Excellent,excellent,excellent. Not often a tradesperson is happy to visit without cost to do an assessment of works required upfront and then give s reasonable quote and also explain possible options. Needed a new consumer unit (fuse box to us laypeople) to replace my ancient one and do an EICR. Based on the quote for the work I also added a hard wired for alarm and some smaller jobs as well. Very polite, cleaned up after the works as well. I have already recommended him to a number of friends.

The standard of work was excellent - way better than I have ever experienced. I am so lucky to have found this company. Always on time, turned up when expected - stayed late to finish, tidied up after themselves EVERY day - pleasant and courteous and excellent, excellent finish! I am really delighted and cannot recommend this Company enough. I have already had people around to look at the quality - it is seriously good.
