The five-minute version
The headline findings from the latest Ofcom data, in plain English. Every figure below is reproducible from the dataset linked in the methodology.
Coverage from at least one network reaches 100% of homes, but only 91% get a signal from all four. The network you pick is the difference.
95% of urban homes get 4G from all four networks against 64% of rural ones. The mobile divide is a rural one.
Tens of thousands of premises, concentrated in rural Scotland, Wales and Northern Ireland, are true not-spots with no indoor 4G from any operator.
Outdoor 5G from all four operators reaches 64% of UK premises. Rollout is far more uneven than 4G, with whole nations and rural areas barely covered.
City of London gets all-network indoor 4G to 100% of homes; Isles of Scilly reaches just 0%.

How the four nations compare
4G and 5G coverage and the share of land with a signal, for each UK nation, with the UK as a reference row. Sort by any metric to surface a different angle.
How the networks compare
Indoor 4G coverage for each network, by nation. The differences are small nationally but matter where you live: pick the network that actually reaches your area.

The UK's mobile not-spots
Coverage from at least one network is now near-universal for homes, but "at least one" is little help if it isn't your network, and whole stretches of countryside still have no signal at all.
homes with no indoor 4G from any network
homes that can't reliably make an indoor call on any network
of the UK's landmass has no 4G signal from any network
The divide is rural. Across the UK, 95% of urban homes get indoor 4G from all four networks, against just 64% of rural ones. For a rural household, the network you choose is often the difference between a working signal and none.

Frequently asked questions about UK mobile coverage
Methodology & sources
What this is. A complete picture of mobile coverage across every UK local authority (361), Westminster constituency (650) and devolved constituency (131), built entirely from Ofcom's own published data. The four mobile network operators report their coverage to Ofcom with a reference date of 1 January 2026 (Connected Nations January 2026).
How coverage is counted. Ofcom reports how many of the four operators cover each home or piece of land. We turn that into three plain measures: "all networks" (signal from all four operators), "at least one" (signal from any operator) and a "not-spot" (signal from none). 4G figures are indoor unless stated; 5G is reported outdoors only.
Per-operator figures.The individual EE, O2, Three and Vodafone numbers are Ofcom's nation-level figures. At local-authority and constituency level Ofcom publishes coverage by number of operators, not by named operator, so the area tables and map show "all networks", "any network" and not-spots rather than a single brand.
5G confidence.We use Ofcom's "high confidence" 5G threshold, its headline measure. A stricter "very high confidence" figure also exists. 3G is excluded as operators complete their 3G switch-off.
Roads.In-car figures are the share of an area's motorway or A-road that has a complete (all-network) 4G signal. Areas with no motorway are excluded from the motorway table.
