Trustindex verifies that the original source of the review is Checkatrade. Mark Foley has been really helpful for all of our plumbing/heating needs for several years. He’s very methodical, cleared issues with our boiler that several other call-outs failed to and always makes time to help out when urgent. Punctual and clear throughout. I’d recommend Mark to anyone.

We have had all new radiators with smart controls, a new boiler and new hot water tank installed by Mark. He worked quickly ensuring we had heating for the coldest weekend of the year. He left the house really clean and all the pipe work he has done is smart and tidy. His communication was clear and he is really to get hold of if needed. We wish we had found him sooner!
