England is divided into 159 'National Character Areas' (NCAs), which government body Natural England describe as 'distinctive' large-scale units of landscape with 'a unique "sense of place".' They provide the 'broad divisions...on which strategies for both ecological and landscape issues can be based.' (Source: Natural England)

In the context of Biodiversity Net Gain, NCAs are one of two geographic measures by which the appropriate "Spatial Modifier" for a purchase of units can be calculated (the other being LPA boundaries). The "Spatial Modifier" affects how many units you need to purchase from a given gain site, in order to achieve a certain number of units on your own site.

As such, providing your development's NCA can sometimes enable us to find you a better price for the units you need, because for each possible source of supply you may gain a more favourable Spatial Risk Modifier.
