In reply to Choss:
I have mine insured under the Home Contents personal possessions section. There is a clause though, which states the gear is not covered while in use, so if my tent is stolen while it is up on a campsite, it isn't covered.
I had a claim through Aviva a few years ago when climbing kit, clothes, sleeping bag etc were stolen from a locked car in the Czech Republic. They settled this in a very fair way. I was pleasantly surprised.
