Telecoms ombudsman regulatory powers: Ofcom, GC C4 and the ADR schemes
In short: Telecoms ombudsman regulatory powers do not exist as a separate statutory regime. Communications Ombudsman and CISAS are private bodies approved by Ofcom under section 54 of the Communications Act 2003 to resolve individual consumer complaints. Statutory regulatory and enforcement powers, including penalties up to 10 per cent of turnover, sit with Ofcom alone.
Telecoms ombudsman regulatory powers prompt regular questions from in-house counsel and consumer advisers, and the answers differ across sources. If a customer has a complaint against a broadband, mobile or landline provider that the provider will not resolve, where do they go, and who actually has the power to do something about it? The phrase “telecoms ombudsman” is in common use, but it covers two different mechanisms that work in different ways and sit under different parts of the law. Confusing the two leaves operators with the wrong compliance picture and consumers at the wrong door. This piece sets out the position in plain terms.
What the telecoms ombudsman is, and what it is not
There is no single “telecommunications ombudsman” in the UK. Ofcom has approved two Alternative Dispute Resolution (ADR) schemes for the telecoms sector under section 54 of the Communications Act 2003: Communications Ombudsman (formerly Ombudsman Services: Communications, renamed in July 2023) and the Communications and Internet Services Adjudication Scheme, known as CISAS. Both are private bodies. Under General Condition C4, membership is required of any provider supplying public electronic communications services to “Consumers, Microenterprise or Small Enterprise Customers or Not-For-Profit Customers”. A Microenterprise or Small Enterprise Customer is defined as one acting in the course of a business “for which not more than 10 individuals work (whether as employees or volunteers or otherwise), but who is not himself a Communications Provider”, so the threshold counts volunteers as well as employees, and a customer that is itself a provider is outside the schemes whatever its size. The schemes resolve individual disputes and make awards binding on the provider that the consumer can choose to accept or reject. They are a redress mechanism, not a regulator.
Does the telecoms ombudsman have regulatory powers?
No. Telecoms ombudsman regulatory powers, in the sense of rule-making or industry-wide enforcement, do not exist. The schemes cannot make rules, open enforcement investigations, fine operators or direct industry behaviour. They work case by case on individual complaints and their decisions bind only the parties to the complaint. They cannot set rules of general application, they cannot investigate a provider on their own initiative, and they cannot impose penalties for breach of regulation. They have no statutory function beyond the case-handling that section 54 permits Ofcom to approve.
When the scheme finds for a consumer, the remedy is compensation, an apology or a service correction directed at that consumer. Nothing about that decision changes the law or the rules that bind the wider market.
Where telecoms ombudsman regulatory powers actually sit: with Ofcom
Statutory regulatory power over telecoms providers sits with Ofcom under the Communications Act 2003. To the extent that the question of telecoms ombudsman regulatory powers arises at all, the answer is that those powers, in any rule-making or enforcement sense, are Ofcom’s. Ofcom designates and supervises Communications Providers, sets the rules they must follow, opens investigations and imposes penalties. The relevant statutory machinery runs through three layers.
First, section 45 empowers Ofcom to set General Conditions of Entitlement, which apply automatically to every Public Electronic Communications Network and Public Electronic Communications Service provider. Section 52 requires Ofcom to use that power to set conditions covering complaints handling, dispute resolution between providers and their customers, and remedies and redress. That is the legal route by which GC C4 binds operators to participate in an ADR scheme.
Second, section 54 gives Ofcom the power to approve dispute resolution procedures. Approval is conditional: Ofcom must be satisfied that the scheme is independent of both the regulator and the providers, that the procedures are easy to use, transparent, non-discriminatory and effective, that consumers can use them free of charge, that disputes are properly investigated, and that the scheme can make and enforce awards of compensation. Ofcom can attach conditions to its approval, keep the schemes under review, modify the conditions and withdraw approval altogether. The schemes operate in a regulatory cage that Ofcom builds and maintains.
Third, the enforcement powers over a general condition sit with Ofcom under section 96A and the sections that follow it. Section 94 is the notification provision for an SMP apparatus condition and is not the route for a General Condition. If a provider contravenes a General Condition, including GC C4, Ofcom may serve a notification of contravention, allow the provider to make representations, and then issue an enforcement notification or impose a financial penalty. The penalty cap under section 97 is 10 per cent of turnover of the relevant business. Ofcom also has separate jurisdiction to resolve disputes between providers (rather than between providers and consumers) under Part 2 Chapter 3 of the Act, sections 185 to 191, with appeals to the Competition Appeal Tribunal under section 192. None of those powers sit with the ADR schemes.
| Function | Ofcom | Approved ADR scheme (Communications Ombudsman or CISAS) |
|---|---|---|
| Source of power | Communications Act 2003, ss.45, 52, 54, 96A-96C, 97, 185-191 | Approval by Ofcom under CA 2003 s.54; contractual binding through scheme membership |
| Make rules of general application | Yes (General Conditions, SMP conditions, codes of practice) | No |
| Open investigations on own initiative | Yes (sections 96A to 96C and 97) | No |
| Resolve individual consumer complaints | No (does not adjudicate individual cases) | Yes (the core function) |
| Impose financial penalties | Yes, up to 10 per cent of relevant turnover under s.97 | No (can award compensation in the individual case only) |
| Resolve disputes between operators | Yes, under ss.185-191 | No |
| Appeal route from decisions | Competition Appeal Tribunal under s.192 | None at scheme level; consumer may decline the award and litigate; provider is bound |
How telecoms ombudsman regulatory powers play out in practice
For operators, the practical effect is that GC C4 and the Approved Code of Practice for complaints handling are the live compliance items, not the ombudsman scheme rules themselves. Providers must operate a complaints process that conforms to the Approved Code, must signpost their customers to the relevant ADR scheme, and must take part in the scheme’s procedure when a case is referred. None of these obligations are functions of the ADR scheme; they are conditions imposed by Ofcom under GC C4, and they form the operational expression of telecoms ombudsman regulatory powers as the question is usually asked.
Following Ofcom’s 2025 review of ADR in the telecoms sector, the trigger period for ADR access dropped from eight weeks to six weeks for complaints raised on or after 8 April 2026. New entrants, MVNOs, altnets and resellers building out their compliance architecture should remember that the obligations sit on the entity supplying the service to the end consumer; allocation between wholesale and retail in MVNO and reseller agreements should be drafted with that in mind.
For consumers, the route is straightforward but limited in what it can achieve. Paragraph 12 of the Annex to Condition C4 requires a provider to “immediately issue an ADR Letter to the Complainant if the Complaint remains unresolved after six weeks have passed since the date on which the Complaint was first received”. Under paragraph 11 the ADR Letter must issue with no waiting period at all where three conditions are met together: the provider has told the customer the outcome of its investigation, the customer has said that outcome does not resolve the complaint, and the provider does not intend to take further steps that would produce a different outcome. That is the position usually called deadlock, and “ADR Letter” rather than deadlock notice is the term the General Conditions use. The scheme can order compensation, a fix or an apology. What it cannot do is reopen Ofcom’s regulatory rules, change the way a provider treats other customers, or impose a penalty for breach. The line between Ofcom’s regulatory powers and the schemes’ dispute resolution role is the line between regulation and redress.
Where a customer wants the regulator to look at a systemic problem, the route is to complain to Ofcom directly; where a customer wants damages or an injunction beyond what the scheme can offer, the route is to court.

Viewpoint
The “ombudsman” label is hard to dislodge in plain English, but it is worth being precise about it in legal analysis. Telecoms ombudsman regulatory powers are a category that does not exist. Communications Ombudsman and CISAS are not regulators. Ofcom is the regulator, and the regulator built the cage in which the schemes operate. In our experience advising new entrants on telecoms compliance, the practical confusion is twofold: founders sometimes assume the ombudsman is the body to deal with on regulatory questions and miss Ofcom’s standing role; in-house counsel at established providers sometimes treat ADR participation as the floor of consumer compliance, when in fact the floor is GC C4 and the Approved Code, with ADR as the backstop.
The 8 April 2026 reduction of the trigger period from eight weeks to six is a tightening of the same architecture, not a re-allocation of regulatory power. The next reform worth watching is whether Ofcom moves the ADR schemes’ KPIs and reporting closer to the regulator’s own enforcement priorities, which would make the data trail from complaint to investigation shorter than it is today.
Frequently asked questions
Is a telecoms ombudsman decision legally binding?
Not until the customer accepts it. In both schemes the decision binds nobody on issue: it binds the provider once the complainant accepts, and if the complainant rejects it, or lets the acceptance period lapse, it binds neither side. Under the CISAS rules the decision is binding only if the customer accepts it within thirty working days, acceptance must be of the decision as a whole, and the company then has twenty working days to comply. The Communications Ombudsman membership rules work the same way, obliging a participating company to comply with a final decision the complainant has accepted. Before approving a scheme, Ofcom must be satisfied under section 54(2)(g) of the Communications Act 2003 that awards of compensation can be properly enforced. A complainant who rejects a decision keeps the right to bring a claim in court.
Can you appeal a telecoms ombudsman decision?
It depends which scheme, and the two differ. A CISAS decision cannot be appealed or reviewed: the scheme rules state that the adjudicator’s decision is final, neither party may challenge the adjudicator’s use of its powers, and the scheme’s own complaints procedure cannot be used to attack the outcome. The customer’s only choices are to accept or to reject. The Communications Ombudsman does allow an appeal, in limited circumstances, where new evidence has emerged since the dispute was submitted or a material error has been made; Ofcom records in its July 2025 ADR statement that the Ombudsman’s appeal route is open to consumers and providers alike, while a CISAS decision reached after investigation cannot be appealed. There is no appeal to Ofcom from either scheme. Ofcom approves the schemes under section 54 and keeps them under review, but it does not sit above them on individual complaints. A complainant who rejects the outcome may go to court, and one who thinks the problem is systemic rather than individual can complain to Ofcom, which may open an enforcement investigation under section 96A of the Act.
Does it cost anything to use the telecoms ombudsman?
No. Section 54(2)(c) requires that the arrangements give every domestic and small business customer of a provider the right to use the procedures free of charge. Ofcom cannot approve a scheme that charges them.
What can a telecoms ombudsman award?
Compensation, an apology or a service correction, directed at the individual complainant. Section 54(2)(f) requires the scheme to have power to make awards of appropriate compensation. Both schemes cap an award at 10,000 pounds including VAT, and the cap covers the value of any corrective action as well as money; the Communications Ombudsman reports that typical financial awards run between 50 and 100 pounds. The scheme cannot impose a penalty, change how the provider treats its other customers, or alter Ofcom’s rules.
When can a customer take a complaint to the telecoms ombudsman?
At deadlock, or after six weeks. Under paragraph 11 of the Annex to General Condition C4 the provider must issue an ADR Letter with no waiting period where it has given the customer the outcome of its investigation, the customer has said that outcome does not resolve the complaint, and the provider does not intend to take further steps that would produce a different outcome. Paragraph 12 requires the ADR Letter in any event once six weeks have passed since the complaint was first received. The six-week trigger replaced an eight-week trigger on 8 April 2026, and the change applies only to complaints raised on or after that date.
Who pays for the telecoms ombudsman?
Providers do. The customer pays nothing, because section 54(2)(c) requires the scheme to be free to domestic and small business customers, and both schemes say so in their own rules. Providers fund the schemes through a combination of subscription and per-case fees: the CISAS rules make the company responsible for the scheme’s fees and bar it from suing the customer to recover them, and the Communications Ombudsman membership rules require each participating company to pay such subscriptions and case fees as the scheme sets from time to time. The fee falls whatever the outcome. Ofcom treats that as deliberate: its July 2025 ADR statement records that the cost of a case reaching a scheme gives providers an incentive to improve their own complaints handling, and that shortening the escalation window enhances the incentive to resolve complaints so that providers can avoid ADR case fees. Ofcom put the annual cost of ADR to the main providers at around 3.3 million pounds. Neither scheme publishes its fee scale. The customer still bears their own costs, including legal fees if they choose to be represented.
How long does a telecoms ombudsman case take?
CISAS publishes a timetable and the Communications Ombudsman does not. CISAS assesses an application within fifteen working days, the company has ten working days from notification to respond, and the adjudicator’s decision generally issues within thirty working days of the initial assessment; the scheme’s customer guidance puts the end-to-end expectation at six to eight weeks from acceptance of a completed application. The customer then has thirty working days to accept or reject, and the company twenty working days to comply once acceptance is confirmed. The Communications Ombudsman publishes no equivalent investigation timescale, but requires a provider to implement an accepted resolution within twenty-eight days. Ofcom supervises scheme performance through key performance indicators, which it publishes quarterly, rather than by setting a case clock; it raised the KPI levels in its July 2025 statement, with reporting against the new levels from the fourth quarter of 2025.
