UK Mortgage tip: Most lenders offer a maximum LTV (Loan-to-Value) of 95% (5% deposit). The best rates are typically available at 60% LTV or below. In 2026, 5-year fixed rates average around 4–4.5% in the UK.
FAQs
Monthly payment = Loan × (r/(1−(1+r)&sup{-n})) where r = monthly rate (annual rate/12) and n = total months. Example: £300,000 at 4.5% over 25 years → £1,640/month.
LTV (Loan-to-Value) is the loan amount as a percentage of the property value. Lower LTV = less risk for the lender = better interest rates for you. At 60% LTV you'll get the best rates; at 90%+ rates are significantly higher.
Fixed mortgages give certainty — your payment won't change for the fixed term (2, 3 or 5 years typically). Variable/tracker rates follow the Bank of England base rate. If rates fall, you pay less; if they rise, you pay more. In 2026, many borrowers prefer 5-year fixes for stability.
