Rachel Reeves used her Mansion House speech this week to announce a significant expansion of small business lending, and the detail matters more than the headline. The Growth Guarantee Scheme — which gives lenders a 70% government guarantee on commercial loans to SMEs — is scaling up to unlock an extra £2 billion of funding by 2028/29. If your business has ever been turned down for finance because a bank saw it as too risky to lend to unsecured, this is squarely aimed at you.
The scheme isn’t new, but the terms just got considerably more useful. Loan lengths for amounts up to £1.1 million are extending from six years to ten, giving businesses more breathing room on repayments. The maximum loan size under the wider scheme structure is rising too. The British Business Bank estimates the changes will support 12,000 businesses a year by 2028/29 — up from 8,000 today, a 150% increase in the number of firms getting access.
What’s actually changed, in practice
Longer terms on existing loan sizes. A ten-year term instead of six on loans up to £1.1 million means smaller monthly repayments for the same amount borrowed — useful if you’re financing equipment, premises, or a hiring push and want the cash flow to match a longer growth curve rather than a short one.
More money for export-focused lending. A new portfolio grant scheme, launching in spring 2027, is designed specifically to help exporting businesses access lending to expand into international markets — a gap that’s been repeatedly flagged as underserved.
£500 million through ENABLE Guarantee. This is aimed at innovative businesses whose main asset is intellectual property rather than physical collateral — the kind of business that’s historically struggled hardest to get a bank to say yes.
The catch: most eligible businesses won’t apply
Schemes like this consistently under-deliver relative to their headline numbers, not because the money isn’t there but because eligible businesses don’t know the scheme exists, assume they won’t qualify, or find the application process opaque. The 70% government guarantee exists specifically to make lenders more comfortable saying yes to businesses they’d otherwise decline — but you still have to ask.
If you’re weighing whether finance makes sense right now, it’s worth getting the legal and structural side sorted before you approach a lender. Smallprint’s template library covers the loan agreements and business documentation lenders will want to see, so you’re not starting that conversation from scratch. And if the funding is earmarked for a specific build — new systems, a custom app, an AI-driven process change — BuildApps can help scope what that investment actually needs to deliver before you commit to a repayment schedule around it.
Where to actually start
The Growth Guarantee Scheme is delivered through accredited commercial lenders, not directly by government, so the first practical step is asking your existing bank whether they participate — most of the major high street and challenger banks do. If they’ve declined you before on affordability or collateral grounds, it’s worth going back specifically now: the 70% guarantee changes the risk calculation on their side, not just the terms on yours. Businesses that were a “no” under the old scheme structure may find themselves a “yes” under the expanded one, particularly for longer-term borrowing against equipment, premises or growth capital.
The takeaway
An extra £2 billion in guaranteed lending capacity is only useful to the businesses that go and get it. If you’ve been putting off a finance conversation because you assumed the terms wouldn’t work, the terms just changed — check with your bank or a scheme-accredited lender whether the new Growth Guarantee terms apply to what you’re planning, before assuming the answer is still no.
