I have two bikes, total value £1500, on my house contents insurance, . They jacked up the premium by £22. Compared to a bike specific policy, it's an absolute steal (sorry). The good bit is that they don't have the stupid, fraudulent weasel clauses about bike locks, abandonment, railway stations etc that the bike specific wallahs do. The downside is that if you claim for a bike, they will screw you on the house contents insurance premium when you renew.
Utter bastards and ragged spivs, the lot of them.
