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.

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

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!

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

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

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.

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.

Very pleased with new flush system in cistern, as the old one took ages to fill. Area left clean and tidy. Highly recommend Grand Union, would definitely use again.

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

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.

Mitch and his team are amazing. Mitch organised for a plumber called Thomasz to fit two Towel heaters. Thomasz was very friendly and very efficient in the way that he worked. Completed the job on time. I will need other work doing and will definitely call back Grand Union plumbing and heating.

My shower cubicle needed replacement, as the door had jammed. Grand Union Plumbing & Heating had done some good work for me in the past and were my go to company. I asked them to look at a replacement. They were professional, clean and friendly, all at a very reasonable cost. The work was difficult for their bathroom fitter but it wasn't for me. My bathroom looks amazing and the shower is perfect!

Helpful team

Friendly and professional service.

Great service. Arrived within the booking window. Kept up to date with arrival. Friendly and professional engineer. Thank you

Great communication from these guys, Gave me a 3 hour time slot on my chosen day and then the plumber gave me a courtesy message when he was on his way, Which is great when you’ve got kids. They guy came and did his inspection promptly and was very professional. 10/10

From the first point of contact to the end of the job, the service I received from Grand Union Plumbing and Heating was exceptional. The engineer arrived on time, was polite, very respectful of my home and went above and beyond to make sure I wouldn’t have any future problems with the heating. The work was carried out to a very high standard. I would have no hesitation recommending them to my friends and family.
