We called out the National Grid to our house (rented) because of a smell of gas. We are oil central heated, but when they got here they said our boiler was faulty and that it was leaking small amounts of harmful gases. Because they are an emergency service they wrote a small report, and put "do not use - UNSAFE" signs on the boiler and the flue, told us to evacuate the house and contact our agent in the morning.
We contacted the agent to do something about it and they have simply replied that the house is oil-central heated and therefore there is no possibility of a gas leakage.
Because it is only our word against theirs, I am not sure quite what to say. Am I being stupid? Can oil-fired central heating have a gas leak?
