Remortgaging means switching your current mortgage to a new deal, either with the same lender or a different one.
For this timing matters.
You should review your mortgage when your deal is ending, your finances have changed, property values have moved, you want to release equity, or your current deal no longer fits your needs. Starting the process at least six months early gives you the best chance of a smooth switch.
Your mortgage is almost certainly your biggest monthly outgoing.
Yet many homeowners set up their deal and then forget about it for years. That’s understandable. Life gets busy, and as long as the monthly payment leaves your account on time, it’s easy to assume everything is ticking along fine.
The problem is that mortgages don’t age well. The deal you arranged two, three or five years ago may have been perfect at the time, but your circumstances, the property market and the wider economy have all moved on since then.
If you haven’t reviewed your mortgage recently, there’s a fair chance you’re paying more than you need to. According to UK Finance, around 1.8 million fixed-rate mortgage deals are due to end in 2026, and many of those borrowers could save money by acting before their deal expires.
Remortgaging is simply the process of switching to a new mortgage deal. You can do this with your current lender (known as a product transfer) or move to a different lender entirely.
The aim is usually to save money, but that’s not the only reason to consider it. This guide covers five clear triggers that should prompt you to pick up the phone and talk to a mortgage broker.
What Happens When Your Fixed-Rate Deal Ends?
This is the most common reason homeowners remortgage, and it’s the one that catches people out the most. If you’re on a fixed-rate mortgage, your initial deal will have a set end date. Once that date passes, your lender will move you onto their standard variable rate, or SVR.
Why the SVR Costs You More
The SVR is your lender’s default rate, and it’s almost always higher than the deal you were on. As of early 2026, the average SVR across UK lenders sits at around 7.25%, according to Moneyfacts.
That’s well above the best fixed rates available.
For someone with a £500,000 mortgage, moving from a competitive fixed rate to an SVR could add hundreds of pounds to your monthly payment. Over a full year, that adds up quickly.
Lenders will write to you before your deal ends, but the notice period can be short and it’s easy not to prioritise it. If you wait for that letter before taking action, you may not have enough time to arrange a smooth switch.
When to Start Looking
The best advice is to begin your mortgage review at least six months before your current deal expires. This gives you time to compare options, submit an application and have everything in place so you move straight from one deal to the next without ever touching the SVR.
Most mortgage offers are valid for between three and six months, so you can lock in a new deal well ahead of your current one ending. If rates drop before your new deal starts, a broker can often switch you to the cheaper option.
Should You Remortgage When Your Finances Change?
Life doesn’t stay the same, and neither should your mortgage. A change in your income, your spending patterns or your financial goals could mean your current mortgage no longer fits.
Earning More Than Before
If your income has increased since you took out your mortgage, you may now qualify for deals that weren’t available to you previously.
Higher earners often have access to lower rates, and you might also want to consider overpaying your mortgage to reduce the balance faster. Not all mortgages allow overpayments without penalty, so switching to one that does could save you thousands over the term.
Tighter Finances
On the other hand, if your income has dropped or your outgoings have increased, you might need a mortgage that offers more flexibility. Some deals allow payment holidays or let you extend the term to reduce your monthly payments.
A broker can look at what’s available and find something that works with your current budget rather than against it.
The FCA confirmed changes to mortgage affordability rules in December 2025, making it easier for some borrowers to remortgage with a new lender rather than being stuck with their current provider.
Changes in Employment
Moving from employment to self-employment, or vice versa, can also be a trigger. Lenders assess self-employed borrowers differently, and some are more accommodating than others. If you’ve been self-employed for two or more years and have solid accounts, you may find better options are now open to you.
How Do Property Values Affect Your Remortgage Options?
The value of your home plays a direct role in the mortgage deals available to you.
Lenders price their products based on something called the loan-to-value ratio, or LTV. This is the size of your mortgage expressed as a percentage of your property’s current market value.
How a Lower LTV Helps You
If your property has increased in value since you took out your mortgage, your LTV will have dropped. A lower LTV generally means access to better rates. For example, someone who originally borrowed at 85% LTV might now sit at 70% LTV because their home is worth more. That shift could open up noticeably cheaper deals.
You can get a rough idea of your property’s current value by checking recent sale prices for similar homes in your area. Websites like Zoopla and Rightmove both offer free estimates, though these are only a guide. Your lender will arrange a formal valuation as part of any remortgage application.
What If Property Values Have Fallen?
A drop in property values can push your LTV in the wrong direction.
If your home is now worth less than when you bought it, your LTV will be higher and your options may be more limited. In some cases, you could even find yourself in negative equity, where you owe more than the property is worth.
If you’re in this position, speak to a broker before making any decisions. There are lenders who specialise in higher LTV cases, and a product transfer with your current lender may still be possible even if a full remortgage isn’t.
Can You Remortgage to Release Equity?
Over time, as you pay down your mortgage and your property value rises, you build up equity in your home.
Equity is the difference between what your property is worth and what you still owe on it. Remortgaging can allow you to access some of that equity by borrowing more than your current outstanding balance.
Common Reasons to Release Equity
Homeowners release equity for all sorts of reasons. Home improvements are one of the most popular, especially projects that add value to the property such as extensions, loft conversions or kitchen renovations. If you’re borrowing to improve the property, the value you add often outweighs the cost of the additional borrowing.
Other common reasons include consolidating higher-interest debts, helping a family member with a deposit, or funding a significant purchase. Some property investors also remortgage to release equity for a deposit on a buy-to-let property.
Points to Consider
Releasing equity means increasing the size of your mortgage, so your monthly payments will rise unless you also extend the term. You should think carefully about the full cost of borrowing over the remaining life of the loan, not just the monthly payment.
If you consolidate unsecured debts into your mortgage, you’re turning short-term debt into long-term debt secured against your home. While the monthly payments may be lower, the total amount you repay could be higher.
MoneyHelper, the government-backed guidance service, recommends thinking carefully before securing other debts against your home. Your home may be repossessed if you do not keep up repayments on your mortgage.
A broker can run the numbers for you so you can see the full picture before committing.
What If Your Current Mortgage No Longer Suits You?
Sometimes the trigger isn’t a dramatic life event or a market shift. It’s simply that your priorities have changed and your mortgage hasn’t kept pace.
Switching Mortgage Type
You might want to move from an interest-only mortgage to a repayment deal, or the other way around. Interest-only mortgages mean lower monthly payments, but you’ll need a plan to repay the capital at the end of the term.
Repayment mortgages cost more each month but steadily reduce the balance.
Some homeowners switch from a variable rate to a fixed rate because they want the certainty of knowing exactly what they’ll pay each month. Others move in the opposite direction if they believe variable rates will stay lower than fixed alternatives.
Adjusting the Term
You might also want to shorten or lengthen your mortgage term.
Shortening the term means higher monthly payments but less interest paid overall. Lengthening it reduces your monthly outgoing but increases the total cost of the loan. Either way, remortgaging gives you the chance to reset the term to match where you are now rather than where you were when you first bought the property.
Adding or Removing a Borrower
Life changes like marriage, divorce or the death of a partner can mean you need to add or remove someone from the mortgage. This usually requires a remortgage, as the lender will need to reassess the application based on the new circumstances.
When Should You Start the Remortgage Process?
Getting the timing right makes a real difference. As a general rule, you should start looking at your options around six months before your current deal ends.
This gives you enough time to compare deals, gather your paperwork and submit an application without feeling rushed.
If you’re already on your lender’s SVR, there’s no need to wait. Every month you stay on the SVR is a month you’re likely overpaying. Speak to a broker as soon as you can.
For those thinking about releasing equity or switching mortgage type, there’s no fixed timeline. The key is to get professional advice before making any decisions, so you understand the costs, the options and whether remortgaging is genuinely the right move for your situation.
Why Use a Mortgage Broker to Remortgage?
You can remortgage directly with a lender, but working with a whole-of-market mortgage broker gives you access to deals from across the entire market.
Around a third of lenders only work through brokers, so going direct means you could be missing products that aren’t available to you otherwise.
A good broker will assess your situation, compare products from dozens of lenders and recommend the deal that best fits your needs. MoneyHelper recommends speaking to a few different firms to compare what’s on offer and to check fees before committing.
They handle much of the paperwork and keep the process moving, which takes a lot of the hassle out of remortgaging.
At Respect Mortgages, we can introduce you to an experienced, independent mortgage broker who will search the whole market on your behalf. There’s no obligation, and the initial conversation is free. If any of the five triggers in this guide apply to you, it’s worth having that conversation sooner rather than later.
Frequently Asked Questions
You should review your mortgage at least once a year, and always six months before your current deal ends. Annual reviews help you keep track of your LTV, spot better deals and check your mortgage still matches your circumstances. Setting a diary reminder is a simple way to stay on top of it.
Yes, but you’ll probably have to pay an early repayment charge (ERC). This is usually a percentage of the outstanding balance and can run into thousands of pounds. You’d need to weigh the ERC against the savings from switching. A broker can calculate whether it makes financial sense in your case.
A product transfer is when you switch to a new deal with your current lender without a full remortgage application. It’s usually quicker and involves less paperwork, but you’re limited to what your current lender offers. Remortgaging with a new lender opens up the whole market, which often means better rates.
If you’re switching to a new lender, yes. A solicitor or conveyancer handles the legal work involved in transferring the mortgage from one lender to another. Many lenders offer free legal work as part of their remortgage package, so this doesn’t always mean an extra cost. Product transfers with your existing lender usually don’t require legal work.
Yes, remortgaging to consolidate debts is common. You borrow more than your outstanding mortgage balance and use the extra funds to pay off other debts like credit cards or personal loans. Be aware that you’re securing previously unsecured debt against your home, and extending the repayment period can mean paying more in total interest.
A whole-of-market mortgage broker can compare deals from dozens of lenders, including some that only work through intermediaries. Going direct limits you to one lender’s products. Brokers also handle paperwork and can advise on the best approach for your situation. For most people, using a broker saves time and often money too.
