    What it is

    What is ESG and impact investing?

    ESG investing screens for environmental, social and governance quality; impact investing goes further and targets a measurable outcome — a wind farm built, homes delivered, emissions avoided.

    In UK private markets the two blur: most platforms fund specific projects or ventures where the impact is the product, and the structure — bond, share or fund — sets the risk more than the label does.

    How it works

      Structure

      Capital is raised as a bond, debenture, community share or EIS fund.

    Risks

    What can go wrong

    Capital is at risk. Most ESG and impact investing products are high-risk investments under FCA rules and may require an appropriateness assessment.

    Capital at risk

    Community bonds are unsecured and outside the FSCS.

    Illiquidity

    Most bonds have no secondary market until maturity.

    Greenwashing

    Impact claims vary in rigour; check reporting and third-party verification.

    Regulatory status

    Several platforms are not FCA-authorised — check the register.

    Project risk

    Single-asset bonds depend on one wind farm, one development.

    Venture risk

    Climate-tech equity carries full startup failure risk.

    FAQ

    ESG & Impact questions

    What is the difference between ESG and impact?
    ESG screens investments on environmental, social and governance quality; impact investing targets a measurable positive outcome as a goal in itself.
    Are community bonds safe?
    No — they are unsecured, illiquid and outside the FSCS. Default rates have been low but capital is fully at risk.
    What returns do impact bonds pay?
    Typically 4–7% fixed over 3–10 years, paid annually or semi-annually.
    Can I get tax relief?
    Yes for climate-tech EIS/SEIS funds (30–50% income tax relief); some bonds qualify for an Innovative Finance ISA.
    How do I avoid greenwashing?
    Look for third-party verification, named projects, and published impact reports. The FCA Sustainability Disclosure Requirements now govern fund labels.
    Are these platforms FCA regulated?
    Some are, some are not. Ethex and Green Angel Ventures operate outside FCA authorisation; Abundance and Triodos are directly authorised.
