Mortgage rates in London are generally based on the same lender criteria as elsewhere in the UK, including your loan-to-value (LTV), income, credit history, mortgage type and the lender’s fees. Compare the overall cost, not just the headline rate, as a lower rate with a large arrangement fee may not be cheapest for your circumstances. Your options can also change as market conditions and the Bank of England’s base rate change. An FCA-authorised mortgage broker may help you compare suitable deals, or you can check offers directly with lenders.
