What Is an Affordability Check? What Lenders Actually Look For
1st April 2026
When you apply for a loan, credit card, or mortgage in the UK, lenders carry out an affordability check to work out whether you can manage the repayments alongside your existing financial commitments.
This assessment looks at your income, outgoings, and existing debts to make sure the credit is suitable for your circumstances and won't cause financial hardship.
Understanding how affordability checks work can help you prepare better for the application process and feel more confident about what to expect.
What Is an Affordability Check?
An affordability check is an assessment lenders carry out to work out whether you can comfortably manage the repayments on a loan, credit card, or mortgage. It's not just about whether you earn enough money it's about understanding your full financial picture to see if taking on the credit makes sense for your circumstances.
This became a legal requirement following regulations introduced by the Financial Conduct Authority (FCA) The aim was to protect borrowers from taking on credit they couldn't realistically repay, and to encourage responsible lending across the industry.
Since 2014, FCA rules have required lenders to assess affordability before approving any form of credit, including personal loans, credit cards, and mortgages.
Every lender approaches affordability slightly differently, but they all follow the same core principle: they need to be satisfied that you can meet your repayments without experiencing financial difficulty.
Why Do Lenders Carry Out Affordability Checks?
Affordability checks protect both you and the lender.
For you, they help prevent taking on more debt than you can handle which could lead to missed payments, damage to your credit history, or mounting financial stress.
For lenders, these checks reduce the risk of lending to someone who might struggle to repay.
What's the difference between a credit check and an affordability check?
These two assessments are often confused, but they serve different purposes:
Credit Check | Affordability Check | |
What it looks at | Your borrowing history and credit score | Your current income, expenses, and debts |
Purpose | Assesses past financial behaviour | Determines whether you can manage new repayments |
When it happens | During a formal application | During a formal application |
Lenders carry out both assessments to get a complete picture of your financial situation. It's possible to have a strong credit history but still not pass an affordability check if your outgoings are too high relative to your income. The reverse is also true.
What Information Do Lenders Look At?
When you apply for credit, lenders gather information from several sources. Some details come directly from your application. Others may come from credit reference agencies Experian →, Equifax →, and TransUnion → or from your bank statements if you share them through Open Banking.
Here's what lenders typically consider.
Your income
Lenders want to know how much money comes in each month. This could include:
- Your salary
- Regular bonuses or overtime
- Benefits or pensions
- Income from self employment
If you have more than one income source, mention all of them it gives a fuller picture of your finances. Some lenders may ask for proof of income, such as recent payslips or bank statements. If you're self employed, you might need to provide tax returns or accounts.
Your monthly expenses and living costs
Lenders look at your regular monthly outgoings to understand what you're already spending. That includes:
- Rent or mortgage payments
- Council tax and utility bills
- Groceries and household expenses
- Childcare or school costs
- Transport costs, including car finance or travel passes
- Insurance policies
- Subscriptions and memberships
Some lenders will ask you to estimate these costs yourself. Others may use Open Banking data with your permission to get a more detailed view of your spending patterns.
Your existing credit commitments
Lenders will also look at any debts or credit agreements you already have, such as credit cards, other loans, store cards, or buy now pay later arrangements. They need to know how much you owe and what your monthly repayments are. Even if you're managing these comfortably now, lenders need to consider whether adding another repayment would stretch your budget too far.
If you're applying jointly with someone else like a partner or family member the lender will assess both of your incomes and outgoings together.
Your dependants
Lenders often ask how many people depend on your income, such as children or other family members you support. This helps them understand your financial responsibilities and what your household costs might realistically look like.
Your housing status
Whether you rent, own your home, or live with family can also be a factor. Homeowners with a mortgage have a significant monthly commitment, while renters have regular rent to pay. Living with family might mean lower outgoings, which could impact your affordability assessment.
How Do Lenders Decide If You Can Afford the Loan?
Once lenders have gathered your financial information, they calculate your disposable income the money left each month after covering essential expenses and existing debts. They then compare this to the monthly repayment on the loan you're applying for.
Most lenders want to see that your monthly loan repayment won't exceed 40–50% of your disposable income. If your disposable income is too low, they might decline the application or offer a smaller loan amount.
What is a stress test?
Some lenders also carry out a stress test during affordability checks. This means assessing whether you could still afford the repayments if your circumstances changed for example, if your income dropped or you faced an unexpected expense. Stress testing helps make sure you won't struggle with repayments if your financial situation shifts.
How the process works
1. You submit your application You give details about your income, outgoings, and existing debts.
2. The lender reviews your information They calculate your disposable income and compare it to the loan repayment.
3. They run a credit check Your credit history is reviewed alongside the affordability assessment.
4. A decision is made If everything looks manageable, your application may be approved. If not, it may be declined or the loan amount adjusted.
What Happens If You Don't Pass an Affordability Check?
If a lender decides the loan isn't affordable for you based on the information you've given, they'll decline your application. This can feel disappointing especially if you were counting on the funds but it's designed to protect you from taking on credit that could cause financial strain.
If this happens, it's worth taking a step back and reviewing your budget. Reducing some outgoings, paying down existing debts, or applying for a smaller amount could improve your position when applying with lenders in the future. Even with improved circumstances, approval depends on a full assessment of affordability and creditworthiness at the time of application.
It's also important not to make multiple applications in quick succession. Each full application typically involves a hard credit check, which leaves a mark on your credit file. Too many in a short space of time could make lenders more cautious.

How Can You Prepare for an Affordability Check?
If you're planning to apply for a loan, a few steps beforehand could give you the best chance.
Review your monthly budget and spending patterns
Before you apply, work out what you're spending each month. Add up essential costs like rent, bills, and food, then include subscriptions, transport, and debt repayments. This will help you understand how much disposable income you genuinely have and whether you can comfortably manage an additional repayment.
MoneyHelper's free budget planner → is a useful tool for this.
Check your credit report
Your credit history still plays a role in the overall lending decision. It's worth reviewing your credit report before you apply to make sure everything is accurate. If there are mistakes, you can ask the credit reference agency to correct them.

Consider what you actually need
It can be tempting to borrow the maximum amount a lender might offer, but think carefully about what you actually need. Borrowing less means lower monthly repayments, which could make the affordability check more straightforward and leave you with more breathing room in your budget.
Avoid big financial changes just before applying
If you're about to apply for a loan, try to avoid taking on new credit commitments or making large purchases on credit. Lenders will see these when they review your file, and they could affect how much disposable income you appear to have.
Using a soft search eligibility checker before applying can help you understand your chances without leaving a mark on your credit file.
