We sent Freedom of Information (FoI) requests to a total of 390 local authorities in all four UK nations. This covered all the 375 principal local authorities in England, Northern Ireland, Scotland and Wales. We included city, borough, district and county councils. The list of councils we purchased from a third party also included a handful of town councils to which we also sent FoI requests. See Annex 1 on page 30 of the report for the full list of councils we contacted.
However, as there are an estimated 10,000 smaller town and parish councils in the UK, we did not have the capacity to contact them all.
If your council is not listed on our database, do feel free to send them your own FoI request which you can download here. In addition, you can get a sense of what is going on in your area by searching for your county in the database.
