A secured business loan uses a business or personal asset – property, equipment, or a director’s personal guarantee backed by assets – as collateral in exchange for lower interest rates and access to larger sums. In 2026, UK secured business loan rates start from around 6% APR for strong applicants with property security, compared to 15–50%+ for equivalent unsecured borrowing.
- Secured loan rates start from 3.5% - significantly lower than unsecured alternatives which typically range from 8% to 25% annually
- Asset-backed loans unlock up to £10 million - perfect for established businesses needing substantial capital for expansion or equipment purchases
- Property-secured options beat bank rates by 2-4% - though risking asset loss makes thorough comparison with specialist lenders like Atom Bank essential
- Application approval takes 2-6 weeks - slower than unsecured loans but faster processing available through challenger banks versus traditional providers
- Equipment finance covers 80-100% of asset value - ideal alternative to property security while building business credit history simultaneously
What Is a Secured Business Loan?
A secured business loan is a term loan where the borrower pledges an asset – commercial or residential property, equipment, or other business assets – as security against the loan. If the business defaults, the lender can seize the asset to recover its money. In return for this security, lenders offer lower interest rates, larger loan amounts, and longer repayment terms than equivalent unsecured products.
The most common form of business security in the UK is a charge over commercial property, either owned by the business or by a company director personally. For smaller loans, lenders often accept a personal guarantee instead of a formal charge – technically not a “secured” loan in legal terms, but functionally similar if the director has personal assets behind the guarantee.
Secured lending gives lenders a clear recovery route if you default, which is why rates are substantially lower than unsecured equivalents. The key structural difference from unsecured loans: if you default, the lender’s first recourse is the pledged asset, not just legal action against you personally.
Secured vs Unsecured Business Loans: Key Differences
Use a secured loan when you need more than £100K, want the lowest possible interest rate, or need a term longer than 5 years. Use an unsecured loan when you need speed, don’t have assets to pledge, or need less than £100K and can absorb a higher rate. The rate differential between secured and unsecured is typically 5–15 percentage points – enough to make a meaningful difference on large or long-term borrowing.
| Factor | Secured Loan | Unsecured Loan |
|---|---|---|
| Typical APR | 6–15% | 15–60%+ |
| Loan amount | £25K–£25M+ | £1K–£500K (most lenders) |
| Repayment term | 1–25 years | 3 months–7 years |
| Application time | 2–8 weeks (valuation required) | 24 hours–2 weeks |
| Asset at risk? | Yes – pledged asset | No (personal guarantee only) |
| Credit requirement | Moderate–strong | Moderate (flexible with alt lenders) |
Types of Secured Business Loan
The main types of secured business loan in the UK are: commercial mortgages (buy or refinance business premises), asset finance (secured against the equipment or vehicle being purchased), bridging loans (short-term property-secured finance, typically 1–18 months), and secured term loans (general-purpose, secured against existing property or assets). Each has a different use case, term profile, and lender market.
Commercial mortgages are secured against commercial property and used to purchase, develop, or refinance business premises. Terms run 5–25 years at rates typically 1–3% above the Bank of England base rate. Minimum loan is usually £50K–£100K, and a 25–40% deposit is standard for new purchases.
Asset finance (hire purchase, finance lease) is secured against the asset being acquired – vehicles, plant, machinery, technology. The asset itself is the security, which reduces rates significantly compared to unsecured equipment purchases. Ownership transfers to the business at end of term (hire purchase) or the asset is returned (finance lease).
Bridging loans are short-term (1–24 months), high-value, property-secured finance used to bridge a gap – typically between buying a new property and selling an old one, or completing a development while awaiting permanent finance. Rates are higher than commercial mortgages (0.5–1.5% per month) but the speed of completion (days rather than weeks) justifies the cost in time-sensitive situations.
Secured Business Loan Rates in 2026
Secured business loan rates in the UK start from approximately 6% APR for the strongest applicants with substantial property security, and range up to 18–20% APR for higher-risk profiles or non-standard properties. With the Bank of England base rate at 4.75% (March 2026), variable-rate secured loans are typically priced at base rate plus 1.5–5%. Commercial mortgage rates cluster between 6–10% for standard investment properties.
The rate you receive depends primarily on: loan-to-value ratio (lower LTV = lower rate), property type and condition, your business’s financial strength, loan amount and term, and whether you take a fixed or variable rate. Most banks price secured loans individually – the rates shown on websites are indicative rather than guaranteed.
How to Apply for a Secured Business Loan
Applying for a secured business loan involves additional steps compared to unsecured lending: a professional valuation of the security asset is required, which takes 2–4 weeks and costs £500–£1,500. You’ll also need a solicitor to handle the legal charge registration at Companies House. Budget 4–8 weeks for the full process from application to funds. Brokers who specialise in commercial lending can significantly accelerate this by preparing your application correctly before submission.
- Identify your security – which asset you’re pledging, its estimated value, and whether it has any existing charges (mortgages or loans already secured against it).
- Prepare your financials – 2 years of filed accounts, 6 months of bank statements, cash flow forecasts. Secured lenders conduct more thorough due diligence than unsecured lenders.
- Get a professional valuation – most lenders require a RICS-qualified valuer to assess property used as security. This is typically arranged by the lender and costs £500–£1,500, payable by the borrower.
- Appoint a solicitor – the legal charge must be registered at Companies House (for company assets) or HM Land Registry (for property). Solicitor fees are typically £1,000–£3,000 depending on complexity.
- Review the facility letter carefully – check the charge type (fixed vs floating), repayment schedule, early repayment penalty, and what triggers a default clause.
Alternatives to Secured Business Loans
If you don’t have assets to secure against, or need funds faster than a secured loan allows, the main alternatives are: unsecured business loans (higher rate, no asset risk, faster), invoice finance (if the cash flow gap is driven by unpaid invoices), or a revolving credit facility (for recurring short-term needs). For property-related funding, development finance and commercial bridging are secured alternatives that operate faster than standard commercial mortgages.
