Be honest, have you looked at your mortgage statement lately and felt a little bit of a cold shiver? You aren't alone. If you’re one of the 1.8 million people across the UK coming off a low fixed rate this year, that "deal end date" probably looks like a ticking clock.
Maybe you’re sitting in your kitchen in Wigan or scrolling through your phone on the tram into Manchester, wondering how on earth the world changed so much since you last signed a mortgage deed. We get it. The headlines are a bit of a rollercoaster. Last week, the Bank of England held the base rate at 3.75%, which sounds like stable news, right? But then you see lenders nudging their prices up or down anyway.
Why? Because of swap rates (the price lenders pay to borrow the money they lend to you). It’s a bit like the wholesale price of petrol, even if the main taxes don't change, the price at the pump still moves.
Navigating this doesn't have to be a nightmare, though. It’s just about knowing where the tripwires are hidden. Here are the 7 biggest remortgage mistakes we’re seeing right now and, more importantly, how you can dodge them.
1. Playing the "Waiting Game" with the SVR
The biggest mistake? Doing nothing. If you let your current deal expire without a new one lined up, your lender will automatically move you onto their Standard Variable Rate (SVR).
The SVR Shock: This isn't just a small price hike. It’s a financial cliff edge. SVRs are often double (or more) the rate of a competitive fixed deal. For a typical mortgage in Manchester or Wigan, slipping onto the SVR for even a month or two could cost you hundreds of extra pounds. Money that could have gone on a holiday, a new sofa, or, let's be real, the ever-increasing grocery bill.
How to dodge it: You can usually secure a new rate 3 to 6 months before your current one ends. Think of it as "booking" your future rate. If rates drop before you switch, we can often jump to a better one. If they rise? You’re already protected.
2. Thinking Your Current Lender Is Your Best Friend
We all like a bit of loyalty, don't we? Your bank sends you a nice birthday email, maybe a coffee voucher. But when it comes to your mortgage, loyalty rarely pays in cash.
A lot of people just take the "product transfer" their current lender offers because it’s easy. It’s a few clicks in an app. Done. But is it the best deal on the market? Probably not. Your bank only shows you their products. They aren't going to tell you that the lender down the street has a rate that’s 0.5% lower.
How to dodge it: Speak to a mortgage broker in Manchester or Wigan (like us!) who has access to the whole market. We can compare your current lender’s "stay put" offer against everything else out there. If staying put is the best move, we’ll tell you. If it isn’t, we’ll save you the money.
3. Getting Distracted by the "Headline Rate"
It’s easy to get "rate envy." You see a flashy 3.9% deal online and think, "That’s the one!" But wait. Have you looked at the fees?
Some of the lowest interest rates come with massive arrangement fees, sometimes £999, sometimes £1,999, or even a percentage of the loan. If you have a smaller mortgage balance, paying a huge fee to get a slightly lower rate might actually cost you more over the two or five years of the deal.
The Math (The boring but important bit):
- Option A: 4.2% rate with £0 fee.
- Option B: 3.9% rate with a £1,999 fee.
In many cases, Option A actually leaves more money in your pocket at the end of the term.
How to dodge it: Always look at the "total cost over the term." We do these calculations for our clients every day to make sure the "cheap" deal isn't actually a hidden luxury.
4. Ignoring the Power of "Swap Rates"
You’ve probably heard us talking about the base rate, that’s the one the Bank of England sets. But lenders actually price their fixed-rate deals based on swap rates.
In May 2026, swap rates have been a bit jumpy. Even if the base rate stays at 3.75%, if the "market" thinks inflation is going to be sticky, swap rates go up, and mortgage deals get pulled and replaced with more expensive ones overnight.
How to dodge it: Don't wait for the next Bank of England meeting to make a move. If you see a deal you like, grab it. Markets move faster than the news cycle. Your local broker can keep an eye on these daily fluctuations so you don't have to.
5. Forgetting to Check Your Property Value
This is a classic. Your "Loan to Value" (LTV) is the secret sauce of mortgage pricing. The more equity you have in your home, the lower the interest rates usually get.
Many people assume their house is worth what they paid for it, or what a basic online estimator says. But if property prices in your part of Manchester have ticked up, you might find yourself in a lower LTV bracket (say, 60% instead of 75%). This unlocks a whole new level of cheaper deals.
How to dodge it: Before you remortgage, check recent sales on your street. If you’ve done a big renovation, new kitchen, extension, or even just some high-end landscaping, tell us! A higher valuation could save you thousands over the life of your mortgage.
6. Extending the Term Just to Lower the Monthly Payment
We get it. Life is expensive right now. When you see your new monthly payment is going up because rates are higher than they were in 2021, the temptation is to stretch the mortgage out from, say, 20 years to 30 years to keep the monthly cost down.
It feels like a win in the short term. Your bank balance looks healthier today. But you’re essentially paying interest on that debt for an extra decade. It can add tens of thousands of pounds to the total cost of your home.
How to dodge it: If you have to extend the term to make ends meet, make sure you have a plan to shorten it again later or make overpayments when things get easier. Use it as a safety net, not a permanent plan.
7. Skipping the "Agreement in Principle" (AIP)
You might think, "I already have a mortgage, I don't need an AIP." But things change. Lenders' criteria change. Your income might have changed (maybe you went self-employed or changed jobs).
Starting a remortgage without knowing for sure that you're still "eligible" in the eyes of a new lender is a recipe for stress. There's nothing worse than finding a perfect rate, only to be turned down because of a minor technicality in your paperwork.
How to dodge it: Treat your remortgage like a new purchase. Get your documents in order: payslips, bank statements, the lot. We can help you get an AIP sorted early so you can shop with confidence. (Check out our helpful guides for more on getting "mortgage ready").
