The accessibility mandate driving caption demand across Europe in 2026

If you publish video for audiences in the EU, captioning became a legal obligation on 28 June 2025, when the European Accessibility Act came into force. 2026 is the first full year of enforcement. National regulators are now checking, and content teams that assumed one English caption file would do are finding that each market expects captions in its own language, to its own standard.

That is why demand for captions, subtitles for the deaf and hard of hearing (SDH) and live captioning has risen across Europe this year.

What the European Accessibility Act requires

The European Accessibility Act (EAA, Directive 2019/882) sets EU-wide minimum accessibility requirements for a range of products and services sold to consumers. It is a directive, so each of the 27 member states has transposed it into national law, with its own regulator and its own penalties. The requirements have applied to new products and services since 28 June 2025.

For video, the services in scope include:

• Services that give access to audiovisual media - streaming platforms, broadcaster apps, electronic programme guides and the players that sit around the content
• E-commerce, including product videos and explainers on consumer-facing websites
• E-learning and consumer-facing digital platforms that distribute video as part of the service
• Banking, transport, telecoms and e-books, where video is used to explain or support the service

Scope follows the customer rather than the head office. A UK or US company selling to consumers in France or Germany online is in scope in the same way a Paris-based company is.

Two groups get relief. Micro-enterprises - fewer than ten employees and turnover under €2 million - are generally exempt from the service requirements. And there is a transitional period for pre-existing content and for service contracts agreed before June 2025, running to 28 June 2030 at the latest. Anything published after 28 June 2025 is subject to the full requirements straight away, and the transitional period does not extend to audiovisual media services such as streaming platforms.

The EAA itself mostly covers the service: the player, the navigation and the way access features reach the viewer. The duty to make the content accessible comes from the Audiovisual Media Services Directive, covered next. Regulators read the two together: if the video is there, the captions should be too.

The other two pieces: AVMSD and EN 301 549

Two older instruments sit behind the EAA and do most of the work for video content.

The Audiovisual Media Services Directive (AVMSD), revised in 2018, requires broadcasters and on-demand services to make their content "continuously and progressively more accessible" to people with disabilities, and to report to national regulators on how they are doing it. That is where the duty to caption the programme itself sits. National regulators have turned that into quotas, reporting cycles and, increasingly, published league tables.

EN 301 549 is the harmonised European standard that says what "accessible" means in technical terms. It incorporates the Web Content Accessibility Guidelines (WCAG), and for video it maps to four criteria: captions for pre-recorded content, audio description for pre-recorded content, captions for live content, and audio description or an equivalent alternative. Meeting EN 301 549 is the recognised way to show EAA conformity, so it is the standard your captions will be judged against.

So the EAA requires the service to be accessible, AVMSD requires the content to be accessible, and EN 301 549 defines what accessible means. Captions appear in all three.

Captions, not subtitles

The mandate asks for captions. A subtitle track renders the dialogue, usually translated, for a viewer who can hear the soundtrack. A caption track, or SDH, is written for a viewer who cannot: it carries the dialogue plus speaker identification, sound effects, music cues and tone where tone changes the meaning.

A plain subtitle file does not meet the standard. Neither does an unchecked automatic transcript. Regulators and the standards bodies both expect captions to be accurate, synchronised with the audio, complete, and present whenever there is speech. In practice that means:

• Same-language captions on all pre-recorded video with speech
• Speaker labels and non-speech information where the viewer would otherwise lose meaning
• Timing that follows the dialogue and respects shot changes
• A closed track the viewer can turn on, resize and read with assistive technology, rather than text burnt into the picture

Automatic speech recognition gives you a usable first pass in seconds. A human reviewer then corrects names, numbers and mis-hearings and signs the file off. That review is the step a regulator will ask about.

Every market, every language

The EAA asks for an accessible version of your video in each market you serve, in that market's language. English captions on a product video shown to German consumers do not satisfy the German requirement. A French audience needs French captions, and French audio description if you offer audio description at all.

The SDH conventions also differ by country. Line length, reading speed, how speakers are identified and where captions sit on screen all vary between, say, Germany, France and the Nordics. A caption file that passes in one market will not automatically pass in the next.

A company selling into five EU markets with a few hundred videos therefore has five parallel compliance projects, each with its own language, standard and deadline. Teams that plan this purely as an accessibility task tend to find the language gap late, when the cost has already grown.

The workable approach is to treat captioning and localisation as one workflow: produce the source-language caption track to SDH standard once, then translate from that track into each target language with the timing already in place, rather than re-timing every language from scratch.

Live content and events

WCAG and EN 301 549 include a criterion for captions on live content, and the EAA applies it to any live stream, webinar, product launch, investor call or town hall that forms part of a consumer-facing service. Broadcasters have had live captioning obligations for years. For everyone else it is new, and it is where much of this year's demand is coming from.

The bar for live is sensibly lower than for pre-recorded: accuracy and latency are judged against what is achievable in real time, and a corrected recording with full captions published promptly afterwards is expected. But "we'll caption the replay" is no longer enough on its own for a significant live event.

Real-time AI captioning has brought the cost down. Live captioning used to mean booking a stenographer for each language; a single live feed can now be captioned and translated into dozens of languages at once, with a human monitoring where the stakes warrant it.

Live video is where accessibility obligations are least defined and most likely to tighten. The EAA does not spell out a duty to subtitle live streams, but conformity for any website or app in scope is judged against EN 301 549, which carries WCAG's live captions criterion at level AA, and the AVMSD obliges broadcasters and on-demand services to keep extending access year on year under national quotas that are already rising. Waiting for a regulator to name live content explicitly means building the capability under pressure, in the middle of an event cycle, rather than on your own timetable.

There is also a plain commercial case. Live captions make a product launch, webinar or investor call followable in a noisy office or on mute, searchable afterwards, and immediately translatable into every language the audience speaks. Real-time AI captioning has removed the cost barrier that used to justify captioning only the replay, so the organisations subtitling their live output now are meeting the standard the law is heading towards and reaching a larger audience in the process.

What this means for UK companies

The UK did not transpose the EAA, so a British company has two sets of rules to think about.

At home, the Equality Act 2010 imposes a duty to make reasonable adjustments, and Ofcom's Code on Television Access Services sets captioning quotas for broadcasters and, since 2024, on-demand services. Public sector bodies also carry the Public Sector Bodies Accessibility Regulations, which point at the same WCAG criteria.

In the EU, scope follows the customer. If a UK business sells to consumers in any member state - through a website, an app, an e-learning platform or a streaming service - the EAA applies to that activity as if the business were based there, and the relevant national regulator can enforce it. For most British firms with European customers, the sensible move is to adopt EN 301 549 as the house standard and apply it everywhere. It satisfies both regimes and avoids running two caption workflows.

What to do now

1. Audit by market, not by asset. List the EU countries where you have consumers, then work out which video is in scope in each. Start with high-traffic, public-facing content.
2. Split new production from the backlog. Build captions into the production workflow for anything published since June 2025, so nothing goes out without them. Prioritise the back catalogue by exposure and risk, and use the transitional period to work through it rather than as a reason to wait.
3. Set the quality bar in writing. Adopt EN 301 549 as your standard and define what a compliant caption file looks like for each market: language, speaker labelling, reading speed, positioning.
4. Fix the review step. Decide where human checking happens, who does it and how it is recorded. The audit trail is what a regulator will ask for.
5. Plan language coverage alongside compliance. For each market, check whether you have captions in that market's language, to that market's standard.
6. Cover live. Identify the live events that fall within a consumer-facing service and put real-time captioning in place for them.

The organisations managing this at lowest cost build captions into the production of every video, in every language they publish, rather than commissioning them afterwards.
