You can apply for any job in the Civil Service as long as you are a UK national or have dual nationality with one part being British. In addition, about 75% of Civil Service posts are open to Commonwealth citizens and nationals of any of the member states of the European Economic Area (EEA). The remainder, which require special allegiance to the state, are reserved for UK nationals.
The “Civil Service Nationality Rules: Guidance on Checking Eligibility” has been extensively updated. It is intended to assist departments and agencies to discharge effectively their responsibilities on nationality matters related to Civil Service recruitment. For ease of reference, specific aspects of nationality have been addressed in separate annexes to the guidance.
