What Our Customers Say

"Full Central Heating system upgrade scheduled to take place over four days. Steve and Mark worked like men possessed and completed the job with half a day to spare. Extremely friendly lads with a superb work ethic and very thorough. I couldn't be happier with the standard of the work and would recommend FG Welch without hesitation."
"We have used FG Welch for many years for our boiler servicing and the occasional breakdowns. They have always been extremely helpful and very professional. So when we made the decision to replace our ageing boiler they were obviously our first choice to do the job. The quote was very reasonable and boiler could be fitted on the date requested. The engineers who fitted the new boiler were excellent and carried out a very tidy installation. It was a pleasure to have them working in our house. I can highly recommend FG Welch and will continue to use them in the future."
"Excellent service provided by F G Welch in quickly organising an engineer to diagnose and fix a leak in my loft. I recommend this company."
"We were strongly recommended to consider F G Welch by friends when our central heating boiler needed replacing and we are very glad that we listened to them. Frank Welch arrived at the appointed time for a survey, listened to our concerns, advised, arranged necessary roof repairs and wrote a quotation out there and then. He clearly knew his business inside out. Steve and Mark turned up on the appointed day and worked hard, cheerfully and tidily to complete the job that day. They also knew their job like the back of their hands. We would use them again without any hesitation."
"We have been customers of FG Welch for over twenty years, having had repairs, new works, a boiler and maintenance over the years. The service is always five star, you can rely on Frank and his team to provide a reliable and prompt service whether the work is emergency or scheduled. We can highly recommend F G Welch."
"Just had a new boiler fitted brilliant work by Mark and Ben kept everything clean excellent job very pleased."
"Old boiler failed just before Christmas! Mr Welch came out quickly, weighed up the job, did a quotation and scheduled the work to be done as soon as possible. Work started 6th Jan and was finished the following day. The two lads who did the job Stephen and Mark were great and everything was put back and the house was left neat and tidy and of course WARM! Extremely pleased with the job and the way that it was done. Would recommend the company without hesitation."
