Worcester Bosch Boiler Installation in Milton Keynes

Types Of Boiler Explained:

Combi Boiler – Provides heat to radiators for central heating, hot water on demand so there is no need for a cylinder or water tank in the loft. Compact & efficient generally used in homes with one or two bathrooms.

System Boiler – Suitable for slightly larger homes with increased hot water demand, there is no water tank in the loft so this system will usually improve water pressure and will supply constant hot water to multiple taps at once.

Regular Boiler – Provides hot water through a cylinder which is supplied via a water tank in the loft, also suitable for homes with increased hot water demand.

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.
