// WHAT'S IN IT

Inside the dataset

AddressBase Premium is the enterprise addressing tier. It includes everything in AddressBase Plus, plus the full lifecycle of every UPRN: provisional (planned), alternative (multiple valid forms), and historic (decommissioned) records.

If you operate a system of record - billing, taxation, electoral, healthcare - and need to reason about addresses through time (an address that existed in 2015 but doesn't now), Premium is the only product that gives you the full picture.

Key features

  • Full lifecycle: approved, provisional, alternative, historic
  • Every UPRN ever issued, retained
  • Cross-references between alternative addresses
  • Cross-reference to BLPU/LPI/PAF
  • Class codes for use type

// FAQ

Common questions

What's a "provisional" UPRN?

A UPRN issued for a property under construction - already valid for systems but not yet occupied or PAF-published.

How does Premium pair with our CRM?

We can run an address-matching service against your records that returns confidence-scored UPRN matches across alternative and historic forms.

Can we get just our LA area?

Yes - many councils licence Premium for just their administrative area.

Is this overkill for prop-tech?

For most prop-tech, AddressBase Plus is sufficient. Premium is right when address lifecycle drives business logic.
