So helpful & nice, explained everything to me & what was going to happen next realty great service

Lovely guy, He was very helpful and the quote was competitively priced. I was very impressed that he cleaned up after himself after completing the job. I have no hesitation in recommending this company, and I will use them again, should I need a reliable plumber.

Had a problem with my water tank as it wouldn’t stop filling up. Marco was the plumber who attended on both visits and he explained what the problem was and dealt with it very quickly and promptly, great service. Thanks Marco

Excellent customer service

Technician came on time and solved the issue professionally.

Excellent service, I contacted Grand Union online as I had discovered a minor leak out of normal working hours. I left a description of what was needed, Mitch phoned me the next morning with an available time slot and the problem was resolved within 24 hours. A job well done.

The engineer Marco was great. He persevered with a difficult problem.

First Class Plumbing from Mitch. He was very efficient and patient with us and explained as did the work. I would happily use Grand Union Plumbing and Heating Ltd - Definitely 5*****

Engineer was very polite, friendly and efficient service.

These guys have quite simply been elevated to my Go to engineers in MK whenever I have a boiler/radiator issue. Professional, helpful, swift and reasonably priced.
