What is verification?

Verification is the ongoing evaluation of the project against the requirements of the Woodland Carbon Code.   

Verifications are carried out by organisations which have been approved by the UK Accreditation Service. Verifiers check claims about actual carbon capture are accurate and that the project continues to be well managed. Projects are verified to a reasonable level of assurance, except at year five, where it’s a limited level of assurance. 

When do I verify and how long does it take?

Your first verification should be complete five years after the project start date.  

After this, you should verify your project at least every ten years, unless you choose to self-assess instead.  

You can find the due date on your latest validation or verification statement. Verification dates are linked to the vintage end dates of your units.  

It’s best to start planning your monitoring and verification at least 18 months before the verification is due.

Once you have submitted your verification documents, it may take 12 months for your verification to be completed.

You can contact us to request a verification extension if there are extenuating circumstances.

Verifying groups of projects

Most groups are formed before validation, but you can also create a group for verification. If you do this:

  • The start dates of the projects should be within two years of each other so their verifications are due within two years of each other.
  • The verification due date for the group will be the latest of the individual project verification due dates. Contact us to arrange extensions for the projects in the group with earlier verification due dates.
  • You need a group manager and group agreement (see 2.1 commitment of landowners and project/ group managers).
  • The grouping should remain the same for each subsequent verification.

How much does verification cost?

The cost of verification varies because each third-party verifier sets their own fees. We recommend getting quotes from both verifiers.  As of April 2025, the cost of third-party verification is £1,800 to £3,500 plus VAT per project.

The cost of verifying a group will be higher, but the cost per project will be lower. For example, the cost per project could be £370 to £1,820 plus VAT depending on the size of the group.   

There may be extra costs for travel and subsistence if any site visits are required.

If you have hired a project developer, they might charge you for their time to survey your woodland, complete your verification documents and work with the verifier on your behalf. Be sure to discuss this with them.

When your project is verified, Pending Issuance Units are converted to Woodland Carbon Units. There is a minimum fee of £100 for this.  

  • Converting Pending Issuance Units to Woodland Carbon Units costs 10 pence per unit.  
  • Projects may issue extra units at verification if they’ve removed more carbon than expected or didn’t issue Pending Issuance Units at validation. Issuing extra units costs 15 pence per unit. 

If the total unit costs are less than £100, you will be charged £100. If the total unit costs are more than £100, you will be charged the unit costs. Visit the registry fees page for more details.
