Jonathan is polite, professional and competitively priced. The consumer unit was swapped over and Jonathan arranged with E.ON to uprate our domestic supply fuse during the swap-over. We also asked advice about a faulty power socket (no earth) which Jonathan exchanged with a new one. Upon payment, I asked how much extra for the new power socket to which Jonathan said the original (low!) estimate still applied - I gave him a little extra ££ anyways. All-in-all, what you see is what you get with Jonathan, no drama, just gets on with the job. Will use again - highly recommended :-)
