Have used Grand Union a number of times now, and they have been great every time. Unvented cylinder service this time, very easy to book online and was kept informed throughout the process, leading up to Marco's arrival. Marco arrived within the 3hr window, and was polite, friendly and efficient. Completed the service within 30mins with no issues or fuss. Will definitely book GUPH next year 👍🏻

All I can say is amazing, it’s taken a while for us to get around to flooring, so it’s a bit late. From start to finish we had amazing service. We knew what we wanted and Grand Union Plumming were the only company who made us feel like they could help. Glenn helped with the design, and when we were unsure of tiles met us at the shop to help us out. Harley fitted the bathroom and was great, showing us the work daily. If your looking for great service and a top level finish I would recommend Grand Union Plumming

After several unsuccessful attempts with other plumbers to fix our thermostat for the underfloor heating and balance the radiators, we were relieved when Mitchell from Grand Union Plumbing and Heating came over. He installed the thermostat for the underfloor heating and expertly balanced the radiators throughout the house. The difference was immediate, and everything is now working perfectly. We especially appreciated how Mitchell explained everything clearly without any jargon. Highly recommend!

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!
