I think this is covered by Public Liability Insurance - it's not very expensive and can get you cover up to around £5,000,000 normally.
Unfortunately it's all part of the litigous society we live in these days. The insurance won't only cover you against any claims from the venue due to damage, it'll also cover you against other 3rd party claims. The venue may sometimes ask for proof of this. Considering it's pretty cheap, I'd just get it for the peace of mind - that way if someone manages to set off sprinklers or something then you're covered as you are the hirer and responsible for the event

Make sure you talk to the venue to see what they expect covered (just furnishings, or other property?). They might be able to provide the cover for a small fee. They might just be asking for cover against 3rd party claims as they might have their own insurance for the venue and hired instruments.
