This table gives the prices of statutory biodiversity credits.  

Prices fromare whenbased BNGon the becomescost mandatory.  to create, maintain and monitor different habitat types. There is also a mark-up to prevent statutory credit prices undercutting the off-site market.

Prices will be reviewed every 6 months from when BNG becomes mandatory. We will review pricing to ensure it is set high enough not to compete with the private off-site market, as well as 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. 

Statutory credit prices are not guideline prices for off-site biodiversity units

These prices do not include VAT. You will see VAT in the invoice for any statutory credit purchase. 

You can buy fractions of a credit, if it is rounded to 2 decimal places. For example, 0.5 credits, or 3.76 credits.

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 tool 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 spatial risk multiplier is not accounted for 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.

  1. 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box at top of page to state that biodiversity net gain (BNG) is mandatory from 12 February 2024 and removed the 'draft guidance' label.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'.

  2. 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.

  3. 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.

  4. 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.

  5. First published.
