Key takeaways
Ofcom -- the Office of Communications -- is the UK's independent regulator for broadband, mobile, landline, television, radio, on-demand video, online safety and postal services. It was created by the Communications Act 2003.
Ofcom replaced five separate regulators: the Broadcasting Standards Commission, the Independent Television Commission, Oftel, the Radio Authority and the Radiocommunications Agency. It became the single communications regulator for the UK.
Ofcom is independent of government but must have regard to the government's Statement of Strategic Priorities. It is funded by licence fees from the broadcasters and telecoms companies it regulates, not by general taxation.
Ofcom's powers include: imposing fines, revoking broadcast licences, managing spectrum, enforcing the Online Safety Act (with fines up to 10% of global turnover), and applying to court for orders to block non-compliant platforms.
Sir Ian Cheshire was appointed Chair of Ofcom in June 2026. Ofcom regulates conduct -- it does not regulate financial services (FCA), data protection (ICO), energy (Ofgem) or advertising standards (ASA).

What Ofcom is and what it does
Ofcom -- the Office of Communications -- is the UK's statutory regulator for the communications industries. It was established by the Communications Act 2003 and took over the functions of five separate regulatory bodies that had previously overseen different parts of the UK's communications landscape. Ofcom's stated purpose is to make communications work for everyone.
Ofcom is an independent public body -- a non-ministerial government department. It is not part of any government ministry and is free to make regulatory decisions without ministerial direction. However, it must have regard to the government's Statement of Strategic Priorities, which is published by the Department for Science, Innovation and Technology (DSIT). The government can set strategic direction; Ofcom decides how to implement it.
What Ofcom replaced
Before Ofcom, UK communications were regulated by a patchwork of separate bodies:
| Former regulator | What it regulated | Replaced by Ofcom in |
|---|---|---|
| Oftel | Telecommunications (BT, telecoms providers) | 2003 |
| Independent Television Commission (ITC) | Commercial television broadcasting | 2003 |
| Radio Authority | Commercial radio broadcasting | 2003 |
| Broadcasting Standards Commission (BSC) | Broadcast content standards and fairness | 2003 |
| Radiocommunications Agency | Radio spectrum management | 2003 |
The consolidation into a single regulator was intended to reduce regulatory fragmentation, improve coordination, and create a single authoritative voice for UK communications regulation. Ofcom inherited the statutory functions, staff and regulatory codes of all five bodies.
What Ofcom regulates
Broadband and mobile
Ofcom regulates all UK providers of broadband, mobile and landline services. This includes setting the General Conditions of Entitlement -- the mandatory rules that all telecoms providers must follow on complaints handling, switching, billing, vulnerable customer protection and number portability. Ofcom monitors compliance and can investigate and fine providers that breach the rules.
Ofcom also manages the UK's National Telephone Numbering Plan, oversees the automatic compensation scheme for broadband and landline faults, and monitors and publishes data on network performance through its Connected Nations reports and Map Your Mobile tool.
Television and radio
Ofcom licenses commercial television and radio broadcasters in the UK. BBC content is regulated by the BBC's own charter and agreement, with Ofcom having a co-regulatory role. Ofcom's Broadcasting Code sets the rules for content across all licensed UK broadcast services -- covering standards on harm and offence, accuracy, due impartiality, fairness, privacy and elections coverage.
Ofcom enforces the listed events regime, which ensures major sporting events are available on free-to-air television. It also regulates video on demand services and the UK's public service broadcasters.
Online safety
Under the Online Safety Act 2023, Ofcom became the UK's online safety regulator. It is responsible for implementing the Act's requirements on user-to-user platforms, search engines and services hosting pornographic content. This includes publishing codes of practice, conducting investigations, and imposing fines of up to 10% of global annual turnover for serious breaches.
Spectrum
Ofcom manages the UK's radio frequency spectrum -- the invisible resource used by mobile phones, Wi-Fi, emergency services, satellite communications, broadcasting and countless other wireless devices. Ofcom awards spectrum licences, runs spectrum auctions, and enforces rules against unlicensed or interfering spectrum use.
Post
Ofcom regulates Royal Mail and ensures the universal postal service -- the obligation to deliver letters to every address in the UK at a uniform price. It monitors Royal Mail's delivery performance and can investigate failures. In June 2026, Ofcom launched an investigation into Royal Mail's 2025/26 delivery performance.
What Ofcom does not regulate
Ofcom's remit is specific to communications. Several areas that people might assume Ofcom covers are actually regulated by different bodies:
| What | Regulated by | Not Ofcom |
|---|---|---|
| Financial services and insurance | FCA (Financial Conduct Authority) | Ofcom has no role in financial regulation |
| Data protection and privacy | ICO (Information Commissioner's Office) | Except where privacy intersects with broadcast content |
| Energy supply | Ofgem (Office of Gas and Electricity Markets) | Even though energy and telecoms bills overlap |
| Advertising and marketing | ASA (Advertising Standards Authority) | Except for broadcast advertising which Clearcast pre-clears |
| Premium rate phone numbers | PSA (Phone-paid Services Authority) | Though Ofcom approves PSA as co-regulator |
| Competition and mergers (general) | CMA (Competition and Markets Authority) | Though Ofcom advises CMA on telecoms mergers |
| Internet content (general) | Ofcom (under OSA) + ICO + police + CMA | Shared jurisdiction depending on the specific issue |
Ofcom's funding and independence
Ofcom is funded primarily through fees paid by the companies it regulates -- broadcast licensees pay licence fees, spectrum holders pay spectrum licence fees, and telecoms providers contribute to Ofcom's costs through industry levies. This means Ofcom is not dependent on annual government appropriations and is insulated from day-to-day political interference.
Ofcom's Board is appointed by the Secretary of State for Science, Innovation and Technology. The Chair and non-executive members are public appointments. The Chief Executive and senior staff are Ofcom employees. Sir Ian Cheshire was appointed as Chair of Ofcom in June 2026, succeeding Lord Grade.
Ofcom's enforcement powers
Ofcom has significant enforcement powers across its regulatory areas. For telecoms providers that breach the General Conditions, Ofcom can issue provisional and final notifications requiring compliance, and impose financial penalties. For broadcasters, Ofcom can issue warnings, impose fines, and revoke broadcast licences in serious cases.
Under the Online Safety Act, Ofcom's enforcement powers are substantial: fines of up to 10% of global annual turnover for the most serious breaches, or 18 million pounds, whichever is higher. Ofcom can also apply to the courts for service restriction orders -- the power to require internet service providers to block access to non-compliant platforms in the UK. Ofcom used its online safety powers to fine a pornography website in both May 2026 and June 2026 for failing to implement age verification.
How Ofcom works with other regulators
Ofcom works closely with other UK regulators where their remits overlap. The CMA and Ofcom have joint roles in overseeing the VodafoneThree merger and its Network Commitment -- Ofcom monitors the network quality improvements while the CMA monitors the consumer tariff protections. The ICO and Ofcom coordinate on privacy questions that arise in the context of broadcasting and online services. Ofcom and Ofgem both interact with the telecoms and energy sectors given the growing convergence between the two.

However, it must have regard to the government's Statement of Strategic Priorities set by DSIT. Its Board members are appointed by the Secretary of State.
How is Ofcom funded?
Ofcom is funded primarily by fees paid by the companies it regulates -- broadcast licence fees, spectrum licence fees and industry levies from telecoms providers. It is not funded by general taxation or direct government grants, which supports its operational independence from day-to-day political control.
What powers does Ofcom have?
Ofcom can: impose fines on broadcasters and telecoms providers; revoke broadcast licences; manage and auction radio spectrum; enforce the Online Safety Act with fines up to 10% of global annual turnover; apply to court for orders to block non-compliant platforms in the UK; issue regulatory codes that industry must follow; investigate complaints and breaches; and publish data on network and service performance.

The Chair and non-executive members are public appointments made by the Secretary of State for Science, Innovation and Technology. The Chief Executive and senior staff are Ofcom employees.
How do I make a complaint to Ofcom?
Ofcom does not investigate individual consumer complaints -- its role is regulatory, not dispute resolution. For individual complaints about broadband, mobile or landline services, use your provider's formal complaints process and then escalate to the Communications Ombudsman or CISAS if unresolved. For complaints about TV or radio content, Ofcom does accept complaints at ofcom.org.uk/make-a-complaint and investigates programmes that may have breached the Broadcasting Code.
