Basic foods are VAT free, but if you "add value" in any way, the resultant product may or may not be VAT free, so do check that for all the products you might want to sell. You'd have to charge more (or receive less net) for any which are VATable.
Also, make sure you've thought about future "gotchas", for instance if you subsequently decided to offer bed and breakfast, or camping barn accommodation or similar, those would now be VATable supplies as you are VAT registered. I don't know if you are able to de-register if at a point in the future it became better for you to be unregistered, so definitely check that side of things out too.
(Another example of a possible gotcha : At present jams and chutneys are VAT free, but if you later decided to run a small cafe, then all your food supplies could potentially become VATable.)
