NDRHI: Non-Tariff Guarantee Extension Applications Budget Information

The RHI has a limited budget which is set out on the Department for Business, Energy and Industrial Strategy (BEIS) website. Given the limited budget available and the potentially high volume of extension applications submitted, it is important that controls are in place to manage available budget in a responsive and transparent way. As such there is a budget control in place for extension applications.

We publish information to assist applicants that have applied or are thinking about applying for an extension application on the NDRHI scheme. The table below displays the status of the budget control. 

For information about Extension Application, see our Guide to Extension application.

Please note that the information in the table below is not a ‘live’ table; it is a point in time data extract in relation to the Non-TG Extension Application portfolio. 

Due to the nature of the Non-TG Extension Application portfolio, applications are constantly being submitted and removed from the queue; therefore, the headroom available will change accordingly. We aim to update the table on weekly basis on a Friday. It will therefore be representative of the portfolio up to midnight on the previous day.

The figures in the table below are for information only, and should not be used for the purpose of making commercial decisions.



W/GSHPs (<100kWth)

All other non-TG eligible technologies





Budget allocated (based on applications received and extensions granted)




Budget committed (based on extensions granted)



£ 309,534

Remaining headroom available (based on budget allocated)




Based on applications made up to and including the 31 March 2021, there are currently 143 applications being held in the budget queue.  72 in relation to ‘Biomass’ and 71 in relation to ‘All other non-TG eligible technologies’. Applications for the ‘Biomass’ and ‘All other non-TG eligible technologies’ pots will be held in a queue if there is not available budget headroom to accommodate them (if properly made and if eligibility criteria are satisfied), and may be allocated funding if additional budget becomes available.
