A case is opened when it is received from an external source or an issue is identified by a member of OSR. A case is closed when the issue has been considered and any necessary action has been taken.

The median and mean number of days taken to close a case are reported. This measure is based on calendar days (not working days) so includes weekends and bank holidays. The median is considered the best headline measure as it reflects the typical experience. When calculating time taken to close a case, cases that were closed on the same day that they were received or identified have a one day response time, rather than 0.

Data provided in the table are provisional figures which may be revised in future quarters or as part of the annual review. For example, there will be occasions where a case is closed after the provisional data are reported.

As of the time of reporting these data (30 July 2026) there are 2 cases from 2025/26 still open. These cases are included in the total number of cases, but not in the figures for median or mean time to close a case. The median and mean time to close a case may increase when the cases which remain open are included. Where needed, revised data will be provided in the following quarter or as part of the annual review.

Quarterly data will be published on the last Thursday of the month following the relevant quarter. The next update will be at 11am on 29 September 2026.

The Annual review of casework 2025/26 was published on 24 June 2026, providing details of casework during 2025/26 and the Election period 2026. You can see details of all cases we have considered so far in 2026/27 in the Casework issues log.
