Do not use. As many other reviewers on other websites, I had the experience being scammed (over a thousand pounds of damage). Didn't have hot water for a week during which the plumber came in at least 4 times, switched parts and charged us >1k. (Later it turned out none of these parts needed to be replaced). After yet another time they said a new part needs to be bought, I called another service, everything was fixed within an hour, no parts required. Called to submit a complaint and demand a refund, but they keep referring to other people who are "not available" and promise to call back. Never once anybody called back in 2 weeks. They also kept saying that they reply with resolutions to written complaints, but that is a a lie as well. I wasn't sure at first if that is incompetence or a scam, but after reading comments, it's pretty clear it is the latter.
