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.

I’ve used Grand Union since I moved to Milton Keynes. I’ve had two traditional boilers replaced with combi boilers over a few years and the work done by Grand Union was exceptional, great service, quick to install and friendly from start to finish. I’ve had a number of small issues which naive been resolved over the phone and receive great service at a very fair price. Would highly recommend.

Really good really quick

Had an engineer come around for an annual gas and boiler service and he was professional in going about the job and prompt without any issues. Booking the appointment was hassle free as the communication was great.

Very prompt and honest. Did not do unnessary work which was my fault in explaining the job. Would recommend them without hesitation.

All good,great communication,easy to book appointment,polite and friendly engineer.

Fantastic service, friendly and very efficient. New boiler in less than 24 hours.

Grand Union do a grand job! They have been looking after the very quirky gas fired central heating system ( 19 rads) in our rambling three storey house in Stony Stratford for several years. Today, Andy was able to drain the system down, replace three TRVs and four corroded / leaky rad valves, and get the system back up and running with no air locks, all in a few hours. And left the place clean and tidy.

I needed my boiler to be serviced and to have it gas safety certificated. Marco from Grand Union P&H MK turned up on time very smart and polite. Quickly did the service, cleaned up after leaving no mes What more can you ask 100% would recommend

Had Marco to come and replace some bits on the boiler. A very efficient and clean worker. Top service thank you.

Grand Union Plumbing came to my rescue to fix a dripping shower after I had tried several other plumbers who either didn’t know how to fix it or didn’t show up. I found the staff at the end of the phone polite and very helpful. The booking process was easy and efficient. Tomasz the plumber arrived within the alotted time and was very pleasant. He worked neatly and carefully and overcame a few unexpected problems very well. I recommend Grand Union Plumbing and wouldn’t hesitate to call them again if I had a problem.

Prompt reliable service to replace kitchen tap and valve. Pleasant and helpful. Thank you.

Just had my central heating replaced, new boiler, radiators and pump replaced. The team were great, they turned up on time and kept me informed. Had an issue with the water circulating around all the radiators this was due to a build up of rust in the pipes from the previous radiators. Mitchell was like a dog with a bone to resolve the issue and it was all sorted. Thank You Mitch and Conner. Great service.

Great Service

Excellence

Have used Grand Union a number of times now, and they have been great every time. Unvented cylinder service this time, very easy to book online and was kept informed throughout the process, leading up to Marco's arrival. Marco arrived within the 3hr window, and was polite, friendly and efficient. Completed the service within 30mins with no issues or fuss. Will definitely book GUPH next year 👍🏻

Grand Union is always our first choice for all boiler and plumbing needs. Easy booking, reliable, great communication and fairly priced.

Quick, efficient service, provided me with 3 hour time window and another notification for 5-10mins before arrival

We had returned from holidays , house was a little chilled so went to put heating back on , and it would not warm up . Emailed and called grand union plumber, the young lady so polite and very helpful and explained our problem, also being pensioners so need house nice and warm. She organised for Andy to come and get all systems go for the heating by 3:30 pm Thank you so much for a quick response 👍👍 Definately five star service we got.

Great, efficient and friendly service.

Quick and easy gas safety check carried out. Friendly staff member, arrived at the time I'd requested to fit in with my working hours. Thank you.

Quick and efficient visit by Marco from Grand Union. He sorted out the problem with no fuss or mess.

All I can say is amazing, it’s taken a while for us to get around to flooring, so it’s a bit late. From start to finish we had amazing service. We knew what we wanted and Grand Union Plumming were the only company who made us feel like they could help. Glenn helped with the design, and when we were unsure of tiles met us at the shop to help us out. Harley fitted the bathroom and was great, showing us the work daily. If your looking for great service and a top level finish I would recommend Grand Union Plumming

Since our boiler was broken and we were without heat, Mitch arrived promptly and at very short notice. He was very thorough in addressing all of our inquiries and helped us set up our heating. Would definitely recommend them!

Marco came out today to look at our radiators that weren’t working. He found the issue and had it fixed within 10 minutes! Very polite and friendly, would recommend

Good professional service that I would highly recommend.

Great service from truly excellent plumbers. Andy and Mitch have never disappointed and always bring know-how, ideas and fast solutions. Great team.

After several unsuccessful attempts with other plumbers to fix our thermostat for the underfloor heating and balance the radiators, we were relieved when Mitchell from Grand Union Plumbing and Heating came over. He installed the thermostat for the underfloor heating and expertly balanced the radiators throughout the house. The difference was immediate, and everything is now working perfectly. We especially appreciated how Mitchell explained everything clearly without any jargon. Highly recommend!

Thank you Grand Union Plumbing & Heating you solved issues for us then charged a very transparent fair price and we could not be happier... we will be sure to use only your selves for any future work and boiler services.

Great service. Kept me advised all the way through , a pleasure to deal with.

I've had my boiler serviced by Grand Union Plumbing & Heating for around four years now and they've always done a great job and I would recommend them. It's easy to book a boiler service online, they always turn up when they say, and they do a great job. On the occasion I called for some specific boiler advice, they were very helpful and provided me with the service I needed.

Good service from start to finish. Very pleasant plumber and good organisation beforehand

Grand Union worked so fast and also tidy up as the same time.l Like their work 👍

Mitch and the team are the go to people for your plumbing needs. Very efficient service, have been using them for six years now.

New boiler fitted and amazing work! Everyone was brilliant to deal with and quote and job matched. It's always great to support a local business as well in the process which can provide a personal service.
