“Finding a reliable plumber can be difficult but Flow Rate is the exception. The heating system was in need of a serious overhaul and Tony did a first rate job on it. Although it was a bigger job than originally expected they worked on into the evening to complete it - and for the quote provided.
Believe me this is a first class plumbing and heating company - I would always recommend to Businesses as well as anyone else!”
