O2 extends 5G Standalone mobile broadband across Derbyshire

By Rebecca Stone

O2 has switched on its 5G Standalone (5G+) mobile broadband network across Derbyshire in England, reaching what the operator says is more than 380,000 people in 368 towns and villages.

O2 described the service as delivering “faster speeds, better coverage and lower latency at no extra cost.” That is a commercial promise, not a measured result: the announcement includes no download or upload figures, latency values or geographic coverage percentages.

What does the Derbyshire rollout include?

O2’s announcement names 20 example locations associated with the deployment. Some had gone live earlier and are only now being confirmed, so the 368-location total should not be read as 368 separate activations on the announcement day.

• Derby
• Chesterfield
• Long Eaton
• Ilkeston
• Swadlincote
• Heanor
• Buxton
• Dronfield
• Belper
• Ripley
• Matlock
• Disley
• Brookfield
• South Normanton
• Shirebrook
• Staveley
• Bolsover
• Somercotes
• Brimington

Bakewell is the conspicuous omission from the announcement. The town received 5G+ coverage in 2025, yet O2 did not include it among the 368 locations announced. That distinction matters because the latest activation list and the broader coverage count are not interchangeable.

The release supplies examples rather than a complete gazetteer. It provides no address-level map, premises count or road-by-road availability for the 368-place footprint. The operator’s population figure therefore establishes the scale of its claim, but not how consistently the service is available within it.

What does 5G Standalone change?

The new service runs on a pure end-to-end 5G architecture. Earlier 5G networks used Non-Standalone (NSA), which partly relied on older, slower 4G infrastructure; the standalone design removes that 4G anchor from the 5G path.

O2 lists ultra-low latency, greater energy efficiency, faster speeds with particular benefit to uploads, network slicing, improved support for IoT devices, and stronger reliability and security. These are technical capabilities associated with the architecture, but the announcement gives no service-level measurements, energy savings or security results against which customers can test them.

The distinction between NSA and standalone 5G is a standards matter with practical consequences. Standalone 5G can allocate network resources independently of a 4G layer, but that architectural advantage does not by itself establish coverage or performance at a particular address.

How does the deployment fit the UK rollout?

O2’s wider 5G+ rollout began in February 2024. The operator says the service is now live for more than 86% of the UK’s population and aims for “at least 90% outdoor coverage” in every location it covers.

Those figures measure different things. The 86% figure concerns people, while the 90% commitment concerns outdoor coverage, although the announcement does not define the geographic unit, testing method or reporting schedule. Population reach can therefore look comprehensive while service remains unavailable on particular streets or in individual premises.

Because the commitment is explicitly about outdoor coverage, it does not establish indoor performance or availability at every address. O2 also provides no deadline for reaching the target, leaving the February 2024 start date as the only broad indication of the programme’s timescale.

What must customers still wait to see?

Access is “typically” available to O2 customers with compatible devices, a qualifier that leaves room for exceptions. More importantly, O2 did not publish town-by-town geographic availability figures for the 5G+ network in this announcement.

For a claim centered on coverage, speed and latency, that is a material gap. A population total cannot show whether the listed towns have continuous outdoor service, whether upload performance differs materially from the earlier 5G layer, or whether network slicing is commercially available. Nor does “at no extra cost” identify any tariff conditions beyond the stated promise.

None of this means standalone 5G lacks technical merit. It means the evidence supplied supports deployment and architectural claims, not a precise account of what any customer in any named location will experience.

The next test for O2 is whether it publishes geographic and performance data as the rollout continues toward its 90% outdoor-coverage target; without a timetable for that evidence, the 86% population figure will remain an incomplete measure of service.
