Why Overpay
Every Extra Pound Comes Straight Off What You Owe
Your normal payment covers interest first. Anything extra goes directly against the balance, so you pay interest on less from that point on.
- ✓Less interest: a smaller balance means less interest every month after
- ✓Shorter term: keep your payment the same and you could be mortgage free sooner
- ✓Better rates later: a lower loan to value can open up cheaper deals when you remortgage
- ✓Flexibility: most lenders let you overpay up to 10% a year without a charge
How We Help
How to Overpay the Right Way
Five things to check before you start.
Check Your Allowance
Most fixed and tracker deals allow around 10% of the balance a year before an early repayment charge kicks in. Check your mortgage offer.
Keep a Safety Net
Money paid into your mortgage is hard to get back. Keep a few months of outgoings in savings first.
Clear Dearer Debt First
Credit cards, loans and car finance usually cost more than your mortgage. Pay those off first.
Pick Monthly or Lump Sum
Monthly overpayments start saving interest sooner. A yearly lump sum suits bonuses or irregular income.
Term or Payment
Ask your lender whether to shorten the term or lower the monthly payment. Many reduce the payment unless you tell them otherwise.

See What Overpaying Could Save You
Pop in your mortgage details and try a monthly overpayment, a yearly lump sum, or both.
Illustration only. Assumes your rate stays the same for the whole term and overpayments reduce your term rather than your monthly payment. Many lenders let you overpay up to 10% of your balance each year during a fixed or tracker deal without an early repayment charge, but check your own mortgage terms first.

Which Way Should You Overpay?
Both work. The best one depends on your income and your goals.
Monthly Overpayments
A set amount each month. Interest drops sooner, so it usually saves slightly more over time. Easy to budget for.
Talk It Through →Yearly Lump Sum
One payment a year from a bonus, savings or a windfall. Good if your income varies. Watch the 10% limit.
Get Straight Advice →Overpay or Save?
If your savings rate beats your mortgage rate after tax, saving may win. If not, overpaying often makes sense.
Check My Options →Remortgage Time
Overpaying before your deal ends can drop you into a lower loan to value band and a cheaper rate.
Book a Chat →Early Repayment Charges
Go over your allowance during a fixed deal and you could pay a charge of 1% to 5% of the extra. Always check first.
Ask a Question →Life Changes
Thinking of moving, starting a family or reducing hours? Keeping cash available may suit you better.

Mortgage Overpayment Questions, Answered
The things people ask us most about paying off their mortgage early.
Is it better to overpay monthly or yearly?
Monthly overpayments usually save a little more because the balance drops sooner. A yearly lump sum is fine if that suits your income. The difference is often small, so pick what you can stick to.
How much can I overpay without a charge?
Most lenders allow up to 10% of your balance each year during a fixed or tracker deal. Some allow less, some more. Your mortgage offer will tell you.
Should I reduce my term or my monthly payment?
Reducing the term usually saves the most interest. Reducing the payment gives you more breathing room each month. Your lender will ask which you want, or apply a default, so check.
Is it better to overpay my mortgage or save?
It depends on your mortgage rate, your savings rate and whether you have an emergency fund. If you have expensive debt, clear that first. We can talk this through with you.
Can I get overpayments back if I need them?
Usually not. Some flexible or offset mortgages let you borrow back overpayments, but most do not. That is why a savings buffer matters.
Does overpaying help when I remortgage?
Yes, it can. A smaller balance lowers your loan to value, and lower bands often come with better rates.
