The team that arrived, were friendly, knowledgeable and trustworthy. They not only proceeded carefully, preparing my house to ensure the flooring was protected, they methodically carried out the work required. Resulting in my underfloor heating working perfectly, the first time since it was installed 3 years ago. I can’t believe we found these guys and that they are so close. Anybody that requires trustworthy plumbing experts, I thoroughly recommend.Response from the ownerThank you so much Danielle for your detailed review!

Many thanks Colin Cooper ★★★★★ Great fast serviceResponse from the ownerThank you for your feedback Colin 👌🏼😁 Cristiana Hrituc ★★★★★ Response from the ownerThank you Ana Borralho ★★★★★ Engineer was super friendly and very helpful. Sorted out an extra issue we had.Kept updated with times. In and out with job completed to a great standard.Response from the ownerThank you kindly 🙌🏼So great having feedback for our engineers / office staff Lisa-Jane ★★★★★ Very efficient professional service with good communication. Very impressed. Thank you!Response from the ownerThank you 👌🏼😁😁 Jim Baxter ★★★★★ A friend put me on to these guys. Not cheap but good is what he said. They turned up quickly to resolve a leak over the weekend though that isn’t officially part of the service. I then got them back to recommission the toilet that had leaked and they did that within a couple of days at a time when I couldn’t even get a response from other plumbers. I will certainly use them in the future. They might not be the cheapest but for piece of mind I think they are worth it.I have since used them to fit a new tap. Easy process to request a job using an online form. The office responds quickly with a quote and responds to questions quickly too. Booking them in is quick. They turn up on time, are polite and complete the job with the minimum of fuss. Next up is replacing my boiler.Update: since the items above they have fitted my boiler; sorted a leaking tap; fitted a couple of taps and wastes. Always on time, always reliable and nice to do business with. It is good to have a plumber you can rely on consistently.Response from the ownerThanks Jim for the lovely review. It's great to hear that we have been efficient and that you are pleased with the service. Look forward to working with you again. Dave Michele Byron ★★★★★ Wow! Great service.

In the last 6 months they have installed a new boiler for us, a new gas run, a new shower pump, and fixed our downstairs toilet. They also helped to re-pressurise our pool boiler and went out of their way to do this. Dave and his team were all extremely professional, polite, helpful and approachable. They treated our home very respectfully too, taking off their shoes before walking on any rugs or carpets, laying down protective film/blankets to protect floors, and cleaning up after themselves daily. I also found their prices to be very reasonable, particularly as you get the strength of a very big team behind the job - and they all pitch in together when needed to meet deadlines.I would thoroughly recommend them.Response from the ownerThank you Glen for this great feed-back. Appreciated and look forward to working with you again 🙌🏼 Jackie Kiely ★★★★★ A Professional, reliable, helpful and well organised company.Response from the owner👌🏼🙌🏼 Brian Cox ★★★★★ Friendly engineer who undertook a potentially messy job, very cleanly and efficiently.
