Are you thinking about becoming a DPO (data protection officer)? You’re not alone. It’s one of the fastest-growing privacy roles in the UK.
For many organisations, appointing a DPO is a legal obligation under the UK GDPR (General Data Protection Regulation). For others, voluntarily appointing a DPO enables them to demonstrate accountability and manage the growing complexity of privacy regulation.
For mid-career professionals, the DPO role represents an attractive career move. It draws on compliance, risk management, IT, and legal expertise, but positions the individual as an independent voice reporting directly to senior management. Salaries are competitive, the role is in demand across multiple sectors and skilled practitioners often find they can progress rapidly to senior privacy, governance or security positions.
This guide explains what the role involves, which organisations must appoint a DPO, and how you can position yourself for success. It sets out a step-by-step pathway – from building a foundation in data protection law through to becoming a certified DPO – and provides practical advice on what employers are looking for.
What the DPO role involves
Article 39 of the UK GDPR sets out the DPO’s responsibilities, which cover every aspect of data protection compliance across the organisation. A DPO must:
- Inform and advise the organisation, and its staff, about data protection obligations.
- Monitor compliance with the Regulation, including audits, training, and policy enforcement.
- Advise on and monitor DPIAs (data protection impact assessments).
- Act as a contact point for the ICO and cooperate with investigations.
- Handle requests from individuals, such as DSARs (data subject access requests).
- Raise awareness and train staff at all levels on privacy responsibilities.
Unlike other compliance roles, the DPO must be independent. Article 38 makes clear that the DPO:
- Cannot receive instructions on how to exercise their tasks.
- Cannot be dismissed or penalised for performing their duties.
- Must report directly to the highest level of management.
This independence is essential. A DPO must sometimes give unwelcome advice – for example, warning that a planned project carries high privacy risks or advising the board that a breach must be reported. The role is therefore a blend of technical knowledge, legal expertise, and leadership.
Who needs a DPO?
Under Article 37, organisations must appoint a DPO if they are:
- A public authority or body (excluding courts acting in a judicial capacity).
- Carrying out regular and systematic monitoring of data subjects on a large scale.
- Conducting large-scale processing of sensitive data (such as health, biometric, or criminal records).
Sectors where DPOs are common
- Public sector: Central and local government, regulators, educational institutions.
- Healthcare: NHS trusts, private hospitals, clinical research organisations.
- Financial services: Banks, insurers, fintech firms handling large amounts of personal and financial data.
- Technology and telecoms: Online platforms, ISPs, telecoms providers conducting large-scale profiling or monitoring.
Failing to appoint a DPO when required risks fines of up to £8.7 million or 2% of annual global turnover.
Note on the DUAA: The Data (Use and Access) Act 2025 has reduced mandatory DPO requirements for certain organisations. However, many still appoint DPOs voluntarily. Employers recognise that having a DPO demonstrates accountability and builds trust with regulators, customers and partners.

Career routes into the role
There is no single route into becoming a DPO. The Regulation itself requires only that the individual has “expert knowledge of data protection law and practices” appropriate to the organisation’s processing activities.
Many people arrive from adjacent disciplines, including:
- Compliance and risk management
Professionals already dealing with regulatory frameworks, audits, or risk assessments. - IT and information security
Individuals with technical expertise in systems, networks, or security controls who expand into data protection. - Legal and audit functions
Lawyers, auditors, or governance specialists with strong regulatory knowledge.
In many small and medium-sized enterprises, it’s common for IT managers, operations directors or HR leads to become “accidental DPOs”, handling privacy by default because no one else can.
These people often discover they are, in effect, performing DPO tasks without formal recognition or training. Formalising the role through structured training not only strengthens compliance but also provides career leverage.
A step-by-step path to becoming a DPO
Becoming a DPO involves building knowledge, applying it in practice, and demonstrating independence and leadership.
Step 1: Build foundations
Start with GDPR Foundation training. This provides baseline understanding of:
- The structure and principles of the UK GDPR.
- The rights of data subjects.
- The obligations of controllers and processors.
This level of knowledge is suitable for anyone who handles personal data or is considering a move into privacy.
Step 2: Practitioner training
Progress to the Certified GDPR Practitioner course. This covers the practical skills you need to function as a DPO, including:
- Conducting DPIAs.
- Managing DSARs.
- Handling data breaches.
- Building compliance frameworks.
At this level, learners gain hands-on case study experience and prepare for the real-world challenges of advising senior management.
Step 3: On-the-job experience
Knowledge must be reinforced through practice. At this stage, aim to:
- Shadow or support an existing DPO.
- Take responsibility for discrete tasks such as DSAR responses or drafting policies.
- Participate in audits or risk assessments.
- Engage directly with business units to provide advice.
Step 4: Advanced certification
Formalise your expertise with the Certified Data Protection Officer (C-DPO) course. This advanced qualification is not legally mandated, but many employers now expect it. It demonstrates professional commitment and provides assurance that you can operate independently at senior level.
Employer expectations vs legal requirements
Legal requirement: Article 37(5) requires “expert knowledge of data protection law and practices.”
Employer expectations: Job adverts frequently specify recognised certifications (IBITGQ, BCS, IAPP), practical experience handling DSARs and DPIAs, and confidence in audits.
In other words, the law requires expertise, but the market expects evidence of structured training and applied skills.
Required knowledge and desirable qualifications
At a minimum, a DPO must understand:
- The UK GDPR and DPA 2018, and – for organisations that process EU residents’ personal data, the EU GDPR.
- Data subjects’ rights, and the obligations of data controllers and processors.
- Risk management principles and how to apply a risk-based approach to personal data processing.
In practice, employers also value:
- Professional certifications such as IBITGQ C-DPO, BCS Practitioner Certificate, or IAPP CIPP/E.
- Demonstrable experience in data protection compliance, particularly handling DSARs, running DPIAs and advising senior management.
- Complementary expertise, such as auditing, information security, legal compliance or risk management.
Real-world tips
Analysis of current DPO job adverts in the UK highlights many themes. Employers often ask for:
- Practitioner-level certification.
- Proven ability to design and embed data protection policies.
- Experience handling regulator engagement (ICO).
- Communication skills to brief boards and influence managers.
To stand out, also focus on developing:
- Communication skills – translating regulatory obligations into plain English for non-specialists.
- Policy writing – producing clear, actionable data protection policies and procedures.
- Risk management: Framing data protection issues in terms of organisational risk.
- Leadership and influence – building a privacy culture across all departments and gaining senior management buy-in.
Conclusion
Becoming a DPO combines structured training with practical experience. The role is demanding but offers long-term career value as organisations continue to prioritise privacy and accountability.
A clear training pathway can help you position yourself:
- GDPR Foundation for baseline knowledge.
- GDPR Practitioner for hands-on skills.
- Certified DPO for formal recognition.
Whether your organisation is legally obliged to appoint a DPO or chooses to do so voluntarily, employers increasingly expect certification, hands-on experience, and the ability to advise confidently at board level.
If you are considering your next career step, the DPO role offers independence, influence, and the chance to be at the heart of how organisations use and protect data in the UK.
Start your journey today with GDPR Foundation training, then progress to Practitioner and C-DPO.
