About Broadband in County Durham
County Durham is a local authority district in England with 267,924 premises in the Ofcom Connected Nations 2025 dataset. Full-fibre (FTTP) broadband is available to 80.6% of premises, and gigabit-capable connectivity reaches 81.9%. Superfast broadband (≥30 Mbit/s) is accessible to 97.7% of premises. County Durham ranks 147th nationally out of 361 local authorities by full-fibre coverage.
The gigabit and full-fibre figures reflect the proportion of addresses that can order an FTTP connection from at least one provider — availability does not imply that every household has taken up a service. Full-fibre take-up across all premises stands at 35%, and among premises where coverage is available the figure is 43%. Ofcom defines gigabit-capable as the ability to receive download speeds of at least 1,000 Mbit/s, which in practice means a full-fibre or qualifying cable network must pass the property.
Some 0.1% of premises remain below the Universal Service Obligation threshold of 10 Mbit/s download / 1 Mbit/s upload, indicating a modest but real connectivity gap for the most remote properties in the area. Fixed wireless access (FWA) is available to 0.8% of premises, providing an alternative to fixed-line broadband for homes and businesses that cannot easily receive FTTP. Figures are drawn from operator network-coverage data submitted to Ofcom and verified through the Connected Nations 2025 methodology. See our methodology page for full details on how premises counts and coverage percentages are calculated.

Coverage Analysis
County Durham's full-fibre coverage of 80.6% places it at rank 147 nationally. The gap between full-fibre availability (80.6%) and gigabit availability (81.9%) reflects whether any qualifying cable networks supplement the FTTP rollout in this district. Where the two figures are close, full-fibre is effectively the sole gigabit delivery mechanism.
Superfast coverage at 97.7% gives a sense of the floor for most residents — the majority of premises in County Durham can receive at least 30 Mbit/s. The USO gap of 0.1% represents premises that cannot yet access the government-mandated minimum of 10 Mbit/s download and 1 Mbit/s upload. In rural local authorities this figure can reach double digits; in dense urban areas it typically approaches zero.
Take-up data provides a demand-side view. With 35% of all premises actively using full-fibre, County Durham gives a clear picture of how quickly residents are switching to future-proof connections as they become available.
