We are pleased to announce that we plan to release the updated version of the Postcode Profiler to the HEAT database in April. As well as updating the source data, we have made additional changes to enhance usability, which are listed below:
As per our Postcode Profiler Data Update detailing the incorporation of new English and Welsh Indices of Deprivation data, this refresh of the Postcode Profiler will see the relevant data points within the Postcode Profiler updated from the 2019 versions of the data to the new 2025 versions. This will impact the following metrics for both England and Wales:

The Postcode Profiler contains both a ‘Current’ and an ‘Archived’ version of the Indices of Deprivation fields, with the latter providing the metrics sourced from the second most recent version of the Indices of Deprivation. As such, in addition to the above, this update will also see the ‘Archived’ Indices of Deprivation be updated from the 2015 to the 2019 version for England, and from the 2014 to the 2019 version for Wales.
The planned update to the Scottish Indices of Deprivation is currently expected in late 2026, as per the following update: Our plans to update the Scottish Index of Multiple Deprivation.
