Mitch did a brilliant job of fitting our new boiler, and continues to do a great job with the servicing every year. I would 100% recommend him!

Absolutely wonderful, from the day we arranged an appointment to the day our bathroom was finished. Mitch understood exactly what we wanted, listened, and made it happen. Danny our fitter went above and beyond and made sure that everything was perfect and went smoothly and the bathroom was finished perfect. the attention to detail was unbelievable, he was clean, tidy to the point we hardly knew he was there. I would definitely recommend them to friends and family, hopefully they get the same team we did.

Another annual service and check-up performed on my gas boiler and pressurised hot tank, by Mitch from Grand Union. Faultless service, reasonable prices, very professional - See you next year !

Fantastic service Arrived promptly and was professional and friendly Problem was resolved quickly Would definitely recommend and will be using again in the future.

Mitch and Andy from Grand Union really helped us out. After we had a dreadful experience with a Cowboy from a Milton Keynes Co. Called ‘MK Gas 24/7’ these guys came and put us in save hands again. I was so surprised at all the tests they did inside & outside my property, they were so professional, knowledgeable, friendly and kind. The first company had made our problem worse, so I’m really pleased I called Mitch who was not only able to sort it out, fix the gas supply & the boiler but make the gas safe again and not charge us a penny 😊 Top company, I would most definitely recommend Grand Union and call them again if we need them. Thank you Mitch & Andy.

Had to wait a couple of days, chased up and then seen very quickly. Clean, tidy and efficient, no problems. Definitely recommend.

Grand Union we’re brilliant. Had a leak under a concrete floor. They were prompt, efficient, friendly, courteous and kept me informed throughout. Highly recommend them and will definitely use again.

Really good, professional service. Would highly recommend

Recently moved home, needed a boiler system check, and a smart thermostat installed. These guys were punctual, knowledgeable and fair priced. Would highly recommend.

Mitch was really helpful and took time and trouble to find the best shower control regulator for me. His team provided a swift, very helpful and effective service at a fair price. I would certainly use Grand Union Plumbing again
