" Scott came out initially to look at a leaky water pipe for me. I called him and he fitted the job in at the end of the day. Whilst at my house ( a house I have bought but not yet move into) he carried out a gas safety check and discovered that it was unsafe. He capped it off for me and then arranged to return on the Saturday morning to trace the leak and fix it. He did the job quickly and efficiently . He was punctual, helpful , friendly and polite. I would definitely recommend him for any work you need doing. "
