The European rules for digital public services

This document summarises the European rules for digital public services: accessibility, ease of use (usability) and design systems (shared rules and reusable building blocks for websites and apps). It reflects the situation on 19 October 2026. Here you will find the legal acts, the standards, the deadlines and what a government design system should offer in order to comply with them.

Note. I checked the articles in the full texts and on the official pages of the Commission, of ETSI (the European Telecommunications Standards Institute) and of the W3C (the consortium that publishes WCAG). The country-by-country catalogue: Design systems in Europe.

0. In brief

  1. There is no European law on ease of use, but accessibility is mandatory. Directive (EU) 2016/2102 on the accessibility of the websites and mobile applications of public sector bodies (the Web Accessibility Directive, WAD) covers public institutions. Directive (EU) 2019/882 on the accessibility requirements for products and services (the European Accessibility Act, EAA) has applied since 28 June 2025 to products and services, including those offered by public institutions.
  2. The technical basis is the standard EN 301 549 V3.2.1, that is, WCAG 2.1 AA (WCAG: the international web accessibility guidelines). Version V4.1.1 (2 September 2026) moves to WCAG 2.2 AA. It is not yet cited in the Official Journal of the EU (checked on 21 October 2026). Specialist sources expect the citation between the end of November and mid-December 2026. There is no official date. My recommendation: design directly to WCAG 2.2 AA.
  3. Ease of use is regulated piecemeal: Regulation (EU) 2018/1724 establishing a single digital gateway (SDG), Regulation (EU) 2024/903 laying down measures for a high level of public sector interoperability across the Union (the Interoperable Europe Act), Regulation (EU) 2024/1183 amending Regulation (EU) No 910/2014 as regards establishing the European Digital Identity Framework (eIDAS 2.0), Regulation (EU) 2024/1689 laying down harmonised rules on artificial intelligence (the Artificial Intelligence Act, AI Act), the General Data Protection Regulation (EU) 2016/679 (GDPR), Directive 2002/58/EC concerning the processing of personal data and the protection of privacy in the electronic communications sector (the ePrivacy Directive) and political declarations.
  4. The EU does not require member states to have a design system. More than 20 European countries have one; Romania does not. Portugal, Slovakia, the Republic of Moldova and Switzerland make it mandatory; Germany gives it formal funding from 2027, and France reserves it for state websites.
  5. Useful process standards: ISO 9241-210, EN 17161, ISO 24495 (plain language), the 2022 principles of the Organisation for Economic Co-operation and Development (OECD) and the UK Service Standard.
  6. Romania has accessibility legislation and monitoring by the Romanian Authority for Digitalisation (ADR), but neither a design system nor a service standard. Bill PL-x 300/2026 was submitted in February 2026, and in June 2026 ADR started a project on user-centred services. In the 2025 OECD Digital Government Index, Romania had the lowest score of the 42 countries assessed (0.24).

A1. The Web Accessibility Directive (WAD), Directive (EU) 2016/2102

It applies to the websites and apps of public sector bodies, including intranets and extranets. Content must be perceivable, operable, understandable and robust (Art. 4). The content exceptions (Art. 1(4)) include office documents published before 23 September 2018, audio-visual recordings published before 23 September 2020, live broadcasts, maps, third-party content and archives. Disproportionate burden (Art. 5) can be invoked only after an assessment and with alternatives.

Deadlines: new websites by 23 September 2019, all websites by 23 September 2020, apps by 23 June 2021.

Obligations (Art. 7): an accessibility statement, a feedback mechanism and a link to the enforcement procedure. Monitoring is annual (Commission Implementing Decision (EU) 2018/1524). Auditors first check the home page, sign-in, the contact page, one page per service, the statement and the feedback page. These are the templates that a design system would solve first.

The next national reports are expected around December 2027. As of October 2026 I had not found a proposal to revise the directive; I am still following the subject. The Commission says that accessibility overlays are not an acceptable solution.

A2. The European Accessibility Act (EAA), Directive (EU) 2019/882

It has applied since 28 June 2025. It covers products (computers, self-service terminals, e-readers) and services (electronic communications, passenger transport, banking, e-books, e-commerce, and 112 emergency calls from 28 June 2027). Microenterprises providing services are exempt. The transition lasts until 2030, and until 2045 for terminals. The provider explains in its terms and conditions how it meets the requirements (Annex V). In public procurement, the EAA requirements are mandatory (Art. 24).

Institutions' websites remain under the WAD, but the EAA applies to the services it covers regardless of who provides them, for example an institution that sells tickets online (my interpretation, not yet confirmed by a lawyer).

A3. The harmonised standard EN 301 549

Version Status on 19 October 2026
V3.2.1 (2021) The current legal reference (Commission Implementing Decision (EU) 2021/1339). WCAG 2.1 A + AA
V4.1.1 (2 September 2026) Published, not yet cited in the Official Journal, so with no presumption of conformity. WCAG 2.2 AA, also written for the EAA. Estimated citation, with no official date: end of November – mid-December 2026

V4.1.1 adds the six new criteria from WCAG 2.2, removes criterion 4.1.1 and strengthens the requirements on user preferences. It does not bring a new deadline. Clause 10 covers documents (PDF, Office).

A4. The WCAG versions

WCAG 2.1 AA is today's legal level, through EN 301 549. WCAG 2.2 (W3C, 2023; ISO/IEC 40500:2025) becomes the legal reference once V4.1.1 is cited in the Official Journal. WCAG 3.0 is only a draft (September 2026) and is not used for conformance.

New criterion in 2.2 Level What it means for a design system
2.4.11 Focus Not Obscured AA Sticky headers and banners do not hide the focused element
2.4.13 Focus Appearance AAA (not one of the six) A focus ring of at least 2 px, contrast 3:1
2.5.7 Dragging Movements AA Every drag has a single-click alternative
2.5.8 Target Size AA Targets of at least 24×24 px
3.2.6 Consistent Help A Help is in the same place on every page
3.3.7 Redundant Entry A The same data is not requested twice
3.3.8 Accessible Authentication AA No memory tests; pasting text and password managers allowed

A5. The accessibility statement: mandatory content (Decision 2018/1523)

The model is set by Commission Implementing Decision (EU) 2018/1523. The statement includes: the institution and the scope covered; the compliance status (fully, partially or not compliant); inaccessible content, with alternatives; the date and method of the assessment, with a review at least once a year; the feedback mechanism; the link to the enforcement procedure. A design system would offer a configurable statement template and a standard link in the footer.

A6. National transpositions (a selection)

A7. What the monitoring finds

The priorities of a design system, by frequency of errors: correct name, role and state (4.1.2); semantic structure; default contrast (4.5:1 for text, 3:1 for the interface); visible focus; keyboard access; templates for the statement and for feedback.

B1. Political declarations (not binding, but fundamental)

B2. The Single Digital Gateway Regulation (EU) 2018/1724, “Your Europe”

It contains the most concrete European rules on the ease of use of public services.

B3. The Interoperable Europe Act (EU) 2024/903 and the European Interoperability Framework

The regulation has applied since July 2024, with mandatory interoperability assessments from January 2025. Solutions are shared and reused, preferably under open licences. The German KERN system appears in the European catalogue of open-source software. The relevant principles of the European Interoperability Framework (EIF, 2017): user-centricity (P6), inclusion and accessibility (P7), multilingualism at every level (P9), digital by default (P10). A revised EIF is expected in 2027.

B4. The Digital Decade 2030 and the eGovernment Benchmark

Decision (EU) 2022/2481 establishing the Digital Decade Policy Programme 2030 requires 100% of key public services to be online. The Digital Decade Board recommends measuring actual use, not only availability.

eGovernment Benchmark 2026 (96 services, more than 14,000 websites): services for citizens 84.6; pre-filled forms 75.6; transparency 69.6 (the lowest of the core areas); support 90.0; mobile 97.4; chatbots 39.5. Fewer than 1 in 4 government websites uses a recognisable government domain, which affects trust and protection against fraud. Conclusion: transparency patterns (progress, duration, application status) have the most room for growth; mobile friendliness is largely solved.

B5. The Commission's design and web guidelines

The Europa Component Library (ECL) v5.3.2 (8 October 2026) is the Commission's design system. The Europa Web Guide requires user research and WCAG 2.1 AA. The web writing guidelines recommend sentences of no more than about 25 words, one idea per sentence, with no jargon. The brochure “How to write clearly” has 10 tips, in all EU languages. For EU Login I found no public user experience guidelines.

B6. The European Digital Identity Wallet, eIDAS 2.0 (Regulation (EU) 2024/1183)

Its requirements work as user experience rules for any government sign-in: selective disclosure (only the data needed), the transaction history, the request to delete data, free of charge, voluntary use, with no disadvantage for those who do not use it, accessibility. Commission Implementing Regulation (EU) 2026/1731 requires the trust mark and explicit confirmation before the facial photograph is sent (details from secondary sources).

Deadlines: each state provides a wallet by 24 December 2026; regulated private sectors accept it by 24 December 2027. The Commission has not published user experience guidelines for the wallet.

B7. The OECD frameworks

The OECD Good Practice Principles for Public Service Design and Delivery in the Digital Age (2022), drawn from the standards of 14 governments, have three pillars: users' needs before those of the administration; delivery with impact, at scale (principle 6: design systems and shared components); accountability and transparency. The OECD Digital Government Policy Framework (2020) underpins the Digital Government Index, where Romania scored 0.24 in 2025, the lowest score of the 42 countries assessed.

B8. Usability and design standards

Standard What it offers
ISO 9241-210:2019 The human-centred design process: context, requirements, design, evaluation, iteration
ISO 9241-11:2018 The definition of usability: effectiveness, efficiency, satisfaction
ISO 9241-110:2020 Interaction principles, including error tolerance
EN 17161:2019 Design for All at organisational level; useful as a procurement criterion and as a governance model
ISO 24495-1:2023, -2:2025 Plain language, including for legal and administrative texts

B9. Artificial intelligence, personal data and deceptive interface patterns

C1. Is there an EU design system?

For the EU institutions, yes: ECL (EUPL licence) and eUI (internal applications). For member states, no. The EU offers shared principles (EIF, SDG), shared standards (EN 301 549) and shared infrastructure (the Interoperable Europe portal, the once-only system, the identity wallet). The Interoperable Europe Act encourages the reuse of open-source solutions, which is why many national systems use the EUPL licence.

C2. National service standards (“the rules above the design system”)

Country The standard Status
United Kingdom Service Standard (14 points) Mandatory for central government services
Germany Servicestandard, mandatory from 1 October 2025 Mandatory
France DSFR Reserved for state websites
Italy The AgID guidelines (the Italian digitalisation agency) Mandatory
Portugal, Slovakia, Republic of Moldova Decree-Law 49/2024; ID-SK; Government Decision (HG) 677/2025 Mandatory
Netherlands NL Design System Collaborative
Romania None. PL-x 300/2026 proposes shared rules for forms, errors, notifications and status tracking. The ADR project (18 months) would produce a guide and pilot services Missing

C3. The landscape of national design systems

The details are in the Design systems in Europe.

The current trend: a core of web components, with adapters for different frameworks.
