The scheme liable demand is used by Scheme Participants to calculate their individual certificate target under the Peak Demand Reduction Scheme. 

We calculate the scheme liable demand by adding together every Scheme Participant’s individual liable demand for the relevant compliance period (1 November - 31 March).

To calculate the scheme liable demand, we rely on Scheme Participants to report their individual liable demand by 15 October after the relevant compliance period ends. If a Scheme Participant does not report their individual liable demand, we will conduct a default assessment of their individual liable demand.

We will publish the scheme liable demand for the compliance period on this page by 15 December after the relevant compliance period ends, or on a later date that we will specify on this page before 15 November.

We will not amend the scheme liable demand for the compliance period after we have published it.
