In March 2021, the Government Response to the Future Support for Low Carbon Heat and the Green Gas Levy consultations named Ofgem as the intended administrator of the Green Gas Support Scheme (GGSS) and associated Green Gas Levy (GGL).

The GGSS is intended to encourage the deployment of new anaerobic digestion (AD) biomethane plants, and consequently the proportion of green gas in the gas grid, by providing support to biomethane producers based on the volume of eligible biomethane they inject into the gas grid. The GGSS will be funded through the Green Gas Levy (GGL), which will be placed on all licenced gas suppliers in Great Britain, with the exception of those who supply at least 95% green gas. The GGSS is expected to launch in Autumn 2021, and the first levy payment will be collected during the first quarter of  financial year 2022/23.

Through these two consultations, we are seeking views on our proposed administration of the GGSS and GGL. We encourage respondents to answer the questions that are of most interest.

We are planning to hold two stakeholder engagement events, further details and how to sign up can be found by following the links below:

Sign up for the GGL stakeholder event on 29 July 2021

The closing date for responses is 13 August 2021.To respond to our consultations, please use the relevant template provided below. Use of this template will  help us to process responses more rapidly.  Following analysis of responses, we will publish procedural guidance in phases. Please send your responses to

We are also looking to inform the development of the proposed GGSS and GGL digital services by conducting interviews with biomethane producers and licenced gas suppliers. If you would like to be part of this user research, please send an email to specifying the scheme you are interested in.
