英国贸易商支持服务（TSS）新平台上线

On 20 October 2026, the UK Trader Support Service (TSS) officially moved to a new platform with a new service provider. As a result, all Great Britain and Northern Ireland goods movements from this date onwards must now be submitted on the new platform.

HMRC has confirmed that customs processes and businesses' legal obligations stay the same. Only the platform and the way you access it have changed.

The previous TSS closes completely on 30 November 2026

The previous TSS no longer accepts new movements, but until 30 November 2026, you can use it for two specific things only:

• Closing outstanding Supplementary Declarations. A declaration isn't complete until it shows as ‘Closed’. Check each open declaration now and resolve whatever is stopping it from closing.
• Downloading your data. Save any declaration records you need. You can also get historical data through HMRC's Trade Reporting and Extracting (TRE) service.

You won't be able to access the previous TSS after 30 November, so we encourage action as soon as possible.

If you haven't finished moving to the new platform yet, check that you're fully enrolled. Make sure your company profile, users, authorisations (such as UKIMS), and agent relationships are correct. Get the latest news and information on the switchover via HMRC and NICTA.
