[Closed] House / bike insurance - who do you use?

I've been insured with M&S for the last few years which has covered every bike up to a £4k limit.

My insurance is up for renewal and in the new schedule I now have a exemption which says I can only claim up to £1k for any bike. I can only assume this is related to s bike claim I made 18 months ago following a garage break-in.

What are the other non-M&S options? I'm downsizing my collection but still have a Soda ~£3k, a Boardman commuter ~£1k, a road bike and a second commuter at ~£500 each so want to avoid getting them all insured seperately.

Thanks
