How Much Can I Borrow for a Mortgage in the UK?

Most UK mortgage lenders calculate how much you can borrow based on a multiple of your annual income — typically between 4× and 4.5× your salary (or combined salary if buying with a partner). Some lenders will go up to 5× income for higher earners or professionals.

Your deposit size also determines your Loan to Value (LTV) ratio. A lower LTV (larger deposit) typically means better interest rates. Most lenders require a minimum 5–10% deposit, and the best rates are usually available at 60–75% LTV.

Frequently Asked Questions

How much can I borrow for a mortgage?
Most lenders offer 4–4.5× your annual income. With a combined income of £80,000, you could typically borrow £320,000–£360,000 at standard multipliers, subject to credit and affordability checks.
What is LTV and why does it matter?
LTV (Loan to Value) is the ratio of your mortgage to the property's value. A 90% LTV means you have a 10% deposit. The lower the LTV, the better the interest rates you will be offered — 60–75% LTV usually gets the best deals.
Do I need a 10% deposit?
You can get a mortgage with a 5% deposit, but you will pay higher interest rates and have fewer lenders to choose from. A 10% deposit significantly opens up your options. A 25% or more deposit typically gets the most competitive rates.
How do outgoings affect what I can borrow?
Lenders carry out affordability assessments looking at your monthly outgoings including credit cards, loans and car finance. Higher outgoings reduce the amount you can borrow, even if your income-based calculation is high.
