How to Hire a Trusted Electrician for Rewiring 2026 (UK)
The single most important check when hiring a rewiring electrician is registration with a competent-person scheme like NICEIC or NAPIT. A rewire is notifiable work under Part P of the Building Regulations, so the electrician must be able to self-certify and issue the right paperwork. Beyond that it is insurance, references and itemised quotes. Here is how to vet electricians properly and avoid the common rewiring scams.
Why registration matters most
A full or partial rewire is notifiable work under Part P. An electrician registered with a competent-person scheme (NICEIC, NAPIT, ELECSA) can self-certify the work and notify building control for you. Hire someone unregistered and you risk uncertified work that fails on a future sale and may not be safe.
What to check before you hire
Beyond scheme registration, confirm public liability insurance, ask for contactable references from recent rewires, and check reviews. A trustworthy electrician will happily show certificates and explain exactly what is included.
How to hire: the checklist
1. Check registration
Confirm NICEIC, NAPIT or equivalent registration so the work can be self-certified under Part P.
2. Verify insurance and references
Ask for public liability cover and references from recent rewiring jobs you can actually contact.
3. Get itemised quotes
Insist on written, itemised quotes covering scope, the consumer unit, making good and certification.
4. Agree scope and certification
Confirm staged payments and that you will receive an Electrical Installation Certificate on completion.
Rewiring scams to avoid
Watch for large cash deposits, pressure to start immediately, quotes far below the rest, no written contract, and reluctance to provide scheme registration numbers you can verify. Genuine electricians are transparent about accreditation and staged payments.
