In short: a recruitment agency is normally a controller for its candidate database. It has to give privacy information to the people it sources, not just those who apply, and it needs a lawful condition before it touches health or criminal record data. Whether a DPO is mandatory depends on scale (plenty of agencies appoint one anyway, because clients ask for a named contact).
Engage Compliance acts as the named DPO for recruitment agencies, notified to the supervisory authority, with the same expert on your account throughout.
Key takeaways
- The ICO’s draft recruitment guidance says recruiters are likely to be controllers in most circumstances, so an agency cannot treat candidate data as its client’s problem.
- Candidates you find through a search, rather than through an application, still have to receive your privacy information, at the latest within one month (UK GDPR Article 14(3)).
- Criminal record data needs a Schedule 1 condition under section 10(5) of the Data Protection Act 2018, and health data or data revealing ethnic origin needs an Article 9 condition.
- Automated CV screening and ranking fall under the UK GDPR rules on automated decisions, which were rewritten as Articles 22A to 22D by the Data (Use and Access) Act 2025.
- A DPO is mandatory only at scale under Article 37(1), but a named one is often what a client’s supplier questionnaire asks for.
Does a recruitment agency need a DPO
UK GDPR Article 37(1) makes a DPO mandatory in three situations: a public authority, core activities that involve regular and systematic monitoring of people on a large scale, or core activities that involve large-scale processing of special category data (Article 9) or criminal offence data (Article 10). Handling candidate data is the core activity of an agency, so the question comes down to scale and to how much sensitive data you handle.
A boutique agency placing a few hundred office staff a year is usually below the line. A national agency with a large candidate database is much closer to it, and so is a healthcare, education, or security staffing business that runs health declarations and criminal record checks as routine. Those are the cases where we would expect the answer to be yes. If you are not caught, Article 37(4) still lets you appoint one voluntarily (often the cheaper route to answering a client’s due diligence questions than rebuilding the answers every tender). Our do I need a DPO page walks through the test in more detail.
Controller, processor, or both
The ICO’s draft guidance on recruitment and selection is direct on this: recruiters are likely to act as controllers in most circumstances. Keeping a candidate on file for other roles, paying temporary workers yourself, or holding records because employment agency law requires it all mean you decide why and how that data is used. That makes you the controller for it.
You can still be a processor for a narrow campaign run entirely on an employer’s instructions, and then a written contract under Article 28 is needed. Many agencies end up as both across the same client relationship, so the practical job is mapping which data sits in which role and making sure your terms with clients say the same thing. We usually do this as part of building your record of processing.
Sourcing candidates and privacy notices
Headhunting creates a transparency duty that agencies often miss. When you collect someone’s details from a job board or a professional network rather than from them, Article 14 requires you to tell them who you are, what you hold, why, and for how long. That has to happen within a reasonable period and at the latest within one month, or at your first contact with them if that comes sooner. The ICO’s draft guidance adds that searching recruitment-focused platforms can be reasonable, but personal social media profiles should be left alone, and direct messages to candidates count as direct marketing under PECR.
Sensitive data and criminal record checks
Health information for reasonable adjustments, diversity monitoring, and right-to-work checks all come up in ordinary placements. Health data, and diversity data that reveals ethnic origin, religion, or sexual orientation, are special category data, which needs a condition under Article 9 on top of your lawful basis. Criminal record data is stricter again: under section 10(5) of the Data Protection Act 2018 you can only process it if you meet a condition in Schedule 1 of that Act, and several of those conditions require an appropriate policy document as well. We help you decide which roles actually justify a check, record the condition you rely on, and keep the results to the people who need them.
Automated screening and AI tools
CV parsing, candidate ranking, and chatbot pre-screening are now common in agency software. Where a tool takes a significant decision about a candidate with no meaningful human involvement, UK GDPR Articles 22A to 22D apply. The candidate has to be told about the decision and be able to make representations, get human intervention, and contest it, and decisions based on special category data face tighter limits. A DPIA is usually the right starting point before you switch on a new screening tool. The ICO’s draft guidance also has a full section on automated decision-making and profiling in recruitment.
Retention and candidate requests
In Great Britain, regulation 29 of the Conduct of Employment Agencies and Employment Businesses Regulations 2003 requires agencies to keep certain records for at least one year after they last provide services to the work-seeker. That gives you a floor, and your retention schedule should add a clear deletion point for everything beyond it. Candidates can also ask for a copy of everything you hold about them. The answer is due within one month, which you can extend by two further months for complex or numerous requests (UK GDPR Article 12A), so a working subject access process is part of the job.
