When you remortgage, the process of switching your existing mortgage to a new deal, either with your current lender or a different one, you’re not just changing your interest rate—you’re stepping into a web of costs most people overlook. These are the remortgage fees, the charges tied to switching your home loan, including arrangement fees, valuation costs, and legal expenses. They can easily add £1,000 to £3,000 to your bill, even if your new rate looks tempting. And no, your lender won’t always tell you upfront.
Many think remortgaging is just about getting a lower rate, but the real question is: does the savings outweigh the fees? You might save £200 a month on interest, but if your fees are £2,500, it’ll take over a year just to break even. That’s why understanding equity release, the process of accessing cash tied up in your home’s value through a new mortgage is critical. If you’re pulling cash out, you’re increasing your loan amount—and that changes everything. Lenders charge more for higher loan-to-value deals, and some fees scale with the amount you borrow. Then there’s the mortgage switching, the full process of moving from one lender to another, including legal work, surveys, and administrative steps. It’s not a quick paperwork shuffle. It takes 6 to 12 weeks, and delays can cost you if your old deal is ending soon.
Some people try to cut corners by skipping a valuation or using the same solicitor as their old lender. Bad idea. A cheap valuation might miss structural issues that could tank your deal later. And using the same solicitor doesn’t mean lower fees—it just means less competition. You’re better off comparing quotes. Also, watch out for lenders who advertise "no fees." They usually bake those costs into the interest rate, locking you in longer than you planned. The best deals often come with upfront fees, but if you plan to stay put for five years, those fees pay for themselves.
What you’ll find below are real examples of people who saved money—and others who paid way too much. You’ll see how much different lenders charge, what fees are negotiable, and when it’s smarter to stay put. No fluff. Just what you need to know before you sign anything.
Remortgaging can save money-but only if you avoid hidden fees, early repayment charges, and extended loan terms. Learn the real risks of switching mortgages in 2025 and how to protect your finances.
