Concerned about failing the ICR stress test for your Buy-to-Let mortgage? Learn how improving your Interest Coverage Ratio can unlock better mortgage terms, lower payments, and increase borrowing potential.
What Exactly is the Interest Coverage Ratio (ICR)
The Interest Coverage Ratio (ICR) is a crucial financial metric that mortgage lenders use to assess whether you can comfortably meet your mortgage interest payments. It compares your income to your interest payments and provides an indicator of your ability to afford monthly mortgage costs.
A higher ICR means your income can more comfortably cover your interest payments. For landlords applying for Buy-to-Let mortgages, a good ICR is essential for approval.
How is ICR Calculated?
ICR is calculated by dividing your annual rental income by your annual mortgage interest payments.
Formula:
ICR = Rental Income / Interest Payments
For instance:
Rental Income = £20,000
Interest Payments = £10,000
ICR = £20,000 ÷ £10,000 = 2
This means your rental income is double the amount needed to cover your interest payments, which signals to the lender that you are in a strong financial position.
How Lenders Use ICR?
Lenders typically require a minimum ICR of 125% for Buy-to-Let mortgages, meaning your rental income should be at least 1.25 times your annual mortgage interest payments.
For example:
Required ICR = 125%
Rental Income: £20,000
Interest Payments: £16,000
In this case, the borrower would meet the lender’s minimum ICR of 125%.
However, different lenders have varying criteria, and in some cases, a higher ICR may be required, particularly for self-employed or company director borrowers.
Why Does It Matter for Your Buy-to-Let Mortgage?
ICR is a key factor in securing mortgage approval, as it helps lenders gauge your ability to repay your mortgage’s interest, especially in Buy-to-Let scenarios. A higher ICR makes you more attractive to lenders, potentially securing better rates and terms.
If your ICR is higher than the lender’s minimum threshold (typically 1.5–2x), it shows financial strength and a lower risk of default, improving your chances of getting approved.
Top ICR Challenges and How to Overcome Them for Better Mortgage Terms
ICR stress testing can be a significant barrier for some landlords, but don’t let it hold you back—there are strategies to improve your chances of approval.
Some common issues borrowers face with ICR include:
Variable Income: For freelancers, self-employed individuals, and business owners, inconsistent income can lead to an unstable ICR.
High Debt Levels: Multiple debt repayments reduce the income available to cover mortgage interest, lowering your ICR.
Rising Interest Rates: A variable-rate mortgage increases monthly payments, potentially lowering your ICR and affecting your ability to pass the lender’s stress test.
Limited Documentation: Self-employed individuals or those with complex finances may find it harder to prove their income, which can impact ICR calculations.

Stress Testing: What Lenders Are Looking For
In addition to evaluating your ICR, lenders apply stress tests to assess your ability to handle changes in financial conditions, such as interest rate hikes or a decrease in income. Stress tests simulate scenarios that show whether you can still afford your mortgage under more difficult circumstances.
For example, a 2-3% rise in interest rates might be simulated. If your mortgage payments increase from £1,000 to £1,200, will you still be able to manage?
Lenders use stress testing to ensure that even in challenging financial conditions, you can meet your mortgage payments.
Simple Steps to Prepare for Stress Testing and Improve Your ICR
Opt for Fixed-Rate Mortgages: Fixed-rate mortgages offer payment stability, which helps pass stress tests.
Increase Income: Show additional sources of income, such as bonuses or rental income, to strengthen your financial profile.
Build a Financial Buffer: Save for emergencies and reduce existing debts to show you can weather financial storms.
Lower Loan-to-Value (LTV): A lower LTV ratio reduces risk, making it easier to pass stress tests.
Manage Your Debt-to-Income (DTI) Ratio: Keep your debt levels low to demonstrate your ability to handle more borrowing.
How Can Improving ICR Benefit You?
Improving your ICR can make a significant difference in your mortgage application. Here are a few benefits:
Better Mortgage Terms: A higher ICR increases your attractiveness to lenders, potentially securing better interest rates and more favourable terms.
Increased Borrowing Potential: With a higher ICR, lenders may offer you larger loans, enabling you to purchase better properties or expand your portfolio.
Reduced Financial Risk: A stronger ICR helps you manage financial fluctuations more effectively, reducing the chance of default.

Real Limited Company Mortgage Success Stories
Case Study: Helping a Company Director Overcome ICR Issues to Expand His Buy-to-Let Portfolio
👨💼 Client Profile:
Gareth, a property landlord based near London, had built up an impressive portfolio of 14 rental properties. His portfolio included a mix of single lets, HMOs, and properties held both in his personal name and through a limited company.
⚠️ The Challenge:
Despite strong rental yields and a solid track record, Gareth’s current lenders were limiting how much he could borrow due to high ICR stress testing. The borrowing shortfall made it impossible for him to move forward with his next property purchase.
🔍 My Solution:
I sourced specialist lenders who understood Gareth’s needs and were prepared to offer above-average lending based on the rental income, using lower ICR stress rates. This gave him the borrowing flexibility his existing lenders couldn’t provide. I also worked closely with his accountant to ensure the setup was tax-efficient and aligned with his long-term investment goals.
✅ Outcome:
Gareth successfully refinanced two existing properties through a limited company mortgage, releasing enough capital to proceed with the purchase of his 15th buy-to-let property. With a scalable structure now in place, he’s well positioned to continue growing his portfolio without the previous borrowing constraints.
💬 Client Testimonial:
“I was hitting a wall with mainstream lenders and couldn’t grow my portfolio any further. Lyndsey not only understood the problem, she gave me a clear strategy to move forward. Thanks to her help, I’ve now unlocked more borrowing and bought my next property.”
— Gareth J., Portfolio Landlord, London
