Great, friendly company

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.

Great stuff from Grand Union Plumbing & Heating. All the best aspects of a large company (email confirmation, SMS on the day, SMS when engineer inbound, mobile payment friendly invoices) but also all the best aspects of a small business (friendly, personal, advice, discussion on any questions, flexibility). Work was top notch. You can't go wrong with these guys.

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

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.

Mitch and Andy from Grand Union really…

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.

Punctual, Efficient & Trustworthy service.

I’ve been using Grand Union for a few years now for Boiler install/ service, radiator install, heating system maintenance & any other plumbing needs. Their prices are reasonable, service provided is friendly, prompt, tidy & more importantly punctual. Digital payment methods make it that much easier. Fantastic service provided by Andy & especially Mitch who is quick is responding even on WhatsApp.
