Every figure in a Buyer Folio derives from a named public dataset. This page records the licence each one is used under and the attribution it requires. If you believe an attribution here is incomplete, write to team@settleiq.co.uk and it will be corrected.

Open Government Licence v3.0

The majority of the datasets below are public sector information licensed under the Open Government Licence v3.0. Use of this information does not imply endorsement by the licensor.

HM Land Registry

Contains HM Land Registry data © Crown copyright and database right 2026. This data is licensed under the Open Government Licence v3.0. Price Paid Data tracks residential property sales in England and Wales lodged for registration; it does not include commercial transactions, transfers not for value, or sales that have not yet completed registration.

Office for National Statistics

Contains OS data © Crown copyright and database right. Contains Royal Mail data © Royal Mail copyright and database right. Source: Office for National Statistics licensed under the Open Government Licence v3.0.

Environment Agency

National Flood Risk Assessment data © Environment Agency copyright, licensed under the Open Government Licence v3.0. Flood risk classifications are indicative and are drawn from the published NaFRA dataset rather than a site-specific survey; they should not be read as a substitute for a conveyancer's own flood searches.

Historic England

National Heritage List for England data © Historic England, licensed under the Open Government Licence v3.0. Listing entries are reproduced as published; the definitive record for any specific listing remains the one held by Historic England.

Department for Education / Ofsted

School record and inspection-grade data © Crown copyright and database right (Department for Education), and © Crown copyright (Ofsted), licensed under the Open Government Licence v3.0. Inspection grades reflect the most recent published report at the stated extraction date and may have changed since.

Ofcom

Connected Nations coverage data © Ofcom, licensed under the Open Government Licence v3.0. [NEEDS CONFIRMATION] Ofcom publishes this data at postcode/premises resolution through its own reporting tools rather than as a single bulk open-data file in the way HMLR or ONS data is published — confirm the exact extraction method used and that it falls within Ofcom's permitted reuse terms for the resolution and format actually consumed here.

British Geological Survey / UK Health Security Agency

[NEEDS CONFIRMATION] Radon potential classification data is produced by the British Geological Survey in partnership with UKHSA. Unlike the other Crown-copyright datasets on this page, BGS has historically applied its own licence terms to some geological datasets rather than the standard Open Government Licence — confirm the specific licence BGS/UKHSA radon data is published under before relying on the general OGL statement above for this dataset, and add the correct attribution wording here once confirmed.

OpenStreetMap

Amenity and context data © OpenStreetMap contributors, available under the Open Database Licence. Any derived database produced from it is made available under the same terms.

Other Crown copyright sources

The Council Tax Valuation List (Valuation Office Agency), Energy Performance of Buildings Register and planning/conservation-area data (Ministry of Housing, Communities and Local Government), Indices of Multiple Deprivation (MHCLG), and National Public Transport Access Nodes (Department for Transport) are each © Crown copyright and database right, licensed under the Open Government Licence v3.0, with no additional restriction beyond the standard OGL attribution above.

Currency and error

Public datasets are refreshed on their publishers' own schedules and are not error-free. A Buyer Folio states the extraction date for each dataset it uses. Where a folio's conclusion is sensitive to a value that may be stale or disputed, the folio says so in the section that relies on it rather than in a general disclaimer.
