    Our approach

How is the market size calculated?

The UK Social impact investment market is a subset of the broader UK impact investment market. For the purposes of our market sizing exercise, we define social impact investment as:

‘Investment into social purpose organisations such as charities, social enterprises and impact start-ups, or real assets such as social and affordable housing. The investment enables them to deliver products or services that create measurable, lasting social impact that improves people’s lives. Social impact investors are seeking positive social impact as well as a financial return and both investees and investor demonstrate social impact intent.’

To calculate an estimate of the market size, we use the following methodology to guide the research.

  1. Build and refresh the market list of impact investing organisations that meet our definition and criteria
  2. Define the key metrics and definitions for market sizing approach

The two main metrics captured in this annual exercise include:

  • Size £m - Outstanding amount/value, as at the end of the calendar year. We also include an estimate of the number (i.e. # count) of transactions between Fund Manager & Frontline/Asset that make up the size £m.
  • Deal flow £m – The amount (and #) of new commitments made during the calendar year.
  1. Collect and aggregate key metric data for the market list of impact investing organisations
  2. Collate and estimate the investor composition of the market
  3. Benchmark our findings and compare to our prior years and other organisations’ market sizing reports
