Small Business Bank Loans in the UK (2026): Types, Rates, Government Schemes and How to Get Approved

If you run a UK sole trader business, partnership or small limited company and you're thinking about borrowing from a bank, this guide is for you. It covers the main types of small business loan, what banks are actually charging in 2026 (with the date we checked), how the government-backed Growth Guarantee Scheme works after the July 2026 changes, what a personal guarantee commits you to, how lenders decide, and what to do if you're turned down. Worked repayments in pounds show what different loans really cost.

Quick answer

UK banks lend small businesses £1,000 to £25,000 unsecured over one to ten years, with larger loans usually needing security or a director's personal guarantee. On 9 October 2026, big-bank published representative APRs ran from about 8.5% to 14.9%, with Bank Rate at 3.75%. If you can't offer enough security, the Growth Guarantee Scheme gives lenders a 70% government guarantee on facilities up to £2 million.

• Representative APR is what at least 51% of accepted applicants get — yours may differ

• Smaller loans usually carry higher APRs than larger ones

• Under the Growth Guarantee Scheme you stay 100% liable, and your main home can't be security

• Refused by a big bank? The Bank Referral Scheme can pass your details to alternative lenders

• Start-ups with little trading history should also compare a government Start Up Loan

What counts as a small business bank loan

"Business loan" covers several different products, and choosing the wrong one is the most common and most expensive mistake. The right product depends on what you're paying for and how quickly the money comes back.

A term loan is a lump sum repaid in fixed monthly instalments over an agreed term. Banks usually offer unsecured term loans up to £25,000 and secured or larger loans above that. Use it for one-off investments that pay back over years: a fit-out, a vehicle, a new machine, or buying another business.

An overdraft or revolving credit facility covers short gaps in cash flow. You pay interest only on what you use, but banks can review or withdraw an overdraft, so it shouldn't fund long-term assets.

Asset finance (hire purchase or leasing) is secured on the equipment it buys, so it's often easier to get than an unsecured loan and doesn't tie up other assets. Invoice finance advances money against unpaid customer invoices, which suits businesses that sell to other businesses on 30 to 90-day terms. A commercial mortgage buys or refinances business premises over much longer terms.

Which type of business finance fits the job?

Product	Typical use	Security	Main catch
Unsecured term loan	Equipment, fit-out, growth projects	None, but a guarantee may be asked for	Higher APR on small amounts
Secured term loan	Larger investments, acquisitions	Business assets or property	Arrangement fees and valuations
Overdraft	Short cash-flow gaps	Often none for small limits	Repayable on demand; reviewed yearly
Asset finance	Vehicles, machinery, IT	The asset itself	You may not own it until the end
Invoice finance	Waiting for customers to pay	Your sales ledger	Fees on every invoice; customer may be told
Commercial mortgage	Buying premises	The property	Large deposit; long commitment

As a rule, match the term of the finance to the life of what it pays for. Funding a van you'll keep for five years with an overdraft creates constant pressure; funding stock that sells in eight weeks with a seven-year loan means paying interest long after the stock has gone.

Business loan interest rates and APR in 2026

Business lending rates follow the Bank of England's Bank Rate, which stood at 3.75% when we checked on 9 October 2026. Fixed-rate small loans are priced off the lender's funding costs plus a margin for risk, and larger variable-rate loans are usually quoted as a margin over Bank Rate, so your repayments rise and fall with it.

The headline figure you'll see is the representative APR. NatWest explains it as the rate it expects at least 51% of customers who are accepted and take out a loan to get. The other 49% may be offered more. APR includes interest and compulsory fees, which makes it the best single number for comparing quotes, but only if you compare the same amount over the same term.

Here's what three high street lenders were publishing for unsecured small business loans on 9 October 2026:

Banks change these figures without notice, and some of them say so on the page. Treat the table as a snapshot, not a quote. Two patterns are reliable, though. Small loans cost more in percentage terms, because the lender's fixed costs are spread over less money. And your own credit profile — trading history, accounts, personal credit file — moves the rate more than which bank you pick.

Fees matter too. Barclays and NatWest said they charge no arrangement or early repayment fees on their small unsecured loans. HSBC charges no arrangement fee but adds an administration fee if security is needed, and deducts one month and 28 days of interest from the rebate if you settle early. Larger and secured loans commonly carry arrangement fees, legal fees and valuation costs, which belong in your comparison.

What a business loan really costs: worked repayments

The table below shows standard amortising repayments at a range of annual rates. They're our own calculations to show the effect of rate and term, not any lender's offer. Your agreement will show the exact figures, which can differ slightly depending on how the lender calculates interest.

Why rate matters more than you'd think. The same £20,000 over five years costs £4,619.84 in interest at 8.5% and £8,484.97 at 14.9%, a difference of almost £3,900. If a slightly larger loan moves you into a cheaper APR band, that can be worth checking, but only if you genuinely need the money.

Why term matters. A longer term cuts the monthly payment and raises the total cost. On £150,000 at 9%, a ten-year term costs £1,900.14 a month and about £78,000 in interest; a seven-year term would cost £2,413.36 a month and about £52,700. Longer terms only make sense when cash flow genuinely needs the room.

Worked example: a joinery workshop. Priya's limited company makes fitted furniture and wants a £40,000 CNC router to take on more trade work. Her bank offers either an unsecured loan, with a director's guarantee, or asset finance secured on the machine. She asks for both quotes over five years and compares the total payable, the fees and the guarantee. The asset finance is secured on the router, so the bank doesn't ask for a personal guarantee, and the company can claim capital allowances on the machine either way. She also checks that the extra orders cover the repayment in her quietest month before she signs.

Personal guarantees: what you're really signing

A limited company is a separate legal person, so in principle its debts aren't yours. A personal guarantee changes that. If the company can't repay, the lender can come to you personally for the amount guaranteed. Lenders ask for them because they want directors to have "skin in the game", and because a young company may have few assets to secure.

Whether you're asked depends on the lender and the loan. NatWest says a personal, director or member's guarantee may be required on its small business loan. Under the Growth Guarantee Scheme, lenders can still take personal guarantees at their discretion, in line with their normal practice, but they can't take your principal private residence (main home) as security under the scheme.

Before you sign, understand three things. First, whether the guarantee is capped at a fixed sum or covers everything the company owes the lender, now and in future. Second, whether it's joint and several with other directors, which means the lender can pursue any one of you for the whole amount. Third, how it ends: a guarantee normally stays in force until the lender releases it in writing, even after the loan is repaid or you've left the company, unless the document says otherwise.

Independent oversight has ended. The Lending Standards Board, which ran a voluntary code covering personal guarantees for small business borrowers, closed in 2025 after the largest banks withdrew. Each lender now applies its own policies, so read the guarantee in full, ask for a cap and a release date in writing, and take independent legal advice before you sign.

There's still a route to complain. The Financial Ombudsman Service can look at complaints from micro-enterprises and small businesses — those with turnover under £6.5 million and either a balance sheet under £5 million or fewer than 50 staff — and from individuals who personally guaranteed a loan to their own business on or after 1 April 2019.

Negotiating is normal. Common outcomes are a guarantee capped at a percentage of the loan, a guarantee that reduces as the balance falls, or business assets offered as security instead. If you're asked to guarantee a loan to a company you don't control, such as a family member's business, be especially careful: you take on the risk without any say in how the company is run.

The Growth Guarantee Scheme

The Growth Guarantee Scheme (GGS) is the government's main loan guarantee for smaller firms. It's run by the British Business Bank, the government's economic development bank, through a network of accredited lenders that includes high street banks, challenger banks, asset finance and invoice finance providers. The government guarantees 70% of the outstanding balance to the lender if the loan goes bad, which lets lenders say yes to viable businesses that don't have enough security for a normal loan.

What it covers. GOV.UK lists term loans, overdrafts, asset finance, invoice finance and asset-based lending. Each accredited lender decides which of these it offers and sets its own minimums; Virgin Money, for example, sets a £30,000 minimum for GGS term loans.

Who qualifies. Your business must trade in the UK, generate more than 50% of its turnover from trading activity, be viable and not be a business in difficulty or in insolvency proceedings. GOV.UK's scheme page (published June 2026) lists a turnover limit of £45 million. Banks, insurers, public-sector bodies, state schools and some fossil-fuel extraction businesses are excluded, and the support counts towards your business's subsidy limits.

The July 2026 changes. On 13 July 2026 HM Treasury announced a major expansion of the scheme: the maximum term rising from six years to 10 years for loans of up to £1.1 million, the turnover ceiling rising from £45 million to £54 million, and an extra £2 billion of lending a year by 2028/29. The announcement didn't give a start date for the longer terms and higher turnover limit, so ask your lender whether they're live yet.

What it doesn't do. The guarantee protects the lender, not you. You owe 100% of the debt, the lender still runs its normal credit checks, and rates are set by each lender. A GGS loan can cost more than an ordinary secured loan, because the lender is taking more risk.

To apply, you go to an accredited lender, not to the British Business Bank. Ask your own bank first; if it isn't accredited or says no, the British Business Bank publishes the list of accredited GGS lenders on its website.

How banks decide: eligibility and what they check

Every lender has its own criteria, but the questions behind them are the same: can the business afford the repayments, and what happens if it can't?

Basic eligibility. NatWest's published criteria are typical: you must be 18 or over, a director (or owner) of the business, not bankrupt and without a County Court Judgment, and have a business current account. Many lenders want at least one or two years of trading for an unsecured loan; very new businesses often find a Start Up Loan easier.

Affordability. The lender looks at your accounts, bank statements and management figures to see whether cash coming in comfortably covers existing debts plus the new repayment. For larger loans it may ask for a cash flow forecast and look at how many times your profit covers the annual debt payments. A forecast that only works if sales jump straight away is a red flag.

Credit history. Lenders check the business's credit file and, for smaller companies and sole traders, the directors' or owner's personal files too. Late payments to suppliers, unpaid tax, County Court Judgments and frequent searches all count against you.

Consistency. NatWest warns that if the turnover you state doesn't match what flows through your account, your application may be referred or declined, and that your details at Companies House should be up to date. Overdue accounts or confirmation statements at Companies House are an easy reason for a lender to pause.

How to apply for a small business loan

Applying for a small business bank loan

1. 1

   Work out exactly what you need

   Cost the project, add a buffer, and pick the product that matches it: term loan, asset finance, overdraft or invoice finance.

2. 2

   Check your credit files and filings

   Check your personal and business credit files and make sure your accounts and confirmation statement are filed on time.

3. 3

   Get an eligibility check or indicative quote

   Most banks offer a soft-search eligibility check that doesn't affect your credit score. Compare APR, total payable and fees for the same amount and term.

4. 4

   Prepare your documents

   Recent accounts, 3–6 months of business bank statements, management accounts if you have them, and a cash flow forecast for larger loans.

5. 5

   Apply and answer questions

   Apply online or through a relationship manager. For larger loans, expect questions about your forecast and security.

   Tip: Ask whether the loan can be offered under the Growth Guarantee Scheme if you're short of security.

6. 6

   Review the offer and any guarantee

   Read the facility letter, the security documents and any personal guarantee in full. Take independent legal advice on guarantees.

If you're turned down: the Bank Referral Scheme

Being refused by one bank doesn't mean no lender will say yes. Since November 2016 the government's Bank Referral Scheme has required nine of the UK's biggest banks to offer to pass on the details of small businesses they turn down for finance. With your consent, your details go to one of three government-designated platforms: Alternative Business Funding, Funding Options or Funding Xchange. They share an anonymised version with alternative lenders, who contact you if they're interested.

HM Treasury's July 2026 statistics show more than 130,000 businesses referred and 6,905 deals completed by 31 March 2026, worth over £161.7 million in total, with an average deal of £23,430. That's a low conversion rate, so treat the scheme as one route among several, not a guarantee. The government consulted on improving it in late 2025, and in its May 2026 response asked the finance industry to submit joint proposals by 18 December 2026.

Whatever route you take, first ask the bank why it said no. Common reasons — weak affordability, a thin credit file, overdue filings, or asking for the wrong product — can often be fixed in a few months. Then decide whether to strengthen the application and reapply, try a smaller amount, look at asset or invoice finance secured on what you already have, or look beyond debt at small business grants.

Regulation, complaints and your protections

Whether a business loan is regulated depends on who borrows and how much. Credit of £25,000 or less to a sole trader, or to a partnership of two or three partners where not all partners are companies, is generally regulated consumer credit. That brings rules on information, affordability, cooling-off and early settlement. Above that amount, a loan made wholly or mainly for business purposes is usually exempt, and loans to limited companies are generally outside consumer credit rules altogether.

Even where a loan isn't regulated, the Financial Ombudsman Service can consider complaints from micro-enterprises and small businesses about how a bank treated them, such as how it handled an application, a guarantee or financial difficulty. Complain to the lender first; if you're unhappy with the final response, or it takes too long, you can go to the ombudsman.

If you fall behind, talk to the lender early. Most banks would rather agree a payment holiday or a restructured term than enforce security. Missing payments without contact damages both your business and personal credit and, if you've signed a guarantee, can lead the lender to call on it.

Common mistakes to avoid

Borrowing short for long-term assets. Funding equipment through an overdraft or credit cards means paying high rates and risking a facility being cut just when you need it. Use a term loan or asset finance.

Comparing monthly payments instead of total cost. A lower monthly payment over a longer term usually costs more overall. Compare APR and the total amount payable for the same amount and term.

Signing an unlimited guarantee without advice. An "all monies" guarantee can cover overdrafts and future borrowing you haven't thought about. Ask for a cap and take independent legal advice.

Applying to lots of lenders at once. Every full application leaves a hard search on your credit file. Use soft-search eligibility checks and a single, well-prepared application.

Ignoring the tax side. Interest on business borrowing is normally an allowable business expense, so it reduces your taxable profit; repaying the capital doesn't. Equipment bought with the loan can qualify for capital allowances. Your accountant can confirm how this works for your business structure.

Frequently asked questions

What interest rate will I pay on a small business loan in 2026?

It depends on the lender, the amount and your credit profile. On 9 October 2026, Barclays published representative APRs of 14.9% on £1,000 to £5,000, 11.2% on £5,001 to £15,000 and 8.5% on £15,001 to £25,000, and HSBC published 11.3% up to £10,000 and 8.6% above it. Bank of England Bank Rate was 3.75%. Your offer can be higher or lower.

Can I get a business loan without a personal guarantee?

Sometimes. Small unsecured loans from the big banks often don't need one, but many lenders ask company directors to guarantee larger loans, and asking is at the lender's discretion even under the Growth Guarantee Scheme. You can negotiate a capped guarantee, a time limit, or offer business assets as security instead. Always take independent legal advice before signing.

What is the Growth Guarantee Scheme?

It's a British Business Bank scheme that gives accredited lenders a 70% government guarantee on loans, overdrafts, asset finance and invoice finance of up to £2 million per business group. GOV.UK lists it for UK businesses with turnover up to £45 million. You stay 100% liable for the debt, and your main home can't be taken as security under the scheme.

What happens if my bank turns down my loan application?

If your bank is one of the nine designated under the Bank Referral Scheme, it must offer, with your permission, to pass your details to a government-designated finance platform: Alternative Business Funding, Funding Options or Funding Xchange. They match you with alternative lenders. You should also ask the bank why you were declined and check your business and personal credit files.

Are small business loans regulated by the FCA?

Loans of £25,000 or less to sole traders and partnerships of two or three partners are generally regulated consumer credit, with the full protections that brings. Loans to limited companies, and larger loans for business purposes, are mostly unregulated. Micro-enterprises and small businesses can still complain to the Financial Ombudsman Service about how a lender treated them.

How long does a business loan application take?

Small unsecured loans can be quick: NatWest says approved online applicants could have money within 24 hours, and some banks give an instant eligibility check. Larger, secured or government-backed loans usually take several weeks because the lender reviews accounts, forecasts and security. Having your last accounts, management figures and a cash flow forecast ready is what speeds things up most.
