Kind words from satisfied customers
Our boiler needed to be replaced urgently and I contacted Adam based on the ratings and reviews on Which trader. I found Adam to be professional and trustworthy. The work was completed on time and to an excellent standard. It was a home repair bill that I was actually happy to pay because the service was so good. I whole heartedly recommend Flush Ltd.
Change of Boiler and upgrade central heating system. Adam was absolutely brilliant he really put my wife and I's mind at ease having had cowboy/unreliable tradesmen in the past. Work was done to a high standard,was very clean and the quoted price was the price. (something we haven't had before!) Would highly recommend to anyone else. Thank you Adam!

Flush were incredibly responsive when we called up with a broken boiler situation. Someone came within two hours to check it. It turned out the boiler was bust, and Flush arranged for a new one to be installed just after the weekend. The team were courteous and it really felt like they had our back. I'd absolutely use them again for any boiler/plumbing work.
Customer in Greater London
I employed Flush Plumbing for my boiler installation after getting quotes from 5 local companies. Their quote was both the cheapest and also the most detailed. I found dealing with all at Flush a pleasure. Everyone who worked on the job was very professional and and I was very pleased with the final result. Adam was excellent at communicating how the work was going to be carried out and was happy to answer any questions I had. All his team were very polite and punctual. I will definitely be using Flush for future work in my property. I highly recommend them.
