What Tax Incentives Are Available for UK Green Energy Startups in 2023?

March 7, 2024

In the quest to combat climate change and transition to a sustainable low-carbon future, governments globally are increasingly recognising the vital role of green energy businesses. For the United Kingdom, the impetus to support these innovative startups is high, particularly in the wake of Brexit. Various tax incentives have been put in place to attract investment and stimulate growth within this sector. This article dives deep into the tax benefits that were available for UK green energy startups last year in 2023.

Enterprise Investment Scheme (EIS)

The UK government, in its quest to encourage private investment in startups, initiated the Enterprise Investment Scheme (EIS). EIS is designed to help smaller high-risk trading companies raise finance by offering tax reliefs to investors who purchase new shares in these companies.

The scheme provides attractive tax benefits for investors, therefore, making startups particularly appealing. For instance, it allows investors to claim up to 30% of the cost of investment as income tax relief, thus reducing the net investment cost. Furthermore, if the investment is successful, any gain is free from capital gains tax. This has the dual benefit of not only providing green energy startups with much-needed capital but also encourages private individuals to support these businesses.

Research and Development (R&D) Tax Credits

Equally significant to green energy startups is the government’s R&D tax credit scheme. The purpose of this policy is to encourage businesses across all sectors, including green energy, to invest in R&D. The government recognises that innovation is the key to achieving net-zero emissions and addressing climate challenges. Therefore, businesses that spend capital developing new products, processes or services, or enhancing existing ones, can claim R&D tax relief.

This tax incentive can be exceptionally beneficial for green energy startups, many of which are heavily involved in R&D activities as they seek to innovate and disrupt traditional energy markets. These businesses can recoup up to 33% of their qualifying R&D expenditure, a substantial financial boost that can be reinvested back into their research efforts.

Capital Allowances on Green Technology

Green energy startups can also benefit from capital allowances on green technology. The UK government provides these allowances to incentivise businesses to invest in energy and water-efficient equipment. This scheme supports the acquisition of numerous green technologies, including energy-saving lighting, heat pumps, and gas refitting systems, to name a few.

When green energy startups invest in such equipment, they can claim a capital allowance, effectively deducting the full cost of the asset from their profits before tax. This significantly reduces the net cost of investing in green technology, enabling these businesses to enhance their green credentials while also improving their bottom line.

Social Investment Tax Relief (SITR)

Social Investment Tax Relief (SITR) is another tax incentive that green energy startups may be eligible for. Introduced in 2014, SITR aims to encourage individuals to support social enterprises by providing a 30% income tax relief for investments.

The UK government recognises that many green energy businesses are not only profit-driven but also have a social mission: to combat climate change. Consequently, these businesses may qualify as social enterprises, and their investors may be eligible for SITR. This further widens the pool of potential investors for green energy startups and enhances their ability to attract crucial capital.

Carbon Pricing

Lastly, the UK government’s carbon pricing mechanism indirectly serves as a tax incentive for green energy businesses. This policy requires businesses that produce considerable greenhouse gas emissions to pay a cost that reflects the environmental damage they cause.

Although this is not a direct tax benefit for green energy startups, it does level the playing field by making fossil fuel energy more expensive compared to green energy. This stimulates demand for green energy solutions, thus indirectly benefiting green energy startups through increased business opportunities.

By offering these tax incentives, the UK government has reaffirmed its commitment to stimulating the green energy sector. Through the EIS, R&D tax credits, capital allowances on green technology, SITR, and carbon pricing, it has created a conducive environment for green energy startups to thrive while playing a vital role in achieving the country’s net-zero emissions target.

Seed Enterprise Investment Scheme (SEIS)

In support of small, early-stage companies, the UK government initiated the Seed Enterprise Investment Scheme (SEIS). This scheme specifically targets startups in their infancy, offering attractive tax reliefs to investors who are willing to back these businesses. SEIS has been a boon for green energy startups that often face difficulties in securing funding due to their high-risk nature.

Similar to EIS, SEIS offers tax reliefs to investors. However, the reliefs under SEIS are more substantial given the higher risk associated with investing in early-stage startups. Investors can claim up to 50% of their investment as income tax relief under SEIS, compared to 30% under EIS. Furthermore, if a startup fails, investors can claim loss relief, which further reduces the financial risk involved.

SEIS also includes a capital gains tax exemption for any gains made on the investment if it is held for at least three years. Additionally, there is a capital gains tax reinvestment relief which allows investors to defer capital gains tax on other assets by reinvesting the gain in qualifying SEIS companies.

This encourages more investors to pump capital into green energy startups at an early stage, thus helping these businesses to develop innovative renewable energy solutions and contribute towards the UK’s climate change goals.

Enhanced Capital Allowances (ECA)

The UK government has also introduced Enhanced Capital Allowances (ECA) to incentivize businesses to invest in energy-efficient and water-saving equipment. These are an extension of the aforementioned capital allowances on green technology, with ECAs offering 100% first-year allowances for investments in certain energy and water-efficient equipment.

The primary difference between ECAs and regular capital allowances is that ECAs allow businesses to write off the whole cost of the asset against taxable profits in the year of purchase. This means that green energy startups can reduce their tax bill and recoup the cost of investment much quicker, thus improving cash flow.

ECAs cover a wide range of technologies, including energy-saving boilers, energy management systems, and water conservation equipment. These tax incentives are instrumental for green energy startups that are at the forefront of developing and implementing green technology solutions.

By investing in these technologies, startups not only enhance their energy efficiency and operational sustainability but also significantly reduce their tax liability. This ultimately contributes to the growth and competitiveness of these startups in the renewable energy landscape.


Tax incentives play a crucial role in fostering a favourable environment for green energy startups in the UK. Through schemes like EIS, SEIS, R&D tax credits, capital allowances on green technology, ECAs, SITR, and carbon pricing, the UK government is effectively promoting private investment in the green energy sector.

These incentives not only help startups to offset their operational and R&D costs but also attract investors by offering them significant tax reliefs. This combination of benefits facilitates the growth of the green energy sector, driving the country towards its net-zero emission target.

Ultimately, these tax incentives not only stimulate the growth of green energy startups but also contribute towards creating a sustainable low-carbon future. By supporting these startups, the UK is paving the way for advancements in renewable energy technologies and innovative solutions to combat climate change.

As we move further into the era of green business, it is anticipated that the UK government will continue to introduce new tax incentives and initiatives to further stimulate the sector and help the nation transition to a more sustainable future.
