Expert legal insight into UK spectrum regulation and policy

Radio spectrum underpins all modern wireless technologies including mobile, satellite, broadcasting, Wi-Fi, IoT and emerging non-terrestrial networks. This page explains how spectrum is regulated in the United Kingdom under the Wireless Telegraphy Act 2006, the Communications Act 2003 and Ofcom’s statutory duties. It also considers licensing, exemptions, trading, interference management and the UK’s international coordination framework.

This page draws on the UK legislative framework and Ofcom guidance.

Legal framework

UK spectrum regulatory rules are set out in two main statutes:

• The Communications Act 2003 sets Ofcom’s overarching duties, including the obligation to secure optimal use of the electromagnetic spectrum; and
• The Wireless Telegraphy Act 2006 provides Ofcom with detailed licensing, enforcement and administrative powers governing wireless telegraphy apparatus.

Ofcom’s role comprises:

• issuing spectrum licences and granting exemptions;
• managing interference and technical parameters;
• maintaining statutory registers;
• supporting efficient allocation and use through trading and liberalisation;
• advising government on strategic matters including national security;
• participating in international harmonisation processes.

Ofcom must act transparently and proportionately and target regulation only where necessary. These statutory principles govern how Ofcom authorises, monitors and enforces the use of spectrum throughout the UK, Isle of Man and Channel Islands.

Spectrum policy and Government direction

The Government’s 2023 Spectrum Statement sets out the national framework for spectrum management, describing spectrum as a strategic asset essential to growth, innovation, national security and scientific activity.

The six UK policy objectives set out in the Spectrum Statement were:

• promoting efficient and flexible use;
• enabling investment in new wireless services;
• protecting critical national infrastructure;
• supporting defence, space and scientific research;
• strengthening the UK’s international leadership;
• expanding sharing and trading to maximise economic value.

Ofcom’s Spectrum Management Strategy (2022–27) aligns with these aims by promoting shared access, fostering innovation bands, planning for new 5G and 6G harmonisation, and modernising the UK’s frequency planning tools.

Spectrum licensing and authorisation

Unlawful use without a licence

Under s 8 WTA 2006, it is unlawful to establish or use wireless telegraphy apparatus without a licence unless exempt. The definition covers all apparatus emitting or receiving electromagnetic energy below 3,000 GHz, including:

• mobile devices;
• broadcasting equipment;
• radar, GPS, and aviation radios;
• IoT networks;
• microwave links; and
• maritime and aeronautical systems.

Certain categories of equipment may be exempted where use is not likely to cause undue interference or adversely affect technical quality or safety. Typical exemptions cover:

• Wi-Fi and Bluetooth;
• short-range devices;
• RFID and many IoT devices; and
• receive-only equipment.

Ofcom sets the conditions for both licensed and exempt use through registration requirements, power limits, emission masks and safety measures.

Spectrum Licence conditions

Ofcom may impose licence terms governing:

• frequency, power and permitted emissions;
• geographic limitations;
• equipment standards;
• interference management requirements;
• compliance with EMF safety rules;
• obligations to enter roaming or access agreements in specified circumstances.

Conditions must be objective, proportionate, unduly non-discriminatory and transparent.

The UK Plan for Frequency Authorisation

Ofcom publishes the UK Frequency Allocation Table and the UK Plan for Frequency Authorisation (UKPFA). Together these:

• specify allocations for mobile, fixed, satellite, broadcasting and scientific uses;
• detail licence-exempt bands;
• reflect international harmonisation decisions;
• identify the authority responsible for each band;
• support investment planning and lawful operation.

The UKPFA is updated regularly to reflect changes in technology and international policy.

Spectrum trading, leasing and liberalisation

The UK operates a mature secondary market for spectrum trading, introduced in 2004 and subsequently extended:

• holders may transfer their licence rights;
• trading is permitted for most mobile, fixed link and access licences;
• Ofcom’s consent is required for mobile trades involving competition considerations;
• trades must be notified to Ofcom and recorded on the Transfer Notification Register.

Spectrum may also be leased, where permitted under the licence. Leasing allows deployment flexibility without transferring legal title.

Liberalisation policies allow licensees to vary technology and use within defined parameters to promote efficiency and competition.

Shared access and local access licensing

To widen access to spectrum, Ofcom created:

• Shared Access Licences for 3.8–4.2 GHz, 1800 MHz, 2300 MHz, and indoor mmWave bands; and
• Local Access Licences permitting use of spectrum already assigned to national operators but unused in a specified area.

Shared and local licences support:

• industrial 5G networks;
• ports, logistics and construction sites;
• rural broadband applications;
• innovation and testbeds.

Recent reforms broaden spectrum availability, simplify processes and support new use cases such as advanced manufacturing and high-density IoT.

Fees, auctions and market mechanisms

Spectrum may be allocated in the UK through:

• Auctions where demand exceeds supply (e.g. 700 MHz, 3.4–3.8 GHz);
• Administrative Incentive Pricing (AIP) to reflect opportunity cost; and
• Annual Licence Fees for certain mobile bands.

The Wireless Telegraphy (Licence Award) Regulations govern auction processes. Recent trends indicate greater use of administrative and hybrid mechanisms to balance efficiency with innovation objectives.

Interference management and compliance

Ofcom enforces spectrum integrity through:

• nationwide monitoring stations;
• spectrum engineering assessments;
• investigation of interference complaints;
• enforcement notices and penalties;
• seizure powers under WTA 2006.

Operators must comply with licence limitations, equipment conformity requirements and EMF safety obligations, and must eliminate harmful interference upon notification.

Spectrum refarming and release programmes

Spectrum is periodically refarmed to support new technologies. Examples include:

• 800 MHz and 2.6 GHz release for 4G;
• 700 MHz clearance for 5G;
• future mmWave (26 GHz and 40 GHz) planning for 5G/6G;
• public-sector release programmes reallocating government spectrum to commercial use.

These processes require extensive stakeholder engagement, planning and coordination.

International spectrum coordination

The UK participates in global and regional harmonisation through:

• International Telecommunication Union (ITU) – World Radiocommunication Conferences set global allocations;
• CEPT/ECC – European technical frameworks and harmonisation decisions;
• bilateral cross-border coordination with neighbouring states.

International alignment supports device availability, reduces costs and ensures interoperability.

Strategic direction and national security

Whilst Ofcom manages civil spectrum, the Government—through DSIT—retains responsibility for defence and national security matters. Under s 5 WTA 2006, the Secretary of State may direct Ofcom on strategic policy issues.

Spectrum policy must therefore balance:

• commercial efficiency;
• competition;
• innovation;
• national resilience;
• defence requirements.

Emerging trends in UK spectrum management

Key areas of development include:

• enhanced 5G and early 6G ecosystems;
• industrial private networks requiring assured reliability;
• dynamic and database-driven spectrum sharing;
• NTN and satellite broadband expansion;
• use of EHF bands (100–200 GHz) for imaging and ultra-high-capacity links;
• environmental efficiency and net-zero planning.

These developments will drive future amendments to the UK’s spectrum framework.
