Why Is There Such a Big Gap?

Every UK mortgage lender runs its own affordability model. The differences come down to three main factors:

Income Multiples

Most lenders cap borrowing at 4 to 4.5 times your annual salary. But since the 2025 PRA/FCA relaxation of the 4.5× lending cap, many now stretch to 5.5× (Halifax, Santander, Skipton BS, Virgin Money) or 6.0× (Nationwide, Barclays, NatWest, Leeds BS), with HSBC Premier reaching 6.5× and the market top hitting 7× on select gated products. That single variable alone can add tens of thousands to your maximum loan, subject to lender criteria, affordability and credit assessment.

Stress Testing

Lenders must check that you could still afford repayments if interest rates rose. They each use different stress rates, typically between 6% and 8.5%. A lower stress rate means the lender can offer you more.

Enhanced Multiples

Several lenders offer higher income multiples for first-time buyers, professionals (doctors, accountants, solicitors), or borrowers with larger deposits. These enhanced schemes can significantly boost the amount you are offered.

Frequently Asked Questions

How much can I borrow based on my salary?

Most lenders use income multiples of 4-4.5x your gross annual salary. Since the 2025 PRA/FCA relaxation of the 4.5x cap, many now go to 5.5x, with lenders like Nationwide, Barclays and NatWest reaching 6.0x and HSBC Premier 6.5x for eligible borrowers. Our calculator checks 60+ lenders to show you the full range, subject to lender criteria, affordability and credit assessment.

What income multiple do mortgage lenders use?

Standard income multiples range from 4x to 5.5x salary, and several lenders now reach 6.0x to 6.5x for eligible applicants following the 2025 relaxation of the 4.5x lending cap. The multiple depends on the lender, your deposit size, employment type, and whether you are fixing for 5+ years. Higher multiples are typically available with deposits of 10-15% or more, subject to lender criteria, affordability and credit assessment.

Does overtime and bonus count towards a mortgage?

Most lenders accept overtime, bonus, and commission income, but they calculate it differently. Some use 50% of the average, others use 100%. Our calculator accounts for each lender's specific policy.

How much can I borrow with a joint mortgage?

With a joint application, most lenders combine both incomes when calculating affordability. This typically increases your maximum borrowing significantly. Some lenders are more generous with joint applications than others.

Does my deposit size affect how much I can borrow?

Yes — a larger deposit can unlock higher income multiples. Many lenders increase their maximum from 4.5x to 5.5x salary (and some to 6.0x or more) at lower loan-to-values, because the reduced risk lets them lend further, subject to lender criteria, affordability and credit assessment.
