Clare, I hava a Baxi Boiler. They do an insurance type scam which I had to take up recently. Annual charge of ?229 paid in monthly instalments and it covers the cost of any repair, parts and a new boiler if that is necessary. I think that compared to the hassle of finding and then paying exorbitant fees it kind of works out better for the cash flow. The only problem is it does not cover a service but I think you can pay a bit more and the plan does include an annual service.
