- Wales charges: Welsh Government, council tax levels.
- Scotland charges and dwellings: Scottish Government council tax datasets; charges exclude Scottish Water.
The build pipeline, including every source URL and the validation it runs, is documented in the repository. Contains public sector information licensed under the Open Government Licence v3.0. We do not alter any source figure; the only derived fields are the band charges computed from Band D and the most common band.
