Checked on 26 September 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area. Historic England, the Environment Agency, Natural England and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
