Do I need a data protection officer?

The term data protection officer appears in GDPR guidance, which leads some founders to assume every business needs to appoint one. In practice, the requirement to designate a DPO is limited to specific types of organisation and does not apply to most small businesses. Understanding when a DPO is required — and when it is not — helps founders allocate compliance effort appropriately.

Under UK GDPR, a data protection officer must be appointed by public authorities, organisations whose core activities involve large-scale systematic monitoring of individuals, and those processing special category data on a large scale. Most small businesses do not fall into these categories and are not legally required to appoint a DPO. They are, however, required to have someone responsible for data protection compliance internally — even if that person is not formally designated.

Voluntarily designating a named individual as responsible for data protection can improve compliance practices and provide a clear point of contact for the ICO and individuals making data rights requests. For businesses handling sensitive data or operating at significant scale, this may be advisable even where not legally required.
