The latest speed tests from Ookla reveal that Three Mobile has emerged as the top performer among the major mobile providers in the UK. Three demonstrated exceptional download speeds, averaging 214Mbps, which is significantly ahead of its competitors. In comparison, this speed is double the average fixed-line broadband speed in the UK.
Vodafone secured the second position in the rankings, followed by EE in third place. On the other hand, O2 lagged behind, offering the slowest speeds overall, according to Ookla’s findings.
Ookla confirmed Three as the Fastest 5G Network in the United Kingdom for Q3–Q4 2025. The Speedtest Award for Fastest Network is based on Speed Score, encompassing download and upload speeds along with latency metrics to evaluate overall speed performance.
Here is a summary of the Ookla results:
– Overall Speed Score:
– Three: 53.46
– Vodafone: 43.05
– EE: 36.73
– O2: 30.70
– Median download speeds:
– Three: 214Mbps
– Vodafone: 129.78Mbps
– EE: 97Mbps
– O2: 78.92Mbps
– Median upload speeds:
– Three: 13.8Mbps
– Vodafone: 10.78Mbps
– EE: 10.96Mbps
– O2: 8.28Mbps
While these results highlight Three’s dominance, it is important to note that evaluating mobile networks can be challenging due to varying user locations and network conditions throughout the day. Despite this, Three’s performance stands out, and there are expectations of further enhancements following its merger with Vodafone.
The newly merged VodafoneThree aims to revolutionize the UK’s mobile network with an £11 billion investment. Through the integration of networks using Multi-Operator Core Network technology, customers of both Vodafone and Three can benefit from improved coverage and performance nationwide at no additional cost.
