Compare Electricians: How to Choose One for Rewiring 2026 (UK)

Why electrician choice matters more than price for a rewire

A house rewire is notifiable work under Part P of the Building Regulations. If the electrician is not registered with a competent-person scheme — NICEIC, NAPIT or ELECSA — you must notify Building Control yourself and pay a separate inspection fee. A registered electrician self-certifies and issues the Electrical Installation Certificate (EIC), which is essential when you sell or remortgage.

What a good rewire quote includes

A complete rewire quote should list: new consumer unit (RCBOs preferred), replacement of all socket and lighting circuits, smoke and CO alarms wired to mains, full EICR test certificate on completion, building notification, and a schedule of making-good (plastering and redecoration). If any of these are missing, ask why.

Typical 2026 rewire costs by house size — and how to verify registration

Know the going rate before you compare electricians, so an unusually low quote stands out. For a full rewire in 2026, industry cost trackers put a one or two-bedroom flat at roughly £2,500–£4,000, a three-bedroom house at £3,500–£6,000, a four-bedroom house at £5,000–£9,000, and a five-bedroom or larger property at £7,000–£14,000. Add a London and South-East premium of 20–30%, and expect the lower end in the North of England and Scotland. Occupied homes cost more than empty ones because the work is slower and more dust protection is needed. For a fuller breakdown of labour, see our guide to what electricians charge in 2026.

Full rewire vs partial rewire

A full rewire replaces every cable, back box, socket, switch and light fitting plus a new consumer unit — usually needed on homes with rubber, lead or fabric-insulated wiring, or a fuse box with old rewireable fuses. A partial rewire updates only the circuits that fail testing (often the kitchen and bathroom) and reuses sound wiring elsewhere. A partial job is cheaper, but insist on a full EICR test first so you only pay to replace what genuinely needs replacing.

How to verify a competent-person registration

Do not rely on a logo on a van or website. Search the scheme's own online register by business name or postcode, then confirm the registration is current and covers domestic installation work. In England, Part P of the Building Regulations recognises five self-certification schemes, including NAPIT and Certsure (which runs NICEIC and ELECSA); the official rules are set out in the government's Approved Document P. You can confirm a firm is genuinely enrolled through the register at Electrical Safety First, or start your search through our vetted electrician service, before you sign anything.

Red flags when comparing quotes

• No written scope — only a single verbal price.
• Cash-only terms, a large deposit up front, or pressure to start immediately.
• No mention of an EIC, EICR or Building Control notification.
• Reluctance to give two recent rewire references or a scheme registration number.
• A quote more than 20% below the others with no explanation of what is left out.
