Biodiversity Offsets Scheme Help Desk
Important upcoming changes to BOS Help Desk contact channels
To provide a more efficient and streamlined experience for stakeholders, we’re updating how you access support for the Biodiversity Offsets Scheme.
We’ll be retiring the BOS Help Desk phone and email channels in 2 stages:
- Phone support will close on 24 October 2025.
- Email support will close on 27 February 2026.
Moving forward, the BOS Customer Portal will be your one-stop shop for support. Through the portal, you can:
- track progress in real time – no need to follow up by phone or email
- access helpful resources and frequently asked questions (FAQs) instantly
- submit and manage requests in one place
- get faster resolutions.
We encourage you to begin using the portal now to get familiar with its features and benefits.
