To: 9am on Wednesday 8th July 2026 (24hrs, UK time)

There will be a complete outage during this period.
During this maintenance window HMRC will be refreshing the below data held in TDR:

- Where applicable, aligning the CDS TDR environment to Production CDS 5.2.0 Release (which will take place on 4th July 2026)
- Refreshing Trader personal, account, and licensing data held in CDS TDR, using data which will be copied from Production on 7th July 2026

*Trader Dress Rehearsal is a sandbox environment and is regularly refreshed with Trader data and data from the Online Tariff on a given date, as such any CDS changes to Trader data in the live service or updates to the Online Tariff will not be reflected in TDR instantaneously.

HMRC wish to apologise for any inconvenience the period of downtime may cause whilst they undertake this important update, and appreciate your understanding.

This downtime does not affect live CDS declarations.

Kind regards
