My property has an Amber Triangle on it, what does that mean?

In some cases, the information held by the infrastructure providers is incomplete or not up to date, and premises may be shown as unknown.

These are often (but not exclusively) properties that were under construction at the time that the underlying map was created by Ordnance Survey. We are working to address these anomalies.

If your property has an orange triangle on it please contact us at
