Key takeaways
5G is available in all major UK cities but coverage varies significantly by network and location. EE leads for 5G reach nationally; VodafoneThree has the largest 5G spectrum holding and has committed to 99% population coverage with 5G Standalone.
The UK government's target is nationwide 5G Standalone (5GSA) by 2030, set in DSIT's Statement of Strategic Priorities 2026. 5G Standalone uses a fully 5G core network rather than relying on 4G infrastructure, enabling lower latency and network slicing.
Ofcom tracks 5G coverage through its annual Connected Nations reports and the interim Connected Nations update (January 2026). Coverage figures are based on operator-provided data at 50-metre resolution.
To check whether 5G is available at your address, use Ofcom's Map Your Mobile tool at checker.ofcom.org.uk. The tool shows 5G outdoor and indoor coverage for all four networks at any UK postcode.
5G performance still depends on Ofcom's good performance standard (5 Mbit/s down, 1.5 Mbit/s up, 50ms latency). Having 5G coverage does not guarantee this standard is met -- network congestion, indoor signal loss and handset capability all affect real-world experience.

What 5G is and how it differs from 4G
5G is the fifth generation of mobile network technology. Like 4G before it, 5G uses radio spectrum to connect mobile devices to the internet, but it does so with significantly higher capacity, faster speeds and lower latency than 4G under optimal conditions. 5G networks operate across multiple spectrum bands -- lower bands (sub-1GHz) for wide coverage, mid bands (1-6GHz) for the balance of speed and reach that most 5G customers experience, and millimetre wave (mmWave, above 24GHz) for very high capacity in dense areas.
The key distinction for UK consumers in 2026 is between 5G Non-Standalone (NSA) and 5G Standalone (SA). Most 5G currently deployed in the UK is NSA, meaning the 5G radio is used for data transmission but the underlying network core -- the software infrastructure that manages connections, authentication and routing -- is still the existing 4G core. 5G Standalone uses a fully native 5G core, which enables network slicing (dedicating network resources to specific applications), ultra-low latency, and more reliable connections.
| Feature | 5G NSA (current UK norm) | 5G Standalone (5G SA/5G+) |
|---|---|---|
| Network core | 4G LTE core | Fully native 5G core |
| Latency | 5-30ms typical | 1-4ms possible |
| Network slicing | Not supported | Supported -- enables dedicated network segments |
| Coverage | Widespread in cities | Rolling out 2025-2030 |
| Current availability | EE, O2, Three, Vodafone | EE (5G+), VodafoneThree (rolling out) |
Which networks have 5G in the UK
All four major UK networks offer 5G to customers. Coverage, speed and technology generation vary significantly between them.
EE
EE is the leading 5G network in the UK by coverage and performance. EE launched 5G Standalone -- branded as 5G+ -- and was targeting 41 million people with 5G+ coverage by Spring 2026. EE is owned by BT Group, which has invested heavily in 5G Standalone as its primary competitive differentiator. EE also uses its 5G+ network for fixed wireless access broadband in areas where fibre deployment is limited.
VodafoneThree
The merger of Vodafone UK and Three UK, completed in May 2025, created VodafoneThree -- the UK's largest combined spectrum holder. VodafoneThree has a legally binding commitment to deliver 5G Standalone to 99% of the UK population, made as a condition of the CMA's merger clearance. VodafoneThree's partners Ericsson and Nokia are delivering the 5G SA rollout, described as Europe's largest privately-funded publicly-regulated infrastructure build. Three's 3G network has been shut down, freeing spectrum for 5G deployment.
Virgin Media O2
O2 (consumer brand) offers 5G NSA coverage across major UK cities and towns. The Virgin Media O2 joint venture has invested approximately 700 million pounds in network improvements and strengthened its spectrum portfolio, having acquired 78.8 MHz of spectrum formerly belonging to Vodafone at the time of the VodafoneThree merger. O2's 5G coverage continues to expand but lags EE and VodafoneThree in the Standalone transition.
5G coverage data from Ofcom's Connected Nations
Ofcom's Connected Nations reports are the authoritative source for UK 5G coverage data. The annual report (based on data from July 2025 in the Connected Nations 2025 publication) and the interim update (January 2026 data) provide coverage percentages per operator for outdoor 4G, outdoor 5G, indoor 4G and indoor 5G at premises and geographic area levels.
Coverage data is submitted by operators to Ofcom and modelled at 50-metre grid resolution. The figures represent predicted coverage based on antenna configurations and signal propagation modelling -- not measured performance. Real-world experience may differ due to terrain, building materials, distance from masts and network congestion.
To check 5G coverage at your specific address, use Ofcom's Map Your Mobile tool at checker.ofcom.org.uk. Enter your postcode to see outdoor and indoor 5G coverage for all four networks simultaneously, alongside real-world performance scores based on crowdsourced data.
The UK Government's 5G ambition
The UK Government's Statement of Strategic Priorities 2026, published by DSIT, sets a strategic priority of supporting growth through investment in high-quality 5G networks and maximising access to spectrum. The specific target is nationwide 5G Standalone coverage by 2030. Ofcom's work programme on spectrum, the VodafoneThree Network Commitment, and the Shared Rural Network programme all contribute to this ambition.
The 2030 target is considered achievable but stretching. VodafoneThree's commitment to 99% population 5G SA coverage and EE's ongoing 5G+ expansion are the primary commercial drivers. Government planning reforms (consulted on by DSIT in December 2025) are intended to reduce barriers to mast deployment, particularly in areas where 5G coverage expansion requires new infrastructure.
Spectrum: what powers 5G
Radio spectrum is the essential resource for 5G. Ofcom manages UK spectrum allocation. In 2026, Ofcom awarded more than 5 GHz of millimetre wave spectrum (26GHz and 40GHz bands) for mobile use. mmWave spectrum can deliver very high speeds and capacity in dense urban hotspots -- city centres, transport hubs, stadiums -- but has limited range and poor building penetration. It complements mid-band 5G rather than replacing it.
Ofcom is also developing proposals for the 6GHz band for mobile and Wi-Fi use, and planning release of additional spectrum at 1.4GHz. The 1.4GHz band offers wider coverage area than higher frequencies, making it useful for extending 5G reach into suburban and rural areas.

Frequently asked questions
What is 5G and how fast is it?
5G is the fifth generation of mobile network technology. Real-world 5G speeds in the UK typically range from 100 Mbit/s to 500 Mbit/s on mid-band networks, with peak speeds higher in areas with mmWave deployment. However, real-world performance depends on network congestion, distance from masts, whether your device supports the relevant spectrum bands, and whether you are indoors or outdoors. Ofcom's good performance standard (5 Mbit/s down, 1.5 Mbit/s up, 50ms latency) applies to all mobile networks including 5G.
Which network has the best 5G coverage in the UK in 2026?
EE leads overall 5G coverage and performance in the UK, and is the furthest advanced in deploying 5G Standalone (5G+), targeting 41 million people by Spring 2026. VodafoneThree has the most 5G spectrum and has committed to 99% population 5G Standalone coverage under its CMA merger conditions. Use Ofcom's Map Your Mobile checker at checker.ofcom.org.uk to compare all four networks at your postcode.
What is the difference between 5G and 5G Standalone?
Standard 5G (NSA -- Non-Standalone) uses 5G radio but routes connections through the existing 4G core network. 5G Standalone uses a fully native 5G core, enabling lower latency (as low as 1-4ms), network slicing, and more reliable connections. Most 5G currently available in the UK is NSA. EE's 5G+ and VodafoneThree's rolling SA deployment are the main Standalone networks. The UK Government targets nationwide 5G Standalone by 2030.
When will 5G cover my area?
Use Ofcom's Map Your Mobile tool at checker.ofcom.org.uk to check current 5G availability at your postcode. All four networks are expanding 5G coverage, with urban areas served first and suburban/rural areas following. The UK Government's target is nationwide 5G Standalone by 2030. VodafoneThree has committed to 99% population coverage with 5G Standalone as a legally binding condition of its CMA-approved merger.
Does 5G work indoors?
5G indoor coverage is weaker than outdoor coverage. Higher-frequency 5G (mmWave) has very poor building penetration. Mid-band 5G penetrates buildings better but still loses signal through thick walls, energy-efficient windows and metal building materials. Ofcom's Map Your Mobile shows separate indoor and outdoor 5G coverage predictions. In areas with weak indoor 5G signal, 4G may still be the practical connection your device uses indoors.
Do I need a new phone to use 5G?
Yes. You need a 5G-capable handset to connect to 5G networks. Most smartphones launched since 2020 include 5G support, but entry-level devices may only support certain 5G bands. Check your phone's specifications and your network's list of compatible 5G devices. If your phone supports 5G and you are in a 5G coverage area, your device will connect to 5G automatically -- no settings change required.
Is 5G safe?
Ofcom and the government's advisory body ICNIRP (International Commission on Non-Ionizing Radiation Protection) have confirmed that 5G operates within established radio frequency safety guidelines. Ofcom's spectrum assurance vehicles conduct ongoing signal strength measurements across UK roads. The guidelines are set well below levels at which any harm has been demonstrated. 5G uses the same type of radio waves as existing mobile networks, just at different frequencies and higher capacity.
What is mmWave 5G and where does it work?
Millimetre wave (mmWave) 5G uses very high frequency spectrum (24GHz and above) that can deliver extremely fast speeds but has a very short range and cannot penetrate buildings or obstacles. It is primarily useful in dense urban areas, transport hubs and stadiums where many users are in a small area outdoors. Ofcom awarded more than 5 GHz of mmWave spectrum in 2026. Most everyday 5G use in the UK relies on mid-band spectrum, not mmWave.
