What Gresham House does

Gresham House is a specialist alternative asset manager focused on sustainable investments, headquartered in London with offices across the UK, Ireland, Switzerland, Liechtenstein, Germany and Singapore. The firm operates across three principal verticals: Real Assets (forestry, energy transition including battery energy storage systems, sustainable infrastructure, and UK housing); Strategic Equity (public equity small-cap strategies, private equity and Venture Capital Trusts); and Social Impact (social housing and public sector debt via TradeRisks). The firm manages approximately £10.7bn in assets as of 31 December 2025 and holds the No. 1 position in UK commercial forestry (IPE Real Assets, January 2026) and a Top 10 ranking among European energy transition asset managers (Indefi, June 2025). Its product set spans listed investment trusts (GRID, SEC, ReSI), VCTs (Baronsmead, Gresham House Income & Growth, Renewable Energy VCTs), open-ended funds, and private vehicles including British Sustainable Infrastructure Fund II and the SUSI Asia Energy Transition Fund.

The firm's revenue model is built on management fees (subscription/recurring) levied on fee-earning AUM, supplemented by performance fees (carried interest) and dividend/interest income from balance sheet investments. Disclosed FY2025 net core income of £90.3mn (+30% CAGR 2018-2025) generated £40.0mn EBITDA (+45% CAGR 2018-2025), implying a 44.4% EBITDA margin on net core income and 25.9% ROCE. Fund LP commitments have a 13-year weighted-average life, providing long-duration revenue visibility. Distribution operates through three primary channels: direct institutional sales (regional heads covering UK, Benelux, Nordic), wholesale distribution via IFAs and wealth platforms, and public markets via LSE-listed investment trusts and VCT subscription offers.

Gresham House was originally incorporated in 1857 and transformed into its modern form in December 2014 when Tony Dalwood led a management buy-in, pivoting from an investment trust to a specialist asset manager. The firm has executed an aggressive acquisition strategy, integrating Aitchesse (forestry, 2015), Hazel Capital (energy, 2017), FIM Services (2018), Livingbridge VC (2018), TradeRisks (2020), Appian Asset Management (2020), Burlington Real Estate (2022), Mobeus VCTs (2021), and most recently SUSI Partners (2026) and Molpus Woodlands Group (2026). In December 2023 the firm was acquired by Searchlight Capital Partners and delisted from the LSE, with management continuing under private ownership.
