VAT is a tax on goods and services. Film Production Companies are not VAT exempt. Any VAT they incur can be reclaimed by filing a VAT return (which can be done on a monthly basis), but the actual VAT is not considered eligible expenditure for tax relief.

A ban on smoking in enclosed public spaces came into force in England on 1 July 2007. The ban applies to film sets just as it does to other venues, however, if an actor is required to smoke as part of his or her role, then there is an exemption to allow them to do so for that part of the shoot.

The regulations can be viewed in full at the Office of Public Sector Information website.
