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.
How much does the region matter?
A lot: London typically runs 20 to 35 percent above the national average (this site plans with +25%, the quarter mentioned above), and the North of England, Scotland and Northern Ireland sit 10 to 20 percent below. The calculator adjusts for your region automatically, and the regional overview shows every factor.
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.
