Renewable energy company Thrive Renewables has launched a £5 million bond, giving investors the chance to support new clean energy projects with an interest rate of 5.5 per cent per year.
The offer, available through Triodos Bank UK’s crowdfunding platform, allows individuals to invest directly in renewable energy infrastructure – including two new onshore wind farms planned for Scotland and Wales.
Money raised through the bond will also help provide funding for community-owned energy projects across the UK.
Funding new wind power
One of the projects supported by the raise will be Thrive’s largest development to date – a 57MW wind farm in the Scottish Borders made up of 14 turbines.
Once operational, the site could generate up to 149,400 MWh of clean electricity every year, enough to power the equivalent of around 45,000 average UK homes and cut an estimated 65,300 tonnes of carbon emissions annually.
The bond will also help fund Abergorki wind farm in Rhondda Cynon Taf, South Wales, a three-turbine project expected to begin operating in 2027. It could generate up to 40,000 MWh of electricity each year, enough to power more than 12,400 Welsh homes.
Together, the two projects are expected to provide enough renewable electricity to sustainably power the equivalent of more than 57,000 households annually.
‘People-powered investment’
Matthew Clayton, CEO of Thrive Renewables, said the bond continues the organisation’s long tradition of enabling individuals to invest directly in the clean energy transition.
“For thirty years we’ve been proving that people-powered investment can accelerate the UK’s transition to clean energy. With this new bond, investors will be directly enabling the construction of two major wind farms, alongside strengthening the community energy movement we’ve championed for decades.
“We know many people are looking for ways to take meaningful climate action, and this offer gives them the chance to do exactly that – backing real projects, delivering real impact.”
Whitni Thomas, head of corporate finance at Triodos Bank UK, said the offer will appeal to investors who want their money to support tangible climate solutions.
“Values-led investors want opportunities that combine strong climate impact with a transparent, mission-driven approach. By helping finance two new onshore wind farms and further community energy initiatives, investors will be contributing to the kind of systemic change the UK urgently needs.”
Why renewable energy investment matters
Renewable energy is playing an increasingly central role in the UK’s electricity system as the country moves away from fossil fuels.
Community-backed projects like those supported by Thrive allow individuals to invest directly in the infrastructure needed to power homes and businesses with clean energy in their local area.
Founded almost three decades ago, Thrive Renewables has raised £63 million through crowdfunding to support 45 wind, solar and hydro projects across the UK.
How the bond works
The new bond has a five-year term and offers 5.5 per cent gross interest per year, paid annually in arrears.
Key details include:
- Target raise: £5 million (part of a wider £10 million fundraising)
- Term: five years
- Interest: 5.5 per cent gross per year
- Minimum investment: £25
- Closing date: 16 April 2026 (unless fully subscribed earlier)
The bond can also be held inside a Triodos Innovative Finance ISA (IFISA), meaning interest may be received tax-free, subject to eligibility rules and individual tax circumstances. ISA eligibility does not guarantee returns or protect consumers from losing their money.
With the offer running until mid-April, it spans both the current tax year and the start of the new ISA season, meaning investors could choose to use either their remaining ISA allowance for this year or part of their new allowance from April.
Understanding the risks
As with all investments of this type, capital is at risk and returns are not guaranteed.
Interest payments and repayment of capital depend on the performance of the projects and may not be paid if things go wrong. Investments are not covered by the Financial Services Compensation Scheme (FSCS).
Investors should read the full offer document carefully and consider seeking independent financial advice if they are unsure whether the investment is suitable.
