The multiplier values
Low (1.0), medium (1.1), high (1.15). The default for any parcel not mapped is medium; the LPA must publish or adopt a mapping for low and high to apply.[S1]
LNRS designation
Local Nature Recovery Strategies are statutory documents under the Environment Act 2021; each responsible authority publishes a mapping of priority areas for nature recovery. Parcels within mapped priority areas qualify for high strategic significance; parcels outside mapped areas remain at medium unless the LPA designates low.[S11]
What the multiplier means for off-site pricing
A habitat bank inside a mapped priority area earns the high strategic significance multiplier, so each hectare it enhances yields more units to sell. Operators do not publish how that feeds into their per-unit quotes.[S1]
Worked example by LPA
Cornwall publishes a comprehensive LNRS with high-significance coastal NCAs; on-site delivery in those NCAs benefits from the 1.15 multiplier. Surrey publishes selectively; Cambridgeshire’s LNRS prioritises chalk stream catchments. Always cross-reference the live LPA-published map; the calculator on this site defaults to medium where no mapping is known.[S12]
