How to Address EU & UK Company Disclosure Rules with Minimal Effort

~ 5 min read

Introduction

Publishing accurate company information isn’t just a business best practice; it’s a legal requirement across multiple jurisdictions. Regulations, including the EU DSA, France’s LCEN, Germany’s TTDSG “Impressum” rules, and the UK’s EC Directive Regulations, all require businesses to make legal identity, registration, and contact information accessible online.

Managing these disclosures across multiple websites, apps, and marketplaces can be challenging. Each update often requires coordination between legal, marketing, and technical teams, which can lead to delays or inconsistencies. Centralized tools that automate publication can help simplify the process and reduce the risk of omissions.

Why company disclosures matter under EU and UK law

Company disclosures provide transparency and help build trust between businesses and their customers. They also make it easier for authorities to enforce consumer protection rules. Without clear information, customers may find it difficult to verify a business’s legitimacy or know where to address concerns.

In the EU and UK, disclosure obligations also support broader policy goals such as fair competition, online safety, and accessibility.

Core legal frameworks requiring company disclosures

  • EU Digital Services Act (DSA) – Requires online service providers to publish clear, easily accessible information identifying the service provider and explaining how users can contact them. This applies to platforms, marketplaces, hosting services, and more.
  • France – LCEN – France’s Loi n° 2004-575 (LCEN) requires online publishers to include business identification information such as name, address, registration details, and contact methods. The law also outlines additional obligations for professional publishers and online service providers.
  • Germany – TTDSG – The Telekommunikation-Telemedien-Datenschutz-Gesetz combines telecom and telemedia disclosure rules. German websites are required to provide clear “Impressum” information, including company name, address, registration number, and responsible contact person.
  • UK – EC Directive Regulations – These regulations require businesses providing online services to supply their name, geographic address, email address, company registration number, and any trade or professional registration details.

What businesses must disclose online

While the exact requirements vary by jurisdiction, common elements include:

  • Legal or trading name
  • Registered office address
  • Contact information (email, telephone)
  • Registration number and issuing authority
  • VAT identification number (where applicable)
  • Details of relevant licenses or supervisory authorities
  • Accessibility statements where required

Common challenges in managing disclosures

  • Multiple touchpoints – Websites, mobile apps, partner marketplaces, and internal portals all require updates.
  • Regulatory variation – Differences in disclosure rules between jurisdictions.
  • Version control – Being sure that the latest information is published everywhere.
  • Coordination – Aligning legal, marketing, and IT departments on updates.

These operational challenges increase the risk of non-compliance and expose organizations to enforcement action or user confusion.

Penalties for non-compliance

Failure to publish the required information can lead to administrative fines, legal action, or reputational harm. For example:

  • Under LCEN, fines can reach €75,000 for individuals and €375,000 for legal entities.
  • Under TTDSG, violations can result in administrative penalties.
  • In the UK, enforcement actions can be brought by Trading Standards or other authorities.

The cost of non-compliance can far outweigh the effort of maintaining accurate online disclosures.
