Which? Trusted Traders2026-07-03“Paul arrived on time and communicated very well via email and text messaging to agree a time and date to service my 20 year old Bosch Worcester boiler. He did a thorough job of checking the boiler since it had been playing up during the cold spell earlier this year. He was very honest and at no point tried to sell me a new boiler, which to be honest I thought might be the outcome! I thoroughly recommend him for servicing boilers.”
