Since October 2021, when I moved into this house, I have used JJB for work from a complete wiring check and a new consumer unit, to outside sockets, a car charging point, replacement of downlighters with LEDs to significant extra power sockets and loft and garage lighting. I have always found them to give clear technical advice, and be willing to consider and explain options. Their prices are reasonable and they come when they say they will, and do what they promise, and then clear up afterwards.
