Accredited Official Statistics publication

Accredited Official Statistics are called National Statistics in the Statistics and Registration Service Act 2007.

The Biannual Civilian Personnel Report (BCPR) was introduced as a publication in April 2018 replacing the previously published Quarterly Civilian Personnel Report (QCPR). They comply with the standards of trustworthiness, quality and value in the Code of Practice for Statistics and should be labelled ‘Accredited Official Statistics’.

Accreditation can be broadly interpreted to mean that the statistics:

  • meet the needs of the identified users;

  • are well explained and readily accessible;

  • are produced according to sound methods; and

  • are managed impartially and objectively in the public interest.

Further information on the accreditation process can be found here: Accreditation explanation web page

Once statistics have been designated as Accredited Official Statistics it is a statutory requirement that the Code of Practice shall continue to be observed. Further details about how this report has been developed since its confirmation as an Accredited Official Statistic can be found in the Background Quality Report.

Our statistical practice is regulated by the Office for Statistics Regulation (OSR). OSR sets the standards of trustworthiness, quality and value in the Code of Practice for Statistics that all producers of official statistics should adhere to.

You are welcome to contact us directly with any comments about how we meet these standards. Alternatively, you can contact OSR by emailing regulation@statistics.gov.uk or via the OSR website

1. Main Points

MOD civilian personnel: Full Time Equivalent (FTE) and Headcount

At 1 October 2024, the MOD civilian personnel FTE was 60,549. This is a decrease of 906 (1.5%) compared with 1 October 2023.

At 1 October 2024, the MOD civilian personnel headcount was 62,631. This is a decrease of 911 (1.4%) compared with 1 October 2023.

MOD Civil Servants: MOD Civil Servants employed within MOD Main TLBs, Executive Agencies and Royal Fleet Auxiliary.

Figure 1 shows that at 1 October 2024 MOD Main Top Level Budgetary areas (TLBs) had the largest FTE share of 59.4%. MOD Executive Agencies accounted for 31.7%, Locally Engaged Civilians 6.2% and Royal Fleet Auxiliary’s share was the smallest at 2.7%.

Figure 1: Breakdown of MOD Civilian Personnel by Main Groups (FTE), 1 October 2024

Table 1 shows the FTE net change in civilian personnel between 1 October 2023 and 1 October 2024. MOD Main TLBs showed the highest percentage change with a decrease of 2.5 per cent, with Locally engaged civilians (LEC) showing an increase of 1.2 per cent.

Table 1: MOD Civilian Personnel by Main Groups (FTE)

1 October 2023 1 October 2024 Difference (number) Difference (% change)
MOD Main TLB 36,857 35,944 -913 -2.5%
MOD Main Executive Agencies 19,217 19,218 1 0.0%
Royal Fleet Auxiliary 1,675 1,636 -39 -2.3%
MOD Civil Servants 57,749 56,799 -951 -1.6%
Locally engaged civilians 3,706 3,750 44 1.2%
MOD Total 61,455 60,549 -906 -1.5%

MOD Main Top Level Budgetary areas (TLBs) are the major organisational groupings of the Department directly responsible for the planning, management and delivery of departmental capability. These are Navy Command, Army TLB, HQ Air Command, Head Office, UK Strategic Command, Defence Infrastructure Organisation and Defence Nuclear Organisation. Please see glossary for further information.

MOD Executive Agencies are self accounting units that have greater freedom than other government departments in managing their own financial and management activities. These are UK Hydrographic Office, Defence Science & Technology Laboratory, Submarine Delivery Agency, and Defence Equipment & Support. Please see glossary for further information.

Royal Fleet Auxiliary are a civilian-manned fleet, owned by the MOD, which supports Royal Navy ships around the world, supplying warships with fuel, ammunition and supplies.

Locally Engaged Civilians are employees are recruited overseas exclusively for employment in support of the UK Armed Forces. LECs are also employed on terms and conditions analogously with local employment law and market forces, and not those of the UK.

Figure 2 demonstrates an overall trend of increasing civilian workforce (FTE) from 1 April 2019 to 1 January 2024. MOD civilian strength peaked at 1 January 2024 and has since been steadily decreasing to 1 October 2024, returning to levels similar to 1 April 2023.

On 29 July 2024, the Chancellor announced in the public sector spending audit that Departments should make value for money decisions and drive efficiencies. Defence is working to ensure its Civil Service workforce remains affordable and targeted at delivering the Department’s priorities. The reduction in MOD Civil Service strength since January 2024 reflects the Department’s contribution to the previous administration’s headcount cap which has now been removed.

3. Civilian Personnel by Grade

Figure 3 shows the breakdown by grades of personnel (FTE) in MOD Main TLBs. At 1 October 2024, Senior and Higher Executive Officers accounted for the highest proportion at 34.8%, followed by Administrative Officers and Assistants at 29.4%. The remaining proportions were shared between Grade 6 & 7 personnel (9.6%), Executive Officers (17.6%), Industrial personnel (7.6%) and the smallest section: SCS at 1.0%.

The proportion of personnel in a MOD Main TLB who were classified as non-industrial has slowly increased since 1 April 2019. The proportion has ranged from 88.3% at 1 April 2019 to 92.4% as at 1 October 2024.

Non-industrial personnel undertake work such as administration, analysis, policy, procurement, finance, medicine, dental care, teaching, policing, science and engineering. Non-industrial grades are shown in terms of Civil Service grade structure and based on substantive grade. 

Industrial personnel are employed primarily in a trade, craft or other manual labour occupations. This covers a wide range of work done by industrial technicians, air freight handlers, storekeepers, vergers and drivers etc.

The two most common reasons for leaving of civilian personnel in a MOD Main Top Level Budgetary areas (TLBs) from 1 October 2023 to 30 September 2024 were resignation and retirement, accounting for 35.8% and 27.7% respectively (Figure 4).

Figure 4: Outflow by Reason of MOD Main TLB Personnel, 1 October 2023 to 30 September 2024

Figure 5 shows the overall net flow of civilian personnel in MOD Main Top Level Budgetary areas (TLBs) per 12 months. The overall net flow trends were negative from 1 April 2022 onwards, changing to a positive net flow from 1 July 2023. Since 1 July 2024, the net flow has reverted to a negative trend, caused by the Departments contribution to the previous administration’s headcount cap, which has now been removed.

For the 12 months from 1 October 2023 to 30 September 2024, the outflow from MOD Main TLBs was 4,163 and the intake 3,171; resulting in 992 net flow decrease.

6.1 Rounding

Tables and Charts within this document

Percentages and related change in percentage points across time periods are calculated from unrounded data and rounded to one decimal place. Totals and sub-totals are rounded separately and so may not equal the sums of their rounded parts. This also applies to civilian personnel data expressed in terms of Full-Time Equivalents (FTE).

Excel tables accompanying this publication

An updated MOD Disclosure Control and Rounding policy has been published on GOV.UK and we have applied this policy to the statistics on Civilian personnel in the accompanying Excel tables. The policy is available here.

Disclosure control will still be applied to statistical or numeric information to safeguard the confidentiality of individuals.  ‘Disclosure control’ refers to the efforts made to reduce the risk of disclosure, such as applying statistical methods to protect ‘personally identifiable information’ (PII) in aggregated data tables. These safeguards can take many forms (e.g. data suppression, rounding, recoding etc.).

6.2 Revisions

Occasionally errors can occur in statistical processes; procedures are constantly reviewed to minimise this risk. Should a significant error be found the publication on the website will be updated and an errata slip published documenting the revision.
