Mortgage Affordability in UK: A Detailed Analysis for 2026

UK homebuyers are currently spending an average of 21.2% of their gross income on mortgage payments, the highest level since 2008. However, in certain areas, affordability is even tighter, with North Norfolk and the London Borough of Hillingdon leading the pack at 25.7% and 25.1% respectively.

Understanding the Numbers

Scenario 1: First-Time Buyer

Consider a first-time buyer in North Norfolk, planning to buy a property worth £250,000 at 90% LTV. With the current base rate of 3.75%, their monthly payment would be approximately £1,158. If they were earning the UK median gross monthly income of £2,208, this would mean they are spending 52.4% of their income on mortgage repayments. This is significantly higher than the national average of 21.2% and illustrates the affordability challenge for first-time buyers in high-cost areas.

Scenario 2: Remortgager

Now, let’s consider a remortgager in the London Borough of Hillingdon, with a £300,000 mortgage at 80% LTV. Their monthly payment would be approximately £1,390. If they were earning the London median gross monthly income of £2,639, this would mean they are spending 52.7% of their income on mortgage repayments. This scenario highlights the impact of the current base rate on remortgagers, particularly in areas with high property values.

Scenario 3: Landlord on Interest-Only

Finally, let’s look at a landlord with a £200,000 interest-only BTL mortgage. Their monthly cost would be approximately £625. This demonstrates that, despite the high base rate, landlords with interest-only mortgages may still find their payments manageable, particularly if they have a good rental yield.

Market Context

Compared to a year ago, when the base rate was 3.25%, the current rate of 3.75% has significantly impacted mortgage affordability. This increase in the Bank of England base rate has led to higher mortgage payments for homeowners, particularly in areas like North Norfolk and Hillingdon. It’s important to note that these figures are averages and individual circumstances will vary. However, they provide a useful snapshot of the current state of mortgage affordability in the UK.

Regional Differences

While the national average for mortgage affordability sits at 21.2%, there are stark regional differences. For instance, homeowners in South Hams, Devon, spend just 5% of their income on mortgage payments, while those in Cambridge, East Anglia, and the Derbyshire Dales spend slightly more at 5.3%. These figures highlight the disparity in mortgage affordability across different regions in the UK.
