What is a business loan and how does it work?

Business Finance Guide

A business loan is one of the most widely used forms of funding for UK small businesses, but the way they work has changed significantly in recent years. High street banks are no longer the only option, and for many businesses they are not even the best one.

This guide explains exactly what a business loan is, how repayments and interest work, the different types available, and how to give yourself the best chance of being approved.

What Is a Business Loan?

A business loan is a fixed amount of money borrowed from a lender that is repaid over an agreed period, typically with interest. The lender provides the capital upfront and you repay it in regular instalments, usually monthly, over a term that can range from a few months to several years.

Business loans can be secured or unsecured. A secured loan requires an asset such as property or equipment as collateral. An unsecured loan does not require security, though lenders may ask for a personal guarantee from a director instead.

Business loans are best suited to businesses that need a defined lump sum for a specific purpose and have the cash flow to meet fixed monthly repayments comfortably.

Secured vs Unsecured Business Loans

The distinction between secured and unsecured lending matters both for how much you can borrow and what happens if you cannot repay.

Secured

Secured Business Loan

Backed by an asset such as commercial property, equipment, or stock. Because the lender has security to fall back on, you can typically borrow more at lower interest rates. However, the asset is at risk if you default.

Unsecured

Unsecured Business Loan

No asset is required as collateral. Lenders rely on the creditworthiness of the business and its directors. Rates tend to be higher, but the application process is faster and more accessible for most SMEs.

How Interest Works

Business loan interest is typically expressed as an annual percentage rate (APR) or a simple interest rate. The rate you receive will depend on your credit profile, trading history, loan amount, and the lender you use.

Some lenders, particularly alternative and specialist lenders, use a factor rate instead of an annual interest rate. This is a fixed multiplier applied to the loan amount, meaning the total repayment is agreed upfront and does not change over the life of the loan regardless of how quickly you repay.

Feature High Street Bank Loan Alternative Lender Loan
Typical interest rate Lower, from around 4% Higher, reflects faster access
Approval speed Weeks to months 24 to 72 hours
Trading history needed Usually 2 to 3 years Often 6 months or less
Credit requirements Strict More flexible
Application process Lengthy and document heavy Streamlined, often online
Loan amounts £25,000 and above typically From £1,000 upwards

What Can a Business Loan Be Used For?

One of the advantages of a business loan over more specific finance products is flexibility. Most lenders allow funds to be used across a wide range of business purposes.

Purpose 01

Working Capital

Cover day to day operating costs, manage cash flow gaps, or bridge the period between paying suppliers and receiving payment from clients.

Purpose 02

Growth and Expansion

Open a new location, hire additional staff, expand into new markets, or invest in marketing to scale the business.

Purpose 03

Equipment and Technology

Purchase machinery, vehicles, software, or IT infrastructure without draining your working capital reserves.

Purpose 04

Stock and Inventory

Buy stock in larger quantities to benefit from supplier discounts or prepare for a seasonal peak in demand.

Purpose 05

Refurbishment

Renovate premises, upgrade facilities, or invest in improvements that increase the value or capacity of your business.

Purpose 06

Refinancing Existing Debt

Consolidate multiple repayments into a single manageable loan, potentially at a better rate or over a more comfortable term.

  • High street banks can take weeks and still decline

What Do Lenders Look At?

Understanding what lenders assess helps you prepare a stronger application and improves your chances of approval at a competitive rate.

1

Trading history. Most lenders want to see at least six months of trading. The longer you have been operating, the more confidence a lender has in your ability to repay.

2

Business bank statements. Lenders use three to six months of statements to assess your cash flow, revenue consistency, and how you manage your finances day to day.

3

Credit history. Both business and personal credit profiles are considered. A clean history supports a stronger application, but many alternative lenders are willing to work with businesses that have imperfect credit.

4

Turnover and profitability. Lenders want to see that your business generates enough revenue to comfortably service the loan repayments alongside your existing outgoings.

5

Purpose of the loan. Being clear about what the money is for and how it will benefit the business shows a lender you have a considered plan rather than a short term cash need.
