What this law does
UK GDPR Article 15 gives a data subject the right to obtain from the controller confirmation of whether their personal data are being processed and, where they are, access to the data. Article 15(1A), inserted by the Data (Use and Access) Act 2025, limits what a data subject is entitled to under Article 15(1) to what the controller can provide based on a reasonable and proportionate search.
Article 16 gives a data subject the right to have the controller rectify inaccurate personal data concerning them without undue delay. Article 17 gives a data subject the right to have the controller erase their personal data without undue delay where the data are no longer necessary for the purposes for which they were collected or otherwise processed, among other grounds.
Article 17(3) disapplies the erasure right to the extent that processing is necessary for exercising the right of freedom of expression and information, among other listed cases. Article 18 gives a data subject the right to obtain restriction of processing where the accuracy of the personal data is contested by the data subject, among other cases.
Article 20 gives a data subject the right to receive the personal data they have provided to a controller in a structured, commonly used and machine-readable format, where the processing rests on consent or a contract and is carried out by automated means. Article 21(1) lets a data subject object, on grounds relating to their particular situation, to processing based on point (e), (ea) or (f) of Article 6(1), and the controller must then stop unless it demonstrates compelling legitimate grounds.
Article 21 also gives a data subject the right to object at any time to processing of their personal data for direct marketing, after which the personal data may no longer be processed for that purpose. Article 12A defines the applicable time period under Article 12 as the period of one month beginning with the relevant time. A controller may extend the applicable time period under Article 12A by two further months by giving notice, where the complexity or number of requests makes it necessary.
Article 12A was inserted into the UK GDPR with effect from . Under Article 12(5) a controller may charge a reasonable fee or refuse to act where a request is manifestly unfounded or excessive, and bears the burden of demonstrating that. Section 164A of the Data Protection Act 2018 requires a controller that receives a data subject's complaint to acknowledge it within 30 days and then to respond to it without undue delay.
Section 164A was inserted by the Data (Use and Access) Act 2025 and has been in force in full since . Article 4(1)(7) defines a controller as the natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data.
