Thank you both for your replies. I am waiting for the 'gas safe' guy to ring me back to see what he suggests. I guess he will say a new one because of the age of it. I am wondering whether to replace it with an electric one,much easier but am not too keen on the fan heater they all seem to have, I love the realistic look the gas coals have - decisions decisions. Thank you too for the link Builder, the paint is a lot cheaper than I expected :o)
