Highlights
"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."
"On time,reliable and tidyu"
"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"

Smart checks
Before you hire an electrician
In 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.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
