What UK Property Data Actually Exists in 2026: A Complete Inventory

How much data exists

The UK government publishes more property data than most people realise. The challenge has never been a shortage of data, it has been that the data is fragmented across dozens of registers, agencies, and local authorities, each with its own format, search interface, and update cycle.

This guide is an inventory of what currently exists for the 19.35 million properties in England and Wales.

Identification and address

• Ordnance Survey AddressBase: every addressable location in Great Britain with a UPRN. Around 40 million UPRNs in total.
• Royal Mail Postal Address File (PAF): every delivery point in the UK. Slightly different from AddressBase because it includes postal-only addresses.
• GeoPlace: the joint venture between Ordnance Survey and local authorities that maintains UPRN allocation.

Ownership and title

• HM Land Registry title register: the official record of registered ownership in England and Wales. Around 87% of land is registered; the rest is unregistered. Not all entries include a UPRN.
• HM Land Registry title plan: the boundary plan for each registered title.
• HM Land Registry Price Paid Data: every residential property transaction since January 1995 at market value. Updated monthly.
• Companies House: ownership of property held in company names.

Energy performance

• EPC Register: every Energy Performance Certificate issued in England and Wales since 2008. Around 25 million certificates have been issued (some properties have multiple over time).
• Display Energy Certificates (DEC): for public buildings.
• Air conditioning inspection reports: for buildings with significant cooling systems.

Environmental risk

• Environment Agency Flood Map for Planning: river and sea flood zones (1, 2, 3a, 3b).
• Environment Agency Surface Water Flood Map: surface water (pluvial) flood risk.
• Environment Agency Reservoir Inundation Map: areas at risk if a reservoir failed.
• Coal Authority records: historic and current coal mining hazards.
• British Geological Survey GeoSure: ground stability hazards (subsidence, swelling clay, landslide).
• Radon Atlas: indoor radon exposure risk.

Heritage and planning

• Historic England National Heritage List: every listed building, scheduled monument, and registered park or garden. Around 380,000 listed buildings in England.
• Cadw (Wales): equivalent register for Wales.
• Local authority conservation area maps: published by each council; not centrally aggregated.
• Local authority planning portals: planning applications, decisions, and history.
• MHCLG Planning Data Platform: central database of planning applications and policies.

Local authority

• Council tax bands from the VOA (England, Wales).
• Council tax rates from each local authority annually.
• Business rates from the VOA.
• Voter registration: from local authorities (used by lenders for credit checks).
• Refuse collection routes from each local authority.
• Highways data including USRNs and road classifications.

Demographics and socio-economic

• Office for National Statistics census: population, household composition, ethnicity, language, deprivation.
• English Indices of Deprivation (IMD): deprivation rank for every Lower Super Output Area (LSOA).
• Welsh Index of Multiple Deprivation: equivalent for Wales.
• NHS Health Indicators: GP registrations, life expectancy, hospital admissions by area.

Transport and amenities

• Department for Transport Walkability Index: walkability score by area.
• Public Transport Accessibility Level (PTAL): London Underground and overground accessibility.
• National Public Transport Access Nodes (NaPTAN): every public transport stop.
• Ofcom broadband and mobile coverage: connectivity by postcode.
• Schools and Ofsted ratings: every state and registered independent school.

Crime

• Police.uk crime data: monthly recorded crime by street, by force.

What is missing or hard to access

Despite the breadth, gaps remain:

• Building safety records for individual high-rise blocks: held by freeholders rather than in a central registry.
• EWS1 forms for cladding: held by individual building owners.
• HMO registers: each local authority publishes its own; no national aggregation.
• Rents data: ONS Index of Private Housing Rental Prices is at regional level, not per property.
• Service charge data for leasehold flats: held by freeholders and managing agents, not in a public registry.
• Estate management charge data for new build estates with private management companies.
• Repair history for individual properties.
