“We moved into a house with a complex and poorly installed outdoor electrical lighting system. Dave did a great job of diagnosing what was salvageable from the old system and what needing replacing, with excellent communication throughout. Dave also was creative in solving issues we had (e.g., needing a high-power supply to an outdoor sauna). Strongly recommend Dave for any electrical works.”

Highlights
“We initially had an EICR check. This showed some work that needed to be done, which we were quoted for. We then had the work - fault finding in lights, replacing fuse box and some rewiring in kitchen David and the team were very good at explaining the work and costs. They were professional and diligent in the work carried out. Happy with what they did and will definitely use them again”

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.
