I don't know what the nature of the business in question is - but consider that if you can have expenditure that's outside the scope of VAT, then somebody somewhere must be selling whatever goods or services to you that forms your non-VAT expenditure; logically, those sales must be outside the scope of VAT as well.
Insurance springs to mind, for example. (I've never done anything for any insurance companies or brokers, so my logic based assumption might be so wide of the mark it can't even see the mark on the horizon).
And now that I've mentioned insurance, I have a niggling little voice telling that at some point in the dim and distant past, NA_AA may have mentioned an working for an insurance broker. But I could just be making that up.
