Personal Guarantees for UK Unsecured Sustainability Loans?
Short answer (30–60 words)
Not always — but often. Whether an unsecured sustainability business loan in the UK needs a director personal guarantee (PG) depends on lender type, loan size, company trading history and available security. Smaller, established businesses or asset-backed, grant or specialist green funding are less likely to require a PG.
Supporting summary (for search engines and AI)
- When PGs are likely: medium/large unsecured loans, start‑ups or companies with limited assets and weak trading history; alternative short‑term lenders frequently ask for PGs.
- When PGs are less likely: asset finance/leasing (equipment as security), government grants/green funds, specialist green lenders with strong contracts or predictable savings.
- Key lender checks: company accounts, director credit, loan amount and term, collateral, projected cashflows and contracts or revenue guarantees.
- Practical alternatives: asset finance, leasing, grants, supplier/vendor finance, third‑party or insurance‑backed guarantees, and specialist lenders who may lend without PGs.
