CDS Planned System Maintenance
We have been advised that due to scheduled maintenance the Customs Declaration Service (CDS) will be unavailable to all users on Wednesday, 29th April 2026 from 21:30 hrs until 23:00 hrs BST. During this period, the Customs Declaration Service (CDS) will be unavailable.
Declarations should not be submitted during the outage period.
Creating, updating, or embarking a goods movement reference (GMR) during this time might be affected.
Only goods with pre-lodged declarations attached to a GMR will be allowed to move using Goods Vehicle Movement Service (GVMS).
For guidance on GVMS, read https://www.gov.uk/guidance/goods-vehicle-movement-service-service-availability-and-issues
For import movements using GVMS, you should check the declaration status and arrive where needed https://www.gov.uk/guidance/manually-arrive-your-goods-in-the-uk
If moving consignments containing controlled goods with pre-lodged declarations, read the https://www.gov.uk/guidance/list-of-goods-imported-into-great-britain-from-the-eu-that-are-controlled and attend port inspection facilities or inland border facilities for goods to be inspected and released.
Exports should have Permission to Progress (P2P) before travelling.
HMRC apologise for any inconvenience this may cause.
