“Called up to ask about a fuse in the main fuse board as we went through a power tool cable and instead of coming out to look he very kindly talked us through finding a fuse along the route of the cable and we managed to swap it out and sort the issue, no stress, nothing to pay for his time over the phone! Couldn't ask for a better person.”
