How do we get our broadband availability data?

Want to know where we get the information about what packages and speeds are available in each area? Here’s an explanation.

By now, you'll have no doubt tried our broadband comparison service - you enter your postcode and it gives you a list of packages available in your area. But how do we get that information?

Where our broadband data comes from

We receive availability information about fibre optic and broadband from each provider. This information is regularly checked and updated, to ensure a high level of accuracy.

When you enter your postcode into our calculator, we compare it against the most up-to-date information we have from each provider. We then list the results to show all your options, and to help you see the overall cost of each.

Since the price of a package can differ significantly depending on where you live, we also ensure providers send us up-to-date, area-specific pricing information - to make sure the package information we display is accurate for each individual user.

How accurate is our fibre optic broadband availability data?

Here at we strive to provide accurate information at all times. However, there may be rare occasions that our results list fibre optic broadband packages that are unavailable at your property.

This is because, in some cases, providers offer fibre optic broadband to some people, but not others, in a single postcode area. In these cases, we still list the packages in our broadband results.

If you're one of the unlucky people in that specific area who doesn't have access to the fibre, providers will tell you if you try to switch to that package - before you sign up.

How accurate is our broadband speeds information?

The speeds we show on our results table are providers' advertised 'average' speeds, rather than speeds specific to your postcode.

Unfortunately, we can't list postcode-specific speed information in our results, as we would need to test each individual line to come up with an accurate figure. However, a provider should allow you to check speeds before you subscribe to their service.

The 'average' speeds we show are based on what 50% of the people with that package can get at peak time (8pm-10pm for residential lines), following advertising rules set in place by the Advertising Standards Agency (ASA) and Committee of Advertising Practice (CAP).

That, of course, means that up to 50% of people might not actually receive the speeds listed, which can seem a little misleading. To counter this, we often speak out in the media about the need for providers to promote more accurate speeds.
