Will remortgaging save me money?
Remortgaging can save you money if you secure a lower interest rate or better terms, but it’s important to consider any fees. Early repayment charges on your current mortgage, arrangement fees, valuation costs, or legal fees can affect whether a remortgage is worthwhile overall.
When is the best time to remortgage?
The most common time to remortgage is when your current fixed or discounted deal is coming to an end, to avoid moving onto your lender’s higher standard variable rate. You may also consider remortgaging earlier, but you should check for early repayment charges before doing so.
Does using a remortgage calculator affect my credit score?
No. A remortgage calculator does not perform a credit check, so it won’t affect your credit score. A full mortgage application, however, will likely involve a credit search by the lender.
