UK telecoms regulation advice: 5G mobile network infrastructure

Telecoms Regulation

If you provide electronic communications networks or services in the UK, regulation applies to your business from day one. Under the Communications Act 2003 and Ofcom’s General Conditions, you must meet obligations on consumer protection, interconnection, numbering, emergency access and security, and those obligations cover more services than most new providers expect. Rob Bratby is ranked Chambers UK Band 2 (Telecommunications) and has more than 30 years’ experience across the regulator, senior in-house operator roles and international law firms, including a one-year secondment to Oftel.

A general counsel or regulatory lead at an operator is usually asking a settled question about General Conditions, spectrum, access regulation or Ofcom enforcement. A founder is usually asking a prior one, whether the network or service falls within the PECN and PECS definitions at all, and what authorisation, security and consumer obligations follow if it does.

The regulatory framework

Ofcom regulates electronic communications under the Communications Act 2003. Under the Act, Ofcom may set General Conditions of Entitlement under section 45, impose SMP conditions under section 45 following a market power determination under sections 78 to 86, and regulate spectrum, numbering and interconnection. Operators with Code operator status have statutory rights under the Electronic Communications Code (Schedule 3A) to install and maintain apparatus on land for network deployment.

Ofcom’s General Conditions apply to all providers of electronic communications networks and services. They cover contract terms, billing, number portability, emergency call access, complaints handling and quality of service. There is no individual licensing regime and no grace period: obligations apply from day one. Where Ofcom designates an operator with significant market power in a defined market, additional obligations follow under sections 87 to 91A, including wholesale access requirements, cost orientation and non-discrimination.

Providers also have security duties. Under the Telecommunications (Security) Act 2021, providers must identify, reduce and manage security risks to their networks and report security compromises to Ofcom. Under the Product Security and Telecommunications Infrastructure Act 2022, manufacturers and distributors of connectable products have duties, and Parliament used the same Act to amend the Electronic Communications Code and strengthen infrastructure sharing obligations. Ofcom sets the regulatory framework for fixed wholesale markets in five-year cycles through its Telecoms Access Review, deciding SMP designations and the access obligations that flow from them.

Why telecoms regulation matters

Telecoms operators must meet more obligations each year. General Conditions, security obligations, spectrum conditions and infrastructure sharing requirements overlap, and complying with all of them is broad and costly work. An operator that gets it wrong risks enforcement, a delayed transaction and lost commercial opportunity. In-house teams at established operators must meet an expanding set of obligations that need specialist interpretation. They have to read the General Conditions, the security regime and the access rules together, as one exercise.

Regulator, operator and Advisor perspectives

On every telecoms instruction we draw on three perspectives: the regulator’s, the operator’s and the advisor’s. Rob spent a year on secondment to Oftel and saw how the regulator assesses applications and sets enforcement priorities. Through his current fractional General Counsel appointments at TOTSCo, TelXL, Core Communication and the UK Payments Initiative, he sees how General Conditions, security duties and access obligations work inside an operating business. The advisor’s perspective comes from more than 30 years advising on operator M&A, spectrum licensing, interconnection disputes and Ofcom investigations, in private practice and in-house. Read more about how these three perspectives combine on Why Bratby Law.

Frequently asked questions about telecoms regulation

How do I know if my service is in scope of Ofcom regulation?

You are in scope if you provide an electronic communications network or service as defined in the Communications Act 2003. Since 21 December 2020 the definition has been a closed list of three types: an internet access service, a number-based interpersonal communications service, and any other service consisting in, or having as its principal feature, the conveyance of signals, including transmission services used for machine-to-machine services. MVNOs, managed VoIP services and IoT connectivity providers fall within it. A cloud or software platform that buys connectivity from another provider is outside it unless it takes responsibility for the conveyance of signals itself. A provider inside the definition must comply with the General Conditions from the start of operation.

What are the General Conditions and when do they apply?

The General Conditions are regulatory obligations made by Ofcom under section 45 of the Communications Act 2003. They cover consumer protection, interconnection, numbering, quality of service, emergency access and transparency. They apply from day one of operation. There is no grace period.

What is SMP regulation and how does it affect access seekers?

Where Ofcom designates a communications provider with Significant Market Power in a defined market, it imposes obligations that include wholesale access, cost orientation and non-discrimination. If you are seeking access to an SMP-designated provider’s network, the provider must offer access on the terms, pricing methodology and dispute resolution route those obligations set. An access seeker can escalate to Ofcom where the SMP provider fails to comply.

What happens if Ofcom investigates me?

Ofcom has powers to investigate potential breaches of General Conditions and spectrum licence conditions. You have rights to see the evidence, make representations and request a settlement meeting. Outcomes range from a no-breach decision to a financial penalty. For the process, the arguments available and settlement, see the complaints and investigations page.

How does spectrum regulation work?

Ofcom allocates spectrum by licence, and sets in each licence the technical parameters, geographic coverage, duration and conditions of use. For variation, renewal and the consequences of operating outside the licence conditions, see the spectrum page.

What are Code Powers?

Operators with Code operator status have statutory rights under the Electronic Communications Code (Schedule 3A, Communications Act 2003) to install and maintain apparatus on land. To exercise these rights, you must follow the statutory process for notice and negotiation. For obtaining Code operator status, exercising the rights and resolving disputes with landowners, see the Code Powers page.

What security obligations apply to telecoms operators?

Under the Telecommunications (Security) Act 2021, operators must identify and manage security risks and report incidents to Ofcom. Equipment security and supply chain duties fall on operators under the same regime, in the Electronic Communications (Security Measures) Regulations 2022 made under those sections. The Product Security and Telecommunications Infrastructure Act 2022 is a different Act with different addressees: manufacturers, importers and distributors of consumer connectable products have product security duties under it. For compliance, incident response and dealings with Ofcom, see the telecoms security page.

What is interconnection regulation?

Operators must interconnect to deliver calls and data. The parties negotiate the terms commercially, within their regulatory obligations. If they cannot agree, either party can refer a dispute about network access to Ofcom under section 185 of the Communications Act 2003, whether or not either has SMP, and Ofcom can determine the terms. For agreement terms, the regulatory constraints and dispute resolution, see the interconnection regulation page.

Do I need to worry about the NSIA for a telecoms acquisition?

A buyer of a telecoms operator or critical infrastructure may have to notify the acquisition under the mandatory regime in the National Security and Investment Act 2021. The mandatory regime covers public electronic communications networks and services above certain thresholds, together with associated facilities, submarine cable systems and cable landing stations, and the repair and maintenance of those assets.

How does Bratby Law charge for telecoms regulation advice?

We quote a fixed fee for an initial review once we have the documents, and scope each later instruction individually. A first call scopes the work only; we do not give advice before the engagement is agreed. For ongoing advisory work, we offer fractional General Counsel arrangements with predictable monthly costs. Scope and cost are agreed before work begins. We use an AI system for research, drafting and checking, and Rob Bratby signs off all written advice; see How we use AI.
