BNG SEARCH GUIDE · UPDATED 26 JULY 2026

A practical guide for land, planning and unit decisions.

01

Do not buy only a number

A unit should come with evidence: habitat type, location, metric output, legal security, HMMP and allocation route.

02

Check local fit

Units closer to the development and relevant to the local strategy can be more useful than distant generic supply.

03

Understand timing

Planning programmes need units available at the right time, not only in principle.

04

Check delivery risk

Creation difficulty, time to target condition and management obligations affect credibility.

05

Use register evidence

The Natural England register and allocation evidence should be checked when relevant.

06

Engage early

Early matching between developments and gain sites reduces planning risk and unit scarcity.
