Windsor Broadband Coverage

Windsor is a Westminster parliamentary constituency in England with 48,114 premises. Full-fibre (FTTP) broadband is available to 74.4% of premises — broadly in line with national trends for a UK constituency. The gigabit-capable figure of 86.9% is typically higher than full-fibre because it includes premises served by upgraded cable (DOCSIS 3.1) networks where a full-fibre connection is not yet available. Superfast broadband (≥30 Mbit/s) covers 97.4% of premises, and ultrafast (≥300 Mbit/s) reaches 87.7%.

On connectivity for all households, fewer than 1% of premises in Windsor fall below the 10 Mbit/s Universal Service Obligation standard, indicating near-universal baseline connectivity. The ge300 column shows coverage at the 300 Mbit/s threshold — 87.7% of premises can access this tier — which is relevant as Ofcom's ultrafast threshold may be revised upward in future reporting cycles as gigabit networks become the standard.

Figures are drawn from Ofcom's Connected Nations 2025 report (July 2025, r01), which aggregates postcode-sector data to constituency level. They represent coverage availability from at least one network operator — not the proportion of households that have subscribed to a given speed tier, nor the typical or guaranteed speeds that customers actually receive.
