Tariff Guarantee applications

Guidance

Publication date

Scheme name

Non-Domestic RHI

A tariff guarantee allows applicants to the Non-Domestic Renewable Heat Incentive (RHI) to secure a tariff rate before their installation is commissioned and fully accredited on the RHI. The regulations for tariff guarantees were introduced on 22 May 2018.

Tariff guarantees are available for solid biomass CHP, geothermal and biomethane applications of all sizes, as well as for biomass over 1MWth, biogas over 600kWth and ground source heat pumps and water source heat pumps over 100kWth.

For information about tariff guarantees, see our Guide to Tariff Guarantees on our Main Guidance page.

In order to ensure the RHI scheme stays within budget there are budget controls for tariff guarantees. The budget allocation for tariff guarantees will be set by the Secretary of State and published by the Department for Business, Energy and Industrial Strategy (BEIS).

The below table gives updated information on the status of tariff guarantee applications, and their affect on each year's allocated budget. We aim to update this table weekly.

In relation to TG3, there are 21 applications for 'other' technologies and 4 biomethane applications in the in the TG budget queue; as there is insufficient budget available to allocate to the projects over all of the relevant financial years. Table 4 shows the budget that has been allocated in each of the financial years.

This information represents the queue and granted Tariff Guarantees at the point of publication. It is subject to change based on ongoing queue movement, and should not be used for the purpose of making commercial decisions; it is for information only.
