Contracted Ashley Heating to perform 1st annual service on my gas boiler (installed by them last year which I was also happy with), and to recommission a gas fire I had not used for a number of years. Boiler and associated filter serviced to manufacturer's specs without fuss and paper records updated. Initial check on fire identified chimney blockage (bird's nest) so Steve explained he would not be able (legally and professionally) to recommission the fire and it would be a waste of my money paying for its service. He turned the gas off to the fire and attached a warning notice so it would be obvious not to use it at present. Once I've had the chimney swept I will be more than happy to ask Steve back to recommission my fire. Steve also pointed out and took time to explain I needed to unblock the air brick as the oxygen needs of the fire were greater than could be supplied by the air in the room without it. Confess I knew this as I had "draught proofed" room when I stopped using the fire a number of years ago, so I knew I would need to re-open the air brick as part of the recomissioning process, I just hadn't got round to doing this before Steve arrived. All things considered, Steve was very polite and professional when discussing what is essentially a non-compliance to regulations (knowingly) caused by me.
