I had a sevicing agreement with British gas.What a joke company? They failed to service the system properly resulting in several leaks in a short period of time.The engineer failed to check the heating system despite that it is supposed to be checked for safe working order as part of annual service. This company is a total digrace with a terrible attitude. Lying cheating scam company They attended my house agreed with me they at fault in front of 2 witnesses then went back and wrote a report full of lies about the damage their incompetent engineer did.Do not trust them
