ℹ️ What is a Mortgage Stress Test? (UK)

Since 2014, UK mortgage lenders have been required by the Financial Conduct Authority (FCA) to stress-test all mortgage applications. This means checking whether you could still afford your repayments if interest rates rose significantly β€” typically by 3% above the initial rate. Even if you're on a fixed-rate deal, lenders must ensure you'd manage when that deal ends and you move to a variable rate. This is why you may be offered less than you expect, even with a healthy income.
