# Coverage

> Which areas we cover, which councils' registers we read, and what low confidence means.

## England only

We cover all of England. Scotland, Wales and Northern Ireland have different planning systems and aren't covered yet. A search outside England tells you so.

## What every field gets

Every field in England is checked against the same national data:

* protected wildlife sites, ancient woodland and battlefields
* flood zones
* Green Belt, National Parks and National Landscapes
* farmland quality
* how close it is to a town or village
* road access
* schools, GP surgeries and public transport
* public rights of way

See [Data sources](https://docs.checkthatfield.com/concepts/data-sources.md) for where each comes from.

## What depends on the council

Some checks depend on what each council publishes. The first two find the strongest signs of development:

* **Local Plan allocations and sites put forward**, from the council's published plans and maps.
* **Planning applications on and near the field**, from the council's planning register.
* **The council's housing supply and Local Plan age**, from council statements and the Housing Delivery Test.

Within England we don't yet read every council's planning register. We read over 130 councils' registers every day; for the rest, reports rely on national data. The [councils pages](https://www.checkthatfield.com/councils) list every planning authority in England, with the applications we hold, applications for new homes in the last year, its Local Plan sites and its housing land supply.

> For today's numbers (councils read, applications held, fields scored), see the [public metrics](https://docs.checkthatfield.com/api/public-metrics.md).

## Confidence

Every report says how confident its score is: high, medium or low. It lists each check and whether it was made.

> [accordion] Low confidence
>
> We don't yet hold the council's Local Plan sites or its planning applications for that area. Without them the score may be missing something. The report says which checks it couldn't make.

> [accordion] Medium confidence
>
> Some checks are partial or still under way: for example, we're still reading back through a council's register, or the deep report's web check hasn't been run.

> [accordion] High confidence
>
> Every check was made in full, including the web check.

The report's **Data and sources** tab shows the checks one by one, and **What we could not check** lists the gaps.
