Good service .On time and professional

Easily booked a slot online. Engineer arrived on time and was efficient, quiet and tidy. Feedback sent online about tests was comprehensive. Payment online was easy. I used Grand Union last year too and will also be using them next year.

From start to finish, Grand Union were friendly and professional, with good communication and competitive prices. The engineer who visited our premises arrived on time, had a thorough understanding of the work required and completed it on time and to a high standard. Highly recommended!

As always Grand Union Plumbing did a great job. They ordered the parts required for my boiler fix. Let me know when they had arrived so that I could make an appt. They are very obliging and let me add another little job to my appt. Fixed my boiler, didn't leave any mess.

We had a good experience with Grand Union. The engineer was friendly and helpful. Would recommend.

Easy to book and appointment availability was excellent, kept well informed as to when the engineer was coming. Engineer also explained what it was the we needed to keep an eye on as well as show us pictures of before and after. Brilliant service at a resonance price, definitely returning👍👍

professional.efficient and quick

Great workmanship at reasonable prices. Very efficient booking process with useful updates via text of when engineer was attending appointment. Friendly and efficient service

Grand Union have serviced my boiler and replaced a faulty thermostat. Quick and efficient work. I am happy to recommend them.

Always good service from Grand Union. My ‘go to’ company for all our plumbing needs.

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.

On initial survey, very helpful, did full survey of property and explained what would happen next.

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.

Neat and tidy work.

Efficient service, polite and courteous engineer. Highly recommend.

Brilliant service form booking the visit to having our annual boiler check, friendly staff with great knowledge and advice will be booking them again next year

The worker have a good manner and skill set.

Fantastic company to deal with, and would not hesitate to recommend them.

Excellent friendly service from the team at Grand Union as always! Love their technology alerting the expected arrival time etc.

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!

Very helpful and quick response reasonable pricing.

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

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!

Great service, kept me informed and very helpful. Gave me a price before the job.

Responsive service, quality job, good value

Grand Union Plumbing are first class from the ease and friendliness of the booking right through to their perfect work

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.

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.

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.

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

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.

Great service From Scott and Craig Done my heating and plumbing. Cleaned up after jobs, explained everything being done thoughroly nice guys. Many thanks

Extremely reliable and high standard of work completed. From start to finish everything was communicated clearly, great service.

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:)

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

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.

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.

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

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.

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!

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

We had two engineers on different occasions Andy and Tomasz both were friendly and professional, got the job done

Fixed my shower leak, I was very happy with the service provided, plumber attending was very friendly and helpful, definitely use this company again 😊

Very good, very very quick got seem to within the day The gentleman that came out to do the job was very informative, and just let me know what he was going to do and left the place spotless when he left thank you very much
