Opensignal: UK 5G download speeds averaged 118.2M Mbps between August 1 and October 29, down 13% YoY, the slowest in the G7 in 2023; France averaged 221.1 Mbps
Context & Ripple Effects
The result puts the UK at the bottom of the G7’s 2023 5G-speed comparison, with France’s measured average providing a clear in-group benchmark. It follows earlier Opensignal evidence that headline 5G availability does not necessarily translate into large performance gains, such as the relatively modest US 5G-to-4G speed uplift.
Speed is only one dimension of network quality: a later G7 mobile-reliability comparison also placed the UK last. Together, the coverage makes the UK’s position a broader network-experience issue rather than a single speed-test anomaly.
First-order effects
- UK 5G users face the weakest average download performance among G7 peers in the measurement period, after a year-over-year decline.
- The result creates an unfavorable performance benchmark for UK mobile operators, particularly against France’s substantially higher measured average.
Second-order effects
- The France comparison raises pressure on UK operators to demonstrate improvement in independently measured network experience, not simply 5G coverage or rollout claims.
- For consumers and business buyers comparing mobile services, network-performance evidence becomes a more salient differentiator among operators and countries.
Third-order effects
- If weak speed and reliability results persist together, mobile-network competition is likely to be judged increasingly on consistent user experience across multiple independent metrics.
- The wider pattern points to a growing gap between nominal 5G deployment and the quality delivered in everyday use, though these measurements alone do not establish its cause.
The trend: 5G competition is shifting from rollout milestones toward independently measured speed, reliability, and overall user experience.
