The Civil Service embraces diversity and promotes equal opportunities. As such, we run a Disability Confident Scheme (DCS) for candidates with disabilities who meet the minimum selection criteria.

There may be occasions where it is not practicable or appropriate to interview all DCS candidates that meet the minimum criteria for the job. For example, in certain recruitment situations such as a high volume of applications, seasonal demand, or peak periods, the employer may wish to limit the overall number of interviews offered to both DCS and non-DCS applicants.

As a result of the changes to the UK immigration rules which came into effect on 1 January 2021, the Ministry of Defence will only offer sponsorship for a skilled worker visa under the points-based system, where a role has been deemed to be business critical. This role does not meet that category, and we will not sponsor a visa. It is therefore NOT open to applications from those who will require sponsorship under the points-based system.
Should you apply for this role and be found to require sponsorship, your application will be rejected and any provisional offer of employment withdrawn.

The Ministry of Defence requires all candidates who are successful at interview to declare any outside interests. These declarations will be discussed with successful candidates following the interview process and before a formal offer of employment is made, as some outside interests may not be compatible with MOD civilian roles. This will not, in the majority of cases, prevent employment in MOD, but it is a measure that must be taken to ensure that appropriate mitigations can be put in place to manage any potential, perceived or actual conflicts of interest from the first day of employment.

The Ministry of Defence adopts a zero-tolerance approach to unacceptable behaviours, which includes bullying, harassment, sexual harassment, discrimination, and victimisation. You will not be eligible and will not be considered for this post if you have been dismissed from a role for such unacceptable behaviours within the last five years. This will also apply if you resign or otherwise leave a role but, because of an adverse decision, would have been dismissed for gross misconduct had you continued in that employment. Pre-employment checks will be carried out.
