Further to my previous post about the different types of IVA, due to a complete lack of anything else more important to do this afternoon, I can now tell you that there is a third category of products which carry only 4% IVA, those which are considered essentials, such as: bread, milk, cheese, eggs, fruit & veg, books, newspapers, human medication, wheel chairs, prosthetics and VPO housing (subsidised, like council housing)
In the 7% category you will find: food not included in the previous category,entrance to theatres, circuses, cinemas, concerts etc., funeral services, hairdressers, dentists, new homes & garages (up to 2 per household!)
In the 16% category are: electrical goods, clothes, shoes, household goods, tobacco, alcoholic beverages and just about everything else!
I hope this is enlightening! I'm now off to see if i can find myself a Googlewhack. (Google it if you don't know what it is!)
