Quick answer
Typically £500–£1,000 for a standard domestic installation, including labour, the unit, and certification. Larger properties or older wiring can cost more.
The cost of a new consumer unit (fuse box) in the UK typically ranges from £500 to £1,000 for a standard three-bedroom home. This includes the unit itself, the electrician's labour (usually 4–7 hours for two electricians), and the Electrical Installation Certificate. If your existing wiring needs work — for example, if circuits need re-cabling or the meter tails need upgrading — the cost will be higher. In London and the South East, prices are typically 20–30% higher than the national average. Always get at least two quotes from NICEIC or NAPIT registered electricians, and make sure the quote includes the certificate and Building Regulations notification.
