Had a boiler service done... nice, friendly and punctual Was very helpful with advice and feedback Confident guys that know what they are doing and perform efficiently. Would recommend!
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.
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.
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
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*****
Amazing service. Thomaz arrived on time. 8.30am. Clean and tidy job. Can't praise this company highly enough. Fitted new toilet. Thank you. Value for money. 5 star.
We had a leak from the loft into the bedrooms and our current emergency cover with Anglian offered an unacceptably long response time, leaving our home at risk of flooding. Thankfully I called Mitch, who quickly arranged for someone to come out.They identified the issue and repaired the pipe promptly. The service was exceptional-fast,professional and greatly appreciated.
Tomasz was polite, friendly, tidy and efficient when replacing our bathroom tap. Thank you for the excellent service.

Had Grand Union Plumbing and heating fit my new shower today. Not only was it done swiftly with no fuss but provided as well with a great fitter who cleaned up everything and made sure I was OK with the controls. Brilliant quick service at very good price. Thank you.
Grand Union redid our bathroom for us. Great experience from beginning to end, very professional and bathroom looks brilliant. Thanks again to Harley, Mitchell and the team!
Thank you Marco for replacing our kitchen tap. Prompt, professional, friendly and reasonably priced. Definitely recommend this company to all. Fenny Stratford
This was a return visit to replace some parts on the boiler. They were their usual high professional selves from making the appointment to fit in with me, notification of ETA of when Marco would arrive, which is always useful and, impressively, they stick to it. Job was done efficiently and everything left tidy. Very pleased.
I have always used Grand Union and will not use anyone else, they resolved a shower issue for me quickly, reliable and prompt as usual, thanks again.
From first contact with Mitch and then Lauren with regard to our plumbing issues it was clear that I was dealing with a very professional organisation who were interested to help solve our problems. The plumber Tomasz then did an excellent and fast job(s) fixing our two toilets. Highly recommended.

Careful planning and execution of work. Time taken to consult with creative solutions. Great service and responsible outcomes
From the initial phone call from GUP&H to book my appointment to repair the issue through to the site visit, I am over the moon with the service. I received a text to say the engineer was on his way. Very respectful of the property and gives feedback on the issue and next steps. Can’t ask for more. Great 😊
I love my new outside tap! Thank you. I look forward to future correspondence.
Very friendly customer service and great job by the workers A++++++ well recommended
Andy from Grand Union checks the boiler today. He demonstrates his ability and skill to have thorough checking on the boiler. He is attentive to details and responsive to our enquiries so that we can take action to report the problem to our developer accordingly. He is very nice and communicate effectively with us.
From start to finish, the Grand Union team were professional, helpful, polite, tidy and respectful. The design and install was smooth throughout the whole end to end process. We were kept fully informed at each stage, with the result being a stunning new bathroom which is better than we could have hoped for.
Harley did a fantastic job with our bathroom renovation. He made sure we are happy with all the details from start to finish. We are happy customers and would highly recommend this company. See their work from the attached images.
Gentleman was very nice and worked quickly and efficiently
A transformation beyond words! I wont put a photo if the before because yes, it really was that bad! Having put off doing the bathroom for a number of years it was time for the bath to go & for us to get a shower put in instead. The bathroom before was in a horrific state, shiplap panels on all the walls with painted over mosaic tiles… horrendous! What Mitch & his team pulled off was beyond what we could’ve ever dreamed of. Every tradesman that came in was respectable, conscientious & incredibly hard working & worked together to ensure we had the bathroom we wanted, nothing was too much to ask. If I could give them more than 5 stars I would because they absolutely deserve it!

Really helpful and friendly. Drained blocked outside. Turned out to be further down the road after they did investigating. Still tried to unblock despite it being housing association issue. Would definitely use again
They were friendly, but very professional, and very hard working. They did exactly what we asked them to do for a fair price, and we are very pleased with the results.
I had a tap which was leaking quite alot of water. I requested a quote online and was called back within the hour. I was asked to upload a picture of the tap and had a quote in under 30 mins. Once I had accepted the quote, I had a call to arrange a time and date which we were able to get a next day appointment. Absolutely amazing. Marco came out, was quick and efficient and now do not have a leaking tap. Thank you so much. Would highly recommend!
The service I have had from this team has been exceptional, not just a one off experience but for some years now. Each time I contact them the communication is polite, clear and informative. The engineers know their stuff and get jobs done quickly. If that were not enough their prices are reasonable too. Thank you Mitch, you and your team are providing an invaluable service.
Great service, kept me informed and very helpful. Gave me a price before the job.
Good service provided, have nothing to complain about. Efficient, quick, on time - well done
Very good communication and prompt. Happy with them and i do recommend
This is the 1st time using Grand Union for a heating problem, and definitely won't be the last, for all of our heating and plumbing issues. We received a message about 15 minutes prior to the engineer, Marcos arrival. Marco was extremely friendly, efficient and very knowledgeable of his trade. If all of Grand Unions engineers are as efficient as Marco, then we can highly recommend this company for all of your plumbing and heating needs. We'll definitely be using Grand Union for our next boiler service, and any other issues that might arise in the future.
Grand Union Plumbing are first class from the ease and friendliness of the booking right through to their perfect work

Marco came and fixed out tap/plumbing and was very efficient. He was also very chatty and honest about what needed to be done. Will be using this company again for any future needs.
Very efficient, nice and polite and honest about the work needed completing.
Great service. Tomasz was really good when job turned out to be bigger than expected. Would use again.
Always professional and friendly, either on the phone or in person. I have Andy fix my boiler quite often. He is a friendly guy and always knows exactly what is wrong with it. Highly recommend.
Good service once again. I have used this company a few times now and the service has been excellent. They are always willing to go the extra mile to solve the problem and understand the true meaning of customer service.
Fabulous bathroom installers! Super happy that we chose Grand Union Plumbing & Heating to install our new bathroom. Mitch, who heads up Grand Union, was very friendly and attentive as we talked through our design, offering sensible suggestions that complimented our design ideas well. He was then quick to provide a competitive quote and book us in. We had Connor fit our bathroom. Connor was fantastic - extremely hard working and meticulous; we knew everything was in safe hands. Moreover, he always took the time to clean up properly at the end of the day. Mitch coordinated the work outside the rip-out and installation phases and no suprise, he's got a great team of trusted electricians, plasterers, tilers and decorators that were also exceptional. All up, a really seamless process and we've got a new bathroom we're really happy with. If you're after a bathroom install do seriously consider Mitch, Connor and the team, we're already thinking about getting them back to do more work for us!
Grand union came out to do our yearly boiler service and arrived on time. Picked up on a faulty component during the service and the part was replaced within the hour. Great service and highly recommended. 5 stars
Tomasz did a fantastic job efficiently, was polite and kept us in touch with progress. Definitely I wil used that company again
Had a txt to say Andy was in way as he collected keys from work. Reliable and great customer service
Easy to book. Engineer called to say what time he would turn up. Completed the job and left no mess. Explained what he had done with photos. Friendly and knowledgeable person. Would definitely use them again. Excellent service.
Friendly and helpful. Took the time out to make sure everything was in working order once the work was complete. Much appreciated
The plumber is very good at what he does. Came on time and did an excellent job and very respectful . Show me very friendly. I recommend it and say you can trust. Thank you for brilliant job.
The company carried out Boiler service and gas safety checks. The service engineer came within the given time slot. The work done and the advised given was highly professional. I highly recommend this company.
Very professional plumber that helped us to replace our boiler and water tank with a combi in record time to minimise disruption to our tenants. They did a great job and for an affordable price. Not only that, they were very helpful to answer all our insurance (endless as usual) questions! Would recommend 100% !! Thanks so much for all your help
Great service From Scott and Craig Done my heating and plumbing. Cleaned up after jobs, explained everything being done thoughroly nice guys. Many thanks
Very prompt action. Nice services. The staff tidy up and clean the place after he repaired the taps. Also details explain the issue. Advised how it works after replacement. Thank you for the services.
Called my letting agent with a slight leak from the condensation pipe from the boiler, grand union came within 30 minutes and fixed it like new thanks. ☺️
Extremely reliable and high standard of work completed. From start to finish everything was communicated clearly, great service.
Excellent customer service Great workmanship, cleaned and tidied up after jobs and removed debris. We easily contacted and kept me informed as to what was happening. Good job reccomend
Marco kept us informed regarding arrival time and was spot on as usual. As with all of Mitch’s lads Marco is polite, friendly , professional with no bull along the way. Will always use Grand Union in future, if they can’t do a job Mitch always seems to know someone who can:)
Called last Monday as my boiler stopped working and didn’t have neither hot water nor heating. They were excellent giving different quotes and have done an amazing job. Everything was fixed in less than 2 days. Would definitely recommend them!
Scott visited us for solving an issue with our radiators. He was quick to identify the issue and gave us the estimate for the work to be done.
These guys really know what they’re doing, I had a problem with my heating control in that the smart device failed and I needed to get back to my original programmer which the smart device prevented me from doing. It took a while but Marco resolved the issue and tidied up the mess of wiring that the smart device installers had left.
Marco is very efficient, respectful and quick action to schedule the repair. His work was flawlessly done to our kitchen sink which was leaking. Had put all the parts newly installed in a good quality recommendation. Well done to the company for having him.
Arrived on time as specified, very polite and professional engineer, clean and tidy up after service 2nd time used and will be using again for any plumbing needs thank you
Really friendly team, engineer explained everything that was done in a clear manner, the boiler service was carried out quickly and efficiently
Used this company a lot, always good, always professional. Came to my rescue when my shower bust, fixed same day, reasonable price, Thanks Mitch and all the staff
Tomasz did a great job on your en-suite, we will be having Grand Union back for future jobs including a new bathroom!
I rarely complete reviews but this was a must. We had contacted GU for a service of our boiler. Marco literally came 3 hours later and completed one. Definitely the most efficient service I’ve used. Price was a lot cheaper than others too. Already recommended to a local friend who was looking for the same service. Thank you 👍🏽
Great experience with this project and great contact from start to finish .knowledgeable and friendly staff Turned up on time and very tidy with the work
I called GU when the controls of my elderly parents system packed up. Mitch came the next morning, found the problem and advised best solution to fix which he did the same morning. I couldn’t have asked for a more prompt, efficient and professional service.
Very friendly, supportive and reliable. I received a text message with a time slot and an ETA ahead of the driver arriving. Left the place as they found it. Have used for years and will use again. Highly recommended.

Really good work and prompt service by Scott. Already booked in another repair.
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.
Had a pressure drop in combi boiler from a leak.They were quick to respond, arrived on time as promised, polite professional service.
Not the first time I have used Grand Union , they are always on time with great communication, helpful guys who answer your question directly, clean and polite , thank you.
Mitch and all the guys are very professional and helpful. Unfortunately, I had a cowboy builder wreck my bathroom before Christmas leaving me with little facilities for a family of 7. GUPH worked really hard to get me a working bath and shower before the Christmas holidays. They are reasonably priced and a great team of people. I highly recommend and will only have Mitch and his team do any work for me in the future.
Very quick and efficient yearly service on the boiler. Friendly and efficient service and help with other jobs I need doing. Thank you
After 2 radiators leaked and had to be replaced within a couple of months, I asked Grand Union Plumbers to come and sort out a very cold house. Their engineer turned up on time, was very efficient, polite, clean and friendly and left the house nice and warm! Price was very reasonable and I wouldn't hesitate to recommend them!
Thank you Grand Union for fixing the boiler and get the heating and hot water on. Always a first class service from Mitch and Marco.
Quick response to our problem dealt in the most helpful manner , informed all along the way as to when the plumber was on his way and job carried out professionally. Very satisfied
All good,great communication,easy to book appointment,polite and friendly engineer.
Grand Union plumbing responded to my issue very quickly and efficiently. My kitchen tap had to be replaced and this was carried out within two days. Scott, the engineer was great at sorting the problem and left the area clean and tidy. I would recommend this company
Fantastic service, very thorough with the job & won’t leave the site in a hurry till full functionality of the fitted equipment is confirmed. Pricing is reasonable & out of hours service is also great. This is why I’ve stuck with Grand Union Plumbing for all heating & plumbing jobs since the last 6-7 years.
Incredible service. Instant response to our breakdown call. Fair price and great quality work. If only all tradespeople were as good as this. Highly recommend and will be using Grand Union for all my future servicing.
Professionals who know their work and deliver a high quality services!
Much thanks to Mitch for coming out at short notice. Very helpful from start to finish Highly recommend
Thank you Grand Union/Scot for fixing my heating/radiator problem quickly and efficiently. Scot diagnosed the problem, got the part needed & then fixed the radiator problem & left all working okay. Scot was also courteous, informative & respectful of my property. Would gladly & happily recommend Grand Union.
Very professional right from the beginning. Tomasz was polite and thorough with the job. Left it clean and tidy. Charges are bit more but they are honest and they give work guarantee. Plumbing and Heating company with a difference.
Requested and received a quote on the same day I submitted for a service to our Megaflo (Unvented Cylinder). Was then easily booked in at a convenient time on the same call. On the day, was contacted throughout to know everything was on track and when engineer was arriving. Work completed diligently, efficiently and with a smile. Would highly recommend Grand Union P&H and would definitely use again!
Great service. Mitchell was very helpful and solved our boiler issue. As we had no hot water or heating, Lauren was fantastic at sourcing a part at short notice that Mitchell kindly collected for the repair. Recommended service! Thank you.
Top rated service, 2 radiators installed and no issues. Would highly recommend. Third time using Mitch and will use again in future
Had Marco to come and replace some bits on the boiler. A very efficient and clean worker. Top service thank you.
My first experience with Grand Union was excellent. I enquired via the online form on their website and received a call from Mitch early the next morning. Later that afternoon he had diagnosed and resolved the issue that was causing my boiler to leak, and provided me with some useful information on my boiler, potential points of failure and how to spot the warning signs. With his help my ageing boiler will see me through another winter. I'll be asking GU to quote for a bigger project next year. Edited September 2025: Grand Union have just finished installing my new boiler; replacing an ancient conventional boiler system with a combi boiler. Three days of professional work, carried out to a really high standard. GU has delivered again and I couldn't be more pleased. Thank you!
Recently had a replacement boiler as our previous one was on it's last legs. Mitch provided us with a very reasonable quote in comparison with British Gas and helped guide us through our options. Always found other companies very pushy and seemingly trying to get as much money out of you as possible but that was not the case here, it was all clear and could tell the team just wanted us to get the best possible outcome which in our case saved a significant amount of money. Very professional service and friendly team all round. Work was completed to a very high standard and extremely happy with the outcome. They even checked in a few days after the work was completed to make sure everything was still ok. Would certainly recommend this company. Thank you for your hard work and excellent service.
We have used Grand Union Plumbing for various jobs now from Gas Safety Certification, radiator repairs to replacing a boiler. Always found them easy to deal with a good system for bookings and Mitch and everyone at Grand Union Plumbing helpful and respectful.
Professional, from start to job done. And price is transparent. Highly recommended. I will use their service again.
Quick response, punctual, efficient and analytical, picked up obscure issue very quickly, problem dealt with followed up some sound advice and help going forward. Great all round service
Faultless in every aspect. 5 stars for everything, would recommend to anyone
Quick and efficient. Very friendly as well.
Excellent service and good professional job. Tomasz is a credit to your business
Excellent communications and the work was carried out very efficiently and in a friendly manner. Good use of technology for booking an appointment and for payment.
Grand Union replaced an aging boiler and 3 x radiators at my house. The service was excellent throughout. Both Andy and Mitch were really helpful, tidy in their work and conscientious to get the job completed despite an "interesting" technical issue identified late on a Friday evening. I would recommend without any reservations.
Very delighted with the fast response to the work I needed in by bathroom, and I’m happy with the isolation of the shower. He was very professional and tidied up after himself, I would recommend him to anyone who needs work done.
Called last minute and so grateful got the job booked in. Tomasz was great fast professional tidy very helpful and a pleasure thanks all really pleased
Once again fabulous service from Grand Union. Mitch is so professional and did a great job installing a new radiator for us. The communication is really outstanding and the morning text confirming the booking then another when they are on the way is really welcome.
Prompt arrival after very short notice…. Andy was friendly, courteous and offered useful advice. Very helpful as this is my first annual boiler service in my new build property. Would strongly recommend!
Easy to book in job Always answer the phone Very competitive pricing
Tomasz was very respectful of our property, courteous & quickly replaced our leaky tap and checked there was no leaks before leaving.
We needed our boiler serviced fairly quickly as it was making lots of noise. I found Grand Union on Trustpilot for companies working in or near Newport Pagnell. I filled in the request form & Mitch phoned me very quickly & the service was booked for 2 days away. I had a message early in the morning & another one saying the engineer was due in 7 minutes. Andy serviced the boiler checking everything throughly & explained what he was doing. A really lovely man & I would recommend this nice company fully.
Mitch was prompt, professional and friendly and quickly located the problem with the boiler. He talked me through the whole process, showing me exactly what was wrong and how it could be mended. I was also impressed by the fact that, on the follow-on invoice, there were pictures of the work carried out - very good for my records. I'm glad Grand Union was recommended to me and I'm very happy to further recommend with five stars.
First time we used this company for a couple of relatively small jobs. We have already asked them to quote for something else and we are delighted to have finally found a reliable general plumbing firm. Big thanks.
Serviced system found water in side boiler checked it all and worked out it had come through the flue in last nights windy rain. Very happy.
Brilliant service and excellent staff ,friendly and reliant would definitely recommend this company to anyone with plumbing issues

Always my go to company for heating and boiler maintenance etc. They have 5 stars for a reason...they're good at what they do. Lauren the office manager is professional, fully customer focused and exceptionally proactive. She does what she says she's going to do. A rare thing. If you're looking for stuff to get done, these guys deliver.
A great company, all the members of the team are great from office staff to engineers. Could not recommend more! This company is so customer focused and will go above and beyond to help.
Came on time and very professional, picked up the problem. Will be coming back with part
Firstly I was impressed with the booking system at their website, then got even more impressed with the punctuality of the engineer. Boiler service was done very professionally and at very good rate. Definitely would recommend it to others and will be using this company in the future. Thank you Grand Union 🙂

We have used Grand Union Plumbing and Heating for years now and we always have an excellent experience. They are professional and punctual. Great service from them and they always service our boiler and cylinder with a smile. Thanks Andy and Mitch
Very professional and punctual. In less than an hour they serviced the cylinder, fixed the flush button and also repaired the pipes in the sink that was leaking water.
The whole process was seamless. I booked a boiler service on Grand Union’s website a week in advance and received texts on the day to let me know when an engineer would be round. Andy provided the boiler service and was really knowledgable and thorough. Would highly recommend!
Friendly, reliable and efficient.I would highly recommend Grand Union and Plumbing as they are masters in installation of unvented cylinders.
Friendly, knowledgable and tenacious in finding a part to fix my broken toilet, all the guys from Grand Union were excellent. Highly recommended
Reliable, friendly & always kept us updated. Would highly recommend!

"This is the 1st time using Grand Union for a heating problem, and definitely won't be the last, for all of our heating and plumbing issues.
We received a message about 15 minutes prior to the engineer, Marco, arrival.
Marco was extremely friendly, efficient and very knowledgeable of his trade. If all of Grand Unions engineers are as efficient as Marco, then we can highly recommend this company for all of your plumbing and heating needs.
We'll definitely be using Grand Union for our next boiler service, and any other issues that might arise in the future."
Andrew Dancey
"Marco serviced our boiler today, he fixed our toilet not so long ago so we have met him before.Really lovely man, friendly, helpful, nothing negative to say at all.The only reason for taking a star off was not knowing what time he was coming.When i booked the service I was told between 12.30 and 1.30pm, was also sent a text but was never given any window time so after 1.30 had to ring and was then told 1.30 to 3.30, so would of been helpful to of know this information previously."

Jessica Vallis
"Many thanks for responding and helping so quickly, I hear Andy was excellent and immediately sorted the issue with the boiler. Only reason I haven’t left a public review is because I already did one recently re the help you gave us with plumbing so was worried if I leave a second review it might get rejected. We will definitely recommend you and call on you again if anything arises."

"Many thanks for responding and helping so quickly, I hear Andy was excellent and immediately sorted the issue with the boiler. Only reason I haven’t left a public review is because I already did one recently re the help you gave us with plumbing so was worried if I leave a second review it might get rejected. We will definitely recommend you and call on you again if anything arises."
Emily Keane
"Excellent service, great communication throughout the repair process and great communication of the time of visit. Online communication was brilliant as it made it easier to arrange a visit when I couldn't answer the phone at work. Thanks again."
