Most people assume there's one age where mortgages simply stop. There isn't, but there also isn't a secret trick that makes age irrelevant. What actually happens depends on which lender, which product, and what you can evidence about your income once you're not working full time any more.
For a standard residential mortgage, 70 is the number that matters most, and it's a sensible one to plan around rather than a cautious guess you can safely ignore. Going beyond it is possible, but it means a different, more detailed conversation: evidencing the pension income that would support the mortgage, with the lender then sizing what you can borrow to that income, which is very often lower than your current salary. The two places age genuinely opens things up are buy-to-let, and the later-life products built specifically for this. There are also two different limits in play throughout: the age you are when you apply, and the age you'll be when the mortgage is due to finish. It's the second one that normally does the work.
Here's the honest picture, lender by lender where it's worth being specific, and in ranges where it isn't. Accurate as of October 2026. Always check current criteria with us before relying on a figure, because lenders do move these (more on that below).
What a "standard" mortgage will actually let you do
Mainstream lenders work to what's sometimes called a Maximum Working Age, the point at which they stop assuming you'll still be earning a salary. For most lenders that's 70, and that's the figure worth planning around, not 75 or 80.
To give two real examples rather than a vague range: TSB's standard cut-off for a repayment mortgage is 70. It will only consider stretching that to 75 if you can evidence a private or company pension already in payment, or committed to be in payment, by then, and even then what you can borrow is assessed against that pension income, not your current salary. Halifax works the same way. Its Maximum Working Age is also 70, and a full repayment mortgage only reaches 80 at the end of the term if your evidenced retirement income supports borrowing at that level. Interest-only borrowing is treated more cautiously across the board, most lenders stop that at 70 regardless of pension evidence.
So the honest pattern across the high street is this: 70 is the practical default, not a worst case. Going past it is possible, but it's a genuine affordability assessment on your pension income, not a formality, and the amount you can borrow usually drops when the income does.
What going past 70 actually involves
Stretching a mortgage past your working age isn't a special scheme, and it isn't just a form to fill in. A private or company pension forecast, a State Pension forecast from the Pension Service, or an annuity statement, each dated recently, is the minimum a lender needs before they'll even consider lending past that age. From there, what you can actually borrow is based on that pension income, not your current salary, and for a lot of people that income is lower than they expect. That's exactly why 70 remains the realistic planning number for most standard mortgages, rather than 75 or 80.
It's still worth raising this early in the conversation if your mortgage needs to run past your mid sixties, so you know where you genuinely stand rather than assuming either the best or the worst. Go in expecting an affordability conversation about your pension, not a rubber stamp.
Beyond the high street, and why age sometimes isn't the limit at all
Specialist lenders go further still, several push into the high 80s and beyond, well past anything a high street bank will quote you.
And for some people, the right product doesn't have a meaningful age ceiling at all. A Retirement Interest-Only mortgage doesn't have a fixed end date in the way a normal mortgage does. You pay the interest each month, the loan is repaid when you die, sell the property, or move into long-term care, and because there's no term to run out of, your age stops being the obstacle. What gets assessed instead is whether your pension income covers the monthly interest. We've covered RIO mortgages and the other later-life lending options in detail in Mortgages in Retirement, including how they compare to equity release.
Buy-to-let plays by different rules entirely
If you've ruled yourself out of a buy-to-let mortgage because of your age, it's worth asking again, because BTL lending works on a different basis altogether. Lenders are assessing whether the rent covers the mortgage, not whether your salary does, so your age matters far less than it does on a residential application.
TSB is a useful same-lender comparison: their own buy-to-let criteria let the mortgage run to 80 at the end of the term, a full five years later than their residential cap of 75. And the market has been moving further in landlords' favour. Nationwide's buy-to-let arm, The Mortgage Works, raised its own age limit at application from 70 to 75 this September, for first-time landlords, and set no maximum age at all for experienced landlords borrowing up to 70% of the property's value. Across the wider buy-to-let market, plenty of specialist lenders apply no age limit whatsoever once the rent comfortably covers the mortgage, for both personal and limited company applications.
The honest answer
There's no single number, because it depends which lender, which product, and whether you can evidence income beyond your working years. As a rough shape: 70 is the realistic number to plan around for a standard mortgage, with 75 to 80 possible only where your evidenced pension income supports it, specialist lenders and later-life products go well beyond that, and buy-to-let is more relaxed on age than almost anyone expects.
The numbers above are accurate as of October 2026, lenders do revise these criteria (the Nationwide change above happened mid-month), so treat this as the current shape of the market rather than a fixed table, and check with us before relying on a specific figure for your own application.
If you've assumed you're already too old, the better question is what you'd actually need to show a lender to prove otherwise. That's a five minute conversation with Debbie at DS Financial, not a guess.
