NCTS Phase 6 Implementation and Downtime 1st June 2026

The New Computerised Transit System, Phase 6 (NCTS6) is scheduled for deployment on Monday, 1 June 2026.

 

Planned downtime - 1 June 2026

To support the deployment of NCTS6, there will be a short period of downtime for both the Great Britain (GB) and Northern Ireland (XI) NCTS services:

 

Important information during downtime

Please ensure you follow the usual procedures for exports and imports, such as getting a Goods Movement Reference if moving via a GVMS location.

For departures, whilst NCTS is unavailable, we strongly recommend you avoid starting any movements under the normal procedure, which require attendance at Inland Border Facilities (IBFs) or ports.

If you must move goods during the downtime, please submit the relevant declarations prior to the beginning of the downtime. If you cannot submit declarations before the downtime begins, you may use the Business Continuity Procedure. However, we strongly advise against travelling to an IBF or port to start a transit movement until the system is back online.

For arrivals into GB or XI you should continue your movements as usual. Some transit processes, such as Office of Destination, may need to be completed when NCTS is available.

You can find the business continuity processes in the Transit Manual Supplement.
