Highlights
“Tony fitted a new Worcester Bosch Greenstar 24RI boiler for us in June 2025 having been referred to us by Worcester Bosch as a recommended installer in the Epsom area. Having had many problems when our previous boiler was installed by British Gas, we were slightly nervous. However we were very impressed by Tony and would recommend him without hesitation. He was prompt, thorough, friendly and left our house as clean as possible. We intend to use Keystone Comfort Solutions Ltd for the regular servicing of the boiler in future.”
“We needed a new boiler installer quickly before selling our flat as part of the deal negotiated by the buyer. Tony came to our rescue and quickly and efficiently installed a new Combi Boiler. Thanks very much Tony!”
“Tony was very swift to respond to my enquiry via trustatrader. It wasn't the simplistic diagnosis of the boiler problem but he clearly wanted to resolve my problem as economically and as quickly as he could. A part was needed, it was ordered quickly and a second appointment set up swiftly once part arrived. All quotes were spot on with no extras. I'd recommend Tony to anyone who needs a reliable and trustworthy plumber.”

Tony was quick to respond and attend to the problem. He explained clearly what was required and kept us informed about what to do if it recurred. We were very happy with the work he did.
