300 pounds) before you plan anything else. The report tells you whether it is a full or partial rewire.
Do these prices include VAT?
Yes, all ranges include 20% VAT. New builds and some energy-saving works can qualify for 0% or reduced VAT; ask your installer whether your project applies.
Why is London so much more expensive?
Labour is the driver: London trades charge roughly 25% above the national average, and parking, access and waste logistics add friction. Nationally this project runs £5,000 to £8,000; the calculator switches region in one click.
How accurate is this range?
It is a guide range from national 2026 cost guides, adjusted for finish level and region. Real quotes vary per trade, property and specification; treat it as a starting point, budget 10 to 15 percent contingency, and always get at least three itemised quotes.
