What lease information is included?

Each record contains the lease commencement date, original term (typically 99, 125, or 999 years), and we calculate years remaining. Ground rent amounts are included where registered in the title. Not all titles contain complete ground rent information.

How does UPRN matching work?

Land Registry addresses are processed through our address resolution service, matching against Ordnance Survey AddressBase records. Match confidence scores indicate reliability, with 99%+ of leases successfully linked to their UPRN.

Why does the 80-year threshold matter?

Under leasehold reform legislation, lease extensions become significantly more expensive once the remaining term falls below 80 years due to 'marriage value' - the increase in property value from extending the lease. Identifying leases approaching this threshold is critical for buyers, lenders, and investors.
