We have updated all our Local Authority map bases in line with changes that have come into effect on 1 April 2023. As far as we can see, we have actually beaten the Government itself in issuing the new boundary data!

The changes are as follows:
Cumberland – formerly Allerdale, Carlisle, Copeland
Westmorland and Furness – formerly Barrow-in-Furness, Eden, South Lakeland
North Yorkshire – formerly Craven, Hambleton, Harrogate, Richmondshire, Ryedale, Scarborough, Selby
Somerset – formerly Mendip, Sedgemoor, Somerset West and Taunton, South Somerset
We sell two vector art packages for the Local Authorities: one juxtaposed with postcodes and the other without. Both are bundled with a premium pass for the Dynamic Mapping Suite, which contains interactive online maps of the new Local Authorities with advanced search. Users can colour and caption the Local Authorities online with their own data.
If you have data you want to feed to the old Local Authorities, before the April 2023 mergers in Cumbria, Yorkshire and Somerset, we have included an older version in both the download package and in the spreadsheets to polygons system in the Dynamic Mapping Suite. This is handy if, for example, your data relates to the 2021 census.
