British film categories

As i have decided to make a British horror film, I have researched the categories of British film. They are as following:
Category A

Films where the cultural and financial impetus is from the UK and the majority of the personnel are British.

Category B

Majority UK Co-Productions. Films in which, though there are foreign partners, there is a UK cultural content and a significant amount of British finance and personnel.

Category C

Minority UK Co-Productions. Foreign (non US) films in which there is a small UK involvement in finance or personnel.

Category D

American films with a UK creative and/or minor financial involvement.

Category D1

American financed or part finance films made in the UK. Most films have a British cultural content.

Category D2

American films with some UK financial involvement.


My film would be a category A film, as all actors are British, the finance and location are British, and the personnel (all me) is British!
