AddressBase Premium

Our flagship address database, AddressBase® Premium gives you the most up to date, accurate information about addresses, properties and land areas.

You'll be more efficient - making it easier and quicker to deliver a smooth service to your customers without postcode look-ups and address auto-completion for your websites. 

The insights to property life cycles you'll find within AddressBase Premium can give you all the information you need to shape the way you plan, operate and communicate with your audience.

At scales of 1:10,000, AddressBase Premium has all the information you'll need to conduct risk analysis at the level of individual addresses and spot patterns hidden in your own data.

Avoid errors, detect fraud

Knowing that 21 Croxton Road and Primrose Cottage are the same property, thanks to AddressBase Premium's alternative addresses, can be pivotal in fraud and risk detection - from mortgage applications to insurance claims on non-existent properties.

Planning ahead

Within AddressBase Premium, we've included the most accurate list of provisional addresses in Great Britain yet to be completed. This is vital in determining the size of new infrastructure needed to cater for population growth.

Content and context

From planning, throughout construction, occupation and any change of use and ending in demolition, AddressBase Premium is the most comprehensive view of Great Britain property life cycles.
