We’ve recently completed a scheduled refresh of several key datasets. If you’re using AddressBase Premium, the latest version is now available for you to pull into your own systems.
We’ve also completed our monthly refresh of NHS DSE syndicated data, which includes information about hospitals, dentists, opticians, pharmacies and GPs.
In the works are the updates to CodePoint with Polygons and the next monthly NHS DSE syndicated data, scheduled for mid-October. Next in line are updates to OS MasterMap Topography, AddressBase Premium, CodePoint and CodePoint Open. These are scheduled for early November.
Keeping your data current is essential for maintaining the accuracy of your maps and services. These regular refreshes ensure you’re working with the most up-to-date information provided by the OS and other data suppliers like the NHS and the Department for Education.
What’s been updated?
Between 21 September and 02 October 2026, our team updated the following datasets:
- AddressBase Premium
- NHS DSE data
- GIAS data
These updates are part of our regular data maintenance cycle. We handle the heavy lifting of refreshing the data on our end so you can focus on using it.
How to get the latest data
If you’re an iShare in the Cloud (iSiC) or Astun Data Services (ADS) customer, you can access this refreshed data right away.
Most of our customers have scheduled iShare Studio workflow jobs set up to handle this. If you don’t, you’ll just need to manually run your existing jobs to pull the refreshed data into your environment. If you don’t have an existing job for this, you can create one following the documentation available in iShare Help .
We don’t expect any downtime while you update your records, so you can carry on with your day-to-day tasks as usual.
