I got David along to look at a problem with the earthing of my house which had been drawn to my attention when I had somebody in to fix a problem with my boiler. David showed up bang on time, looked at the problem and told me that this was really something the network supplier should sort and recommended having them do it. He said if I couldn't get them to fix it, he could do something but it probably wouldn't be as effective. He then said he would do me a quote. I told him I actually had the network people coming to do some other work (preparation for a Smart Meter) and he explained to me what I had to tell them. As he left I asked what the call out charge would be and he said "zero" he was just there to do a quote. I was really impressed that he both did the visit for free and that he was more interested in getting the best job done for me, than getting a job for himself. I'll definitely get him back in if I need more work done in the future. While he didn't do the work, I have rated him 5* for quality. He knew what needed done and ensured that I had the information available to allow me to get it done.
