Cost of Home Rewiring
across the UK

How much does home rewiring cost in the UK?

Home rewiring typically costs between £3,000 and £10,000 depending on property size and complexity. A small flat may cost £3,000–£5,000, whilst a three-bedroom house averages £6,000–£8,000. Large properties or those requiring extensive work can exceed £10,000. Costs include labour, materials, testing, and certification. Always obtain multiple quotes before committing.

What affects the cost of home rewiring?

Five key factors determine rewiring costs: property age (older properties cost more due to outdated systems), square footage and number of circuits needed, accessibility of existing wiring (concealed cables cost more to replace), material quality and cable types chosen, and whether asbestos removal is required. Local labour rates and electrician experience also influence final price significantly.

What does a home rewiring service actually include?

Home rewiring includes removing old wiring and replacing it with new cables throughout the property. Services encompass upgrading the consumer unit, installing new socket outlets and switches, testing all circuits for safety compliance, and providing Building Regulations certification. Decorative reinstatement of walls and plastering work may be optional extras charged separately by some electricians.

What is the difference between full rewiring and partial rewiring?

Full rewiring replaces all electrical cables and circuits throughout the entire property, whilst partial rewiring updates only specific areas or circuits needing modernisation. Partial rewiring suits homes with mixed-age systems and costs less, typically £1,500–£4,000. Full rewiring is safer for older properties and required by Building Regulations when selling or significantly renovating properties.

What should I check before hiring a home rewiring provider?

Verify the electrician holds current Part P certification or NICEIC/ELECSA registration, confirming they're competent to issue Building Regulations certificates. Check they have public liability insurance (minimum £6 million recommended). Request references, written quotes, and timescales. Confirm they'll provide an inspection report and completion certificate. Avoid unregistered traders offering suspiciously cheap quotes.

How long does home rewiring typically take?

Home rewiring duration depends on property size: small flats take five to ten working days, three-bedroom houses require ten to twenty days, and larger properties need three to four weeks. Complex jobs involving asbestos removal or structural issues extend timescales. Most electricians work Monday to Friday, so actual calendar time runs longer than working days quoted.

Does home rewiring need to be done by a certified electrician?

Yes, home rewiring must be completed by a qualified, registered electrician under UK Building Regulations Part P requirements. Only certified professionals can legally issue electrical installation condition reports and completion certificates. Unregistered work voids insurance claims, breaches regulations, and creates fire and electrocution hazards. Always hire NICEIC, ELECSA, or Part P-certified tradespeople only.
