There can be several fees when remortgaging. Your advisor will explain any additional costs and help you decide the best option for your circumstances.
An example of remortgaging fees are
Early Repayment Charges
If you switch deals during the initial fixed or tracker period, then you will likely have to pay an early repayment charge (ERC). The ERC is calculated as a percentage of the outstanding debt.
Your annual mortgage statement will set out what ERC would be payable.
Arrangement fees
Mortgages come with a product or arrangement fees. These can be added to the mortgage balance, though remember that doing so means you will pay interest on it, so it could cost you more than paying it upfront.
Legal fees
Unless you are doing a product transfer, there may be legal fees to cover things like valuing the property and conveyancing.
These fees will be much lower than for someone who is moving to a new property as there is less legal work involved.
