Highlights
"Mark replaced 6 LED downlighters and an extractor fan and fitted extra lights in the loft. He was very efficient, friendly and professional and I would recommend him."
"Excellent service and would recommend Mark without hesitation. Could not fault his promptness - arrived the same day as our call and did a thorough check of the faulty outlet in our kitchen. He explained everything clearly and was very friendly and professional. Issue was resolved straight away with replacement and tested to ensure issue was resolved."
"Mark was excellent. His response was prompt and communication timely and clear. He appeared to be thorough and demonstrated excellent knowledge in terms of identifying the problem - which he fixed and checked. He also provided an appraisal of further work which would be desirable to mitigate further issues down the line. I would have no hesitation in contacting him to undertake that work. Thank you Mark!"

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.
