Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 13 years on the register also points to an established business rather than a brand-new one.

Highlights
“Great service start to finish. Had an issue with one light which was causing issues in another room intermittently. The electrician came in and was very thorough in his search for the fault - turned out to be more than one! He stayed to resolve the issue for us despite having other jobs to go to as well. Can't thank them enough for fixing this for us as it had been bugging us for months! Would highly recommend and will be the only electrician we use going forward.”
“Richard was amazing from start to finish. He came out and gave a quote and really understood the assignment and budget constraints. He proposed a viable solution and carried out quickly. On the day of installation he called to say he was 20 mins away, carried out the work without an issue. Highly recommended and have already passed his number on to friends and family.”

Electrical work in homes in England & Wales should be done by a registered competent person who can self-certify it meets the Part P safety rules. Check they're on the official register.
Check the electrical registerIn England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations. Confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done. It is your proof the work is safe and compliant, and you will need it if you ever sell.
