Understanding the Ofcom General Conditions

The Ofcom General Conditions of Entitlement form the core regulatory obligations that apply to organisations providing electronic communications networks (ECNs) and electronic communications services (ECSs) in the UK. The regime operates through a general authorisation: no licence or notification is required, but providers automatically assume the obligations set out in the Conditions.

This page explains the structure of the Ofcom General Conditions, how they apply to providers of ECNs and ECSs, and how organisations should assess their position under the UK telecoms regulatory framework.

For guidance on scope and definitions, see Am I regulated?

Scope of the regime

The Ofcom General Conditions apply to organisations providing public ECNs or ECSs under Part 2 of the Communications Act 2003 (Act). The classification of an organisation’s activities depends on:

• whether the organisation provides an ECN or ECS;
• whether the service is made available to non-related third parties; and
• whether the service is provided for remuneration.

Ofcom’s Definition of Relevant Activity and Turnover guidelines confirm that connectivity provided to any non-related third party for consideration, even a single customer, is treated as a public ECN or ECS. Internal networks used solely within an undertaking remain private.

The regime is technology-neutral and applies equally to physical, virtualised and cloud-based infrastructures.

ECN, ECS and ISS distinctions

The definitions of ECN and ECS derive from Communications Act 2003, s 32. A service is likely to fall within the ECS definition where the provider is substantively responsible for the conveyance of signals.

The boundary with Information Society Services (ISS) has been considered by the European Court of Justice:

• In Skype (C-142/18), the SkypeOut service was held to be an ECS because users relied on Skype for connectivity to the public switched telephone network.
• In Gmail (C-193/18), Gmail was held to be an ISS because Google did not provide the transmission layer.

The test is functional: whether the provider is responsible for connectivity in substance.

Structure of the Ofcom General Conditions

The General Conditions are arranged into three Parts:

Part A – Network functioning and access

The Ofcom General Conditions apply primarily to providers of public ECNs and relate to:

• interconnection
• standards
• access to emergency services
• network integrity and resilience
• must carry obligations

Part B – Numbering and technical regulation

Part B applies to organisations using or controlling telephone numbers or providing services involving numbering functionality.

It includes obligations on:

• use of numbers;
• number allocation and withdrawal;
• number portability;
• directory information.

Part C – Consumer protection

Part C applies mainly to retail providers serving consumers and small businesses.

It includes obligations on:

• contract transparency
• switching and porting processes
• CLI requirements
• billing
• complaint handling
• access to disabled user services
• unfair sales practices
• roaming and bill-shock protections.

Although some of these Part C obligations do not apply to wholesale or enterprise-only providers, organisations must assess the applicability of each Condition on a fact-specific basis.

How the Conditions apply to different business models

Wholesale providers

Providers of wholesale connectivity, leased lines, IP transit, MVNO enablement or interconnection services are public ECS providers for the purposes of the Conditions.

Enterprise-only providers

Providers serving only corporate customers may still be public ECN/ECS providers where those customers are external to the provider’s group.

Cloud and virtualised providers

Where the core feature of a cloud or virtualised service is the provision of connectivity (e.g. SD-WAN, virtual switching, SASE), the service is likely to be an ECS.

Over-the-top communication services

OTT services are assessed functionally. Services controlling or guaranteeing connectivity may be ECS; others may be ISS.

Consequences of non-compliance

Ofcom may undertake monitoring, information requests and enforcement action. Sanctions include:

• directions to secure compliance;
• enforcement orders;
• financial penalties;
• publication of determinations;
• restrictions on number allocations or use.

For organisations operating regulated infrastructure or providing retail services, compliance programmes are expected to be documented and actively maintained.
