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 (25 April 2024) there are 13 cases from quarter 4 2023/24 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 25 July 2024 which will cover the first quarter of 2024/25.

The 2023/24 annual casework review will be published in September 2024 providing more details of casework during 2023/24. You can see details of all cases we have considered in 2023/24 and so far in 2024/25 in the Casework issues log.

The management information provided on this page has been produced in the interests of demonstrating transparency. In producing the report, we have taken a proportionate approach to applying the pillars of the Code of Practice for Statistics – Trustworthiness, Quality and Value.

Trustworthiness – Confidence in the people and organisations that produce statistics and data

The data published on this page is produced with the public interest in mind. The report was compiled by the Office for Statistics Regulation, which made all decisions on what to include in the report. The report protects the confidentiality of those who made enquiries to the Authority.

Updates to the data will be made quarterly on the last Thursday of the month following the end of the quarter (i.e. the last Thursday in July, October, January and April).

Quality – data and methods that produce assured statistics 

The review is based on management information held to support the Authority assess its performance and track key issues. Quality assurance of the final version of all figures quoted in the report was undertaken by an analyst within the Authority who did not work on the compilation of the data.

The data comes from the Authority’s casework management system, which is subject to internal audit review and assurance.

Value – statistics that support society’s needs for information

The report is being published in the interests of providing greater transparency on the Authority’s casework. Through publication on the Office for Statistics Regulation website, it is being made available to all those with an interest in the Office for Statistics Regulation’s process.

Please send any feedback on these data to to enable the Authority to understand the value of this information and develop it in ways that will support user needs in future.
