A Data Protection Officer (DPO) is the designated individual within an organisation who is responsible for monitoring, advising and organising compliance with UK GDPR and other data protection laws. They act as the main point of contact for data protection matters – both internally with staff and externally with the Information Commissioner’s Office (ICO).
Under Article 39 of the UK/GDPR, the DPO’s key responsibilities include:
Importantly, the DPO is not personally liable for any non-compliance with data protection compliance – the organisation is legally responsible. To ensure impartiality, the DPO must be free from conflicts of interest.
Under UK GDPR appointing a DPO is required when the organisation is:
An organisations “core activities” are essentially its primary business objectives. If you need to process personal data to meet these then the likelihood is that you will need to appoint a DPO.
Data which falls into “Special Categories” include anything involving racial or ethnic origin, sex, sexual orientation, personal health and/or political / religious beliefs.
Data processed on a “large scale” refers to handling significant volumes of personal data. For example, tracking passenger movements across Manchester’s tram network through bank cards.
The size of the company doesn’t matter– the requirement is based on the nature and scale of data processing, not the number of employees.
Even if your organisation isn’t legally required to appoint a DPO, doing so voluntarily can ensure compliance with data protection laws more generally.
There are no formal qualification requirements that a DPO must have, but they must be independent, have an expert knowledge of data protection laws, be adequately resourced and report to the highest management level in the organisation.
You do not need to hire externally if there is already an employee of the organisation capable of carrying out a DPO’s role effectively, but it is imperative that they have the requisite knowledge of data protection laws. It can be more beneficial, particularly for smaller organisations, to outsource the DPO position to a specialist company.
Once a DPO has been appointed, an organisation must:
Under Article 38 of the UK GDPR, organisations must support their DPO by:
Appointing and supporting a qualified DPO is a key part of demonstrating compliance with relevant data protection legislation. Failure to do so can have serious consequences such as financial penalties, regulatory action, reputational damage and legal liability.
