In total, the Crewe Survey consists of 2,000 hectares (4,900 acres), including 165 hectares of woodland, at Crewe and Marbury in Cheshire and other smaller holdings in Cheshire, Derbyshire and Leicestershire.

The estate at Crewe, lying between the town and the M6, was bought in 1936. The Marbury estate, also bought in the twentieth century, lies in the south-west corner of Cheshire. On both estates the main farming activity is dairying, although some arable crops are also grown. These two estates are made up of 20 farms, amenity woodland and let cottages. The Crewe estate is developing for employment purposes on the eastern edge of the town.

In the Peak District, the Duchy’s interests around Castleton include mineral rights over a wide area. These came to the Duchy in 1372.

The South Survey consists of 2,200 hectares (5,436 acres), comprising farmland in Northamptonshire and Lincolnshire, and moorland at Ogmore in South Wales, together with other, lesser properties.

The Higham Ferrers estate in Northamptonshire was part of the original inheritance given by Henry III to his son Edmund in 1266. Today it consists of about 490 hectares, made up of six farms, development land, a golf course and some town cottages.

In South Wales, Ogmore is split into two lordships and extends to 1,530 hectares (3,800 acres) of land, which is mainly subject to rights of common. It includes a golf course and active quarries.
