Our scores are built from public data, much of it under Crown copyright or the Open Government Licence. Those licences ask for credit wherever the data is shown. So does Check That Field.

What to show

Wherever you show data from the API, show:
  1. Every line of the answer’s attribution array, word for word, near the data.
  2. A credit to Check That Field, with a link to checkthatfield.com.
  3. A short note that the scores are an automated indicator from published data, not planning or legal advice.
“Near the data” means on the same page or screen, where a reader can find it without leaving: under a map or table, or in a footer or info panel beside it.
Take the lines from each answer rather than copying them into your code. If a licence changes, the answer changes with it.

The attribution array

Every answer from /v1/scores and /v1/fields/{field_id} has an attribution array of strings. Today it holds these lines:
This information is subject to Crown copyright and database rights [year] and is reproduced with the permission of HM Land Registry. The polygons (including the associated geometry, namely x, y co-ordinates) are subject to Crown copyright and database rights [year] Ordnance Survey AC0000851063.
Contains OS data © Crown copyright and database right. Contains Royal Mail data © Royal Mail copyright and database right.
Contains Environment Agency, Natural England and Office for National Statistics data, licensed under the Open Government Licence v3.0.
Planning applications: the councils’ public planning registers; each links to the council’s page, which is the official record.
The first line is the statement HM Land Registry asks for with its INSPIRE index polygons, which give each field its outline. Show it whenever you show our fields, outlined or not: the scores are worked out field by field from those outlines. The planning applications line comes only when the answer includes applications. If you call /v1/scores with applications=false, it is left out, and you needn’t show it.
Show the lines as given. Don’t shorten, merge or reword them.

Planning applications

The applications in our answers come from the councils’ public planning registers. We pass on the register’s facts only: the reference, address, proposal, type, homes proposed, status, decision, dates and where we placed it.
  • The council’s page is the official record. Each application’s url links to it. Link to it wherever you show an application, so readers can check the details and see the documents there.
  • No documents, no names. We don’t pass on plans, letters or other documents, or the names of applicants, agents or anyone who commented. Don’t add them from elsewhere beside our data.
  • Say how it was placed. located_by says how we put an application on the map: published (the council’s own location), postcode (the postcode in its address) or address (the words of its address). Positions placed by postcode or address are approximate.

The widget does this for you

The widget shows the attribution and a link to the full report itself. You don’t need to add anything around it.
