How we built this
No single source can describe the UK broadband market accurately. We combine four.
Companies House API
Legal names, numbers and corporate trees from the official register.
Web-health monitoring
Automated checks on DNS, TLS and HTTP for every URL we list.
Heuristic geocoding
Postcodes mapped to UK ITL1 regions for consistent geography.
Human sample review
Every flagged row, ambiguous ownership chain and edge case is reviewed by a person.
Monthly snapshot discipline
Every snapshot is dated, versioned and compared to the last so drift is visible.
Confidence rating
71/100
Average across 595 active providers
We score every provider on four axes and average across the active index. Higher scores mean we know more, and know it more reliably.
313 High 52.6%
88 Medium 14.8%
45 Basic 7.6%
149 Low 25%
Our quarterly target: we commit to raising the index-wide average by at least 1 point per quarter. Next target: 72 by 30 September 2026.

Every month we reconcile new Companies House filings, verify dead links, chase down ownership changes, and review reader corrections. The numbers above are a public commitment.

What we know, field by field. This is our self-criticism: the gaps are where we have more work to do.
Website health
Some big providers actively block automated HTTP probes. "Bot-blocked" does not mean the website is broken; it means they have told our crawler to go away politely.

Monthly snapshot commitment
A fresh snapshot every month, always. Each one is versioned and preserved so researchers and journalists can cite a stable point-in-time record. We hold ourselves to a minimum one-point confidence improvement per quarter, and we would rather miss a headline number than fudge one.
Dataset access for researchers and journalists
The full row-level CSV is not published as a bulk download. If you need it for legitimate research, policy work or reporting, email hello@searchswitchsave.com with a short description of your project and how you will use the data.

Data discrepancies may exist. The UK broadband market is large and moves quickly. Our corrections queue is the fastest way we fix things.
