After weeks of chasing them up I get an email stating the boiler is BER beyond economical repair. Paying almost £35 a month for 3 years for what a yearly service where they don't note any faults or tell you about it and then when you put in a claim you are fobbed off with excuses. Avoid this company and stick to a reputable known insurance provider.
