We have been advised by the UKHO that Week 18 NMs for all ADRS products were not provided to those who update using the email, direct internet or web download update methods.

All ADRS users who have updated using the email, direct internet or web download between Week 18 and Week 23 will be affected by this issue, including those who updated via the Narrative Patch files.  The missing NMs have been added to email, direct internet or web download update methods as of Week 24, but affected users will need to take the action to ensure compliance.

Please refer to the instructions below which provide steps on how to identify if you are affected and how to get the missing ADRS data if required. If you are unable to perform either of the update options, ‘Section VI Week 18 NMs’ is noted below for your reference.
