Following the closure of the non-domestic renewable heat incentive (NDRHI) to new applications on 31 March 2021, participants with accredited shared ground loop (SGL) installations (or installations that would become defined as such following modification of capacity) and prospective participants have been, subject to certain conditions, able to modify the capacity of their installations.
Following consultation, on the 21 February 2022 the Secretary of State was given the power to set new budget caps for SGL modified capacity (MC) applications on a sectoral basis; one covering ‘domestic’ applications and another covering ‘other’ applications. A shared ground loop MC budget cap of £4 million was introduced for ‘domestic’ applications and £1 million for applications from ‘other’ sectors for 2022/2023.
This application route for existing and prospective participants closed on 31 March 2023, as required by regulations.
The Secretary of State for the Department for Energy Security and Net Zero has decided that no further budget will be allocated to shared ground loop modified capacity applications.
As part of our administration of the scheme Ofgem publish regular budget updates, to assist participants who have submitted a plan to modify capacity; to understand possible budget take up and allocation. The tables below display the status of the budget information for FY 21/22, 22/23 and 23/24.
Please note that the information in the tables below are not ‘live’ tables; they are a point in time data extract for the modified capacity portfolio. Due to the nature of the portfolio, plans are constantly being submitted and removed from the queue; therefore, the headroom available will change accordingly. We aim to update the tables on weekly basis on a Friday. They will therefore be representative of the portfolio up to midday on the Wednesday before.
