Mortgage approvals are falling – how to maximise your chances

Mortgage approvals have been moving in the wrong direction in recent months. When approvals fall, it often means lenders are being more selective, affordability checks are becoming more detailed, and small issues that might previously have been overlooked can start to matter.

This guide explains the main factors that influence mortgage decisions and sets out practical steps you can take to strengthen how your application is presented.

Why mortgage approvals can become harder to secure

Even when interest rates stabilise, lenders may still tighten their approach because of:

• Affordability pressure: higher living costs and mortgage payments can make budgets look tighter.
• More cautious risk appetite: lenders may review how they assess income, spending and credit behaviour.
• Increased scrutiny of evidence: documentation quality and consistency can become more important.
• Market uncertainty: lenders may focus more on resilience (how you’d cope if circumstances change).

The result is that two borrowers with similar incomes can see different outcomes depending on credit history, deposit size, employment pattern and how clearly their finances are evidenced.

What factors affect your chances of mortgage approval?

1) Credit score and credit history

Lenders use credit information to understand how you manage borrowing. While you’ll often hear “credit score”, lenders typically look at the underlying credit history too.

Key points that can influence decisions include:

• On-time payment behaviour (credit cards, loans, and other commitments)
• Whether any accounts have been missed, defaulted or sent to collections
• How much of your available credit you use (credit utilisation)
• Whether your credit file is stable (frequent new accounts can raise questions)

If you’ve had issues in the past, the direction of travel matters. Evidence of improvement over time can be more persuasive than a single snapshot.

2) Income and affordability

Mortgage affordability is not just about your salary figure. Lenders consider whether your income is likely to remain stable and whether your monthly commitments leave enough headroom.

Common affordability considerations include:

• Your regular income type (permanent employment, contract work, overtime, bonuses)
• How predictable your income is
• Your existing monthly outgoings (loans, credit cards, childcare, and other regular commitments)
• Your ability to cover the mortgage payment alongside day-to-day spending

If your finances are stretched, even a small change—such as a new commitment or an increase in credit card balances—can affect how your application is assessed.

3) Loan-to-Value (LTV)

LTV compares the mortgage amount to the property’s value. In general, a lower LTV can be helpful because it reduces lender risk.

Practical implications:

• A larger deposit can improve your position.
• A higher LTV may still be possible, but it can lead to more scrutiny and potentially less flexibility.

It’s also worth remembering that the property value used for LTV is tied to the lender’s valuation process.

4) Employment stability

Lenders want confidence that income will continue. That usually means:

• A consistent employment history
• No unexplained gaps
• Clear explanations where circumstances have changed

Frequent job changes or short-term employment can lead to additional questions, particularly if income is variable.

5) How the application is evidenced

Two applicants can have similar finances, but one application may be easier for a lender to verify.

Lenders typically expect documentation that is:

• Accurate and up to date
• Consistent across payslips, bank statements and application details
• Clear about any unusual items (for example, large deposits or irregular income)

When information is unclear, lenders may request further evidence or treat certain figures more cautiously.

How to strengthen your mortgage application

Below are practical steps that can improve how your application is assessed.

1) Review your credit file and fix avoidable issues

Start by checking your credit report for errors and outdated information.

Consider:

• Correcting incorrect addresses, accounts or payment statuses
• Ensuring all accounts are up to date
• Reducing credit card balances where possible to improve credit utilisation

If you’re planning to apply soon, avoid making major credit changes unless you understand the likely impact.

2) Create a realistic plan to reduce debt pressure

Lenders look at your overall monthly commitments. If you can reduce debt payments before applying, it can help affordability.

Approaches that often work in practice:

• Target higher-interest debts first
• Build a repayment routine that supports consistent on-time payments
• Avoid taking on new credit that increases monthly outgoings

Even small reductions in monthly payments can make a difference to affordability calculations.

3) Tighten your household budget before the application

If your spending is close to the limit, lenders may see less headroom.

Try:

• Identifying discretionary spending you can reduce temporarily
• Ensuring regular bills are paid on time
• Avoiding new commitments that increase monthly outgoings

The goal is not to live unreasonably—it’s to present a stable, credible budget.

4) Keep income stable and explain changes clearly

If your employment or income has changed, ensure the application reflects it accurately.

Where relevant, be prepared to explain:

• Short employment gaps
• Career changes
• Any periods of reduced income

If your income includes elements such as overtime or commission, make sure the figures you provide match how lenders will assess them.

5) Improve your LTV position where possible

If you can increase your deposit, it can strengthen your application.

Ways people often improve LTV include:

• Saving additional funds over time
• Using accessible savings for the deposit (where appropriate)
• Reviewing whether the purchase price and deposit structure can be adjusted

If you’re close to a key LTV threshold, even modest changes can affect how your application is considered.

6) Prepare your mortgage application documents carefully

A strong application is one that is easy to verify.

Focus on:

• Using the correct figures and ensuring they match supporting documents
• Keeping records of any unusual transactions
• Ensuring statements and payslips are complete and legible

If you have irregular income, the application should clearly show how it’s earned and how it will be assessed.

7) Avoid unnecessary credit applications in the run-up

Applying for additional credit can introduce new hard searches and new commitments.

In the period leading up to a mortgage application, it’s usually best to:

• Avoid non-essential credit applications
• Keep existing accounts managed and up to date
• Plan any credit changes well in advance

8) Consider whether government schemes or shared ownership options apply

Some buyers may be able to use specific schemes to support affordability or deposit requirements.

Examples include:

• First Homes (for eligible buyers purchasing qualifying homes)
• Shared Ownership and Affordable Homes Programme (buying a share of a property and paying rent on the remainder)

Scheme rules can be detailed and vary by circumstances and location, so it’s important to check whether your situation fits.

What to do if you’re worried about approval

If approvals are falling, it can be tempting to assume the outcome is out of your hands. In many cases, however, the decision comes down to how lenders interpret risk based on your credit behaviour, affordability evidence, deposit position and employment stability.

Strengthening the areas you can control—credit file accuracy, debt pressure, budget stability, deposit/LTV and document quality—can improve the chances that your application is assessed favourably.
