Owning your own home

Do you know off the top of your head what their max bike cost is? ie. single item limit?

I doubt there is one. You self declare each bike along with the value to replace it.
It covers most things, including racing. You pay by the month and it works on a sort of co-operative basis, if more people claim local to you, your monthly fee is higher and vice versa.

I probably live close enough to Hillingon crit circuit where everyone is racing* £5k+ wagons that it is rarely a cheap month.
