Remortgaging your home could save you hundreds or even thousands of pounds over time, but switching mortgage deals is not always free. From lender arrangement fees to legal charges and early repayment penalties, several expenses can affect whether changing your mortgage is worthwhile.
So, how much does it cost to remortgage in the UK? Some homeowners can switch with little or no upfront expense, while others may pay £1,000–£2,000 or more in arrangement fees alone. If you leave your existing mortgage deal early, the total cost could be considerably higher.
In this Saving Guide Hub guide, we explain the main remortgage fees in 2026, provide practical cost examples and show you how to compare mortgage deals without overlooking hidden expenses.
The cost to remortgage in the UK depends on your existing mortgage, the lender you choose, the size of your loan and whether you switch before your current deal ends. A straightforward remortgage may involve only a mortgage arrangement fee, particularly if the new lender includes free valuation and legal services.
However, homeowners who need additional legal work, use a fee-charging mortgage broker or face early repayment penalties could pay significantly more. This is why the overall cost of switching matters more than the advertised mortgage interest rate.
According to MoneySavingExpert’s remortgage fees guide, arrangement fees on mortgage deals can be around £1,000 and sometimes considerably higher. Some lenders offer fee-free mortgage products, although these may have different interest rates.
The following table provides an overview of potential costs.
| Remortgage fee | Indicative cost | When it applies |
|---|---|---|
| Mortgage arrangement fee | £0–£2,000+ | Setting up a new mortgage deal |
| Booking or reservation fee | £100–£300 | Reserving certain mortgage products |
| Property valuation fee | £0–£500+ | When the lender requires a paid valuation |
| Solicitor or conveyancing fee | £350–£1,000+ | Legal work when changing lenders |
| Mortgage broker fee | £0–£1,000+ | If your broker charges a fee |
| Mortgage exit fee | £50–£300 | Closing an existing mortgage, where applicable |
| Early repayment charge | Often 1%–5% of the outstanding balance | Leaving a deal during its charge period |
These are illustrative ranges rather than guaranteed prices. Some fees can be higher, while many mortgage products include free valuation or standard legal services.
Understanding individual remortgage fees helps you compare lenders accurately. A mortgage with a low interest rate may look attractive, but arrangement charges and other expenses can reduce or eliminate the expected savings.
A mortgage arrangement fee, also known as a product fee, is charged by the lender for providing a particular mortgage deal. Some lenders offer products without arrangement fees, while others charge £999, £1,499 or more.
For example, imagine comparing a mortgage with a 4.5% interest rate and a £999 arrangement fee against another offering 4.7% with no arrangement fee. The lower-rate mortgage is not automatically cheaper because the saving depends on your mortgage balance, remaining term and the length of the deal.
Some lenders allow borrowers to add the arrangement fee to their mortgage rather than paying it upfront. However, this increases the outstanding loan balance and may result in additional interest.
Before accepting an offer, compare the total cost over the deal period rather than choosing a mortgage based only on the headline interest rate.
An early repayment charge, often abbreviated to ERC, is a penalty that may apply when you leave your existing mortgage before the specified charge period ends. It is particularly relevant for homeowners who want to switch during a fixed-rate mortgage deal.
These charges are often calculated as a percentage of the outstanding mortgage balance. For example, if you owe £180,000 and your lender applies a 3% early repayment charge, the penalty would be £5,400.
| Outstanding mortgage | 1% ERC | 3% ERC | 5% ERC |
|---|---|---|---|
| £100,000 | £1,000 | £3,000 | £5,000 |
| £150,000 | £1,500 | £4,500 | £7,500 |
| £200,000 | £2,000 | £6,000 | £10,000 |
| £250,000 | £2,500 | £7,500 | £12,500 |
These calculations are examples. Your lender may apply a different percentage or charging structure depending on the mortgage agreement.
The Financial Conduct Authority’s mortgage rules set requirements concerning early repayment charges. Before switching, request a redemption statement from your current lender to confirm the amount payable.
When moving your mortgage to a different lender, legal work is generally required to remove the existing lender’s charge and register the new lender’s interest in the property. A solicitor or licensed conveyancer normally handles this process.
For a straightforward remortgage, legal fees may cost several hundred pounds. However, some lenders offer free standard legal services as part of their remortgage packages.
More complicated cases can cost extra, particularly when you are adding or removing someone from the property ownership, dealing with unusual title arrangements or requiring additional legal documentation.
Always check whether the quoted fee includes VAT, Land Registry charges and other necessary expenses. This helps prevent unexpected costs before completion.
A new mortgage lender needs to assess your property’s value before deciding how much it is willing to lend. This valuation also helps determine your loan-to-value ratio, which can influence the mortgage rates available.
Many lenders provide free mortgage valuations, especially for straightforward remortgage applications. Others may charge a separate valuation fee depending on the property and the assessment required.
A basic mortgage valuation is designed primarily for the lender’s purposes. It should not be confused with a detailed property survey, which assesses the condition of the building. If your lender offers a free valuation, check whether additional charges could apply if a more detailed inspection is required.
A mortgage broker can help you compare lenders, understand mortgage criteria and manage the application process. Some brokers charge customers directly, while others receive commission from mortgage lenders.
A broker may charge a fixed fee, a percentage of the mortgage amount or nothing directly to the borrower. The charging structure should be explained before you agree to use the service.
Mortgage brokers can be particularly useful if you are self-employed, have irregular income or need help with a more complicated application. However, using a broker does not automatically guarantee a cheaper mortgage. Compare any broker fees against the potential benefits of the products and advice offered.
A mortgage exit fee, sometimes called a deeds-release or administration fee, may be charged when you close your existing mortgage account.
Not all lenders charge these fees, and the amount should depend on your mortgage agreement. Some homeowners may already have paid an exit-related charge when arranging their original mortgage. Before remortgaging, ask your existing lender whether an exit fee applies. If the amount differs from your original agreement, request an explanation.
To understand whether remortgaging saves money, consider a homeowner with a £200,000 repayment mortgage and 20 years remaining.
Suppose their current mortgage rate is 5.5%, and they can switch to a new deal at 4.5%. For this example, assume there is no early repayment charge and the new lender covers standard valuation and legal fees.
| Mortgage details | Existing mortgage | New mortgage |
|---|---|---|
| Outstanding balance | £200,000 | £200,000 |
| Interest rate | 5.5% | 4.5% |
| Remaining term | 20 years | 20 years |
| Approximate monthly repayment | £1,376 | £1,265 |
| Arrangement fee | £0 | £999 |
The new mortgage reduces the initial monthly payment by approximately £111. Over 24 months, the difference in payments would be around £2,664.
After deducting the £999 arrangement fee, the cash-flow difference would be approximately £1,665, assuming no other charges and that the fee is paid separately.
However, this is not the same as the full financial saving. Different interest rates also affect how quickly the mortgage balance reduces, so a proper comparison should consider the remaining balance after two years. The example is illustrative and does not represent a live mortgage offer.
Homeowners generally have two options when their mortgage deal approaches its end. They can move to a new lender through a remortgage or switch to another mortgage product with their existing lender.
Switching products with your current lender is commonly called a product transfer. This can be simpler because the lender already holds information about your mortgage and property. A product transfer may involve less paperwork and fewer legal requirements. However, the available mortgage deals are limited to those offered by your existing lender.
| Comparison | Product transfer | Remortgage |
|---|---|---|
| Mortgage provider | Existing lender | Usually a different lender |
| Legal work | Often unnecessary for a straightforward switch | Usually required |
| Valuation | Often simpler | Depends on the new lender |
| Arrangement fee | May apply | May apply |
| Available mortgage deals | Current lender’s products | Products from other lenders |
| Application process | Often simpler | May require additional checks |
The cheapest option depends on the complete cost of each deal. A new lender might offer a lower interest rate, but switching costs could reduce the benefit.
Before making a decision, ask your existing lender for its available product transfer options and compare them with suitable remortgage deals.
The best way to calculate remortgage savings is to compare the total cost of your existing mortgage with the alternatives over the same period.
Start by calculating the monthly repayments under each deal. Then include arrangement fees, broker charges, legal costs, valuation fees and any early repayment penalties.
You should also compare the outstanding mortgage balance at the end of the chosen period. This is important because a mortgage with lower monthly payments may not always produce the lowest overall borrowing cost.
For example, if switching reduces your monthly payments by £80, the payment difference over two years would be £1,920. However, if the remortgage involves £2,500 in fees, the lower payments alone would not recover the switching costs within that period.
Understanding how to manage your money better can also help you assess whether the new repayments fit your wider financial responsibilities. Mortgage affordability should be considered alongside household bills, savings and other essential commitments.
The MoneyHelper remortgaging guide provides additional guidance on comparing mortgage deals and understanding the costs involved.
Many homeowners begin comparing mortgage deals several months before their existing fixed-rate agreement expires. This gives them time to review available rates, prepare documents and complete the application process.
Some lenders allow borrowers to secure a mortgage offer months before the intended completion date. This can be useful if you want to avoid moving onto your current lender’s standard variable rate after your existing deal ends.
However, mortgage offer validity periods vary, and some products may have conditions affecting cancellation or changes. Always confirm these details before proceeding.
If your fixed-rate deal ends soon, ask your lender when any early repayment charge expires. Arranging the completion date carefully could help you avoid unnecessary penalties.
It may be possible to arrange a new mortgage before your existing fixed-rate deal ends without immediately paying an early repayment charge. However, completing the remortgage during the charge period could still trigger a penalty.
For example, if your mortgage deal expires in four months, you might apply for a new mortgage now and schedule completion for after the existing charge period ends.
This approach depends on the lender’s offer validity and your existing mortgage terms. You should confirm both before making a commitment.
In some circumstances, paying an early repayment charge may still be financially worthwhile if the new mortgage offers substantial savings. However, the calculation must include all switching costs and the uncertainty of future mortgage rates.
Reducing the cost of remortgaging requires more than finding the lowest advertised interest rate. The most effective approach is to compare the complete financial impact of each mortgage option.
A mortgage with a low interest rate and a high arrangement fee may be more expensive than a slightly higher-rate product without a fee. This is especially relevant for homeowners with smaller outstanding mortgage balances.
Calculate the total cost over the deal period before deciding which option offers better value.
Your current lender may offer a competitive product transfer that avoids some of the legal and administrative work associated with changing lenders.
However, you should still compare the available products with suitable deals from other lenders.
Some lenders include standard legal services and property valuations within their remortgage products. These incentives can reduce upfront costs.
Check the terms carefully because more complicated legal work may not be covered.
An early repayment charge can significantly increase the cost of switching mortgages. Planning your remortgage around the end of the existing charge period may help you avoid this expense.
Ask your lender for the exact date and amount rather than relying on an estimate.
Your loan-to-value ratio compares your outstanding mortgage balance with your property’s value. A lower ratio may make more competitive mortgage products available.
For example, a £180,000 mortgage on a property worth £300,000 represents a 60% loan-to-value ratio. If your property value increases or your mortgage balance decreases, your available mortgage options may change.
Extending your mortgage term can reduce monthly repayments, but it may increase the total interest paid over the life of the loan.
Using a monthly budget guide can help you decide whether the repayments are affordable without creating unnecessary long-term borrowing costs.
It is also worth reviewing your wider financial goals before remortgaging. For example, homeowners planning to retire early, reduce debt or build savings may benefit from comparing mortgage options against those priorities.
When applying for a remortgage, lenders usually need information about your identity, income, existing mortgage and financial commitments.
Employed applicants may need recent payslips and bank statements, while self-employed homeowners may be asked for tax calculations, tax year overviews or business accounts. Lenders may also review your credit history and assess whether the new mortgage repayments are affordable.
Checking your credit score and reviewing your credit report before applying can help you identify potential inaccuracies. However, lenders use their own credit and affordability assessment criteria, so a particular credit score does not guarantee approval.
Preparing the necessary documents early can make the application process more straightforward and reduce avoidable delays.
Remortgaging may be worthwhile if it reduces your overall mortgage costs, provides more suitable repayment terms or prevents you from moving onto a more expensive follow-on rate.
However, a lower mortgage rate does not automatically mean switching is the best financial decision. Arrangement fees, early repayment charges and the remaining mortgage term can significantly affect the outcome.
For homeowners who are approaching the end of a fixed-rate deal, comparing new mortgage products with the current lender’s offers is a sensible starting point.

Ultimately, the right decision depends on your mortgage balance, income, available products and long-term financial plans. If your circumstances are complicated, consider seeking advice from an appropriately authorised mortgage adviser.
Remortgaging may involve little or no upfront cost with a suitable fee-free product. However, arrangement fees can reach £1,000–£2,000 or more, while legal fees, broker charges and early repayment penalties may increase the total.
Legal work is generally required when moving your mortgage to a different lender. Some lenders include standard legal services in their remortgage packages, meaning you may not need to pay a separate solicitor fee.
Some lenders offer mortgage products without arrangement fees and include free valuation and standard legal services. However, you should still check whether your existing lender charges an exit fee or early repayment penalty.
Early repayment charges are often calculated as a percentage of the outstanding mortgage balance. For example, a 2% charge on £200,000 would be £4,000. The actual charge depends on your mortgage agreement.
A product transfer with your existing lender can be simpler and may avoid certain costs. However, another lender could offer a more competitive overall deal, so it is worth comparing both options.
Some lenders allow borrowers to add arrangement fees to their mortgage balance. This reduces the upfront payment but increases the amount borrowed and may result in additional interest.
A straightforward remortgage may take several weeks, although the exact timeframe depends on the lender, application complexity and legal work required.
A new mortgage application may involve a hard credit search, which can temporarily affect your credit profile. The impact depends on your circumstances and the scoring system used by the credit reference agency.
Yes. An increase in your property’s value may reduce your loan-to-value ratio, potentially making different mortgage products available. However, lenders will rely on their own valuation and affordability assessments.
Saving £100 a month could reduce your payments by £2,400 over two years. However, you should subtract switching costs and consider the outstanding mortgage balance at the end of the period before deciding whether the new deal offers better value.
Understanding how much it costs to remortgage in the UK is essential before switching mortgage deals. Arrangement fees, legal charges, valuation expenses and early repayment penalties can all influence whether a new mortgage actually saves money.
Rather than focusing only on the lowest interest rate, compare the total cost of each mortgage over the same period. Consider your monthly affordability, remaining mortgage balance and any additional charges.
