Data Subject Access Requests – what are people entitled to?

February 2025

I’m often asked what’s in scope when responding the Right of Access – aka Data Subject Access Requests (DSAR/SAR). What are organisations obliged to provide, and what can they legitimately exclude? I’ve taken a look at some questions which routinely come up. But first a quick summary of what the law says…

The Right of Access is a fundamental right under data protection legislation in the UK and EU. There are similar rights in other jurisdictions, but I’m focusing here on the right under UK GDPR and the Data Protection Act (DPA 2018).

The law gives people the right to receive and copy of their personal data, and other supplementary information from any organisation acting as a controller. Controller or processor – what are we?

Personal data is any information which could directly or indirectly identify the requestee. To give some examples, this could include images, voice and video recordings, demographic information, profiles, order history, marketing preferences, HR records, performance reviews, opinions expressed about the requestee, other personal identifiers … and the list goes on.

Now, on to the FAQs…

Q: Do we need to provide information the requestee already has, or is obvious to them?

The short answer is, yes. Based on UK case law, organisations can’t refuse to disclose information on the grounds personal data is already known to the individual. (Case: Lttihadieh v 5-11 Cheyne Gardens, 2017). However, it wouldn’t need to be included if the person has made it clear they don’t want this information. You can always ask them.

Q: Are they entitled to full documents?

It isn’t a right to documentation. Just because someone’s name appears in a report, spreadsheet, meeting notes or any other document doesn’t mean they’re entitled to the whole document, if the rest doesn’t relate to them. It may prove easier and relevant to provide full documents, but you would be justified in not doing so. You can extract the necessary information, or redact the irrelevant information. But remember what you provide must be meaningful and have context.

Q: Are they entitled to the full content of email correspondence?

Linked to the question above, people are only entitled to a copy of their personal data. So just because their email address or email signature appears in an email (or email chain) doesn’t make this their personal data. For example, routine business as usual emails, where the content is solely about business related matters will not be the individual’s personal data. It can be really helpful to explain this from the start.

Q: Are handwritten notes in scope?

Personal data which is not part (or intended to be part) of a structured filing system is not in scope. For example handwritten notes in a personal notepad where there’s no intention to formally file these notes would not need to be included. However, if for example, employees write notes in ‘day books’ which are intended to be kept as a record of conversations, these would be in scope.

Q: How much effort is required?

Organisations are expected to make all reasonable efforts to search, identify and retrieve all the personal data being requested. The ICO would expect systems to be well-designed and maintained so information can be efficiently located (including carrying out searches) and extracted. The right of access is not new. It was around long before GDPR came into force in 2018, so organisations would be expected to be well prepared to handle requests.

Q: Can we refuse to comply with a request?

Sometimes it may seem obvious the requestee has an ulterior motive for submitting a DSAR. In general, an individual’s motives shouldn’t affect their right to obtain a copy of their personal data, or the organisation’s duty to respond. Organisations can however refuse to comply with a request, either partially or fully, where they judge it to be manifestly unfounded or manifestly excessive.

A request might be considered manifestly unfounded if, for example, the individual…

 has no real intention of exercising their right
offers to withdraw their request in return for some kind of benefit
explicitly states they want to cause disruption
makes unsubstantiated accusations or allegations
is targeting a specific employee due to a grudge
sends regular and targeted requests as part of a concerted campaign

A request might be considered manifestly excessive if it’s clearly or obviously unreasonable or would involve disproportionate effort. In assessing whether it would involve disproportionate effort, you should consider the following factors:

the nature of the requested information;
the context of the request, and the relationship between you and the individual;
whether a refusal to provide the information or even acknowledge if you hold it may cause substantive damage to the individual;
your available resources;
whether the request largely repeats previous requests and a reasonable interval hasn’t elapsed; or
whether it overlaps with other requests (although if it relates to a completely separate set of information it is unlikely to be excessive).

If you rely on either of these grounds, be sure to document your decision, the rationale behind it and explain this to the individual.

To give an example, quite a few years ago I worked on a request from a disgruntled former employee where, among everything else, they asked for all CCTV footage of them. The business operated CCTV which captured employees as they entered and exited the main office. We asked the individual if there were specific dates and times they were interested in. They responding just reiterating the request for all CCTV footage. I think understandably we judged this to be an manifestly excessive request, requiring disproportionate effort and that it would not cause any damage to the individual not to receive this.

Q: What can be excluded or redacted?

Once all the information relating to the individual has been retrieved, the data collated often includes information which doesn’t need to be disclosed. There may be justifiable grounds for excluding information or redacting documents, emails, video recordings and so on.

Information relating to others: the person making the request has a right to receive a copy of their personal data, they’re not entitled to personal data about other people. The DPA 2018 confirms you do not need to include certain information if it means disclosing information which identifies someone else, unless the other person has given their consent or it’s reasonable to disclose without the other person’s consent.

Confidential information: A duty of confidence may arise when another individual has genuinely shared ‘confidential’ information with the expectation it remains confidential. Confidentiality cannot be automatically assumed and needs to be assessed on a case-by-case basis. Other information which may also be considered confidential includes, but is not limited to; trade secrets, information made confidential under another law, internal costs or commercial rates, intellectual property and information covered as part of a non-disclosure agreement

Other exemptions: The DPA 2018 provides a number of further exemptions which may apply depending on the nature of your business and the context of the specific request. These don’t always apply in the same way. Sometimes you might be obliged to rely on an exemption (i.e. it would break another law), other times it will be a choice. Commonly used exemptions include; legal professional privilege, crime and taxation, management information, research and statistics, confidential references and journalism.

The ICO says exemptions should not be routinely relied upon or applied in a blanket fashion. And remember, you may be required to demonstrate how an exemption applies and your rationale for relying on it. The ICO has published guidance on exemptions and how they apply.

These are just some questions I get asked and I’m afraid to say there are plenty more. Responding to DSARs can be very time-consuming, with nuanced considerations and can feel a minefield if you don’t receive many requests or out of the blue receive your first one. Our DSAR Guide provides more information about how to prepare and fulfil requests. Also see the ICO’s detailed Right of Access Guidance.
