The UK impact investing market report 2024

Social Finance was commissioned by the Impact Investing Institute (III) to co-produce their second report estimating the size and potential of the UK impact investing market.

Published:16 September 2024

A collaborative approach

Our research for the report drew on primary data collected through a market participant survey conducted in partnership with the Global Impact Investing Network (GIIN)

The survey gathered insights from 72 UK-based impact investors, combining quantitative responses with qualitative perspectives from 35 semi-structured interviews involving a diverse group of market participants and experts in the UK and globally.

This was the first time that the Impact Investing Institute had collaborated with GIIN on data collection and this was an important step forward in bringing together different impact investing market sizing efforts and improving the comparability of data across market

This report highlights the huge opportunities that exist and the potential for impact investment to radically improve our daily lives. More than that, it shows how these investments benefit everyone with skin in the game

Key findings

76.8 billion
Size of impact investing market in assets under management (AUM) as at end of 2023
19.3 billion
Increase in market size since inaugural report published 2022
  • The UK impact investing market has grown to £76.8 billion in assets under management (AUM) as of end-2023. This marks a £19.3 billion increase from the Institute’s inaugural report and represents a 10.1% compound annual growth rate from the beginning of 2021 until the end of 2023.
  • Impact investing growth has significantly outpaced that of the broader UK asset management sector, which had an annual growth rate between ‑2% and 0% over the same period. We estimate that impact investing now accounts for just under 1% of the whole UK investing market.
  • UK-based impact investors are supporting impactful companies, projects and assets in the UK (34%) and across the globe (66%). Two-thirds of survey respondents plan to increase or sustain their allocation of capital towards companies, projects, and assets in the UK in the next five years.
There is immense potential for partnerships that can mobilise resources at scale to address pressing social, environmental, and economic challenges. Through blended finance structures and a focus on measurable outcomes, these collaborations can unlock capital that transforms lives across the UK and beyond.
