Mitch replaced our boiler and ran new pipework, plus relocated some radiators. He did a brilliant job and I wouldn’t hesitate to recommend him! He was punctual, helpful and polite.

Suzanne Simmons

I had a new bathroom fitted by Mitch. He was absolutely excellent. He was polite, tidy and did an exceptional job. Reasonably priced too. 100% recommend.


Excellent service. I contacted them for a boiler repair. They responded within hours with prices. Once they confirmed part availability, they fitted within days.  Very efficient, great service and I liked their clear pricing.

Definitely recommend & I will be booking my annual service with them in future.

Well done!

Sheena Mac

Grand Union replaced our central heating system and in doing so we requested that it be relocated from the airing cupboard into the Garage.  The work was completed professionally & on time with the relocated pipework like a work of art, very neat and orderly.  I would have no issue with recommending Grand Union, and will certainly be using them for all our gas & plumbing needs.


I have called Mitch out twice since moving into our new house a month ago. Both times he has managed to fit in an appointment fairly quickly to resolve our issues. He has been professional and friendly, offering advice on other issues that I have seen. I would definitely recommend his services.

Definitely recommend these guys. Had a job done by them and they wasted no time to get it done and made sure I was completely happy before any payments. Nowadays companies just want to rush and take your money. Big thumps up

We always use Grand Union for serving and any other unforseen problems. The service and professionalism is 1st class. Would definitely recommend!!

A great company to do business with… I used them recently for an emergency with a domestic heating system which was rectified very efficiently. A second problem (some months later) and there was no decision to make, called them and they sorted it in no time with minimum fuss, mess and very reasonably priced.
