Sky UK Limited v The Office of Communications

Sky challenged Ofcom after Ofcom decided that certain Sky customers should receive end of contract notifications. That requirement did not turn on a contract wording point. It turned on whether the relevant pay TV service was an electronic communications service under the Communications Act 2003.

If the service fell within that definition, Ofcom had power to impose the relevant general condition. If it did not, the notification requirement would not apply in the same way. So the case was really about regulatory classification and the reach of Ofcom’s powers.

The appeal reached the Court of Appeal after the Competition Appeal Tribunal had already rejected Sky’s challenge. The Court of Appeal was not deciding every issue in the communications regime. It was deciding a focused point of statutory interpretation with real operational consequences for subscription businesses.

The court described Sky as providing a variety of services, including pay TV, broadband and fixed and mobile telephony. The dispute focused on parts of Sky’s pay TV offering delivered through digital satellite transmission, sometimes with an internet connection and set-top box.

The judgment grouped the relevant services together as the Sky Pay TV Service. It also noted that Sky offered OTT internet TV services, and it was common ground that those OTT services were not electronic communications services for this case.

The Tribunal had found that the Sky Pay TV Service was a single unified service rather than a bundle of separate services sold under one contract. There was no appeal against that finding. That mattered because the court had to analyse one mixed service containing several different elements.

The court said the short question was one of statutory construction. Section 32(2) and (2A) of the Communications Act 2003 define an electronic communications service. The relevant part here was the category covering a service consisting in, or having as its principal feature, the conveyance of signals. The legislation also excludes content services.

The dispute was about the order of analysis. Sky said you start with the actual overall service, including content, and ask whether that whole service mainly involves conveying signals. Only after that, Sky said, do you apply the content carve-out.

Ofcom argued for the opposite approach. It said content services must be excluded first. Then you ask whether the remaining non-content service consists wholly or mainly in the conveyance of signals. That difference in approach determined whether Ofcom could apply the relevant general condition.

The Court of Appeal dismissed Sky’s appeal. Lord Justice Zacaroli gave the main judgment, with Lord Justice Popplewell and Lord Justice Green agreeing. The court preferred Ofcom’s interpretation.

The court held that the better reading of the legislation is to exclude content services before applying the test of whether the service consists wholly or mainly in the conveyance of signals. In practical terms, content is left out of account first. The remaining non-content service is then assessed.

The court reached that conclusion by looking at the wording of the UK legislation, the wider statutory scheme, the EU-derived legislative context and the purpose of the regulatory framework. It said this reading best preserved the intended separation between content regulation and transmission regulation.

The court also considered that Sky’s approach would give the content exclusion only limited effect and could allow the transmission element of a mixed service to escape regulation where content was commercially prominent. That would sit badly with the structure and aims of the regime.

The judgment is useful because it explains not just the result, but why the court thought Ofcom’s reading made more sense. First, the court said the equivalent EU provision was more clearly read as requiring content to be excluded before the wholly or mainly test is applied. The parties agreed the domestic legislation should be construed consistently with that framework.

Second, the court emphasised the separation between content regulation and transmission regulation. In the court’s view, those regimes serve different purposes. Content regulation deals with matters such as freedom of expression, plurality, diversity, respect for human dignity and protection of minors. Transmission regulation has a different focus, including competition and customer protection in communications markets.

Third, the court said Sky’s approach risked taking the transmission element of mixed services outside regulation whenever the content element was large enough to dominate the overall package. The court considered that outcome inconsistent with the structure of the regime.

Fourth, the court rejected the argument that Ofcom’s interpretation effectively collapsed the test back into an older and broader standard. The court said the wholly or mainly test still does real work. It is applied to the non-content elements that remain after content is excluded, balancing the technical components of the service.

Fifth, the court thought Ofcom’s approach better supported legal certainty. Comparing content and transmission from an end-user perspective can involve difficult value judgments. By contrast, comparing the technical non-content elements after content is excluded is a more straightforward exercise.

The main lesson is that legal classification does not always follow your marketing message. A business may think it sells entertainment, a platform, a software experience or a premium subscription. A regulator may instead isolate the technical function of part of the service and apply a sector-specific test to that function.

This matters most where you bundle several elements into one customer offer. Hardware, software, support, content and delivery may feel like one product to the customer. But the law may separate those elements for regulatory purposes. If the non-content part mainly performs a regulated transmission function, obligations can still attach.

The case is also a reminder that customer protection rules can depend on classification questions that sit far upstream from the customer journey. If you get the classification wrong, the problem may show up later in notices, renewals, contract-end processes, systems design and internal compliance ownership.

If your business sells a mixed service, this case suggests a practical review across product, legal and operations teams. The aim is not to relabel everything as regulated. It is to make sure your classification analysis matches how the service actually works.

That review should focus on the real service being delivered, not just the headline proposition in sales copy. The court’s reasoning shows that a content-led customer proposition can still contain a non-content element that matters for regulation.

For founders, operators and in-house teams, the practical response is to treat service classification as an operational issue, not just a legal memo. If a regulator can impose conditions only on certain categories of provider, your first compliance task is often to work out whether your service falls into that category.

This is especially important where one subscription combines content, devices, software and delivery. The cost of getting the classification wrong may not appear at launch. It may appear later in customer communications, renewal systems, complaint handling and regulator engagement.

This decision should be read carefully. It does not mean every service carrying content is automatically an electronic communications service. It does not say every Sky service is regulated in that way either.

What the judgment does do is support Ofcom’s interpretation of the statutory definition for the issue before the court. It confirms that, when analysing a mixed service under this part of the Communications Act 2003, content is excluded first and the remaining service is then tested for signal conveyance.

The court also noted that Sky’s OTT services were common ground not to be electronic communications services in this case. That is a useful reminder that classification remains service-specific and fact-sensitive, even where the legal approach is now clearer.

The Court of Appeal handed down judgment on 22 August 2025. The appeal was from Competition Appeal Tribunal decisions dated 15 November 2023 and 13 September 2024. The underlying Ofcom confirmation decision was dated 19 August 2022.

For business readers, the reusable point is the court’s approach to classifying mixed services that combine content and technical delivery. That is the part of the judgment most likely to matter beyond this dispute.
