A security pass is required by everyone working on the parliamentary estate, requiring access to the parliamentary network or being given access to sensitive parliamentary information.
Upon appointment to a Member’s office, a new member of staff will be required to comply with the Baseline Personnel Security Standard (BPSS) and undergo a Counter Terrorist Check (CTC).
You can find full information about security vetting and the Members’ Staff Security Clearance and Pre-Employment Check Questionnaire here: https://intranet.parliament.uk/security/personal-security-vetting-and-passes/security-forms/
Applications for security clearance are now made online only. Paper forms will no longer be accepted. You can read more about this here: https://intranet.parliament.uk/security/personal-security-vetting-and-passes/security-vetting-and-pass-programme-pilot/
