Unitary Councils
There are going to be more of these, so I thought I'd keep track of what I did for the Surrey ones.
-
Go to https://github.com/mysociety/uk_local_authority_names_and_codes/ and suggest some new reg codes. They should be three capital letters, and be unique. example issue

Make the organisation, organisation geography and elected role. There is a command for this: every_election/apps/organisations/management/commands/create_unitary_authority.py
python manage.py create_unitary_authority \
--official-name 'West Surrey Council' \
--common-name 'West Surrey' \
--identifier WSY \
--constituent-councils E07000209 E07000212 E07000213 E07000214 E07000216 E07000217 \
--slug west-surrey \
--start-date 2026-07-01- Make the divisions
It seems sensible to have a record of how these were made. I did this with a jupyter notebook, so I've copied the relevant bits here. The formatting is horrible, so might be easier to click edit and copy the source.
Somerset
Includes making divisions from the old county divisions, but also a couple of the new divisions had to be made from district wards.
