ISPreview is a free editorial broadband checker. UKDataAPI delivers Ofcom data with mobile coverage and scoring via API for developers.
ISPreview is the UK's most popular independent broadband news and comparison site. Its coverage checker lets users enter a postcode to see available broadband speeds and providers — based on Ofcom and Openreach data. It's free, well-maintained, and trusted by consumers comparing broadband options. But ISPreview is an editorial site with a web-based tool, not a data service: there's no API, no mobile coverage data, and no programmatic access. UKDataAPI's Connectivity endpoint returns Ofcom broadband coverage data alongside mobile signal strength from all four UK operators, combined with a proprietary Digital Readiness Score. For developers building property platforms, digital inclusion tools, or connectivity mapping applications, UKDataAPI provides the structured data that ISPreview's checker surfaces for consumers — plus mobile coverage — via API.
