We got Djafar in to ugrade our fuse box and do a full rewire as part of a big renovation project. He also cleared out all the old wiring before starting - this was itself a pretty big job.
From beginning to end, Djafar was brilliant to work with. He always came when he said he was going to, arrived on time, and stuck to his original budget - which was very reasonable. He was worked around our schedule, which got a bit unpredictable in the weeks leading up to the final fix.
We're now living in the house, with everything working as it should be, and a certificate (which arrived quickly after the job had finished) to say that it's all been done to the correct standard.
Would definitely recommend!
