or blocked off by an idiot roofer.A guy near me decided to replace his gas fire with an electric one as it was "faulty",I went round to give him some advice and enquired what was up with the gas fire.Apparently after it had been on for about half an hour it shut off and wouldn't light until you opened the door,A smoke test pointed to a blocked flue,a look on the roof revealed a 2x2 flag had been cemented over the "redundant" chimney by a roofer doing some repair work.Agree with you mate, its the same nightmare when a carry out gas inspections. One day a chimney could be clear the next day not so - falling debris, birds nesting etc
