Frequently Asked Questions
How much can I borrow for a UK mortgage?
Most UK lenders offer 4-4.5 times your annual salary, though some specialist lenders may go up to 5.5x. The exact amount depends on your income, credit score, deposit size, and monthly outgoings. Use the affordability calculator alongside this mortgage calculator to determine your borrowing capacity.
What deposit do I need for a UK mortgage?
The minimum deposit is typically 5-10% of the property value, but larger deposits (15-20%+) unlock better interest rates. First-time buyers can access government schemes like Help to Buy and Shared Ownership with deposits as low as 5%. A 20% deposit is the sweet spot for avoiding higher lending charges.
What is included in my monthly UK mortgage payment?
Your monthly payment includes the mortgage repayment (principal and interest). Additionally, budget for: Council Tax (£100-300/month), Buildings Insurance (£20-50/month), Life Insurance (optional but recommended), Ground Rent and Service Charges (for leasehold properties), and potentially mortgage protection insurance.
Should I choose a fixed or variable rate mortgage in the UK?
Fixed-rate mortgages offer payment certainty (most popular: 2, 3, or 5-year fixes). Variable rates (tracker, standard variable rate, or discount) can be lower initially but may rise with Bank of England base rate changes. In 2025, with rate uncertainty, many borrowers prefer fixed rates for budgeting security.
What are mortgage arrangement fees in the UK?
Arrangement fees (also called product fees) typically range from £0 to £2,000, with some deals charging a percentage of the loan amount. Lower-rate mortgages often have higher fees. You can either pay upfront or add the fee to your mortgage, though adding it increases your total interest paid over the term.
How does stamp duty affect my UK mortgage affordability?
Stamp duty is a one-off tax on property purchases. First-time buyers pay no stamp duty on properties up to £425,000 (£625,000 if buying in England or Northern Ireland). Rates then increase progressively. For example, on a £300,000 property, first-time buyers pay £0, while existing homeowners pay £2,500. Budget for this separately from your mortgage.
What is mortgage affordability in the UK and how is it calculated?
Lenders assess affordability by examining your income, regular outgoings (credit cards, loans, childcare), credit score, and performing stress tests at higher interest rates (typically 3% above current rates). They calculate your debt-to-income ratio and ensure you can afford payments if rates rise. Improving your credit score and reducing existing debts increases affordability.
Can I remortgage to get a better deal in the UK?
Yes! Remortgaging means switching to a new mortgage deal, either with your existing lender or a new one. Do this when your fixed-rate period ends to avoid expensive standard variable rates. Even switching to a rate 0.5% lower can save thousands. Consider remortgaging if your property value has increased (improving your loan-to-value ratio) or if your financial situation has improved.
