Royal Mail and 
The Windsor Framework

The Windsor Framework, the agreement between the UK and the EU amending the Northern Ireland Protocol and the legal instruments which sit beneath it, including but not limited to statutory guidance, comes into effect from 31 March 2025. We would encourage customers to familiarise themselves with the requirements. The Windsor Framework does not affect goods movements from Northern Ireland to Great Britain or from Northern Ireland to Northern Ireland.

While we will provide further information on the detailed timeline for the coming into effect of the new arrangements in due course, businesses should be fully prepared for them by 31 March 2025.

The Windsor Framework will come into effect from 31 March 2025. The regulations for sending goods from Great Britain to Northern Ireland will change. Customers sending goods must provide additional data depending on whether the parcel is a Business to Consumer (B2C), Consumer to Consumer (C2C), Consumer to Business (C2B) or Business to Business (B2B).

The Government recently confirmed the Windsor Framework will come into effect from 31 March 2025. You can continue to send goods from Great Britain to Northern Ireland with Royal Mail as you do today until the arrangements come into force. 

We continue to work with the Government to ensure that goods from Great Britain to Northern Ireland will continue to flow smoothly and efficiently throughout the transition.  We will work with you to ensure we are well placed to manage the impact of any required changes. 

We will share further information with you as soon as we can. 

Please follow these links for the latest government updates:

For business to business (B2B) movements from Great Britain to Northern Ireland, Royal Mail will initially only move goods classified as ‘not at risk’. B2B goods movements classified as ‘not at risk’ with a total goods value up to and including £135 do not require a UKIMS registration. We recommend business customers familiarise themselves with the requirements around the UKIMS scheme. 

All Prohibited and Restricted goods movements will need to comply with Royal Mail’s lists, available on our website, and you and the recipient will need to meet the relevant data requirements for this traffic type. 

If you have B2B goods to send from Great Britain to Northern Ireland which are classified as ‘at risk’ we may be able to carry these goods on a Parcelforce Worldwide service. For account enquiries, please contact 03448 429102.

The new UK Internal Market Scheme (UKIMS) allows registered businesses to provide a reduced dataset when sending B2B parcels from Great Britain to Northern Ireland. UKIMS registration indicates the parcels being sent are categorised as ‘not at risk’ of entry into the EU.

UKIMS only applies to B2B movements. UKIMS-registered businesses will be required to provide a reduced dataset compared to businesses not UKIMS-registered. B2B goods movements categorised as ‘not at risk’ must be accompanied by a valid UKIMS registration.

Together with the reduced dataset requirements (compared to non-UKIMS B2B movements), a UKIMS registration will reduce the likelihood of goods movements being delayed or held for inspection, with potential custom charges applied.
