UK ends small-scale biomass generator subsidies
The UK government has confirmed it will not extend financial subsidies for small-scale biomass electricity generators once existing support schemes conclude. This decision marks a significant policy shift, impacting smaller operations that have relied on government funding for their biomass power production. The move suggests a re-evaluation of the UK's approach to supporting various renewable energy technologies and could influence future investment and development in the small-scale bioenergy sector, as reported by Biomass Magazine1.

Understanding the UK biomass subsidy landscape
The UK's approach to renewable energy support has evolved considerably, with biomass playing a varied role. Historically, government incentives aimed to encourage the adoption of renewable technologies to meet decarbonisation targets.
Historical context of biomass support
For years, biomass energy, derived from organic matter, received government backing through schemes like the Renewables Obligation (RO). These subsidies aimed to make biomass a more financially attractive option for both heat and electricity generation, contributing to the UK's renewable energy mix. The RO scheme, for instance, supported both large and small-scale biomass power generators.
Key distinctions: heating vs electricity generation
It is crucial to distinguish between support for biomass heating and biomass electricity generation, as policy changes have affected these sectors differently. While both have received subsidies, recent government decisions primarily concern electricity generation, particularly from small-scale plants.
The end of small-scale biomass electricity subsidies
The UK government has made a clear decision regarding future financial support for smaller biomass electricity producers.
Government policy shift explained
The UK government has officially stated its intention not to extend financial subsidies for small-scale biomass generators when the current RO scheme expires. This scheme supports various renewable technologies, including biomass. The government's position is that continued backing for these assets does not represent value for money for billpayers, given their relative cost and contribution to the power system.
What is the RO scheme?
The RO was a key government support mechanism for large-scale renewable electricity generation in the UK. It placed an obligation on electricity suppliers to source a specified proportion of their electricity from eligible renewable sources. The scheme closed to new generating capacity in March 2017, but existing accredited generators continue to receive support.
Impact on small-scale generators and businesses
The decision means that small-scale biomass facilities will not receive transitional support after their existing RO support ends. This support will begin to expire from 2027 onwards, with different assets reaching the end of their support periods at various points through to 2037. Industry groups have expressed concerns that the move could lead to plant closures and disrupt waste wood processing. The loss of secured revenue streams could render some smaller installations uneconomic.
Transitional arrangements for larger projects
While small-scale biomass generators face the withdrawal of subsidies, the UK government has indicated it will provide transitional support to large-scale biomass generators after the RO scheme expires. This distinction highlights a strategic prioritisation within the government's energy policy, focusing support on larger projects that may offer different economic or strategic benefits.
The renewable heat incentive (RHI) scheme's legacy
The RHI was a significant scheme supporting renewable heating technologies, including biomass boilers.
What was the RHI and how did it work?
The RHI was a government financial incentive designed to encourage the uptake of renewable heat technologies in homes and businesses across Great Britain. It provided quarterly payments to participants over seven years for domestic installations, based on the amount of clean heat produced. The scheme covered various technologies, including biomass boilers, heat pumps, and solar thermal systems.
When did the domestic RHI close?
The domestic RHI scheme closed to new applications at midnight on 31 March 2022. Those who successfully applied before this date continue to receive payments for the remainder of their seven-year term, provided they meet ongoing obligations.
What replaced the RHI for heating?
Following the closure of the domestic RHI, the Boiler Upgrade Scheme (BUS) was introduced to support the deployment of low-carbon heating technologies in England and Wales. You can find more information about this in our BUS explained article.
Alternative renewable energy support for UK property owners
With the cessation of many biomass-specific subsidies, property owners now need to look at alternative government support for renewable energy solutions.
The Boiler Upgrade Scheme (BUS)
The BUS offers upfront capital grants to help property owners in England and Wales replace existing fossil fuel heating systems with more efficient, low-carbon alternatives. This includes grants for air source heat pumps (£7,500) and ground source heat pumps (£7,500) .
Eligibility for biomass boilers under the BUS is restricted to specific circumstances, such as rural locations not connected to the gas grid, and properties must meet high emissions standards to mitigate air quality impacts.
Other grants and incentives for low-carbon heating
Beyond the BUS, property owners may find other regional or local grants for energy efficiency improvements and renewable heating. It is always advisable to check with local authorities or energy advice services for the most up-to-date information on available support.
Support for solar panels and battery storage
While direct subsidies for small-scale biomass electricity generation are ending, other renewable technologies continue to receive support. Solar panels and battery storage systems can benefit from schemes like the Smart Export Guarantee (SEG), which ensures homeowners receive payments for electricity they export to the grid. Investing in these technologies can offer long-term savings and contribute to energy independence. Learn more about how you can benefit from exporting energy in our guide to the SEG.
Future outlook for biomass in the UK
The role of biomass in the UK's energy strategy is evolving, with a focus on sustainability and specific applications.
The role of biomass in decarbonisation
The UK government published its Biomass Strategy in August 2023, outlining the significant role it believes biomass can play in achieving net zero by 2050. The strategy emphasises strengthening biomass sustainability and prioritising its use in sectors where it can deliver the most benefit, particularly when combined with carbon capture and storage (BECCS) to achieve negative emissions. Biomass contributed to the UK's energy supply in 2022, predominantly for electricity generation, biofuels, and domestic heating.
Challenges and opportunities for the biomass industry
The biomass industry faces challenges, particularly for small-scale electricity generators adapting to a subsidy-free market. Concerns have been raised about the impact on waste wood management and the economic viability of some plants. However, opportunities remain in areas aligned with the government's Biomass Strategy, such as sustainable sourcing, bioenergy with carbon capture, and specific roles in hard-to-decarbonise sectors.
Making informed decisions for your energy future
For property owners, understanding these policy shifts is crucial. While direct financial support for small-scale biomass electricity is ending, and biomass heating subsidies are more restricted, a range of other renewable energy options and support schemes are available. Evaluating the long-term financial viability of any energy system without direct government subsidies, and considering alternative low-carbon technologies like heat pumps and solar, is essential for making informed decisions about your energy future.
