Remortgaging can look simple when you compare interest rates, but the rate is only one part of the price. A deal with a slightly lower rate can become more expensive once product fees, legal work, valuation costs and charges from your existing lender are included. The clearest way to understand remortgage fees is to separate them by who charges them and when they become payable.
Fees charged by your existing lender
Early repayment charge
An early repayment charge, or ERC, can apply if you repay or switch your mortgage before a fixed, discounted or other deal period ends. The FCA explains that an ERC is often linked to the outstanding balance and may reduce as the end of the deal approaches. Your mortgage offer sets the actual rules, so check the redemption statement or ask your lender for a current figure before switching.
This is one of the remortgage charges most likely to change whether switching early makes financial sense. A lower new rate may look attractive, but a large ERC can absorb much of the expected saving.
Mortgage exit or account closure fee
An exit fee is an administration charge for closing the mortgage account, not an ERC for leaving a deal early. It may also be described as a redemption or discharge fee. Some products have no exit charge, so check your mortgage documents.
Fees charged by the new lender
Lender arrangement fee or product fee
The lender arrangement fee is often the most visible cost on a new mortgage. It may also be called a product, completion or application fee. MoneyHelper’s current mortgage-cost guidance says arrangement or product fees can be around £1,000 to £2,000 or more, although fee-free products are available.
You may be able to pay the fee upfront or add it to the mortgage. Adding it reduces the cash needed immediately, but it increases the balance on which interest is charged. Check when the fee becomes payable and whether it is refundable if the remortgage does not complete.
Booking or application fee
Some lenders charge a smaller fee when you reserve a product or submit an application. MoneyHelper gives a general booking-fee range of about £100 to £200. These charges are not universal, and refund rules vary, so look beyond the headline product fee when comparing mortgage fees UK lenders may apply.
Valuation fee
A new lender needs to confirm that the property provides adequate security for the loan. It may use an automated valuation, desktop assessment or physical inspection. Many remortgage products include a standard valuation, while others charge for it. MoneyHelper says borrower-paid mortgage valuations can vary with property value and may be roughly £150 to £800.
Legal and conveyancing costs
When you move to a different lender, legal work is normally needed to redeem the old mortgage and register the new lender’s charge. Some deals include a basic legal package or cashback toward legal costs; others require you to pay a solicitor or conveyancer.
“Free legals” does not always mean every legal expense is covered. Extra work can create additional charges, particularly where there is a transfer of ownership, a leasehold issue or another matter outside the lender’s standard package. Ask what is included before treating the legal cost as zero.
Broker and adviser fees
If you use a mortgage broker, check how the service is paid for. Some brokers charge the borrower a fixed fee, percentage or staged fee; others receive payment from the lender without charging the customer directly. Any borrower-paid broker fee belongs in the same overall comparison as the lender’s charges.
How to compare a low rate with a higher-fee deal
Consider a simplified example. Suppose you have a £180,000 mortgage and are comparing two deals. One has a rate 0.15 percentage points lower but carries a £1,499 product fee; the other has no product fee. On an unchanged £180,000 balance, that rate difference represents about £270 of interest in the first year. On that rough basis, it would take more than five years for the interest difference alone to equal the fee.
Real mortgage balances reduce, monthly payments vary and the rates may apply for different periods, so this is only an illustration. It shows why the lowest rate is not automatically the cheapest deal, especially over a two- or five-year product period.
Compare the total cost over the period you expect to keep the deal. Include the product fee, valuation, legal costs, broker fee, any ERC or exit fee, and expected interest. If you add a fee to the loan, include the interest charged on that fee as well.
Ways to reduce avoidable remortgage costs
Ask your current lender for a redemption figure and the date on which any ERC reduces or ends. Then compare external remortgage offers with product-transfer options from your existing lender. A product transfer may involve fewer administrative steps and can avoid some valuation or legal costs, although the rate still needs to be competitive.
Check each new deal for incentives such as free standard valuation, included legal work or cashback. Treat incentives as part of the calculation rather than as a reason to choose a deal on their own. Also confirm which charges are refundable before paying anything upfront.
Frequently asked questions
How much do remortgage fees usually cost?
There is no single standard total. A remortgage can involve a product fee, valuation, legal costs, broker charges and fees from the existing lender. Some new deals include free valuation or basic legal work, while an ERC can be the largest single cost.
Can I add remortgage fees to the mortgage?
Some lenders allow certain product fees to be added to the loan. This reduces the upfront cash needed but increases the mortgage balance, so interest is charged on the fee.
Do I always need to pay legal fees when remortgaging?
Legal work is generally required when switching lender, but you may not receive a separate bill if the new deal includes a standard legal package. Additional or non-standard work can still cost extra. A simple product transfer with your existing lender may not require the same conveyancing process.
Is a fee-free remortgage always cheaper?
No. A fee-free deal may have a higher interest rate, while a fee-paying deal can sometimes cost less overall. Compare the total cost over the period you expect to keep the mortgage rather than judging the deal by either the rate or fee alone.
Putting the fees into one decision
Remortgage fees become easier to compare when you group them into three buckets: charges for leaving the old mortgage, charges for taking the new one, and third-party costs needed to complete the switch. Add those costs to the expected interest over the relevant deal period, then compare like with like. Before committing, get current figures from your existing lender and the proposed new lender because fee names, incentives and refund rules vary from product to product.
