The Non-Domestic Renewable Heat Incentive scheme (NDRHI) is a government environmental programme that provides financial incentives to increase the uptake of renewable heat by businesses, the public sector, and non-profit organisations.

The Northern Ireland Renewable Heat Incentive scheme (NI NDRHI) is the scheme for non-domestic customers in Northern Ireland. The NI NDRHI is administered by the Department for the Economy in NI and is closed to new applicants.

Scheme closure

The Non Domestic Renewable Heat Incentive scheme (NDRHI) closed to new applications on 31 March 2021.

In response to Covid-19, the Department for Energy Security and Net Zero extended the deadline for commissioning for eligible tariff guarantee stage 2, stage 3 and extension applications from 31 March 2022 to 31 March 2023.

This extension was only applicable to applicants who had secured a tariff guarantee or an extension application. 

Who can still apply?

There are some circumstances under which we will require an application for accreditation:

  • Change of ownership – An NDRHI accredited installation has been sold as an ongoing asset to a new owner. A new application is required if the installation has been relocated during the sale. Please see our Change of Ownership (CoO) page for further information.
  • Relocation – If you decide to relocate your NDRHI accredited installation, you must inform us within 28 days of de-commissioning. A new application for accreditation must be submitted once the installation is commissioned at its new location. Please see our Relocations and Replacements page for further information.
  • Replacement – If you need to replace your NDRHI accredited installation, you must inform us within 28 days of de-commissioning the original plant. A new application for accreditation must be submitted once the new installation is commissioned. Please see our Relocations and Replacements page for further information.
