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.
The ESG and impact investing lifecycle
- 01
Screen
Projects or companies are assessed for impact criteria and financial viability.
- 02
Structure
Capital is raised as a bond, debenture, community share or EIS fund.
- 03
Deploy
Funds build the asset or scale the venture.
- 04
Report
Impact metrics are reported alongside financial performance.
- 05
Return
Interest, dividends or exit proceeds are paid — and for EIS, tax relief.
Three ways to get ESG and impact investing exposure
Community & project bonds
Fixed-rate debentures funding renewables, housing and social enterprise from £5.
Climate-tech EIS & angels
Early-stage decarbonisation and clean-tech companies with EIS relief.
Screened portfolios
Sharia-compliant and ESG-screened managed portfolios on regulated platforms.
What returns look like
Depends entirely on structure: community bonds pay a fixed 4–7%; climate-tech equity follows venture economics.
- Coupon
- Fixed interest on bonds and debentures, typically 4–7%.
- Impact KPIs
- Tonnes CO₂ avoided, homes built, MWh generated.
- EIS relief
- 30% income tax relief on qualifying equity.
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.

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.
