For businesses established outside the European Union, including those in the UK, USA, Canada, or Australia—the "long arm" of the GDPR creates a specific legal requirement that is often overlooked until an audit begins: the EU Representative.
If you offer goods or services to individuals in the EU, or monitor their behaviour (e.g., through cookies or analytics), but do not have a physical office, branch, or subsidiary within the EU, Article 27 of the GDPR requires you to appoint a legal representative on European soil.

The requirement for an EU Representative is triggered by Article 3(2) of the GDPR. If you answer YES to both of these questions, appointment is mandatory:
In 2026, the distinction between an EU Representative and a UK Representative is a major enforcement focus.
Since the UK is no longer part of the EU, companies without a physical presence in these territories face a specific "double" requirement regarding Article 27:
Targeting the EU? You must appoint an EU Representative established in a Member State (e.g., Spain).
Targeting the UK? You must appoint a UK Representative established within the United Kingdom.
Targeting Both? You are legally required to appoint two separate representatives. One representative cannot satisfy the legal requirements for both jurisdictions.

An EU Representative is a "natural person" or "legal entity" (a specialised firm) established in the EU that acts as your local face of compliance.
Exemptions: Occasional, low-risk processing only.

Choosing Spain as your "base" for an EU Representative offers several strategic advantages for English-speaking businesses:
Size does not matter. The law applies based on who you target, not how many employees you have. If you sell specialized software to 50 clinics in Madrid from your office in London, you are legally required to have an EU Representative.
No. The representative must be "established." This means they must have a physical presence and the capacity to actually handle inquiries. The AEPD has previously fined companies for having "ghost" representatives who do not respond to requests.
In 2026, you should look for a provider that offers Records of Processing Activities (RoPA) hosting. Since your representative must be able to provide your ROPA to the AEPD upon request, they need a secure, real-time portal into your compliance status.
