We have an LPG tank that was there when we moved in and an arrangement with a supplier that we also inherited. The supplier (I believe) rents the tank from Calor. Should we (could we?) own our own tank, or rent direct from calor and should we be ringing around all the suppliers every time we order? If so where can I find a list of suppliers and do they have to be local? Has anyone got a good deal on LPG?
