Aipedia: Data protection consultants
Consultants can use AI to search, review and redact material for subject access requests, but they remain responsible for what is disclosed and what is missed. Errors in either direction can lead to complaints, ICO enquiries and claims from the client.
Part of: AI in Data protection consultants
In short
Outsourced DPOs and consultants often run subject access requests for clients, and AI tools can help search mailboxes, classify documents and suggest redactions. Since 5 February 2026 the DUAA has confirmed that searches need only be reasonable and proportionate, and section 76 on time limits is in force. AI can make large requests manageable, but it can also redact too little, releasing other people's data, or too much, withholding what the requester is entitled to. Either mistake can generate complaints and a claim by the client against the consultant. PI usually responds, subject to the wording.
Subject access requests linked to employment disputes or complaints can involve tens of thousands of emails, chat messages and documents. Consultants and outsourced DPOs who handle these for clients may use AI-assisted review platforms to deduplicate material, identify documents that relate to the requester, flag third-party personal data and propose redactions. Some also use generative AI to draft the covering response and the explanation of exemptions relied on.
The efficiency gain is real. So is the risk: a classifier that misreads a nickname, a redaction model that misses a name in an image or attachment, or a summary that misdescribes what was withheld.
Background on the rights involved is in data subject rights.
Illustrative scenario: an outsourced DPO handles a request from a former employee in dispute with a client. AI-assisted review is used to find and redact documents. The tool misses a colleague's health information in an attached spreadsheet, which is disclosed. At the same time, a set of messages using the requester's initials is not picked up. The colleague complains about the disclosure, the requester complains about missing material, and the client asks the DPO to cover its costs of dealing with both complaints and the ICO's enquiries.
The "reasonable and proportionate" test helps on searches, but it does not excuse an unreasonable search design or a failure to check what the tool produced. Nor does it apply to redaction errors, where the issue is what was released rather than how hard anyone looked.
A client's claim that its consultant handled a request negligently is usually within PI cover, subject to the terms. Where the error is a disclosure of personal data, the claim may also have a data breach character, and PI and cyber policies treat that differently; see GDPR and data breach cover within PI. Data subjects may also bring compensation claims; see data protection civil claims and cover.
Two practical points affect cover. If you become aware of a disclosure error, it may be a circumstance to notify to your PI insurer as well as a breach for the client to assess. And if the review platform you use suffers its own security incident, a cyber policy may be the first place to look.
Apex arranges PI for data protection consultants and outsourced DPOs. A broker can review how your policy treats DSAR handling and disclosure errors; see the data protection consultants' AI hub.
Nothing in the UK GDPR prevents it, but the tool must be used under proper processor terms and the controller remains responsible for the result. A person should check the search design, the relevance decisions and every redaction before disclosure.
The DUAA confirms that a controller need only carry out reasonable and proportionate searches for a requester's personal data. Recording how the search was designed and why it was proportionate is the best evidence that the test was met.
Indirectly, yes. Since 19 June 2026 controllers must acknowledge data protection complaints within 30 days. A requester unhappy with a response is likely to complain to the controller first, so the request process and the complaints process should be linked.
The controller is answerable to the ICO and to the affected person. If a consultant ran the process, the client may claim against the consultant for negligence. PI usually responds to that claim, subject to the wording and any data breach provisions.
