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

Most UK lenders will offer between 4 and 4.5 times your annual gross income. Some specialist lenders go up to 5-5.5x for high earners or specific professions. For joint applications, both incomes are combined.

The income multiple is only the starting point. The figure most people miss is the stress test: lenders check whether you could still afford your monthly payments if the interest rate rose by 3% above the product rate. That test frequently cuts your actual offer below the headline multiple, especially if you carry existing debt or high fixed outgoings.

Lenders scrutinise your outgoings. Childcare costs, credit card balances, car finance, loan repayments, and regular subscriptions all reduce what they will lend you. Clearing or reducing those before you apply makes a direct difference.

A larger deposit will not increase how much you can borrow. A bigger deposit gives you access to better interest rates, and the lowest rates are typically reserved for borrowing at 60% LTV (loan-to-value) or below, but the amount a lender offers is driven by your income and outgoings, not the size of your deposit.

In the months before you apply, pay down revolving credit and avoid taking on any new credit agreements. A clean credit file and lower committed outgoings will do more for your borrowing limit than almost anything else.
