Further to my previous blog posts on CMS in English Local Authorities and CMS used by Scottish Local Authorities I have now created a map showing CMS used in the United Kingdom. Unfortunately I had to start from scratch again so this took quite a long time and was a bit laborious, but I hope it will prove useful. I have ordered the map by web content management system. I have listed selected the most used CMS and then added a catch all for the remaining CMS. There are just so many different CMS that its impossible to plot them all as separate sections on Google maps. I only found seven local authorities where I couldn’t detect the CMS that they use. If anyone can help with any of these please contact me via Twitter. Equally if you find any errors please do let me know.
Local authority boundaries used in the map were sourced from the Office for National Statistics licensed under Open Government Licence v.3.0. Many thanks to the ONS for sharing such a useful map.
I’m still planning to create a separate map for CMS used by Welsh local authorities as I promised I’d do this in a previous blog post. Then I think I’ll move onto a new topic and I have some really good ideas on what to focus my personal research, that I think will be very interesting to work on. Watch this space!

Hi Colin. This is really interesting, thank you for pulling this together! Is there another version of this that takes account of two-tier councils? For example, there will be a double digit number of county councils that sit above the district and borough councils indicated in some areas, and they aren’t reflected above.
Hi Rich, county and unitary councils are included as far as I am aware. Can you identify any that are missing? The map of CMS in English Local Authorities might help as this is organed by council type – https://colinstenning.com/2021/11/10/cms-used-by-local-authorities/
