I have been carrying out personal research into CMS used by local authorities in the UK for over 3 years. I completed my latest review in October 2022 and you can view the results on Airtable. In the past I have tried to check each site individually, but it is very labour intensive and liable to error. This year I have used WhatCMS to do the heavy lifting and fill in the gaps with a manual review and by contacting councils directly.
There hasn’t been a great deal of change in CMS used by councils over the last year. Jadu and Drupal continue to lead the pack with a number of new additions for each of these CMS. On the Drupal front increased council take up is linked to the growing popularity of LocalGov Drupal.
My next task is to update the various maps that I have created to present local government use of CMS in the UK. These can be found on my blog.
I hope you will find this research useful. If you spot any errors or want to report any changes please get in contact.
