Santander offers business loans from £2,000 to £25,000 at a representative APR of 7.9%, with a headline feature no other major bank matches: 12 months interest-free on its Small Business Loan. Combined with no arrangement fees and government-backed Growth Guarantee Scheme support, Santander is a strong contender for cost-conscious businesses. Here is our independent review.
- Loan amounts from £2,000 to £25,000 - competitive range for SMEs with representative APR of 7.9% for established businesses
- Best for established businesses with 2+ years trading - Santander requires strong credit history & existing business relationships
- No early repayment penalties across all loan products - unique advantage that major competitors like Barclays & HSBC don’t match
- Limited loan ceiling at £25,000 maximum - significantly lower than competitors offering £500,000+ for larger business expansion needs
- 7.9% APR beats high street rivals by 2-3% - more competitive than typical 10-12% rates from Lloyds & NatWest business lending
What Is Santander Business Loans?
Santander offers a Small Business Loan (up to £25,000 with 12 months interest-free), a Larger Business Loan (from £25,001), and participates in the UK Government’s Growth Guarantee Scheme for medium-sized lending.
Santander is one of the UK’s five largest banks and refreshed its business lending products in October 2025. The standout feature is the 12-month interest-free period on its Small Business Loan — meaning you pay nothing in interest for the first year, regardless of the amount borrowed.
At 7.9% representative APR, Santander sits between HSBC’s 7.1% (the lowest major bank rate) and Barclays’ 11.2%. When you factor in the interest-free year, Santander’s total cost of borrowing can actually undercut HSBC for loans held beyond the first year.
Santander Business Loans: Pros and Cons
Santander’s 12-month interest-free period is unique among UK banks and makes it the cheapest option for short-to-medium term borrowing, but you must hold a Santander business current account.
What Business Loan Products Does Santander Offer?
Santander has three products: a fixed-rate Small Business Loan with 12 months interest-free, a Larger Business Loan with dedicated relationship support, and government-backed Growth Guarantee Scheme lending.
| Product | Amount | Term | Rate | Key Feature |
|---|---|---|---|---|
| Small Business Loan | £2,000 – £25,000 | 1–5 years | 7.9% APR (fixed) | 12 months interest-free |
| Larger Business Loan | From £25,001 | Up to 25 years | Bespoke | Dedicated relationship team |
| Growth Guarantee Scheme | From £25,001 | 12 months – 6 years | Bespoke | Government-backed (since July 2024) |
The 12 months interest-free feature on the Small Business Loan is Santander’s unique selling point. No other major UK bank offers a similar interest-free introductory period. For a £20,000 loan over 3 years, this could save you approximately £1,500 in interest compared to paying the full 7.9% from day one.
The Growth Guarantee Scheme is a UK Government initiative that provides lenders with a partial guarantee, enabling them to offer loans to businesses that might not otherwise qualify. Santander has participated since the scheme launched in July 2024. Amounts start at £25,001 with terms of 12 months to 6 years.
Santander Business Loan Rates and Fees
Santander charges 7.9% representative APR with no arrangement fees. The first 12 months are interest-free, making the effective cost of borrowing lower than the headline rate suggests.
When comparing total cost of borrowing, Santander’s interest-free year can make it cheaper than HSBC despite HSBC’s lower headline rate of 7.1%. For example, on a £15,000 loan over 3 years, Santander saves approximately £1,185 in interest during the free period while HSBC charges from month one.

Santander Business Loan Eligibility
You must hold a Santander business current account and cannot be a director of a business that failed within the last 6 years. Sole traders, partnerships, LLPs, and limited companies are eligible.
Santander’s key eligibility requirements:
- Account requirement: Santander business current account (mandatory)
- Business types: sole traders, partnerships, LLPs, private limited companies, trusts
- Director check: cannot have been a director of a business that failed within the last 6 years
- Credit check: standard assessment applies
The mandatory Santander account requirement is the biggest barrier. If you do not already bank with Santander, you will need to open a business current account before applying for a loan, adding time to the process. If you need a loan without switching banks, HSBC and Barclays do not require existing accounts. For businesses with adverse credit, see bad credit business loans.
Santander vs Alternative Business Lenders
Santander’s 12-month interest-free period and 7.9% APR make it the most cost-effective Big Five bank loan for short-to-medium term borrowing, provided you hold a Santander account.
| Lender | Representative APR | Interest-Free Period | Max Unsecured | Account Required? |
|---|---|---|---|---|
| Santander | 7.9% | 12 months | £25,000 | Yes |
| HSBC | 7.1% | None | £25,000 | No |
| Barclays | 11.2% | None | £25,000 | No |
| NatWest | 12.24% | None | £100,000 | Recommended |
On total cost of borrowing, Santander can beat HSBC for loans held beyond 12 months thanks to the interest-free year. For very short-term borrowing, the interest-free period makes Santander the clear winner. The catch is the mandatory account requirement, which HSBC and Barclays do not impose.

Our Verdict on Santander Business Loans
The cheapest total cost of borrowing from any major bank thanks to the 12-month interest-free period, but requires a Santander business account.
Santander’s 12-month interest-free period makes it the most cost-effective high-street bank loan, but you must already hold or be willing to open a Santander business account.
If you bank with Santander — or are willing to open an account — the interest-free year makes this the cheapest borrowing option from any major UK bank for loans held beyond 12 months. The 7.9% representative APR is competitive in its own right, and the absence of arrangement fees keeps the total cost low.
The forced account requirement and director disqualification rules will not suit everyone. If you want a loan without switching banks, HSBC or Barclays are simpler. For a full comparison, see our best business loans guide.
