A complete guide to key UK loan and lending terms. Understand how loans work, what affects approval, and how borrowing impacts your credit score.
Understanding loans involves more than just borrowing money. Lenders assess your financial situation, credit history, and affordability before making a decision.
This glossary explains the key UK loan terms used throughout the borrowing process — from eligibility and application through to repayment and closure.
Eligibility
Eligibility refers to whether you meet a lender’s basic requirements to apply for a loan.
This may include your income, credit history, employment status, and existing financial commitments.
Pre-Approval
Pre-approval is an indication from a lender that you may be eligible for a loan based on an initial assessment of your financial information.
It is not a final decision, but it provides an estimate of the loan amount and terms you may be offered if you proceed with a full application.
Pre-approval is often based on a soft credit check and does not guarantee acceptance.
Broker
A broker is a service that matches borrowers with lenders based on eligibility and financial profile. Brokers do not usually lend money directly and may earn commission or charge fees depending on the arrangement.
Open Banking
Open Banking allows lenders to securely access your financial data (with your permission), such as income and spending.
It is commonly used to improve affordability checks and speed up loan decisions.
Affordability Check
An affordability check is an assessment used by lenders to determine whether you can realistically afford to repay a loan.
It reviews your income, expenses, existing debts, and financial commitments to ensure repayments are sustainable.
Some lenders use Open Banking or financial data sharing (with your permission) to improve accuracy.
Credit Check
A credit check is carried out when you apply for a loan to assess your credit history and repayment reliability.
A soft check may be used for eligibility checks and does not affect your credit score. A hard check occurs during a full application and may temporarily impact your score.
How Much Does a Loan Affect Your Credit Score?
Loan
A loan is money you borrow from a lender that must be repaid over time, usually with interest.
Loans can be used for purposes such as buying a car, home improvements, or consolidating debt. Repayments are usually made monthly over an agreed term.

Unsecured Loan
An unsecured loan is borrowing that does not require assets as security.
Approval is based on credit score, income, and affordability. Interest rates may be higher due to increased lender risk.
Secured Loan
A secured loan is backed by an asset such as your home or car.
This may allow higher borrowing or lower interest rates, but the asset may be at risk if repayments are not maintained.
Guarantor Loan
A guarantor loan requires another person to agree to repay the loan if you cannot.
These are often used by borrowers with limited or poor credit history.
Debt Consolidation
Debt consolidation combines multiple debts into a single loan with one monthly repayment.
It may simplify repayments and potentially reduce monthly costs depending on interest rates and term.
Payday Loan
A payday loan is a short-term loan usually repaid in full on your next payday.
These are typically small, high-cost loans intended for emergency use and should be used carefully.
High Cost Short Term Credit (HCSTC)
High Cost Short Term Credit refers to short-term borrowing with high interest rates or fees.
Payday loans are a common example and are strictly regulated in the UK due to their cost and risk.
Interest Rate
The interest rate is the percentage charged for borrowing money.
It determines how much extra you repay on top of the loan amount and may be fixed or variable.
APR / APRC
APR shows the total yearly cost of borrowing, including interest and standard fees.
APRC is mainly used for secured lending and includes additional costs such as arrangement fees, giving a fuller cost picture over the loan term.
Representative Example
A representative example shows the typical cost of a loan, including interest and fees, that at least 51% of accepted customers are expected to receive.
It helps borrowers understand likely costs, though actual rates may vary based on your credit profile.
Broker Fees
Broker fees are charges that may be applied by a broker for arranging or introducing a loan.
These must be clearly disclosed before you proceed.
Early Repayment Charges
Early repayment charges may apply if you repay your loan early.
Late Payment Fees
Late payment fees are charged when a repayment is missed or delayed.
They may also negatively affect your credit score and lead to further action if not resolved.
Guaranteed Rate
A guaranteed rate is an interest rate confirmed by a lender that you will receive should your loan be approved. It means the rate will not change before the loan is finalised, provided your application details remain accurate.
However, it does not guarantee that your loan will be approved.
Loan Term
A loan term is the length of time you have to repay a loan in full.
Shorter terms mean higher monthly repayments but lower total interest, while longer terms reduce monthly payments but increase overall cost.
Credit Score Impact
A loan can affect your credit score in different ways.
A hard credit check may cause a small temporary dip, while consistent repayments can help build positive credit history over time.
Arrears
Arrears refer to missed or overdue loan payments.
Being in arrears can lead to fees, credit score damage, and potential further action if not resolved.
Settlement Figure
A settlement figure is the total amount required to fully repay your loan early.
It may include remaining balance, interest, and any early repayment charges.
