Short answer: A DPO is only legally required in certain cases – but can be a smart choice for many businesses. You must appoint a DPO if your core activities involve systematic and large-scale monitoring of individuals, or if you process sensitive data on a large scale. A DPO advises on data protection risks and helps ensure your organisation complies with GDPR.
What is a DPO?
A DPO, or Data Protection Officer, is responsible for overseeing and ensuring an organisation’s compliance with data protection regulations. According to the EU data regulation (GDPR), it is mandatory for certain organisations to have a DPO. The Data Protection Officer must be able to provide objective advice to the company when it comes to compliance with data regulations.

Who needs a Data Protection Officer?
Companies must have a DPO if they meet at least one of the following conditions:
- Public authorities and bodies: All public authorities and bodies must have a DPO.
- Processing of personal data on a large scale: If a company carries out processing of personal data in such a way that it requires regular and systematic monitoring of affected persons on a large scale, or if the company processes special categories of personal data (e.g. health data or information about criminal convictions), they must have a DPO.
- Public authority or body processing personal data: Although not all public authorities and bodies need to have a DPO, some of them do, especially if they carry out processing of personal data that requires regular and systematic monitoring.
Although it is only mandatory for certain organisations to have a DPO under the GDPR, other companies may also choose to employ a DPO voluntarily as part of their efforts to protect personal data and comply with data protection rules. It may be good practice for any organisation that processes personal data to a significant extent to have a person responsible for data protection and compliance with privacy rules.

Who should be your responsible for your data?
To ensure independence and the possibility of providing objective advice to the company, it is a good idea to let your Data Protection Officer be an external consultant. In principle, a DPO can be an internal employee, but in that case it is problematic to ensure impartial guidance. However, we often see that it is the senior IT manager or the senior HR manager who disputes the position.
If you decide that you are not obliged to employ a DPO, it is a wise decision to document your considerations. This serves as documentation that you have thoroughly considered the need for a DPO, which can be valuable in the event of a data audit.

FAQ about DPOs
1. Do we need to register our DPO?
No, if your organisation has appointed a Data Protection Officer, you can (voluntarily) notify the ICO, but it’s not mandatory. However, it’s recommended to make it easier for the authority to contact the right person during audits.
2. Can an employee hold multiple roles?
Yes – but only if there is no conflict of interest. For example, your Head of IT typically cannot act as DPO.
3. How much does it cost to hire an external DPO?
It varies – but many organisations choose flexible arrangements where the DPO acts as an advisor on an hourly or project basis.
