New network throughout property installed
I had some old and tired electrics in the flat I own. J-Tech gave us a reasonable quote and an early start date. We were really pleased with their communication through the whole process. Given that I am not an electrician it was refreshing to see a complete breakdown of works carried out. I have copied and pasted part of the email I received covering the work done: [quote] I have completed the work at the flat and a couple of extra bits along the way. There was an extra broken socket in the lounge and there were two faults on circuits which have been found and rectified. Fill hole exposing cables on external fitting Replace light fitting in store area by front door Replace x2 double sockets in lounge Replace double socket adapter and install single socket in lounge Replace bathroom light Move cooker switch to below join and install blank plate Bond the water pipe Remove two fuse boards and condense into one tidy up area removing all unnecessary items and re install timer spur for off peak immersion Fix fault on circuit in bathroom circuit went to joint box in bathroom next to shower and socket in lounge cable removed and joint box removed from wall Fix fault on heater circuit changed switch and re terminated cables (did not have new switch so replaced with one from van) Test and provide EICR [end quote]
I can’t praise the helpfulness and expertise enough of all the team who did the electrical work for me. They went to great lengths to find the best solutions and to explain the work. They were punctual. They cleared up afterwards and the cost was very fair.I I am delighted with the result.

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.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
