What is non-domestic RHI?
The non-domestic Renewable Heat Incentive (RHI), also known as commercial RHI, was launched in November 2011 and is targeted at commercial, not-for-profit, charity and public sector organisations.
The RHI offers annual payments for 20 years to the owners of the equipment, index linked for the heat they generate and use. Combined with the fuel cost savings over fossil fuels, which can be 50% or more, the biomass heating opportunity offers a great return on investment and payback on average of five to six years* (including the cost of finance). Once your biomass installation is accredited by Ofgem, the submission of quarterly heat meter readings determine the quarterly payments that will follow. The RHI tariffs are reviewed every three months and are adjusted on the basis of the increase or decrease in the Consumer Price Index (CPI).
Commercial RHI Legacy: Asset Transfer, Relocation & Compliance Services
- Unlock Remaining Value: RHI Asset Transfer & Relocation
If you are an RHI asset owner looking to upgrade your system, dispose of a boiler, or a buyer looking for a system with a guaranteed income, Treco offers a highly specialised solution: RHI Asset Transfer.
The RHI scheme permits the transfer of ownership (and sometimes relocation) of an accredited biomass boiler. This transforms a used boiler into a income-generating asset.
Why Treco is the UK Market Leader:
- Proven Track Record: We have successfully managed nearly 100 RHI asset transfers and relocations to date, giving us unmatched expertise in navigating Ofgem’s complex compliance and accreditation change process.
- Guaranteed Income: The remaining years on the 20-year contract (index-linked to CPI) are transferred to the new owner, creating a substantial, predictable financial return.
- Protect Your Income: Ongoing RHI Compliance & Support
For all existing RHI participants, securing the next 20 years of payments requires rigorous attention to compliance and maintenance. Failure to meet reporting or technical standards can result in payment suspension or withdrawal of accreditation.
Treco provides comprehensive support packages to ensure your system remains compliant, efficient, and profitable for the full 20-year term.
Our RHI Compliance Services Include:
- Mandatory Audits: Preparation and management of mandatory Ofgem audits, ensuring all documentation (meter readings, fuel logs, maintenance records) is correct and robust.
- Annual Declarations: Assistance with the submission of annual declarations, which are required to continue receiving RHI payments.
- Technical Compliance: Expert maintenance and repair services to ensure your boiler continues to meet all technical standards and efficiency requirements as stipulated by the scheme regulations.
- System Optimisation: Ensuring your system is running at peak efficiency to maximise heat output and, therefore, your financial return.
- New Commercial Biomass Projects
Are you looking to install a new commercial or industrial biomass boiler.
The Non-Domestic Renewable Heat Incentive (RHI) scheme closed to new applications in March 2021, and the Domestic RHI closed in March 2022. While these specific schemes are no longer open to new applicants, non-domestic applications can still benefit from the RHI by acquiring an existing RHI installation that is then transferred over to the new owner. The non-domestic RHI scheme lasts for 20 years from first install, so once ownership is transferred the new owner can benefit from the remaining term that is left. This can be done using either the second hand boiler, or by having a new boiler installed on your site. The rates you get paid vary depending on the size of the original system and when it was installed, though it can be up to 13.62p/kWh (current rates from April 2025 to April 2026). All the current rates for April 2025 to April 2026 can be viewed here. We can advise on any current or emerging UK government support for renewable heating technologies.
