Via the Northern Ireland Protocol (NIP), Northern Ireland operated under the EU VAT rules. There are revised VAT rules set out in The Windsor Framework. The EU rules on VAT rates will not apply to a list of goods for consumption in Northern Ireland in certain circumstances.
The Windsor Framework amends the legal text of the NIP to ensure that Northern Ireland will be subject to the same VAT and excise rules that apply in the rest of the UK. The Framework means that legislation to apply the zero-rate of VAT to energy saving materials can be introduced. Several other flexibilities should enable UK-wide VAT changes to apply in Northern Ireland. It is anticipated that future VAT issues can be addressed in order to manage any divergences in policy between GB and Northern Ireland.
