The Ferals supplies off-site Biodiversity Net Gain units to developments across Wiltshire — and south Wiltshire shares our Cranborne Chase National Character Area, keeping spatial risk low.
The Ferals lies within the Cranborne Chase National Character Area (NCA 134), which extends north across the Dorset border into south Wiltshire. Developments around Salisbury, Tisbury, Mere and the southern Wiltshire downs often share this landscape character — an advantage under the BNG spatial risk framework, since units delivered in the same National Character Area as the development carry no spatial risk penalty.
As a registered biodiversity gain site on the Natural England register (reference BGS-180925001), we provide fully compliant off-site units backed by a 30-year Section 106 agreement. Units are available now.
Salisbury, Tisbury, Mere and the southern downs may share the Cranborne Chase NCA with The Ferals — potentially no spatial risk penalty. We confirm from your metric.
Warminster, Westbury and Trowbridge area. Standard spatial risk multiplier applies for developments outside the shared NCA.
Chippenham, Calne and Melksham. Neighbouring county supply with standard spatial risk multiplier applied.
Swindon Borough developments. Available subject to spatial risk assessment for your site.
Under the statutory biodiversity metric, off-site units delivered in the same National Character Area or Local Planning Authority as the development carry no spatial risk multiplier; units in a neighbouring area carry a 0.75 multiplier; and units elsewhere in England carry a 0.5 multiplier. Because the Cranborne Chase NCA straddles the Dorset–Wiltshire border, some south Wiltshire developments can source units from The Ferals with no penalty at all. Send us your metric and we will confirm which multiplier applies to your site.
Not every development can deliver its full 10% biodiversity net gain on site. Common reasons developers need off-site BNG units include:
The Ferals currently offers four habitat unit types, all verified under the statutory Biodiversity Metric:

Yes. The Ferals supplies off-site BNG units to developments across Wiltshire. South Wiltshire developments around Salisbury may share the Cranborne Chase National Character Area with our habitat bank, which can mean no spatial risk penalty. For north Wiltshire, such as Chippenham and Swindon, a standard neighbouring-area multiplier applies.
Yes, potentially. The Ferals sits within the Cranborne Chase National Character Area (NCA 134), which extends north into south Wiltshire around Salisbury, Tisbury and Mere. Developments within the same NCA carry no spatial risk penalty. We confirm this from your development's biodiversity metric.
It depends on location. Units delivered in the same NCA or authority as the development carry no multiplier; neighbouring areas carry a 0.75 multiplier; elsewhere in England carries a 0.5 multiplier. Some south Wiltshire sites qualify for no penalty via the shared Cranborne Chase NCA. We calculate the exact figure for each development.
