UK Land Data API - Parcels, Planning, Titles, Owners

parcel-id

Charged once for each parcel identifier returned by a search when full records were not asked for. Useful when you want to filter a large result set before spending lookups on it. Searches that match nothing are not charged.

planning-application

Charged once for each planning application: the authority's GSS code and its own reference, the site address, the description of the proposal, the number of residential units identified, the derived application types, the authority's own status and the provider's derived status side by side, the decision and its date, the applicant and agent, the link to the authority's page, and the application's location. Applications the provider has no record for are not charged.

planning-reference

Charged once for each planning application reference returned by a geometry search when full records were not asked for: the planning authority GSS code, the authority's reference, and the composite ID that reads the full application. Searches that match nothing are not charged.

title-record

Charged once for each HM Land Registry title: the title number, whether it is freehold or leasehold, its registered addresses, the UPRNs on it, the registered proprietors with their company numbers and countries, the ultimate owner behind any holding company, the date ownership last changed, and the registered lease term where there is one. Title numbers the provider has no record for are not charged.

property-record

Charged once for each property: its UPRN and full address, the property type, its current state from in use through to demolished, the Ordnance Survey classification code, the planning use class, the building's highest point and roof height in metres with an estimated floor count, and the current and potential EPC ratings with the certified floor area. UPRNs the provider has no record for are not charged.

site-feature

Charged once for each site designation record: a land availability assessment, development constraint, development opportunity, Homes England site, local plan policy, power asset, strategic industrial location or renewable energy site. Carries the feature identifier, its type and name, every attribute the collection publishes as key and value pairs, the total area in hectares, and a centre point, with the full ring on request. Identifiers the provider has no record for are not charged.

region-record

Charged once for each local authority in the region catalogue: its GSS code and its name. This is the list that tells you which codes a parcel search will accept, so it is priced low enough to run before a real search rather than guessed at.

account-record

Charged once for the account status check: whether the key is recognised and whether the subscription behind it is active, expired or blocked. One row, priced as low as the platform allows, so checking a key before a large run costs almost nothing.
