Green Gas Levy draft guidance: For comment


Publication date

Scheme name


An updated version of this guidance was published on 26/1/2022 which supersedes the draft version published for comment on 18/11/2021. 

This draft guidance outlines Ofgem’s administration of the Green Gas Levy (GGL). This includes detail of the obligations for new, current and former licenced gas suppliers. Ofgem's administration of the associated Green Gas Support Scheme (GGSS) is outlined in a separate document to be published shortly.

Please note this version published on 22 November 2021 contains an amendment to Appendix 2: Template letter of credit. The previous version published on 18 November 2021 should be disregarded.

The draft Green Gas Support Scheme Regulations 2021 were laid in September 2021 and are expected to come into force this autumn. We’re releasing procedural guidance in phases and focussing on areas where early insight may be needed.

This draft for comment guidance allows stakeholders to review the proposed guidance and is a ‘live’ document which should be used as guidance on the administration of the GGL until the next phase is published. This is not a consultation on our administrative approach to the policy.

Within this document, we set out what obligations will be placed on suppliers, as well as how to meet them.

These include for each licence suppliers hold:

  • the provision of meter point data
  • lodging of credit cover and
  • making levy payments

It also sets out our supplier compliance framework and the powers Ofgem may use to encourage compliance with the scheme’s requirements. In addition, this guidance clarifies requirements and procedures for exemption from the GGL.  

Suppliers who expect to be provisionally exempt from the levy in 2022/2023 must provide us with notification and evidence relating to this within 10 days of the regulations coming into force.

We have published this document on a draft-for-comment basis to seek views on the clarity and format of this document. On that basis, we’d like to seek feedback on the following questions:

1. The overall tone of the guidance - is the draft guidance easy to read and understand? Are there any sections which could be better explained?

2. Is the draft guidance clear and easy to use?

3. Are there any sections of the draft guidance which are ambiguous?

We are planning to publish an updated version of this guidance early next year, and as such we welcome your suggestions for changes or improvements to this draft guidance by 16 December 2021. Any responses should be sent by email to and clearly identify the related paragraph number.
