Should I make Mortgage Overpayments in 2026?
Millions of families are constantly faced with the dilemma of whether to save or make overpayments on their mortgage. This is a monthly or yearly question for lots of mortgage borrowers who are in a fortunate position to be able to overpay their mortgage.

The current issue with mortgages is the obvious fact that interest rates are higher which means that you will naturally pay more than you would have done several years ago. Previously, mortgage overpayments weren’t as common because borrowers were only paying a fraction of the interest that they are paying now.
WARNING: It is very important to think very carefully about your financial situation before you make any overpayments on your mortgage and ideally you should have a rainy day fund. It’s important for parents to have proper financial protection for loss of income and serious illness or worse.
If you have disposable income then you should really be thinking about whether it is worth overpaying your mortgage. Even a relatively small overpayment can save you thousands over the term of your loan, especially if your mortgage rate is high.

What is a mortgage overpayment?
A mortgage overpayment is when a mortgage borrower pays more than their monthly or yearly mortgage repayment. Mortgage lenders will all offer a facility for a mortgage account holder to pay more than the typical repayment.
Overpayments are simply anything extra that you decide to repay to your mortgage lender either monthly or annually. Some mortgage borrowers pay an extra sum each month to reduce their mortgage balance, or you can pay a one-off payment each year if you prefer.
Note: According to official figures from Santander, its mortgage customers made over £100 million in mortgage overpayments in the first week of 2025. Santander also told us that its mortgage borrowers repaid more than £2 billion in 2024 in mortgage overpayments.
Is it a good idea to make mortgage overpayments?
Generally, it is a good idea to overpay your mortgage, as long as it is affordable and you don’t have other higher interest credit commitments to repay (e.g. credit cards, store cards, loans, other finance agreements). If you are in a financial position to be able to pay off your credit agreements, then you just need to prioritise which ones are best to repay first.
Simple rules for making mortgage overpayments
1. Should I repay other credit commitments?
If you have other commitments with higher interest rates, then you should ideally pay those off before you make mortgage overpayments to reduce any other interest charges (only do this where it is possible and there are no penalties for repaying the credit facility).
2. Should I put my money in to savings?
If and when you can get a better rate on savings, then you would be better off putting your money in to this. Generally, this isn’t going to be the case at the moment and especially when mortgage rates are as high as they are.
3. Can I afford to make mortgage overpayments?
Think very carefully about the short term and long term financial impact on your family if you pay more money to your mortgage. You should only do this if your family can afford to spare this money and it won’t have any impact on your lifestyle if anything happened to you or your partner.

What is the 10% mortgage overpayments rule?
Most mortgage lenders will allow borrowers to repay up to 10% of the remaining mortgage balance in 12 months without any penalty (e.g. Early Repayment Charge). We should also stress that this rule only applies during a Fixed or Discount rate period, and after that you are usually free to pay off as much as you like.
You should ALWAYS check your mortgage documents or speak to your lender to confirm that you have a ‘10% overpayments clause’ with your loan. There are some lenders or specific deals that either don’t have this or they might have a different percentage allowance.
The majority of families and mortgage borrowers won’t be able to repay more than 10% of their mortgage balance in 12 months in reality. This rule was set several years ago and has not changed since then, especially as more mortgage lenders have adopted the same strategy.
There are some circumstances where you may want to repay a lump sum off your mortgage, such as:
- Inheritance
- Selling another property, business, or asset
- Windfall
- Investment maturing
If one of these things happens to your family, then you might want to think about whether you make a mortgage overpayment, or wait until the end of your mortgage deal.
Note: your 10% will usually be calculated based on your mortgage balance at the beginning of that repayment year. For example, if your mortgage balance was £150,000 at the start of the year, then you would be able to repay an extra £15,000 in that year without a penalty or charge.
What happens if I want to repay more than 10% mortgage overpayment?
If your mortgage has a limit of 10% for mortgage overpayments and you still want to pay more than this, then you will usually have an Early Repayment Charge (ERC) to pay. This will typically be between 1% and 4% of the amount over your 10% allowance that you are paying to your mortgage lender.
You will be able to find your Early Repayment Charge on your mortgage documentation or you can contact your mortgage lender to find this out. The table below shows an example of a potential penalty for repaying more than your 10% allowance.
| Early Repayment Charge (%) | 1% | 2% | 3% | 4% |
|---|---|---|---|---|
| Lender Fee (£s)* | £200 | £400 | £600 | £800 |
*based on a mortgage balance of £200,000 and a mortgage overpayment of £40,000 (maximum allowed would be £20,000 under 10% rule).
How do mortgage overpayments help with remortgaging?
Mortgage overpayments can also be a big advantage to mortgage borrowers and families when the time comes to remortgage. Your mortgage balance will reduce when you make overpayments and this also means that the equity in your home will increase, which is a benefit when it comes to remortgaging.
By increasing the amount of equity in your home, you will automatically reduce the loan to value (LTV) ratio for your remortgage. If you manage to reduce enough to take your mortgage down by a 5% or 10% bracket, then your mortgage interest rate on your new mortgage will usually be lower.
Mortgage lenders will charge a certain rate for remortgage or new mortgage customers depending on the amount of equity they have. This will usually go down in 5% or 10% increments which will usually mean that your interest rate on a fixed or discount rate deal will also be lower.
