You should ask for recommendations from family, friends and neighbours when looking for a plumber to solve issues with your hot water radiators, or any other heating or plumbing problems you might have.
It is especially a good idea to speak to any tradespeople you might know even if they are from a different vocation – it is likely that builders, decorators and electricians, for instance, will have solid and reliable contacts within the plumbing trade that they will have worked alongside when completing jobs for clients.
