I have just had a combi boiler installed by British Gas to replace my back boiler. It was quite a big job to relocate and get a gas supply to the new location. I can't praise the engineers enough. They were polite, efficient and considerate. I was dreading having the work done as floor boards had to come up that were under my laminate flooring. Everything ran smoothly. These lads are a credit to British Gas. The new Hive control is amazing, so glad I took the plunge now before my old boiler died. Have been a British Gas customer for over 40 years, never had any major issues
