AddressBase Change-only-updates (July 2013)

We are pleased to announce the release of Change Only Updates (COU) for AddressBase products this summer. Working closely with GeoPlace LLP to develop and create COU for the AddressBase product suite in both GML and CSV formats, COU will be available as part of the AddressBase six-weekly supply in the week beginning 8 July 2013.

The COU data consist of three indicators:

  • Updates
  • Inserts
  • Deletes

Applying COU from July 2013

If you wish to receive COU data, this is what you need to do.


To maximise the benefit of the July COU data, you should apply a full update to your AddressBase data holdings. This ensures you have a complete set of addresses to which to apply the COU information.

If you are contracted to receive COU supplies, you will automatically be sent a full supply of your AddressBase product area coverage of Epoch 15 from 28 May 2013, unless have specified otherwise, to be used as your baseline dataset.
