As a result of the changes to the UK immigration rules which came in to 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role and be found to require sponsorship, your application will be rejected and any provisional offer of employment withdrawn.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.
