Business Loans and Debt Finance: How They Work

Business loans and other forms of debt finance allow companies to raise capital without giving up ownership in the business.

Instead, a lender provides funding that the business agrees to repay, normally with interest, over an agreed period.

Debt financing can be used for everything from improving working capital and purchasing equipment to expanding into new locations or business funding for buying a business.

However, taking on debt creates an ongoing financial commitment, so it is important to understand how business loans work, the different forms of debt funding available and what lenders will consider before agreeing finance.

This guide explains debt finance for UK businesses, including the main types of business loans, how repayments work, secured and unsecured borrowing, costs and when debt funding may be appropriate.

What Is Debt Finance?

Debt finance is money borrowed by a business that must be repaid to the lender according to agreed terms.

The business receives capital upfront or access to an agreed facility and usually pays:

• The amount originally borrowed
• Interest
• Any applicable fees

Unlike equity finance, the lender does not normally receive shares in the business.

This means the existing owners can retain their ownership, but the company must continue meeting its repayment obligations.

Common forms of debt finance include:

• Business loans
• Commercial loans
• Overdrafts
• Revolving credit facilities
• Asset finance
• Invoice finance
• Working capital loans
• Acquisition finance

Debt and equity are the two broad categories into which most external business finance falls. With debt, capital is borrowed and repaid. With equity, capital is raised by giving an investor an ownership stake in the business.

What Is a Business Loan?

A business loan is a form of debt finance where a lender provides money to a business and the borrower repays it over an agreed period.

Repayments normally include both:

Capital – the amount originally borrowed.

Interest – the cost charged by the lender for providing the finance.

For example, if a business borrows £100,000, it will usually repay more than £100,000 over the life of the loan once interest and any fees are included.

Business loans can be:

• Short, medium or long term
• Secured or unsecured
• Fixed or variable rate
• Repaid monthly or according to another agreed schedule
• Used for a wide range of commercial purposes

The precise structure depends on the lender, the business and what the funding is being used for.

What Can Business Loans Be Used For?

Business loans are relatively flexible and may be used to fund:

• Business expansion
• Purchasing equipment
• Buying stock
• Recruiting employees
• Opening new premises
• Marketing
• Working capital
• Refinancing existing debt
• Acquiring another company
• Investing in technology
• Managing seasonal cash flow

The purpose of the funding will influence which type of business finance is most appropriate.

For example, a five-year business loan may make sense for a long-term expansion project, whereas a revolving credit facility may be better suited to a temporary working capital requirement.

How Does Debt Finance Work?

A typical debt finance arrangement follows several stages.

1. The business identifies a funding requirement

The company works out:

• How much money it needs
• What the money will be used for
• How long the funding is required
• How repayments will be supported

For example, an established company may decide it requires £300,000 to purchase equipment and increase production capacity.

2. The business approaches a lender

The lender will assess the company and the proposed use of the funding.

This could involve reviewing:

• Accounts
• Profitability
• Cash flow
• Bank statements
• Existing borrowing
• Credit history
• Available security
• Financial forecasts

3. The lender assesses affordability

The lender needs to be confident that the business can support the proposed financial commitment.

A profitable company does not automatically qualify for borrowing.

The lender will also look at whether sufficient cash is generated to make repayments.

4. Funding terms are agreed

If the application is approved, the lender may set out terms including:

• Loan amount
• Interest rate
• Loan term
• Repayment schedule
• Security
• Personal guarantees
• Financial covenants
• Fees

5. The business receives the funds

Depending on the product, the money may be provided as a lump sum or made available through a flexible facility.

6. Repayments begin

The business then makes repayments according to the agreement.

Failure to meet those obligations can have serious financial consequences and may allow a lender to enforce security or guarantees where applicable.

What Are the Different Types of Debt Finance?

Debt funding is broader than a conventional business loan.

Different products are designed for different commercial needs.

Term Loans

A term loan provides a fixed amount of money that is repaid over a set period.

For example:

Loan amount: £250,000
Term: 5 years
Repayment: Monthly
Interest: Fixed or variable depending on the agreement

Term loans are commonly used for:

• Expansion
• Acquisitions
• Large investments
• Refurbishments
• Equipment
• Longer-term projects

They can provide certainty because the repayment period is agreed in advance.

Business Overdrafts

An overdraft allows a business bank account to fall below zero up to an agreed limit.

Unlike a term loan, the business normally only uses the amount it needs.

This can make overdrafts useful for:

• Temporary cash flow shortages
• Seasonal expenditure
• Unexpected costs
• Timing differences between customer and supplier payments

They are generally better suited to short-term requirements than funding major long-term investments.

Revolving Credit Facilities

A revolving credit facility allows a business to borrow, repay and borrow again up to an agreed limit.

It works differently from a conventional term loan because the entire amount does not necessarily need to be drawn at once.

For example, a business could have a £500,000 facility but only use £150,000 when additional working capital is required.

As the money is repaid, the facility can potentially be used again during the agreed term.

Asset Finance

Asset finance is debt funding linked to assets such as:

• Machinery
• Vehicles
• Equipment
• Technology

Instead of paying the full purchase price upfront, the cost is spread over an agreed period.

Asset finance can help preserve working capital while still allowing the company to invest in assets required to operate or grow.

Invoice Finance

Invoice finance allows eligible businesses to raise funds against unpaid customer invoices.

This can be particularly useful where there is a substantial delay between completing work and receiving payment.

Common types include:

• Invoice factoring
• Invoice discounting

Invoice finance is primarily a working capital and cash flow tool rather than a conventional lump-sum loan.

Read Invoice Finance: Factoring and Invoice Discounting Explained for a full guide.

Working Capital Loans

Working capital finance is designed to support the everyday operating requirements of a business.

It can help fund:

• Payroll
• Stock
• Suppliers
• Rent
• Seasonal requirements
• Short-term cash flow pressure

Working capital facilities may be structured as loans, overdrafts, revolving credit or other forms of finance.

Acquisition Finance

Debt finance can also be used to help buy an existing business.

An acquisition lender may assess the financial performance of the target company as part of the funding decision.

Relevant factors can include:

• EBITDA
• Cash flow
• Existing debt
• Customer concentration
• Working capital
• Management structure
• Purchase price
• Buyer contribution

Acquisition debt may be combined with other funding sources such as buyer capital, seller finance or deferred consideration.

Secured vs Unsecured Business Loans

Business loans can be either secured or unsecured.

Secured business loans

Secured borrowing uses assets or other security to support the loan.

Potential security could include:

• Commercial property
• Equipment
• Machinery
• Vehicles
• Other business assets

Providing security gives the lender additional protection if the company cannot repay the debt.

This may allow larger amounts to be borrowed or different terms to be offered.

However, the assets used as security may be at risk if the borrower fails to meet the agreement.

Unsecured business loans

Unsecured business loans do not normally take security over a specific business asset.

Instead, the lender places greater emphasis on:

• Cash flow
• Financial strength
• Creditworthiness
• Trading history

Some unsecured loans may still require directors to provide personal guarantees.

Read Secured vs Unsecured Business Finance: Key Differences for a full comparison.

Fixed vs Variable Interest Rates

The interest charged on business finance may be fixed or variable.

Fixed interest rate

A fixed rate remains unchanged for the agreed fixed-rate period.

This can make repayments more predictable.

For example, if the business knows its repayment is £4,000 per month throughout a fixed-rate term, this can make cash flow planning easier.

Variable interest rate

A variable rate can change over time.

The interest rate may be linked to an underlying benchmark or otherwise vary according to the lending agreement.

This means repayments or interest costs may rise or fall during the term.

Businesses using variable-rate debt should consider whether they could still afford the borrowing if rates increased.

How Much Can You Borrow With a Business Loan?

There is no universal maximum business loan amount.

The amount available depends on the lender, finance product and strength of the borrower.

Factors may include:

• Turnover
• Profitability
• EBITDA
• Cash flow
• Existing borrowing
• Creditworthiness
• Trading history
• Available security
• Funding purpose

A lender is unlikely to assess borrowing capacity simply as a percentage of revenue.

The key issue is whether the proposed debt can reasonably be supported.

For example, two businesses may both generate £3 million in annual sales.

One may produce £600,000 of EBITDA with limited existing debt, while the other generates £100,000 and already has significant borrowing.

Their debt capacity would be very different.

What Do Lenders Look at Before Offering a Business Loan?

Business finance providers assess a range of factors.

Financial performance

Lenders may review historic accounts to understand:

• Revenue
• Gross margin
• Profit
• EBITDA
• Assets
• Liabilities

Consistent financial performance can give the lender greater confidence in the business.

Cash flow

Cash flow is critical because loan repayments are made with cash rather than accounting profit.

A lender will want confidence that the company generates enough cash to service the debt.

Existing borrowing

The lender will normally consider how much debt the business already has.

Additional borrowing needs to remain affordable after existing repayments are taken into account.

Credit history

The financial history of the company, and potentially its directors, can influence both approval and pricing.

Security

Where secured finance is being requested, the lender may assess the value and quality of the assets available as security.

Purpose of the loan

The business should clearly explain why the money is required.

A defined commercial purpose is easier to assess than a vague request for additional cash.

Management experience

For larger or more complex transactions, lenders may also consider whether the management team has the experience required to deliver the proposed plan.

What Does a Business Loan Cost?

The cost of debt finance includes more than the interest rate.

Possible costs include:

• Interest
• Arrangement fees
• Valuation fees
• Legal fees
• Broker fees
• Monitoring fees
• Early repayment charges

A business should therefore consider the total cost of borrowing.

For example, two lenders could offer the same £250,000 loan at different interest rates but with very different fees and repayment terms.

The cheapest headline rate may not produce the lowest overall cost.

Read Business Funding Costs: Interest Rates, Fees and Total Cost for more information.

What Is a Personal Guarantee?

A lender may ask directors or shareholders to provide a personal guarantee.

A personal guarantee can make the guarantor personally responsible for some or all of the company's debt if the business cannot repay it, subject to the wording of the agreement.

Before agreeing to one, directors should understand:

• The amount covered
• Whether liability is capped
• When the guarantee can be enforced
• Whether it applies to one loan or several facilities
• Whether it can be released
• What assets may ultimately be at risk

Independent legal advice may be appropriate before entering into a personal guarantee.

Advantages of Business Loans and Debt Finance

Debt finance can offer several advantages.

You retain ownership

Borrowing money does not normally require the owners to give shares to the lender.

This means existing shareholders retain the future value of the company.

Repayments can be planned

With a structured loan, businesses can often forecast repayments and incorporate them into financial planning.

Funding can support growth

A company may be able to make an investment sooner rather than waiting until it has accumulated enough cash internally.

Different facilities suit different purposes

Businesses can choose from products designed for:

• Working capital
• Assets
• Acquisitions
• Expansion
• Short-term liquidity
  
  

Established businesses can use their track record

Historic profitability and cash flow can help established companies demonstrate their ability to support borrowing.

Disadvantages of Debt Finance

Debt also creates risks and obligations.

The loan must be repaid

Repayments usually continue even if trading performance weakens.

Interest increases the cost

The business ultimately pays more than the original amount borrowed.

Cash flow can come under pressure

High repayments can reduce the amount of cash available for operations and investment.

Security may be required

Assets used as security may be at risk if the business cannot repay.

Personal guarantees may be requested

This can potentially expose directors or shareholders to personal financial liability.

Borrowing can reduce future flexibility

Taking on substantial debt now may limit the amount of additional finance available later.

Debt Finance vs Equity Finance

Debt and equity finance solve the same underlying problem — providing additional capital — but they do so in very different ways.

Debt may suit an established business with predictable cash generation that wants to retain ownership.

Equity may suit a business requiring substantial growth capital where fixed repayments would create too much pressure.

Some businesses use a combination of both.

When Is Debt Finance a Good Option?

Debt funding may make sense where:

• The business generates stable cash flow
• The purpose of the borrowing is clear
• The investment is expected to produce a commercial return
• Repayments remain affordable
• Owners want to retain equity
• The business has sufficient financial headroom

For example, a profitable manufacturer may decide to borrow £300,000 to purchase machinery that increases production capacity.

If the company can comfortably service the finance and expects the new capacity to increase profits, debt may be commercially sensible.

When Might Debt Finance Be Less Suitable?

Borrowing may be less appropriate where:

• Cash flow is highly unpredictable
• The business is already heavily indebted
• There is no clear repayment strategy
• The company is consistently loss-making
• The funding requirement is highly speculative
• Additional repayments would leave little financial headroom

In those circumstances, another form of business funding may be more appropriate.

How to Apply for a Business Loan

The precise application process varies by provider, but generally involves:

Calculate the amount required

Understand exactly how much money is needed.

Define the purpose

Be clear about what the funding will achieve.

Review your financial position

Assess:

• Profit
• Cash flow
• Existing borrowing
• Repayment capacity
  
  

Prepare supporting information

This may include:

• Annual accounts
• Management accounts
• Bank statements
• Forecasts
• Existing loan schedules
  
  

Approach suitable lenders

Not every lender is appropriate for every business or funding requirement.

Compare offers

Review the:

• Interest rate
• Fees
• Term
• Security
• Guarantees
• Total cost
• Flexibility

The British Business Bank advises that lenders typically require businesses to demonstrate both the intended purpose of borrowing and their ability to repay it.

What Happens If a Business Loan Is Rejected?

A declined loan application does not necessarily mean the business cannot obtain finance from another provider.

Different lenders have different:

• Credit policies
• Sector preferences
• Minimum criteria
• Risk appetite
• Security requirements

However, it is important to understand why the application was rejected.

Common reasons can include:

• Poor cash flow
• Weak profitability
• High existing debt
• Limited trading history
• Credit problems
• Insufficient security
• An unrealistic borrowing request

Applying repeatedly without addressing an underlying issue may not improve the situation.

Some businesses declined by participating major banks may also be offered referral through the UK's Bank Referral Scheme to alternative finance platforms.

Read Why Business Funding Applications Are Rejected for more information.

Using Debt Finance to Buy a Business

Debt finance is commonly considered when acquiring an established company because the target business already has a financial history that a lender can assess.

Unlike funding a startup, the lender may be able to review:

• Historic profitability
• EBITDA
• Cash generation
• Assets
• Customer base
• Existing liabilities

This information can help determine whether the target business can support acquisition debt after completion.

A typical transaction might combine:

Purchase price: £1,000,000

• Buyer capital: £250,000
• Acquisition debt: £500,000
• Deferred consideration: £250,000

The exact funding structure depends on the company, the buyer and the transaction.

Importantly, a lender will not simply provide debt because the purchase price supports the amount requested. The business must be capable of servicing the borrowing after the acquisition.

For a detailed look at this specific funding strategy, read Debt Funded Purchase: How Does It Work?.

Is Debt Finance Right for Your Business?

Business loans and debt finance can give companies access to capital without giving away ownership.

That can make borrowing an attractive way to fund expansion, assets, working capital or an acquisition.

However, debt should only be taken on where the business has a clear reason for borrowing and a realistic ability to meet its commitments.

Before agreeing finance, consider:

• Why you need the money
• How much you actually need
• Whether repayments are affordable
• The total cost of borrowing
• Security requirements
• Personal guarantees
• How the debt affects future funding capacity
• What happens if trading performance weakens

The best debt structure is not necessarily the one that provides the largest loan.

It is the one that provides enough capital to achieve the business objective while leaving sufficient financial headroom for the company to operate successfully.
