Sustainable Infrastructure
Building infrastructure for a more sustainable future
We create, invest in, and manage specialist businesses delivering the environmental and social infrastructure needed for a more resilient economy.
Our experience spans nature restoration, industrial decarbonisation, digital connectivity, specialist care, sustainable production and essential waste treatment.
We focus on businesses addressing clear environmental or societal needs, supported by structural demand and significant barriers to entry.
How we create value
We combine infrastructure investment discipline with active ownership, working alongside management teams to strengthen governance, improve operational and financial performance, scale proven business models and create long-term value. Through active management, we seek to:
- Build resilient and scalable operating platforms
- Strengthen governance and operational capability
- Convert underlying demand into sustainable revenues
- Improve financial performance and long-term strategic value
- Deliver measurable environmental and social outcomes
Our portfolio focuses on six key areas
Decarbonisation
Solutions supporting the decarbonisation of hard-to-abate industries.
Digital infrastructure and connectivity
Fibre networks, managed connectivity and digital services for businesses and communities.
Health and education
Specialist healthcare, dementia care, children’s nurseries and education.
Regeneration
Biodiversity net gain, habitat banks and investible nature-based solutions.
Resource efficiency
Resource-efficient food and plant production, controlled-environment horticulture, alternative proteins and water-efficient systems.
Waste solutions
Infrastructure that treats waste safely, recovers value and supports a more circular economy.
Building nature into an institutional asset class
Investing in nature requires more than capital. It requires specialist origination, operating capability and the investment discipline to turn emerging nature markets into scalable, institutional-quality opportunities.
We did not just invest in a nature market, we helped create one.
Gresham House identified the opportunity to apply infrastructure investment discipline to large-scale nature restoration and built the #1 specialist platform in the UK needed to deliver it.
Our first-of-its-kind biodiversity strategy transforms policy-driven demand into institutional-quality investments, combining cash generation and attractive return potential with measurable nature recovery secured for the long term.
Sustainable Infrastructure solutions
Gresham House Biodiversity
From statutory demand to institutional returns
Anchored in England’s statutory Biodiversity Net Gain market, the strategy uses carefully designed investment structures to combine private credit and infrastructure characteristics, including contractual income and structured downside mitigation, with participation in the growth of Environment Bank and emerging nature markets.
Portfolio in focus, Environment Bank: Building the UK’s biodiversity infrastructure
Environment Bank is the market-leading nature restoration business and the specialist operating platform at the heart of the strategy. Bringing together land origination, ecology, planning, sales and long-term habitat management, Environment Bank has created the #1 national platform capable of delivering nature restoration at scale.

Key risks
The value of your investment and the income from it is not guaranteed and may fall as well as rise. As your capital is at risk you may get back less than you originally invested. Past performance is not a reliable indicator of future performance.
