I've now used JDW a couple of times.
One big job to rewire a garage conversion into an office, new consumer unit, lighting, sockets and testing. And a second time to relocate a socket and install another next to it on a very tight schedule to line up with work that another contractor was doing for us.

The level of work and attention to detail was outstanding, they make sure to understand the requirements, clean and neat and I'm certain their prices can't be beaten.

Safe to say I'll be returning to Dean and Jamie for any future electrical needs.
