Having done a lot of research on numerous plumbing companies to totally refit my bathroom I had quite a few personal recommendations from previous customers advised by and who had employed Cavendish Plumbing and who in the event did a very professional job at a reasonable price. They were on time at every arranged visit , cleaning each night leaving things very tidy for our use. Would not hesitate to recommend them to anyone if they require a reasonably priced bathroom conversation executed by very professional plumbers or for that matter not so extensive plumbing works.

Central Heating- 11 Nov 2019
Initially hired Loui to replace leaking radiator valves. The job ended up being bigger than we thought and our heating pump needed replacing and decided to install a magnaclean filter. A component of our boiler also needed replacing. On top of that We had our pipes flushed due to some radiators not heating up. What started out as a relatively small job we ended up having a number of things done. Loui and Paul were professional throughout the job and quoted a good price for work done. Will definitely go back to them for future jobs.

Quick to reply to my post and to organise his visit. Came when he said he would and he was very efficient. He put up all 3 of my radiators nice and quickly, asked me to check each one as he went to make sure I was happy. Tidied up after himself. Couldn't have asked for any more, very happy with price and the service. I will definitely use him again in the future.

I asked Tomasz to check our combi boiler as I’d been told by a different heating engineer, it needed replacing. Tomasz was very thorough and cleaned parts, others had omitted to do. He certainly knew what he was doing and said I did not need to replace the boiler. I was very impressed with his workmanship and his efficiency. I would not hesitate in hiring him again, he is friendly and honest.
