UPRN Matching for Local Authorities
Councils hold address data across dozens of systems — housing, revenues, planning, social care, environmental services. Semilariti standardises it all against your LLPG, at a fraction of the cost of traditional providers.
The Address Data Challenge for UK Councils
Local authorities are among the most address-data-intensive organisations in the UK. Every council service — housing allocations, council tax, planning applications, social care referrals, environmental enforcement — creates and updates address records. Over time, inconsistencies accumulate: the same property recorded differently across systems, duplicate records, legacy data that predates consistent formatting standards.
The consequence is real. Duplicated records waste officer time. Inconsistent address data prevents automated data sharing between systems. Addresses that don't match the LLPG can't be linked to the authoritative UPRN — breaking integrations and undermining data quality programmes.
How Semilariti Helps Councils
UPRN Assignment at Scale
Upload any address dataset — housing register, council tax roll, planning database — and receive back every record matched to its authoritative UPRN. Process thousands of records in minutes.
LLPG Alignment
Semilariti matches against databases derived from AddressBase, ensuring your operational data aligns with the national standard your LLPG contributes to.
Deduplication
Identify and flag duplicate property records across datasets — even when the same address has been recorded in multiple different formats.
Cross-System Consistency
Create a single authoritative UPRN reference for every property in your systems — enabling reliable data sharing across housing, revenues, planning, and social care.
System Migration Support
Migrating to a new platform? Use Semilariti to clean and UPRN-match your legacy address data before import — preventing historical data quality issues from carrying forward.
Confidence Scoring
Every matched record includes a confidence score. High-confidence matches are ready to use immediately. Lower-confidence records are flagged for your team to review.
Cost Comparison: Semilariti vs Traditional Providers
Traditional address data providers typically charge UK councils £20,000–£50,000 per year for AddressBase licences and associated matching services. Semilariti offers the same UPRN matching capability at a fraction of that cost — with no long-term contracts and no per-record fees for bulk processing.
