I recently had a new boiler fitted to replace one over 30 years old. The whole process was simple, fully explained and with strict time guidelines. The engineer was polite, tidy, skillful and utterly professional. There were a number of unexpected issues due to the age and construction of my flat, necessitating laying new pipes in inaccessible places, yet he dealt with all of these with aplomb and on great time. It was a totally stress-free 2 days (for me) and I wish to thank British Gas for that. I have read other reviews which differ from my experience, so I thought it important to let you know how happy I have been throughout with how I was treated and how the work progressed.
