Remortgaging can reduce your monthly payments, but the bigger impact is often on your overall costs.
Many homeowners look to remortgage to lower their monthly payments. While that can help in the short term, the bigger opportunity often lies in reducing your overall costs.
Your total mortgage cost is shaped by more than just your monthly figure. Interest rates, term length, and how your mortgage is structured all play a role. Remortgaging, when used correctly, gives you the opportunity to take control of that.
Key things to know before you remortgage
Before you compare deals, it helps to understand what actually affects your total mortgage cost.
Your rate is only part of the cost
A lower rate can reduce what you pay, but your term and how your mortgage is structured also shape your total cost.
Timing can save or cost you thousands
Review your options before your current deal ends to avoid higher rates and unnecessary interest.
Extending your term can increase the total cost
Reducing your monthly payments often means extending your term, which can increase the total interest you pay.
Fees can outweigh the savings
Arrangement fees, legal costs, and early repayment charges can offset any potential savings if not considered upfront.
Why total mortgage cost matters more than monthly payments
It’s easy to focus on what leaves your account each month. However, your mortgage is a long-term commitment, and most of the cost comes from interest over time.
Two mortgages can have similar monthly payments but very different total costs. A longer term may reduce your monthly outgoings, but it can significantly increase the amount of interest you pay overall.
Understanding this difference is key. Once you shift your focus from monthly affordability to total cost, your decisions become more strategic.
How remortgaging can reduce your total cost
Remortgaging can reduce the total amount you repay by adjusting your rate, term, or structure. Small changes can make a meaningful difference over time. Here’s what that can look like in practice:
Example: how remortgaging can reduce your total cost
Current mortgage:
- £200,000 over 25 years at 5%
- Monthly payment: ~£1,170
- Total repayment: ~£350,000
After remortgaging:
- £200,000 over 22 years at 4.5%
- Monthly payment: ~£1,230
- Total repayment: ~£325,000
What this means:
Your monthly payment increases slightly, but you could reduce your total repayment by around £25,000 over time.
This is where remortgaging can have the greatest impact, especially when you consider the balance between monthly payments and total cost over time.
Securing a lower interest rate
A lower rate means less interest charged over the life of your mortgage. Even a small reduction can make a meaningful difference when applied over many years.
If your current deal is no longer competitive, switching to a lower rate can immediately reduce your long-term cost.
Reducing your mortgage term
Shortening your term slightly increases your monthly payments but reduces the number of years you pay interest.
As a result, you can clear your mortgage sooner and reduce the total amount paid significantly.
Moving away from your lender’s standard variable rate
When a fixed deal ends, many mortgages move onto a standard variable rate. These rates are often higher and can change at any time.
Remortgaging before this happens can help you avoid unnecessary interest and maintain control over your costs.
Improving your loan-to-value
If your property value has increased, or you have paid down your mortgage, your loan-to-value may improve.
This can unlock better rates, which in turn reduces your total interest over time.
If your loan-to-value has improved, you may be able to access more competitive rates. Many remortgages now sit around 60% to 75% loan-to-value, where lenders typically offer their strongest pricing. Moving into this range can make a noticeable difference to your overall cost.

When remortgaging actually saves you money
If your current deal is ending, this is often the ideal moment to review your options. Acting early helps you avoid moving onto a higher rate and gives you more control over your next deal.
Timing plays an important role here. A full remortgage typically takes around 4 to 8 weeks to complete, so reviewing your options before your current deal ends can help you avoid moving onto a higher rate unnecessarily.
Your personal situation also matters. If your loan-to-value has improved, or your income has changed, you may now qualify for better products than before.
In the right circumstances, remortgaging becomes more than a switch. It becomes a way to reshape your mortgage in your favour.
When it might not reduce your total cost
While remortgaging can be effective, it is not always the right move.
If you leave your current deal early, you may face an early repayment charge. Depending on your balance, this can offset any potential savings.
Fees are another consideration. Arrangement fees, valuation costs, and legal work all contribute to the overall cost of switching.
Product fees are another factor to consider. These can range from £0 to £999 and are often added to the loan rather than paid upfront. While this can make switching easier, it also increases the total amount you repay over time.
In addition, extending your term to lower your monthly payment can increase the total interest you pay. This is one of the most common ways borrowers unintentionally increase their overall cost.
Is remortgaging worth it for you?
Remortgaging can reduce your total cost, but only if the numbers work in your favour.
If you can secure a lower rate, avoid unnecessary fees, and structure your mortgage effectively, the benefits can be significant.
If not, staying with your current lender or adjusting your existing deal may be the better option.
How to compare your options properly
When reviewing remortgage deals, it is important to look beyond the headline monthly payment.
Instead, focus on the full cost of the mortgage. A lower monthly figure may seem appealing, but it does not always lead to a better overall outcome.
Consider how much interest you will pay over the term, how long the mortgage will run, and what fees are involved. Bringing these elements together gives you a clearer view of the true cost.
It is also worth factoring in how quickly different options can be arranged. Switching to a new lender can take several weeks, while a product transfer with your existing lender may be completed in as little as one week. This can influence both your timing and your costs.
Once you compare mortgages this way, it becomes much easier to identify which option genuinely reduces your overall payments.
If you are considering remortgaging, start by reviewing your current deal, remaining term, and loan-to-value ratio. From there, you can compare what is available and decide whether switching makes sense for your situation.

What to consider before remortgaging
Before making a decision, it is worth taking a step back and looking at your wider plans.
If you expect your income to change or are planning to move in the near future, this may influence which type of deal suits you best.
You should also consider how comfortable you are with risk. Fixed rates offer stability, while variable options can change over time.
Remortgaging works best when it aligns with both your financial position and your longer-term goals.
Bringing it all together
Remortgaging can be an effective way to reduce your total mortgage cost, but the outcome depends on how your mortgage is structured.
It is not just about securing a lower rate. The term you choose, the fees involved, and the timing of your switch all shape what you pay overall.
When you bring these elements together, it becomes easier to see whether remortgaging is the right move and how to approach it with confidence.
