Book Your Offset Mortgage AppointmentWhat is an Offset Mortgage?
An offset mortgage is a flexible type of mortgage that allows you to link your savings or current account balances to your mortgage.
The money held in these linked accounts is set against your mortgage balance, so you are only charged interest on the difference. This reduces the amount of interest you pay over time. Please note: that some lenders may have restrictions on which accounts can be linked.
For example, if you have a mortgage of £250,000 and savings of £40,000, interest would only be charged on £210,000.
Your savings remain in your account and can be accessed at any time. Instead of earning interest, they work to reduce the interest charged on your mortgage.
In simple terms:
- You sacrifice earning interest on your savings
- In return, you reduce the interest charged on your mortgage
This can lower your monthly interest costs or, depending on the lender, help reduce the length of your mortgage term
0800 0320 316The principle is simple: by depositing your savings or having your everyday current account with the lender, the balances in these accounts can be used to reduce the overall interest paid on the mortgage, whilst keeping the money accessible. Many offset lenders calculate interest daily, so your savings can reduce the cost of your borrowing on an ongoing basis. Daily interest calculations mean your savings balance is checked every day, and the mortgage interest you pay is reduced each day by that savings amount. This makes your savings work harder because the reduction in interest happens daily and not just once a month or less often. Using savings in this way may also reduce the need to earn interest on those funds. The tax impact will depend on your individual circumstances, including your savings allowance and whether you would otherwise receive taxable interest. Some lenders have the facility for multiple accounts (such as current accounts, savings, and ISAs where permitted by the lender) but for the purposes of interest calculation, all balances are accumulated. Flexible deals in many cases allow you to make extra lump sum or monthly payments, take payment holidays and make underpayments.How Does an Offset Mortgage Work?
Offset Mortgages: Example Scenarios
To help you understand how offset mortgages work in practice, here are a couple of the most common scenarios we see:
Example 1: Reducing InterestYou have: Mortgage balance: £200,000 Savings: £30,000 You are only charged interest on £170,000. This means less interest is added each month, which helps reduce the overall cost of borrowing. |
Example 2: Shortening Your Mortgage TermYou have: Mortgage balance: £300,000 Savings: £50,000 You continue to make the same monthly payment, but because interest is calculated on £250,000, more of your payment goes towards the loan itself. This can help you pay off your mortgage earlier without increasing your monthly payments. |
Who Are Offset Mortgages Suitable For?
Offset mortgages are generally suited to borrowers who hold a meaningful level of savings or regularly maintain a strong balance in their current account. The more money you keep in these linked accounts, the greater the impact on reducing the interest charged on your mortgage.
They can be a good fit for people who want to keep access to their savings rather than using them to make a lump sum overpayment. Your money remains available if your circumstances change, which adds a level of flexibility that standard mortgages do not offer.
This type of mortgage also tends to suit those with a long-term view. If you are able to maintain your savings over time, the reduction in interest can build steadily and help lower the overall cost of borrowing.
A disciplined approach to saving is important. The benefits rely on keeping funds in your account, so regularly withdrawing large amounts may limit how effective the offset is. Withdrawing savings reduces the offset amount, causing interest payable to rise, which can diminish benefits quickly if balances fluctuate.
How Much Could You Save with an Offset Mortgage?
The amount you could save with an offset mortgage depends on several factors, including:
- Your mortgage balance
- Your savings balance
- The interest rate
In simple terms, the more you have in savings, the more of your mortgage balance is offset, which reduces the interest charged. However, the actual level of saving can vary depending on how the mortgage is set up and how your finances change over time.
How Offset Mortgages Save You Money
Some lenders allow you to use the interest savings to reduce your monthly payments, while others keep payments the same and shorten the mortgage term instead. Reducing the term can lead to greater overall interest savings, but it depends on your priorities and affordability.
Higher Savings, More Money Saved
Your savings behaviour also plays a part. If your savings remain consistently high, the benefit of offsetting is more noticeable. If your balance fluctuates or reduces over time, the impact will be lower.
Comparing Rates and Lender Calculations
It is also important to compare the interest rate against standard mortgage deals. Offset mortgages can come with higher rates, so the overall benefit depends on whether the interest saved through offsetting outweighs the additional cost of the higher rate.
Each lender calculates interest in their own way, often on a daily basis, which can influence how much you save. Small differences in calculation methods can add up over the life of the mortgage.
An advisor can help you review different scenarios and assess how an offset mortgage would perform based on your financial position.
Benefits and Considerations with an Offset Mortgage
When exploring an offset mortgage, it’s important to not only consider the benefits, but also the potential drawbacks of choosing this as an option. We’ve laid these out for you below:
Key BenefitsReduced Interest CostsBecause interest is calculated on a lower balance, you may pay less over the life of your mortgage. Potential to Repay Your Mortgage SoonerWith less interest to cover, more of your monthly payment reduces the capital. This can shorten your mortgage term. Access to Your SavingsUnlike overpayments, your savings remain available to withdraw at any time. Tax EfficiencySavings held in an offset account do not earn interest, so there is no savings interest to be taxed. This can be useful for higher rate taxpayers, where basic rate taxpayers may see less benefit here. We’d strongly recommend that you speak to a tax advisor if this is a significant part of your thinking around offset mortgages. |
Important ConsiderationsInterest Rates May Be HigherOffset mortgages can come with higher interest rates compared to standard deals. The benefit depends on how much you have in savings. Savings Need to Be SignificantIf your savings balance is low or inconsistent, the interest savings may not outweigh the higher rate. Less Lender AvailabilityLess lenders offer offset mortgages, but many mainstream and specialist lenders do consider.

Offset Mortgages vs Overpayments
Overpaying your mortgage and using an offset mortgage can both reduce the amount of interest you pay, but they work in different ways and suit different types of borrowers.
Overpayments
Typically when you make a mortgage overpayment, you use your savings to reduce your mortgage balance permanently. This means you will be charged interest on a lower amount going forward, which can reduce your monthly payments or shorten your mortgage term.
However, once your money has been used to overpay, it is no longer easily accessible.
How Offset Mortgages are Different
With an offset mortgage, your savings are not used to pay down the loan. Instead, they sit in a linked account and reduce the balance that interest is calculated on. This means:
- Your savings remain in your account
- You can withdraw them at any time if needed
- The level of interest you pay can change depending on your savings balance
This flexibility can be useful if you want to keep funds available for emergencies, future plans, or irregular expenses. However, the trade-off is often a higher interest rate.
The right option depends on how you manage your savings and how important access to your money is over the life of your mortgage.

Why Work With The Mortgage Broker?
Offset mortgages can be more complex than standard mortgage products, and getting the right advice can make a clear difference to the outcome. There’s a lot to consider, and mortgage applicants across the UK trust our advisors to guide them along the right path.
Fewer Lenders Offer Offset Mortgages
This means the range of options is more limited and not always easy to compare. The differences between products can go beyond the interest rate, including how savings are linked and how interest is calculated.
The Right Option Depends On How You Manage Your Savings
Two borrowers with the same mortgage and savings balance could see different results based on how consistently those savings are held and how the account is used over time.
Some Lenders Allow You To Link Multiple Accounts
This can increase the amount offset against your mortgage. Others have more restrictive criteria, so understanding these details is important when comparing options.
