The insights to property lifecycles 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 1:1250 to 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.
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.
