Distillers License
To produce Spirits in the UK by distilling alcoholic liquids or by any other process, such as cracking ethylene gas, you’ll need:
As well as a Distiller’s licence, you should apply to the National Registration Unit for approval of the plant and processes you intend to use in the manufacturing process.
Compounders License
If you distinctly alter the character or flavour of a spirit with another substance, other than water, but don’t use a still to do so, you need a compounder’s licence. (This doesn’t include mixed drinks solely for consumption on the premises, for example, cocktails).

HMRC Beer
If you produce Beer or Spirits for commercial reasons and its strength exceeds 1.2% ABV, you must pay Duty and register as a Brewer with HM Revenue and Customs (HMRC). Beer Duty doesn’t always have to be paid to HMRC immediately. If you produced no more than 60,000 hectolitres of beer in the previous calendar year, you might be entitled to a reduced duty rate.

UK Trade Tariff
Excise Duty is chargeable and any Customs Duty that may be due. These goods may be either UK origin, received following an intra EU movement or imported from outside the EU.
Different rates can apply to varying sub-categories of goods. In addition to the commodity description and code number, each excisable item has allocated a tax type code number (for example, 451 for spirits). These identify the type and rate of Excise Duty payable.
