If you’re searching for a UK Government small business loan under £25,000 in 2026, this is your map. There are essentially two routes: the British Business Bank Start Up Loan (Government‑backed, personal-name, up to £25k, includes mentoring) and a commercial small business loan from a specialist non-bank lender. Once you need £25,001+, the Growth Guarantee Scheme takes over.
Both are legitimate, regulated products. The right one depends on whether you’re trading already, how fast you need funds, and whether you value the mentoring side of the Government scheme.
The right product depends on stage and amount. Here’s how the three main UK SME funding routes compare in 2026.
| BBB Start Up Loan | Commercial small business loan | Growth Guarantee Scheme | |
|---|---|---|---|
| Government‑backed? | Yes — run by the British Business Bank | No — commercial product | Yes — 70% guarantee from BBB |
| Amount | £500 — £25,000 personal-name | £1,000 — £100,000+ | £25,001 — £2,000,000 |
| Term | 1 — 5 years | 3 months — 5 years | 1 — 6 years |
| Typical rate | 6% fixed APR | 8% — 30% APR | ~7.5% — 16% APR |
| Stage | Pre-trading or under 36 months trading | Trading 6+ months | Trading 12+ months typically (some lenders 6+) |
| Speed to drawdown | 4 — 8 weeks | 24 — 48 hours | 5 — 15 working days |
| Mentoring included | Yes — 12 months free | No | No |
| Personal liability | Personal-name — full personal liability | Often a director PG | Often a director PG — PPR (home) cannot be taken |
Yes. The British Business Bank Start Up Loan is the official UK Government small business loan for amounts up to £25,000 per person. It’s personal-name, fixed at 6% APR, repayable over 1–5 years, and comes with 12 months of free mentoring. It’s aimed at pre-trading entrepreneurs and businesses trading under 36 months. Applications go via approved delivery partners listed on gov.uk/apply-start-up-loan.
The Start Up Loan is personal-name, Government‑backed, fixed at 6% APR, and includes mentoring — but capped at £25k per person and slow to fund (4–8 weeks). A commercial small business loan from a specialist non-bank lender is faster (24–48 hours), can be larger, but priced commercially (8–30% APR) and has no mentoring.
National UK Government grants under £25,000 are rare and competitive. The closest equivalents are local-council UKSPF (UK Shared Prosperity Fund) micro-grants of £1k–£10k, devolved-administration grants in Scotland (Scottish Enterprise), Wales (Business Wales) and Northern Ireland (Invest NI), and (where eligible) Innovate UK feasibility grants.

Yes — via the British Business Bank Start Up Loan. Pre-trading and very early-stage businesses don’t typically qualify for commercial small business loans (most require 6+ months of trading history) or for the Growth Guarantee Scheme (most lenders require 12+ months trading).
Yes — via the Growth Guarantee Scheme, which is the UK Government’s flagship SME funding programme for amounts of £25,001 to £2,000,000. GGS isn’t a direct Government loan; it’s a 70% guarantee the British Business Bank provides to accredited commercial lenders, letting them lend larger amounts to viable businesses they’d otherwise decline.
Yes. The Start Up Loan is capped at £25,000 per person, but multiple co-founders can each apply. The Start Up Loans Company allows up to £100,000 per business in aggregate across all co-founder applications, subject to each individual qualifying.
For amounts under £25k and businesses that qualify, the British Business Bank Start Up Loan at 6% fixed APR is one of the cheapest UK small business loan products. For amounts of £25k+, a Growth Guarantee Scheme term loan typically prices 7.5%–13% APR for a strong UK SME profile — cheaper than commercial-only alternatives at the same amount.
