Social Impact Debt Fund IV

This fund lends to established socially impactful organisations in the UK, with a history of revenue generation, profitability, and assets to support the secured debt.

Investment Overview

this is the logo for the social impact debt fund IV for secured loans. It is green words.

Social Impact Debt Fund IV launched in September 2023 and is actively investing. The fund offers secured loans for asset-backed growth, for borrowers creating an impact in the below sectors:

  • Health and Social Care
  • Affordable Housing and Homelessness
  • Community and Social Infrastructure

The fund offers unitranche loans, which have a single set of terms, instead of a combination of senior bank debt and separate mezzanine debt funding. This means that borrowers are not required to coordinate with complex syndicate structures that delay execution timelines and complicate capital structures.

Eligible borrowers will be established socially impactful organisations in the UK, with a history of revenue generation, profitability and assets to support secured debt.

Social enterprises borrowing from the fund are expected to deploy the funding to improve their financial sustainability and scale-up existing impact.

Please note: Fund IV does not invest in Community Development Financial Institutions (CDFIs), lending businesses, property development businesses, house builders or manufacturers or organisations operating in business areas outside our three core focus sectors.
