For major businesses offering household services nationwide, taking AddressBase Islands means you have consistent property information for Northern Ireland, the Channel Islands and the Isle of Man on tap from a single source.
In the busy call centre environment, your staff will always get results no matter where the address is located, and because our data's regularly updated, your records will be more reliable, too.
Boost your marketing ROI. AddressBase Islands means you can run successful national campaigns - or build awareness in new markets, targeting households in properties converted into flats, for example.

Addressing beyond Great Britain
For the first time, AddressBase customers can access over 1 million extra records complete with the Unique Property Reference Number (UPRN), outside of Great Britain. Get a three-month free trial of AddressBase Islands data by signing up to our Data Exploration Licence.

Straightforward licensing
We offer the same style of licence for AddressBase Islands as existing AddressBase products. This ensures you can use your AddressBase Islands data in a consistent way across the United Kingdom and Crown Dependencies.

Available in two versions
AddressBase Islands is available in two versions, allowing you to attach it to your existing GB AddressBase product, whether that's AddressBase Plus or AddressBase Premium.

Simplified data management
Since AddressBase Islands brings together multiple data sources and is released alongside GB AddressBase products, your back office team saves time by managing just one data set each time instead of four.
