How they can help you

Twinn’s own purpose-built, high-precision climate change data, Climate Risk Score, incorporates the latest OS data including all versions of AddressBase from Premium to AddressBase Core for the UK. We offer different licence structures, ranging from full corporate licences, to limited user licences and transactional pricing.

Climate Risk Score can be accessed as a full or partial database or via API or online portal. Twinn incorporates all relevant data updates into its solution. It also works with OS MasterMap data to deliver enhanced geospatial information to its customers. This includes features such as property extents and distance to key geographical points, locations, and features. OS mapping data is also at the heart of Twinn’s modelling processes and provides crucial insights into land-based features to inform certain hazard modelling parameters.

Twinn collaborates with customers in a diverse range of industries including insurance, banking, government, utilities, land and property, and supply chain and logistics.
