• In a UK first, BT’s networks have been independently proven to deliver the nation’s best mobile and broadband connectivity at the same time.

• In a nationwide study analysing the performance of all major broadband providers, Ookla found the Full Fibre network that delivers both BT and EE broadband to be the best in the UK – producing the fastest real-world speeds and highest-quality gaming experience.

• At the same time, RootMetrics® found EE – part of the BT family – retains its crown as the UK’s best mobile network for a record-extending 13^th year in a row.

• Consumer and Business customers of both brands are benefiting from BT’s £40 billion investment into the UK this decade, with Full Fibre and 5G+ being rolled out to millions more people, homes, and businesses.

LONDON: The results of two major studies analysing mobile and broadband network performance across the UK have been revealed, with BT and EE providing the best connectivity both in and out of the home – benefitting millions of people, communities, and businesses in every part of the country.

More than 104 million individual tests were completed across the two studies, measuring broadband and mobile performance in towns, cities and rural communities in the UK, including at peak times when all networks are under the most pressure.

The results mark a UK first, with BT’s networks being independently proven to deliver both the nation’s best performing broadband and mobile connectivity at the same time.

The findings come as research shows more than three quarters of people in the UK (77%) feel isolated from friends, family and critical online services when they don’t have effective internet connectivity. ¹ With more of daily life now dependent on reliable broadband and mobile coverage, the in-depth testing provides consumers and businesses with a clear view of which networks deliver the best real-world connectivity to meet their needs.

Backed by BT’s £40 billion investment into the UK this decade, which will see its Full Fibre and EE’s 5G+ network rolled out to millions more people, homes, and businesses, this record-breaking network performance has been achieved in the face of intense competition in both the broadband and mobile markets.

Greg McCall, Chief Security and Networks Officer at BT, said: “These landmark studies are powerful proof that our investment in improving the UK’s connectivity continues to deliver where it matters most – for families, businesses, and emergency services across the nation.

“Whether you’re at home, at work or on the move, resilient and reliable connectivity is essential to how we live our lives, powering the economy and shaping how we work, learn, keep entertained and stay safe. That’s why we’re bringing Full Fibre and 5G+ to millions more homes, communities, and businesses – so more people can benefit from accessing faster, stronger and more secure connectivity on the UK’s best networks.”

Backing Britain with the UK’s best broadband

The first study by Ookla evaluated the performance of UK broadband networks to understand which major providers are delivering exceptional connectivity to their customers. Using crowdsourced data direct from users across the UK, Ookla generated an overall connectivity score for each operator, which consists of real-world network performance in several important areas, including speed, latency, web browsing, video streaming and gaming – including at peak times.

The results found that BT’s Full Fibre network, which powers the broadband experiences for both EE and BT customers, delivers:

• The UK’s best broadband, winning the award for the first time and proving EE and BT customers are getting the highest-quality broadband performance.

• The UK’s fastest broadband, recording the highest peak download speeds of any major provider and highest average upload speeds.

• The UK’s best broadband gaming experience. EE and BT customers in Cardiff, Glasgow, Edinburgh, Leeds, Sheffield and Nottingham are among those getting the most responsive gaming performance with the lowest jitter. ²

BT’s network division has long been a pioneer in fixed connectivity, consistently improving performance for both BT and EE broadband customers. From launching the UK’s first nationwide Wi-Fi 7 service to bringing 8Gbps speeds to market on next-generation XGSPON broadband, in recent months its fixed network has been optimised for smarter in-home coverage and more reliable streaming, working and gaming, with new tools such as Wi-Fi Intelligence, Wi-Fi Optimiser and Cyber Threat Protect made available to give customers faster, stronger and safer connections.

The total number of customer connections to BT’s Full Fibre network has increased by 16% since the start of 2026, as more households and businesses rely on it to power their lives, workforces and critical operations. ³

Connecting communities with the UK’s best mobile network

A second separate study by RootMetrics® – one of the longest running in the UK which takes six months to complete – saw a team of independent analysts travel around the country examining mobile performance in real-life situations, completing 609,000 tests in a variety of locations and scenarios using shop-brought smartphones and SIMs.

Designed to reflect real customer behaviour, the testing covered the UK’s largest 16 cities, rural communities in each of the four nations, as well as 21,800 miles of roads, 722 indoor locations, and areas of high and low network congestion.

The results found that:

• Overall, EE provides the most reliable mobile connectivity in more places than anyone else, naming it the UK’s best mobile network for a record-extending 13 years in a row.

• EE has improved its performance in the last six months, now providing the best and fastest mobile connectivity in all 16 of the UK’s largest cities, including Belfast, Birmingham, Bristol, Cardiff, Coventry, Edinburgh, Glasgow, Leeds, Leicester, Liverpool, London, Manchester, Newcastle, Nottingham, Sheffield, and Southampton.

• EE continues to deliver the UK’s best 5G experience with the most 5G availability and the highest average 5G download speeds (230.8 Mbps), which are nearly twice as fast as Virgin Media O2 and more than 32% faster than Vodafone.

• EE provides the UK’s best mobile connectivity for video streaming, having improved its overall video performance in the last six months.

• EE customers also benefit from the best and most reliable gaming experience on any UK mobile network, with its low latency making gaming on the move smooth and more responsive. ⁴

Recent months have seen several major improvements made to the EE mobile network, so consumers, businesses, and critical national services continue to benefit from greater reliability, faster speeds, and a more secure mobile experience wherever they are.

These upgrades include expanding 5G+ coverage to a further six million people since January, upgrading the spectrum on 9,000 mobile sites to boost 5G and 5G+ performance, being the first to deliver reliable mobile signal to rural communities like those in Penmachno, Clocaenog, and Islay, as well as rolling out pioneering innovations such as Advanced RAN Coordination (ARC), which is improving EE’s mobile performance by up to 20% on average in the UK's busiest cities, including London, Glasgow, Liverpool, Manchester, Cardiff and Newcastle.
