These results are provided by the Press Association (PA). Numbers for change in seats are calculated against the state of the council or parliament just before this election. Other organisations calculate using the previous election, and this can lead to discrepancies. In Wales, the electoral system is sufficently different to previous elections that comparison is not given.

Other outlets may also announce individual ward councillor results as they become known, while PA release results for each council only when its full count is complete. PA collates results only for elections that were due in this electoral cycle, meaning there may be council byelection results in other parts of the country that are not included. There are frequent changes in ward boundaries, sometimes accompanied by changes in the number of councillors overall. “Shadow elections” were also held for two new unitary authorities due to be created in Surrey in 2027.
