Pension or pay off mortgage? Cashing in pension money to clear a loan is taxed differently from paying more into a pension, and each has costs to weigh.
Two questions sit inside this one: can a pension lump sum pay off the mortgage, and is extra money better spent on the mortgage or paid into a pension? There is no single answer, because it turns on your tax position, your lender's terms and when you will need the money. Pension Wise offers free, impartial guidance backed by government, while an FCA-authorised adviser can look across your pensions, tax bill, mortgage terms and plans in a single conversation. Asking for that costs nothing: use the form on this page.
Can you cash in your pension to pay off your mortgage?
Often, yes, if you are old enough and your provider offers it. The earliest age is usually 55, going up to 57 on 6 April 2028 except for ill-health retirement and protected pension ages, and your scheme's rules and your provider's options decide what you can do. The guide to taking money out of a pension covers the choices.
Under GOV.UK's rules a quarter of what has built up in a pension can usually come out tax-free, up to £268,275 in total. That cap is the lump sum allowance, added up across every scheme you belong to, and a protected allowance may raise it. The tax-free lump sum guide explains how it is worked out.
The rest is taxed as income, deducted before you are paid, and a large sum in one go may push you into a higher rate, with possible extra tax to settle after the tax year ends. A mortgage balance bigger than the tax-free amount means part of the clearing money would come from the taxable portion. The drawdown tax guide sets out how the rest is taxed.
Also, paying money back into a pension after withdrawing cash can bring a tax charge, GOV.UK warns. Pension recycling has the detail.
Does taking money from a pension limit what you can pay in later?
Yes, for some kinds of withdrawal. Taking taxable money flexibly can cut your annual allowance for defined contribution savings to the money purchase annual allowance. GOV.UK puts it at £10,000: you have gone over it if you have paid more than that into all your defined contribution pensions after first flexibly accessing your pension. GOV.UK's examples are cash from a flexi-access drawdown fund and cash taken straight from the pot.
Among the trigger events in HMRC's Pensions Tax Manual are the first uncrystallised funds pension lump sum and the first payment from a flexi-access drawdown fund. A lifetime annuity with entitlement on or after 6 April 2015 can trigger it too, if the contract allows payments to fall other than in prescribed circumstances. Once it is triggered, unused allowance from earlier years cannot be used against the £10,000 limit, which matters if you plan to keep saving after clearing the mortgage. The MPAA guide goes through it. Would your planned withdrawal set it off? That turns on your own pots and timing; an FCA-authorised adviser can trace which payment, if any, would trip it, and asking is as simple as the quick call-back form on this page.
Paying more into a pension instead of overpaying the mortgage
Paying in brings tax relief. GOV.UK says relief is available on private pension contributions of up to 100% of your annual earnings. Relief is often automatic, either added by the provider at the basic 20% rate or taken through the employer's payroll, but anyone paying Income Tax above 20% in a relief at source scheme has to claim the extra themselves, as the pension tax relief guide explains. The annual allowance is £60,000 for the current tax year, counts employer payments too, and shrinks for high earners and after flexible access.
MoneyHelper's guidance, as archived on 7 August 2025, put the case for this side: "With employer contributions and tax relief from the government, you might get more for your money in a pension than you’d save in mortgage interest." The key word is "might". Pension money is invested, so the pot can shrink as well as grow and may end up worth less than was paid into it. It is also usually out of reach until 55 (57 from 6 April 2028), whereas an overpayment cuts the debt straight away. If an ISA is the third option, the pension or ISA comparison covers it.
What overpaying the mortgage involves
Overpaying cuts the balance, so less interest builds up and the loan ends sooner, but free overpayment limits are set lender by lender. Santander's overpayment page, for instance, lets fixed-rate customers overpay up to 10% of the loan each calendar year without a charge, does not carry an unused allowance into later years, and allows unlimited overpayments off a fixed rate. Halifax puts its limit at 10% of the balance at the start of the year and adds that other lenders' limits may vary.
Such an allowance may not help someone clearing the whole loan at once: Santander says its 10% cannot be used when the mortgage is paid off in full. The charge itself is set by your own contract. FCA rule MCOB 12.3.1 (in force since 31 October 2004; section last updated 21 March 2016) allows only a charge that can be expressed as a cash value and is a reasonable pre-estimate of the lender's costs when a customer repays before the contract ends. Check the charge in your own offer or statement before moving any pension money.
If your mortgage is interest-only
The FCA's consumer story on interest-only mortgages (first published 2 May 2013, last updated 24 February 2016) explains that each monthly payment goes only on interest, so a separate plan is needed to repay the capital at the end. A pension lump sum can be that plan, subject to the tax points above. Anyone worried they cannot save enough in time was told to speak to the lender about other options.
Pension or pay off mortgage: weighing each route
| Point | Cash in pension to clear the mortgage | Overpay the mortgage | Pay more into a pension |
|---|---|---|---|
| What it can gain | Loan cleared, so no more payments or interest on it | Less interest; loan cleared sooner | Tax relief on contributions up to 100% of annual earnings |
| What it can cost | Only part usually tax-free (up to 25%, within £268,275); the rest taxed as income; a smaller pot to retire on | An early repayment charge above the lender's free limit (10% a year on Santander fixed rates and at Halifax) | Invested, so the value can fall; usually locked away until 55 (57 from 6 April 2028) |
| Later pension saving | Taxable flexible withdrawals can cut the allowance to £10,000 | Pension allowances untouched | Annual allowance of £60,000 for the current tax year, lower for some |
Questions about using a pension on a mortgage
Can I use pension drawdown to pay off my mortgage?
Drawdown can pay out cash, taxed as income beyond the tax-free part, and the first payment from a flexi-access drawdown fund can trigger the money purchase annual allowance. The drawdown guide explains how it works.
Does taking the 25% tax-free cash trigger the MPAA?
Usually not, if that is all you take: MoneyHelper's MPAA guide says it is usually not triggered by taking up to 25% as tax-free cash and either leaving the rest invested or buying a guaranteed lifetime annuity with it. Taking the whole pot in one go normally does trigger it, unless it is under £10,000 and paid under small pot rules, and HMRC's manual lists the first uncrystallised funds pension lump sum as a trigger event even though part of it is tax-free. Ask your provider exactly how it would pay the money before you take it.
Is there a calculator for pension against mortgage overpayment?
Halifax and Santander publish mortgage overpayment calculators, covering only the mortgage side. The pension side depends on your tax band, employer money and age; raise it when the adviser rings after you use the form.
Do I pay a penalty for repaying my mortgage early?
Possibly. It depends on your contract and on your lender's free overpayment limit, and a limit like Santander's 10% cannot be used to repay the whole loan.
Deciding between the pension and the mortgage
Tax, allowances, your lender's terms and your retirement income all bear on this, and neither route suits everyone. Pension Wise explains pension options without charge, and the retirement planning guide puts the choice in the wider plan. Prefer your mortgage and pensions looked at side by side?
