About BNG Quotes

What is on this site

One question, "biodiversity net gain assessment cost", answered with a quote form that works on the page with no account, 4 guides on the questions around it, a data table you can cite (the figures and their method), and the sources every figure rests on.

• Biodiversity net gain cost: assessment fees and delivery cost: BNG cost has two halves: the ecology fee for survey, metric and gain plan, and the cost of delivering the units on site, off site or through statutory credits.
• Biodiversity net gain requirements: what gov.uk actually says: The statutory 10 percent, the biodiversity metric, the biodiversity gain plan and its 8 week determination, the 30 year maintenance period and the delivery hierarchy.
• Biodiversity net gain exemptions: the full gov.uk list for 2026: Which developments are exempt from BNG: the 0.2 hectare threshold from 6 August 2026, the de minimis rule, householder, self-build, temporary and other exemptions.
• BNG units and statutory credits: how the fallback hierarchy prices out: On-site habitat, off-site units and statutory biodiversity credits: how the hierarchy works, the published credit prices, and the 2 credits per unit rule.
