Access To Information

The domestic legal framework which governs an individual’s general rights to request information held by public sector bodies is found within the Data Protection Act 2018, the UK General Data Protection Regulation, the Freedom of Information Act 2000 and the Environmental Information Regulations (EIR).  MI5 is not subject to the Freedom of Information Act or the UK General Data Protection Regulation however.  Data access rights which do apply to MI5 can be found within Part 4 of the Data Protection Act and the Environmental Information Regulations.

Data Protection Act 2018 (DPA)

The DPA gives individuals a right of access to personal data concerning them. Requests for access to personal data may be made to MI5 under section 94 of the DPA. Such requests are known as “subject access requests” or “SARs”.

If you would like to make a Subject Access Request, please send a cheque for £10 made payable to SAR Account to:

The Data Controller

PO Box 3255

London

SW1P 1AE.

You must also provide a copy of an official means of identification (eg: a passport, driving licence etc) as well as a current utility bill or bank statement less than three months old bearing your name and address.

Section 110 of the DPA contains certain exemptions to the right of access in section 94 where exemption is required for the purpose of safeguarding national security. MI5 considers on a case by case basis whether it is necessary to rely on the national security exemption. Where the national security exemption is relied upon, a certificate signed by a Cabinet Minister, the Attorney General or the Advocate General for Scotland constitutes conclusive evidence that the exemption is required, subject to a right to appeal against the certificate in the First-tier Tribunal.

Individuals who are dissatisfied with MI5’s response to a SAR have a right to complain to the Information Commissioner. For more information about your rights, please refer to the ICO website.

Please be aware that written correspondence posted in the UK may take up to a week to reach us.

Historic Enquiries

If you would like to make an historic enquiry about a family member's potential previous employment with MI5, please provide a copy of the death certificate - this can be a copy or the original and can be returned upon request.

Freedom of Information Act 2000 (FOIA)

FOIA allows members of the public to request access to information held by public authorities. MI5, along with the other security and intelligence agencies, is not subject to FOIA.

For further information on FOIA, please refer to the ICO website.

Environmental Information Regulations (EIR)

The Environmental Information Regulations allow the public to request access to information about the activities of public authorities which relate to the environment. MI5 is subject to the Regulations, although exemptions can be used when necessary (to protect national security, for example). We will consider on a case by case basis whether an exemption applies. Please make any Environmental Information Regulation requests through our contact form.
