"TFS fitted a new boiler for us a few years ago and they service it every year, so we knew that the workmanship would be good. We were more than happy with the estimate, and the work done by George was absolutely brilliant. Overall I would highly recommend this firm, five star service."
"We've used TFS over the last few years, first making contact when we noticed a water leak upstairs. Neill and George traced the source and prevented further damage. They've serviced our boiler since, and replaced the fan when it broke. Willing to come out at short notice, even on a Saturday morning."
"My hot water wasn't working. Neill came out and identified the problem, ordered a part and temporarily fixed it so I had hot water again. One day later George came and fitted the new part. Excellent, friendly and reliable service as always."
"Worcester Bosch recommended TFS. I spoke to Neill and he arranged for George to come the next day. He spotted the condensate trap was blocked, repaired the boiler and did a full service. As an elderly customer living alone I felt real relief. I'm now in their system for an annual service — complete confidence."
"Rang TFS as the heating thermostat/boiler wasn't showing any signs of life. They said they'd call within an hour — I really didn't expect it to be so soon. George sorted the problem quickly and explained what it was. Professional, courteous and pleasant. Would certainly use them again."
"George came out to the property on time, very friendly, and carried out the required duties to issue a new landlord certificate. We previously used TFS to install a new combi boiler — everything was great, quick and hassle free. Payment is quick and easy, and they send reminders when our certificate is due to expire."
