10 Installation of New Combi Boiler system
Posted 23 October 2025
Pierre was very responsive despite being busy and came over at times agreed and also other times unprompted to clarify. A very old system needed removing and upgrading. Spent extra time making sure all installed correctly with one or two colleagues, and made sure working, and tidied up nicely afterwards. A nice and honourable guy and competitive quoteVerified reviewerJob location: SL2 10 Competent, reliable, friendly.

Posted 18 August 2025
I can't recommend Pierre enough for his professionalism and reliability. I had a previous boiler diagnosis and was told that I needed a new boiler but Pierre came around and recommended some parts replacement and a very reasonable quote for materials and labour. After Pierre diagnosed the boiler, he was over the next afternoon to complete the work. I also appreciated how Pierre talked through the parts that needed to be replaced, why and the comparison to the new parts. Excellent work and would recommend to others.Verified reviewerJob location: UB710 Fixed Kitchen sink leaking
