SSE are rubbish I have been paying a yearly fee of about £300 for a service and for boiler breakdown cover for many years with SSE. When my boiler stopped working called SSE within an hour engineer arrived, proceeded to work on the boiler. After about an hour engineer decided what the problem was and went away to find said part, leaving boiler in pieces on the kitchen worktop. Next I received a phone call quoting the part is obsolete. A week later through freezing conditions, a boiler in pieces, frozen pipes, no signs of an engineer. I have now located the part required myself and a gas safe engineer. This SSE contract is not worth the paper it's written on, avoid at all cost
