SyndicateRoom, one of the United Kingdom’s leading venture capital investment platforms, has announced that its Climate Tech SEIS Fund—managed in partnership with Carbon13—has exceeded its initial investment targets. The development comes at a time when investor appetite for sustainable, tax-efficient opportunities is reaching unprecedented levels.
According to recent industry data, investment in UK climate tech rose by 24% in 2024, hitting £4.5 billion. This growth reinforces the UK’s position as a global frontrunner in climate technology, with the sector accounting for 80% to 90% of all impact investment in the country.
The fund’s success also mirrors broader trends in the Seed Enterprise Investment Scheme (SEIS). More than 10,145 investors claimed SEIS tax relief in the 2023–2024 period, benefiting from incentives such as up to 50% income tax relief and tax-free capital gains. As year-end financial planning intensifies, these incentives are drawing heightened interest, especially with new caps set to affect Cash ISAs.
“With the cap coming in on Cash ISAs, investors may wish to explore opportunities that put their money to work for both their own benefit and that of our environment,” said Tom Britton, Co-founder of SyndicateRoom.
Through its partnership with Carbon13, SyndicateRoom is backing early-stage ventures that address urgent environmental challenges across renewable energy, sustainable agriculture, carbon capture, and circular economy innovation. Carbon13’s venture-building expertise ensures that high-potential founders receive the support needed to scale impactful solutions.
“2025 has demanded a renewed focus on how we continue to work on the world’s most urgent problems – ambitious founders want nothing less,” noted Dr. Nicky Dee, Founder and CEO of Carbon13.
SyndicateRoom’s co-investment model allows individual investors to invest alongside seasoned angel investors, providing strong due diligence and portfolio diversification. Since 2012, the platform has deployed over £77 million into more than 250 startups, leveraging an accessible online process that broadens participation in early-stage investing.
The rapid expansion of the UK’s climate tech ecosystem presents a compelling opportunity for investors seeking both environmental impact and financial returns. With tax advantages such as income tax relief, capital gains exemptions, and inheritance tax benefits, SEIS continues to be one of the most attractive pathways for high-net-worth individuals and forward-thinking financial advisors.
As the year draws to a close, advisors are increasingly integrating climate tech into diversified portfolios—aligning client values with long-term wealth strategies. The performance of SyndicateRoom’s Climate Tech SEIS Fund underscores a growing truth: sustainable innovation and strong financial returns can go hand in hand.
