Biodiversity Net Gain
Biodiversity Net Gain: Overview
The short version of what Biodiversity Net Gain does and why it exists.
Biodiversity Net Gain created a statutory market for habitat units with a legally secured thirty-year management obligation. This module assesses baseline and uplift using the statutory metric, models the income against the land use given up, manages gain site registration and the legal agreement, and holds the monitoring record for the full commitment period.
Detail
Why Biodiversity Net Gain exists
Biodiversity Net Gain created a statutory market for habitat units with a legally secured thirty-year management obligation. This module assesses baseline and uplift using the statutory metric, models the income against the land use given up, manages gain site registration and the legal agreement, and holds the monitoring record for the full commitment period.
Biodiversity Net Gain became mandatory for major developments from 12 February 2024 and for small sites from 2 April 2024, with a minimum ten per cent gain and habitat secured for thirty years. Natural England operates the Biodiversity Gain Sites Register with a £639 application fee and sells statutory credits deliberately priced to be uncompetitive with the private market, from around £42,000 per credit. Third-party trackers have reported the market at roughly £93 million across 312 registered sites, a figure that comes from commercial sources rather than an official register.
Everything Biodiversity Net Gain records is written into the same platform data spine as every other module, which is why a single entry can satisfy an operational need, a scheme evidence requirement, an assurance clause and a carbon activity line at once. That is the whole design premise: the work is already being done, and it is the recording of it that is duplicated.

In practice
Six things Biodiversity Net Gain changes on day one
None of these requires a new process. They all come from recording the work you already do, once, in a form the rest of the platform can use.

End to end
How Biodiversity Net Gain runs, start to finish
The module is modelled as a state machine, so at any point the business knows exactly which stage every record is at and what has to happen next.
-
1
Assess and record the baseline habitat
This is where the record starts, and getting it right here removes work at every later stage.
-
2
Model creation and enhancement options
The platform prompts only for what this stage genuinely needs, and carries everything forward.
-
3
Calculate units generated
Conflicts with scheme rules, regulatory windows and existing commitments are flagged here rather than discovered later.
-
4
Appraise against the agricultural alternative
Capture works offline, so this stage is completed in the field rather than remembered afterwards.
-
5
Register the gain site
Everything recorded at this point becomes evidence automatically, in every format that will later ask for it.
-
6
Complete the legal agreement
This is the stage most businesses currently do twice, once for the operation and once for the paperwork.
-
7
Create and manage the habitat
Results feed the whole-farm view, so the effect of this stage is visible against the rest of the business.
-
8
Monitor and report for thirty years
The cycle closes here, and what is learned is carried into next season's plan rather than lost.
How we handle evidence
Where these figures come from
Agrivencia grades every figure it publishes. Primary legislation, official statistics and audit reports are treated as authoritative. Levy body and professional body data is treated as reliable. Commercial trackers and trade press are treated as indicative and labelled as such. Where sources conflict, the conflict is shown rather than resolved silently.
- Authoritative Legislation, statutory instruments, official scheme rules, national audit and public accounts reporting, departmental annual reports and accredited official statistics.
- Reliable Parliamentary committee evidence, peer-reviewed research, independent economic institutes and levy body analysis.
- Supporting Professional bodies, land agents, certification schemes and industry associations.
- Indicative Commercial market trackers and trade press, used for corroboration only and always labelled.
Payment rates, caps and windows in UK farm support change frequently and sometimes without notice. Nothing on this platform is a substitute for the current published scheme rules or for professional advice.
