On time and very polite. Explained everything. Would recommend!

Had a new boiler installed in Milton keynes. Thank you to Mitch. Really did a great job. Will for sure use grand union for our all gas and plumbing jobs in future

Fast, efficient, friendly and did good work for a good price

Amazing service, from the moment I called till the moment my bathtub was sorted. Would definitely recommend their services. Big thank you to Mitch.

Excellent service as always. Booked in a boiler service, the engineer attended promptly, was very professional and courteous and completed the service as needed. I’m so delighted to have found a plumbing company I can totally trust

We had a plumbing leak from the ceiling and found Grand Union Plumbing online. After checking out their reviews we decided to go with them. Lauren in the office was really helpful, and Marco came out to fix the problem. He was professional, explained what was wrong, and told us how he was going to fix it. The service was excellent —I can’t recommend them enough. They’re now the only plumbers we’ll ever call and use. Thanks guys!

Been maintaining boiler for past 5 years, always prompt , professional and courteous. Good value and excellent service.

Great company and very efficient work carried out, Luca did a great job with a difficult situation but fixed problem quickly and to a great standard..

Prompt, pleasant and efficient.

Service very professional and the plumber was very polite!

I booked Grand Union Plumbing & Heating to do a service of my very old boiler and radiators. They kept me informed of Marco's arrival times, which was so helpful and allowed me to work around the appointment. Marco was a pleasure to meet and he was friendly, answering all my questions with a smile. The service was quick and with a prompt turn around. I would definitely use Grand Union again and I would recommend them to my neighbours, colleagues and friends.

Professional company from start to finish. I booked a boiler service easily on line. Engineer advised of his arrival time on the day. Friendly, efficient enginner arrived. All certificates were emailed promptly afterwards too. Very happy customer 😀

We had an emergency where we had a slow leak causing a wet patch on our living room ceiling. I called in the morning and spoke to someone professional, and they arranged for an engineer to come out on the same day. Andy arrived promptly, was very professional and friendly, and explained the problem in terms I could understand. He was able to fix the issue within the hour and provided me with some tips for the future. I would recommend and will be using them again.

Marco texted with an estimated time of arrival. Arrived on time, very polite & chatted for a little while. Very tidy & completed job with no problems. Very happy. See you next year for my annual Boiler Service.

We're really pleased with our new bathroom. Glen and his team provided great service and quality of work. The breakdown of the works each day over the two weeks was really helpful. We'd like to give a special mention to Connor for his work ethic, standard of finish and cleanliness. Highly recommend and we hope to deal with Grand Union again in the future.

Highly recommend Grand Union Plumbing & Heating as they are really professional and they do good quality of work. Prices are really affordable. We are really happy and will definitely use them again and recommend them to all our friends and family.

A Very quick and prompt turn around with these guys, called them Monday, and they came out promptly to take a look, order the required parts and returned. A fast and speedy service! Update - Had a boiler replacement, took 4 hours and everything was left spotless. Really great work, british Gas advised a whole day with scaffolding work and none of that was required with these guys.

Marko came to service my Mum's boiler on the same day I phoned as also had a issue with the boiler. A Very professional service. Thanks

Grand Union plumbing & heating is the only plumbing company I'll ever use! Once again, they've exceeded my expectations. I had a broken thermostatic radiator valve in my daughter's bedroom and needed it fixed urgently before her return from university tomorrow. Marco arrived promptly within the scheduled time, was incredibly polite, friendly, and tidy. He clearly explained the issue and efficiently resolved it. My daughter's room is now perfectly warm, just in time for her homecoming. A truly excellent job, and a heartfelt thank you to Marco!

Terrific service, called in an emergency at 9am, and Andy turned up at 11am and 30 minutes later, all fixed. Great service with a polite and knowledgeable plumber.

4 taps replaced, very efficient, good communications, all neat and tidy

Technician was very thorough and pleasant. He even caught an unrelated issue. Brilliant man.

Carried out annual service check for gas central heating. Due to mix up at the office he was later arriving than scheduled but was efficient and tidy.

Great service, fast and on the time. I will use their services again in the future.

The engineer was very caring and respectful. The whole process was smooth and hassle-free. Highly recommend!

Very friendly and. Courteous. Let me know what was going on. Left job very clean and tidy. Any problems just call. All in all very satisfied..

Really great communication and a very efficient service. Marco was very polite, professional and most importantly sorted the issue. He cleaned up afterwards, was cheerful and helpful. I will be using Grand Union plumbing for all needs now.

Quality, prompt & fair value. We always use these guys

Punctual, polite and very professional. Great with keeping me updated and a quick turnaround. Very happy customer.

Always excellent service

Great experience with Grand Union over all. Use them for annual boiler serive. Also installed my Hive for me and looked into 1 or 2 other issues. Great and friendly team.

Simply brilliant. Very competitive price, arrived bang on time, extremely polite and courteous and above all (Thomaz) did a fantastic job and cleaned up before he left. No hesitation in 100% recommending them and will be sure to use their services again.

Great Service received! Highly recommend! Reasonable price for the works required. I had a prompt response to my query with a short wait time to the appointment. The text I got to say how far away they were so I knew when they were coming and it was accurate. Normally you don't get any warning from other companies. The guy was really nice and felt comfortable him being in the house. Definitely use them again for future works.

They've been servicing my boiler for years, and when I suddenly found that I had a leaking pipe under my floorboards, I turned to them for help. The carpet and floor had to be lifted, but after it was finished you would never know, it's as good as before. Great service and cheerful operatives every time 👍🏻😊

Absolutely great!

Needed an inspection done quickly of a hot water cylinder which had been flagged as a concern by a house survey we had done. Marco was absolutely fantastic. Carried out a full service, explained everything, and we had the report a few hours later. This was the second inspection we'd had to have done as the previous plumbers had been useless (different company). Marco also spent the time to talk us through a few other concerns we had and give us some idea of potential costs. Will definitely be hiring them to carry out the work once we've moved in!

Great service, very friendly and efficient. Would use again.

Excellent service, very knowledgeable and professional engineer

Great job. Marco was very helpful. I recommend them at any time.
