I'm living in a residential area of semis and a house nearby is the registered address for a mobile catering company. I'm pretty sure there are quite a number of gas cylinders being stored in an outside shed there since I can frequently hear them being dragged around. I'm just wondering if anyone knows what the regulations are concerning non-domestic storage of gas cylinders and whether the storage etc should be inspected. In fairness, I don't know if they are full or not but it is a potential concern.
