UK Westminster Constituencies, Broadband Coverage
About This Data
This page covers all 650 Westminster parliamentary constituencies across England, Scotland, Wales and Northern Ireland. Each constituency entry shows broadband coverage drawn from Ofcom's Connected Nations Spring 2026 report (January 2026 release, r1), including full-fibre (FTTP), gigabit-capable, superfast (≥30 Mbit/s) and fixed/FWA availability gap (premises unable to receive 10 Mbit/s) figures as a percentage of total premises in the constituency.
Constituency boundaries reflect the 2024 UK general election configuration. Coverage figures represent the proportion of premises that can receive a given service from at least one network operator, they do not indicate actual subscription levels or the speeds households are currently receiving. Constituency-level figures are compiled by Ofcom by aggregating postcode-sector data to constituency boundaries.
Use the filters below to narrow results by nation or starting letter, and the column headers to reorder by any metric. Each constituency links to a detail page with a full breakdown of coverage metrics and nearby comparable constituencies.
