Nationality, visas and vetting: For security reasons this role is open to sole UK nationals only. A ‘sole UK national’ refers to an individual who holds citizenship solely in the UK, without dual citizenship or nationality from another country. We’re unable to offer visa sponsorship. This role requires you to have lived in the UK for the last 10 years and obtain Developed Vetting (DV) security clearance. Clearance must be obtained without any caveats that prevent you from carrying out the role you have been recruited for. If it isn’t obtained or is obtained but with caveats that prevent you from carrying out the role, any conditional offer made to you will be withdrawn. Obtaining DV security clearance can be a lengthy process. You’ll join us once Security Check (SC) clearance is obtained, and then the more enhanced DV checks will continue after you’ve started your employment. If SC clearance isn’t obtained within 12 months, we reserve the right to withdraw any conditional offer made.
