Hiscox is worth a look. I have contents unlimited cover and up to several thousand per bike, without being named/ itemised. Costs a bit over 200 pounds per year. I think the key is that I don't have any collections art or expensive jewellery /watches.
At least 4, can't remember if I declared or not. But they're definitely not itemised. The limit is either 2k or 3k each and you can cover more valuable bikes but do have to itemise. I have accidental damage and loss, and that includes forgetting to lock up and crashing in (non professional) races.
