Gas Bottle with some gas in (Exeter)

Hi there does anyone have a bottle with gas in their unlikely to use now? Maybe taking up space in garage or shed etc. I'm a unpaired carer, where I'm caring for someone has no mains electric or gas hence using gas bottle for little 2 ring hob but gas has run out and as I don't get paid,... money is non existent and it would make life nicer to be able to have something hot to eat or hot drink at short notice now it's winter....
