Change description : 2026-06-02 10:00:00: Updated guidance to show it also applies to nationally significant infrastructure projects (NSIPs). Biodiversity net gain will be mandatory for NSIPs from 2 November 2026. [Guidance and regulation]
Prices are based on the cost to create, maintain and monitor different habitat types. There is also a mark-up to prevent statutory credit prices undercutting the off-site market.
We will review prices every 6 months. Our review is to ensure prices are set high enough to not compete with the private off-site market, as well as being a feasible option for a developer to use as a last resort. We will announce any planned price changes in this guidance, giving at least 10 weeks’ notice.
You can buy fractions of a credit, if it is rounded to 2 decimal places. For example, 0.5 credits, or 3.76 credits.
You can read more about statutory biodiversity credits (this additional guidance only applies to developments that need planning permission).

Information about terms in the table of prices
‘Distinctiveness’ is a measure based on the type of habitat and its distinguishing features. It measures different ecological factors, such as:
the rarity of the habitat
species richness within a habitat
‘Broad’ and ‘specific’ habitat types are terms the biodiversity metric uses to describe different kinds of habitat.
‘Broad habitat type’ describes the general habitat, for example grassland or wetland.
‘Specific habitat type’ describes the habitat in more detail, for example traditional orchards or reedbeds.
The prices in the table are per credit. If you buy statutory biodiversity credits, a ‘spatial risk multiplier’ (SRM) will apply, which doubles the amount of statutory credits you need. The SRM applies to statutory credits to ensure they do not compete with the development of the off-site market and remain a last resort. You must buy 2 statutory credits for every 1 biodiversity unit you need to compensate for. The statutory biodiversity metric tool will automatically calculate this multiplication for you. The SRM is not included in the prices in the table.
For each habitat type in the table, you can see its ‘tier’. Statutory biodiversity credits are priced in tiers according to habitat type for area-based biodiversity units. There are separate prices for hedgerow and watercourse biodiversity units.
Reference to VAT has been removed from the guidance. VAT will not be charged on BNG credits.
12 February 2024
Updated box at top of page to state that biodiversity net gain (BNG) is mandatory from 12 February 2024 and removed the 'draft guidance' label.
Removed 'High, Sparsely vegetated land, Coastal sand dunes'.
29 November 2023
Updated to confirm prices previously published as ‘indicative’, ahead of biodiversity net gain becoming mandatory. The table of prices has not changed. Added detail on price reviews.
11 August 2023
Amended the 'watercourses' table to clarify that there is one tier and price for all types of watercourses. Added information about what we will spend the revenue from credit sales on. Clarified that we have set credit prices high, to ensure they do not compete with the development of the private market. Clarified that prices include all costs, apart from VAT.
2 August 2023
Added an explanation of ‘broad’ and ‘specific’ habitat types to the section 'Information about terms in the table' and re-ordered the information in this section.
