Quick Tips

Jump-start your understanding with these essential tips

A cheaper deal is not always better. If speed is much lower, you may still get poor value. Check both price and likely real speed.

Broadband can change street by street. Your postcode gives a much better picture than a national advert.

For calls, uploads, and streaming, a steady connection is often more important than a high “up to” speed on paper.

Step-by-Step Guide

Follow these steps to get the most from this tool

This loads local data for your area. You can also add your current monthly bill and speed if you want a direct comparison.

We compare advertised speed with likely real speed. This helps you spot deals that look good in ads but may feel slower in real life.

Use value score (speed per £) to rank deals. Then pick options that meet your minimum speed needs.

Advanced Topics

Deep dives for advanced users

Even in the same town, speeds can vary a lot. That is why postcode checks are more useful than general claims.

Value score is speed-per-pound, adjusted by complaints risk when Ofcom complaints data is available.

Reliability index combines speed percentile, coverage, and complaints context into one easy score.

Future readiness combines FTTP availability, FTTP take-up, and technology coverage so you can see long-term broadband quality.

Use this tool to shortlist deals, then check contract length, setup fees, and price rises on the provider website before you switch.
