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.
However, the income multiple is just the starting point. Lenders also stress test your affordability by checking whether you could still afford payments if interest rates rose by 3% above the product rate. They will scrutinize your outgoings including childcare, existing debt payments, subscriptions, and living costs.
To maximise your borrowing: reduce or clear existing debts (credit cards, loans, car finance), minimise regular commitments in the months before applying, and ensure your credit file is clean. A larger deposit does not increase how much you can borrow, but it does give you access to better interest rates — the lowest rates are typically at 60% LTV (loan-to-value) or below.
Frequently Asked Questions
Does my partner's income count?
Yes, for joint applications. Most lenders combine both incomes and apply the 4-4.5x multiple to the total. This significantly increases borrowing capacity.
Do bonuses and overtime count?
Most lenders will include regular bonuses and overtime, but usually only at 50-75% of their value. Some lenders ignore them entirely. Having 2-3 years of consistent bonus history helps.
