Smaller businesses across a large part of the South East can now apply for commercially priced debt from £25,000 to £2 million through a new British Business Bank regional investment fund. It is growth finance, not grant funding, and London is outside the fund area.
Section 01
What has launched?
The South East Investment Fund is part of the British Business Bank’s Nations and Regions Investment Funds programme. It launched on 9 September 2026 with £210 million to invest through loans and equity in smaller businesses that can contribute to regional growth.
The debt range runs from £25,000 to £2 million. The same fund can make equity investments up to £5 million, but founders should not treat debt and equity as interchangeable. A loan requires repayment and may involve security or guarantees; equity changes the ownership of the company and the investor’s participation in future value.
Section 02
Which businesses are in the area?
The published coverage includes Buckinghamshire, Oxfordshire, Berkshire, Hampshire and the Isle of Wight, Sussex, Surrey and Kent. London is not included. Businesses close to a boundary should confirm eligibility with the fund manager before spending time on a full application.
A company can normally qualify by being headquartered in the region or having a significant operating presence there. A registered-office address on its own may not prove that presence. Expect questions about employees, facilities, customers, economic impact and where the financed activity will take place.
Section 03
What can the loan fund?
Regional investment loans are intended for viable new or growing businesses. Common cases include additional staff, production capacity, equipment, premises, market entry, product development and working capital attached to a credible expansion plan.
The strongest request connects the amount borrowed to a defined use and then to cash generation. For example, a manufacturer might show the cost and delivery date of a new line, its additional output, contracted demand, gross margin and the headroom left after repayments.
- State the funding amount and use of proceeds line by line.
- Provide filed accounts, current management figures and realistic forecasts.
- Explain the management team’s relevant experience and delivery plan.
- Show the wider funding package, including owner investment and existing debt.
- Identify downside scenarios and the actions available if revenue is delayed.
Section 04
Commercial loan, not a grant
The regional label does not make the money free or government-guaranteed for the borrower. Interest, fees, term, repayment profile, security and possible personal guarantees are set through the fund manager’s assessment. The company remains liable for the agreed debt.
Compare the regional-fund offer with bank, specialist-lender and asset-backed alternatives. A slightly higher headline rate can still be the better offer if it comes with a longer term, patient capital, lower fees or a repayment structure that fits the project. Equally, the fund should not displace a simpler, cheaper facility already available.
Section 05
What happens next?
Applicants should start at the official fund page, check location and business eligibility, and contact the named debt fund manager. The launch programme includes regional roadshows in Reading, Southampton and Margate on 6–8 October 2026.
Businesses in the East of England should not use the South East route unless their operations fall within its published area. A separate East of England Investment Fund was still marked as coming soon at publication and was expected later in September 2026.
