Has the gas annual check been more restricted. i.e. an analyser need to be used on the boilers to find out if they burn too much gas and if that is the case the boiler will be condemned. This is what I have been told by my gas engineer which frankly I do not . trust him easily as he has been trying to increase the charges for the last few years. For example last year he asked for more (more than £40 per check) claiming that he has moved out of town and it would cost him more for petrol.
