How to read your results
Enter a postcode, then select the address and property reference (UPRN) that match your premises. The report compares the available predictions for all four networks at that selected property. It does not combine nearby properties into one postcode-wide result.
Predictions are a guide, not a guarantee, speed measurement or Ofcom endorsement. Because signal is decided locally, always check the postcode where people actually work rather than relying on a national "best network" claim, and run it again for every other site and home-working address that matters.
For the category definitions, treatment of ties and data source, see how our coverage checker works.
To understand why coverage categories differ between offices, depots and warehouses, read why business mobile coverage varies by location.
For how the networks compare nationally before you check your own sites, see best mobile network coverage UK.
When to use the checker — and when to request an audit
The coverage checker is designed as a fast, self-service first step. It answers the question: how do predicted categories compare at the selected address? But for many businesses, coverage is only part of the decision.
Enter a postcode and select a returned property to compare all four networks at that address.
Request an audit if you have multiple sites, complex usage or want help comparing tariffs and commercial fit alongside coverage.
The checker shows predicted coverage categories; an audit adds contract review, usage analysis and a practical recommendation.
