Darren came to service my boiler on Friday 16th June 2023. He found it to be 'dangerous' and had to condemn the boiler. This is obviously upsetting and a boiler is essential. Darren was very reassuring and said that whilst he was busy the following week he would come and fit a new boiler for me on the Sunday, for which I was very appreciative. He sourced and found me a new Boiler - the one I wanted - and he came, with a mate on the Sunday at 9am to fit the boiler and a new flue. The flue was very tricky to fit as it was over my conservatory which is hard to access. He sorted it. I was very impressed with the standard of his work and his professionalism. He is a perfectionist and I am very pleased with my new. efficient boiler and his work. They even cleaned up after them and took away my old, corroded boiler. Darren is an excellent Plumber and he explained everything to me, water pressure,how it works etc, and he even filled in the paperwork and registered it online so that I didn't have to worry about anything. I would not hesitate to recommend Darren Johnson for any kind of Plumbing work - especially fitting boilers!
