Methodology
What we measured. For each of the 123towns covered by Switchity's area pages, we recorded the average residential download speed and the cheapest starting price across all broadband deals available at the town's canonical postcode.
Sources.Speeds come from ThinkBroadband Labs' ongoing UK speed-test sample (linked to the relevant labs page from every Switchity town guide). Pricing comes from our live broadband-deal feed via Stickee, the affiliate partner that powers our comparison tools. Both data sources are dated per town — see the source_date column in the CSV.
Exclusions.Towns missing either a measured average speed or a published starting price are filtered out so league tables don't show 0 Mbps or £0. Business-only deals and social tariffs are also excluded; we report the consumer mix that's available to a typical UK household.
Last updated. May 2026. The underlying data refreshes on the same schedule as our individual town pages, so any change at a town level surfaces here within an hour.
