Remortgage Pitfalls: What to Watch Out For

Remortgaging seems simple: swap out your old mortgage for a better one and save some money, right? Well, it can actually trip you up if you’re not careful. People often miss the hidden fees or rush the process because they’re excited about lower rates. Then—bam—you’re hit with costs you didn’t see coming or stuck with a deal that eats away your savings.

If you’ve started looking at new mortgage offers, it helps to spot the potholes before you fall in. Not every ‘low rate’ is as great as it sounds. Sometimes, lenders roll extra charges into the deal or set weird conditions that catch you out down the line. Spotting these up front can make a world of difference for your wallet—and your stress levels.

Unexpected Costs and Fees

People get tripped up by hidden costs when they remortgage. Those shiny new deals can come packed with extras that aren’t obvious until you’re deep into the paperwork. One of the big ones is the arrangement fee—sometimes called a product fee—which can be anywhere from £500 to over £2,000. Lenders love to advertise low interest rates, but they often sneak in charges like this to make up the difference.

Another fee that catches folks is the early repayment charge (ERC) on your old mortgage. If you’re still within your initial fixed or tracker period, this charge can take a solid chunk out of your savings—think 1% to 5% of your outstanding balance. That can easily swallow any benefit from your lower new rate. There are also exit fees or admin charges—say £50 to £295—just for leaving your old lender.

Don’t forget about legal fees and property valuation fees. While some lenders offer to cover these as an incentive, it’s not always the case. If they don’t, you’re possibly looking at several hundred pounds extra. Not accounting for these costs upfront can seriously dent the savings you expect from a remortgage.

• Always get a full breakdown of fees from your new lender before you commit.
• Check the terms of your current mortgage for early repayment penalties and exit fees.
• Add everything up—sometimes, after all the costs, sticking with your old deal works out cheaper.

That’s why it pays to look past the headline rate and figure out the actual cost of moving—because those remortgage mistakes can get expensive fast.

Credit Score Surprises

One of the sneakiest headaches with remortgaging is how your credit score can get in the way—or take a sudden hit. Lenders check your credit with a fine-tooth comb when deciding whether to give you a new deal. A lot of people think their score only matters when buying their first house, but honestly, it matters just as much (sometimes more!) if you’re trying to snag a good remortgage rate.

Here’s the catch: every time you apply for a new mortgage, the lender does a “hard search.” Too many of these, especially in a short space of time, and your credit score can take a knock. According to Experian, even a single hard search might drop your score by a few points. String several together, and suddenly you’re seen as a higher risk—making the attractive rates evaporate.

The little things can trip you up too. Late payments on any current debt, recent credit card borrowing, or even opening a new car loan just before you apply can spook lenders. Some banks have thresholds—if your score slips by as little as 20 points, you might lose access to the best rates. That’s money out of your pocket every single month.

Here’s a table with some typical impacts of credit changes when you remortgage:

So, what actually helps? Check your credit report before you do anything else. Fix any little errors—like a misspelled name or old address—because lenders notice. If you know you’ll remortgage later in the year, avoid applying for new credit or missing any payments. If you’re ever unsure, talking to a broker can save loads of hassle. They see this stuff all the time and know which lenders are pickier than others.

Impact on Long-Term Finances

When you remortgage, it’s easy to get drawn in by the headline rates and the quick monthly savings. But the catch with remortgaging is that short-term wins can sometimes backfire over the years. Before you jump, check how switching affects the big picture—not just the next few payments.

One big mistake is stretching out your loan term. Let’s say you’ve paid off eight years on a 25-year mortgage but get a new deal over another 25 years. Yes, your monthly payments will drop, but you could end up paying more interest over time than if you’d stuck with your old plan. Lenders don’t always spell that out. That’s why it pays to do the math—before you sign anything.

Sticker shock, right? You might save £210 a month, but pay an extra £27,000 in interest over the long run. That’s a hefty price tag for smaller bills now.

There’s also the trap of fixed-rate periods ending at the wrong time. If you remortgage on a low-rate fixed deal and forget to remortgage again before that ends, you could land on your lender’s standard variable rate, which is usually much higher. This can wipe out any savings from your earlier remortgage.

Here are some ways to protect your finances when remortgaging:

• Remortgage for the amount of time left on your old mortgage, not a brand new term, unless you really need lower monthly payments and know the trade-offs.
• Set reminders for when your fixed period ends so you don’t sleepwalk onto a higher rate later.
• Use free online calculators to project your total interest over different terms—don’t just trust the monthly figures.

Whatever you do, keep your eye on the long game. The real cost of remortgaging is sometimes hidden in the fine print and the years you’ll be making payments. Making smart choices now can save a fortune later.

Getting Stuck with Bad Deals

Here’s where things can get messy. Plenty of folks fall for shiny deals that look like an easy win, but there’s always a catch or two buried in the fine print. Let’s be real: lenders are out to make money, so their best offer for you might not be all it’s cracked up to be.

The classic trap? Introductory rates that skyrocket after the honeymoon period. You snag a “too good to be true” rate for the first one or two years, and then—suddenly—you’re paying much more. Switch again, and you’re paying new fees. Or you stick it out and your budget takes a hit.

And don’t forget about limiting terms. Some deals tie you in with strict early repayment charges. If you want out before the end of the fixed term, you could be looking at a chunk of money down the drain. According to a 2024 UK housing study, nearly 23% of remortgagers said they underestimated the real cost of breaking out early.

• Remortgage offers with cashback: That money looks handy, but these deals usually have higher rates or lock-in periods. You end up paying more than you get.
• Configurable deals: Some variable mortgages sound flexible, but when the Bank of England rate moves, so does your payment. Brace yourself for surprises if you’re on a tight budget.
• Extra insurance: Lenders might tie in life or critical illness insurance with your new mortgage. It can be handy, sure, but being forced to buy their cover often means higher premiums than shopping around.

Tip: Always read every page of your mortgage offer—even the dull bits full of technical stuff. If the lender is dodging questions or pressuring you to sign fast, slow down and consider getting advice. The best deal is the one that actually works for your family, not just the fanciest headline.
