Interest-Only Mortgage Ending? Your Options in the UK (2026)

By Lisa Hayes · 19 October 2026

If your interest-only mortgage is ending and you have no way to repay the capital, you have four realistic routes: switch to repayment (fully or partly) with your current lender, ask for a term extension, release money from elsewhere such as savings or a pension lump sum, or sell the property and clear the debt from the proceeds. Selling is the one you control completely, and the earlier you start it, the more choice you keep. Do nothing and the lender can eventually go to court for possession, which is the worst of the five outcomes.

It's a common position. Typically it's someone who took out the loan in the early 2000s, was told "the endowment will take care of it" or "house prices will do the rest", and has just opened a letter with a date on it. The date is real. The panic is understandable. But the position is almost always more recoverable than it feels at 2am.

How many people are in this position?

More than the headlines suggest, though fewer than a decade ago. The Financial Conduct Authority (FCA) published analysis in August 2023, using data to the end of 2022, and the numbers are worth knowing because they show you're far from alone.

• 749,524wholly interest-only mortgages outstanding (end 2022)
• 244,179part interest-only, part repayment
• ~2minterest-only loans in 2015, so the pool has roughly halved
• ~22,000loans already past their end date and not repaid

Two other details from the same FCA research note stand out. About 55% of interest-only mortgages were taken out in 2008 or earlier, back when lenders weren't obliged to ask for a credible repayment plan. And the FCA's consumer research found a gap between hope and arithmetic: 36% of borrowers expected a shortfall, while modelling suggested closer to 46% might face one.

The maturity dates cluster too. The FCA's data shows smaller peaks around 2027 (about 51,000 wholly interest-only loans) and much bigger ones in 2031 and 2032 (roughly 72,000 and 77,000). If your end date sits in one of those years, you're not early, you're in a crowd. Lenders will be busy, so move first.

What actually happens when an interest-only mortgage ends?

Nothing dramatic happens on the day itself, which is part of the trouble. The term ends, the full capital balance becomes due, and from that point your monthly payments of interest no longer satisfy the contract. You owe the lot.

The FCA puts it bluntly: customers are responsible for the full repayment of the capital when the mortgage matures. There's no clause that quietly turns it into a repayment loan on your behalf.

What follows depends on the lender and on your behaviour. Here is the usual sequence:

1. Letters, months before. Most lenders write to you in the run-up asking how you plan to repay. Answer them. Silence is the thing that tends to push a lender towards formal action.
2. A conversation. If you've no plan, the lender will normally discuss options such as a conversion, a short extension or a managed sale.
3. A grace period, sometimes. Some lenders give a few months of breathing room while a sale completes, provided you keep paying and can show progress. This is discretionary. Don't assume it.
4. Formal arrears processes. If the balance isn't cleared and you're not engaging, the account is treated as being in default and the lender must follow the mortgage arrears rules, including the court Pre-Action Protocol, before it can start a possession claim.
5. Possession. A court decides, usually after giving you chances to put a credible plan in place. It is slow, but it is expensive, public and avoidable.

The point of that list is that you have plenty of leverage, but only if you use it early. A lender dealing with a borrower who says "I'm selling, here's the estate agent's instruction letter and the expected completion date" is in a completely different conversation from one dealing with a borrower who hasn't opened the post.

Can the lender make me switch to a repayment mortgage?

Not if you can't afford it. A lender can't simply force a repayment mortgage on you that your income doesn't support, and it can't cancel the loan early because you lack a repayment plan. What it can do is insist on the capital being cleared at the end of the term.

That sounds like cold comfort until you see the sums. Take a deliberately simple example. This is illustrative, not a quote: a £150,000 balance at 4.5%.

Look at what happens as the runway shortens. Stretch the debt over 20 years and it's an awkward but plausible increase. Squeeze it into three years because you left it late and it's a payment most households can't make. The lesson isn't subtle: time is the single most valuable thing you can buy, and it costs nothing to ask for it early.

Be aware, too, that getting a lender to extend an interest-only term is hard these days. Many lenders no longer offer new interest-only lending to people in your position, and they're under no obligation to extend. Some will agree a conversion of part of the balance to repayment and leave the rest interest-only for a defined period. It varies enormously by lender, which is why you must ask.

Your five options, compared honestly

Two of those need a note. On pension money, you can usually take up to 25% of a defined contribution pot tax-free from age 55 (rising to 57 from April 2028 under existing rules). Using it to clear a mortgage can be completely sensible. It can also leave you short at 80. Get advice from a regulated adviser before you do it, not from a forum.

On lifetime and retirement interest-only mortgages, these are genuine solutions for some older homeowners, and they're covered properly in our guide to selling a house with equity release. They are not a casual fix. If the aim is to clear this debt and keep living in the property into old age, that's a job for an independent adviser.

Is selling actually the right call for me?

It depends on how much equity you hold, which is a better predictor than your age or your income.

The FCA's data gives a reassuring picture of the typical borrower. The median estimated current loan-to-value on wholly interest-only mortgages is 37.4%, and about three-quarters are below 50% LTV. Only about 2% (roughly 15,000 loans) sit at 75% LTV or higher.

• Below 50% LTV about 75%
• 50% to 75% LTV about 22%
• 75% LTV or more about 2%

That tells you something quietly important: most people facing this problem have a lot of equity in the house. The FCA found that 65% of interest-only borrowers have £200,000 or more of equity and 49% have £300,000 or more. The debt is a cash-flow and timing problem, not a solvency problem. For that group, a sale, or a partial sale of the lifestyle (downsizing) clears the debt and leaves a pot behind.

Where you're in the minority, with low equity, a high LTV or sale proceeds that barely clear the mortgage, the sums need more care. If you suspect the sale price won't cover the balance, read our guide on selling a house in negative equity before you speak to anyone. And if you're already missing payments, our guide to selling in mortgage arrears covers what changes.

How much will I really keep after a sale?

Work backwards from the sale price, not forwards from the mortgage. The calculation is short, but people skip steps.

1. Realistic sale price. Use three recent sold prices on your street, not the asking prices. Our free house valuation guide explains how to check a figure properly.
2. Minus the redemption figure. This isn't the balance on your latest statement. Ask the lender for a formal redemption statement; our guide to the mortgage redemption statement shows what to check, including daily interest and exit fees.
3. Minus any early repayment charge. If you're still inside a fixed or discounted deal, you may owe a percentage of the balance. Our piece on the early repayment charge when you sell is worth five minutes. If the deal ends within months, waiting for that date can save four figures.
4. Minus selling costs. Agent fees, conveyancing, the energy performance certificate, and removal costs. These add up to a few thousand pounds even on a modest house.
5. What's left is yours. Plus, depending on who owns the house and what's happened to it, there may be a capital gains tax question. Your main home is normally exempt via private residence relief, but check if you've let part of it or been away.

A worked example, with made-up round numbers so you can plug your own in. You own a house worth £300,000 with a £150,000 interest-only balance and no early repayment charge. After agent and legal fees and moving costs of, say, £7,000 to £9,000, you'd expect to leave with around £140,000 to £143,000. That's money you didn't have a plan to find. The mortgage problem has become a deposit on somewhere smaller, or a pot to rent from, or the start of a retirement fund.

How do I talk to my lender without making things worse?

Call the number on your statement and ask for the team that deals with interest-only maturity, sometimes called the "term end" or "mortgage maturity" team. Ordinary customer service won't have the authority. Have these ready before you dial:

• Your account number, the end date and the current balance.
• A one-paragraph honest summary of your plan: for example "I want to sell, I expect to put the house on the market in March, and I'm asking whether you'll allow nine months."
• Your income and outgoings in outline, in case they ask what you could afford on repayment.
• A pen. Note the date, the name of the person you spoke to and what was agreed. Follow up in writing the same day.

The FCA says contacting your lender about this won't affect your credit rating, so there's no tactical benefit in hiding. If you are struggling with the payments themselves, you're entitled to forbearance under the FCA's mortgage rules (MCOB 13), and free debt advice from StepChange, Citizens Advice or MoneyHelper costs nothing. Use them, particularly if you're already behind. Pointing at a professional advice letter shows a lender you're serious.

One honest warning: an extension granted verbally and never recorded is worthless the moment the person on the phone changes jobs. Get it in writing.

What if my mortgage ended years ago and nothing happened?

It does happen. The FCA's research found about 22,000 loans (2.2%) already past their end date and not repaid, with just over half of them 12 months or less past maturity. Some borrowers sit there paying interest for years with the lender doing very little.

Two things to understand if that's you. First, being tolerated isn't the same as being safe. A lender can start formal action when it decides to, and portfolio sales to other firms change attitudes overnight. Second, there are legal time limits on lender claims (the Limitation Act 1980 sets different periods for different types of claim, with 12 years the figure often quoted for claims on a mortgage). But this is a technical area where the dates run from specific events, and I'd never tell anyone to rely on it as a plan. Take legal advice from a solicitor or an adviser at a free service, and treat limitation as a possible defence, not an exit strategy.

Could I have been mis-sold the mortgage?

Possibly, though less often than people hope. Claims usually succeed when a lender or broker recommended interest-only without checking that you had a credible way to repay, or when the repayment vehicle (an endowment, say) was sold to you as likely to cover the debt and later fell short.

If that sounds like your story, you can complain to the lender and, if it's rejected, to the Financial Ombudsman Service, which has time limits you must check. A complaint is free. A claims firm taking 30% of anything it wins is not. Importantly, acting on your mortgage now doesn't normally stop you complaining later, so don't let a possible claim delay a sensible sale.

What does a sensible sale timetable look like?

Here's how I'd plan it, counting back from the end date.

Selling through the usual route typically takes several months from listing to completion, longer if there's a chain. If you want to see what's realistic in your area, our guide on how long it takes to sell a house gives the honest range rather than the optimistic one.

When does a fast cash sale make sense?

Rarely as a first choice, and sometimes as a lifesaver. Here's my straight view.

A cash buyer is a good fit if you've left it late, if the end date is a couple of months away, or if the property is awkward to mortgage. In those cases certainty and speed have real value, and a cash sale can complete in a few weeks. Offers do usually come in below open-market value, because the buyer is taking on the risk and the work, so you must compare the net figure with what a slower sale would realistically deliver after fees and carrying costs.

It's a poor fit if you have 18 months in hand and an ordinary, mortgageable house. Then an open-market sale will usually leave you with more. The classic mistake is rushing to the fastest buyer because the letter is frightening, not because the numbers demand it.

If speed is the priority, our sell house fast guide compares routes and what each one really costs.

What if I'm already worried about repossession?

Then speed and paperwork matter more than anything else. If you've received a court claim form or a hearing date, don't ignore it. Go to the hearing; courts regularly adjourn or suspend possession to let a genuine sale go through. Our stop repossession page sets out where to get free help urgently, and the guide to selling to avoid repossession covers the legal steps in more detail.

Bring evidence to any hearing: a signed agent's instruction, a valuation, your conveyancer's details, a viewing log. A judge deciding whether to give you time wants proof the sale is real. "I'm going to sell" without paper is not proof.

Common mistakes I'd urge you to avoid

• Waiting for the lender to chase you. They might not, until they do, and then the tone changes.
• Believing house price growth will bail you out. It may have. Check actual equity today, not the figure you remember.
• Taking the first quick-sale offer without comparing. A single offer is a price, not a market.
• Ignoring the redemption figure. Statements show a balance; the lender wants a redemption sum with accrued interest and fees.
• Raiding a pension without advice. It's your income at 75. Be sure.
• Paying a claims firm upfront. You can complain directly for nothing.
• Agreeing things verbally. Put every concession in writing and keep copies.

Frequently asked questions in short

Will the bank take my house the day the term ends? No. Possession is a court process with set steps, and lenders generally prefer a managed repayment or sale. But the debt is due, so engage early.

Can I just carry on paying the interest? Sometimes lenders tolerate it for a while, but there's no right to. Treat it as borrowed time, and don't assume the arrangement will survive a change of lender or policy.

Do I have to move out to sell? No, most people stay until completion. Buyers prefer to see a lived-in home that is clean and well presented, and you avoid paying for an empty property.

Does downsizing really solve it? If your equity is healthy, it often does, and it can leave a pot behind. Do the costs-of-moving sums first, including stamp duty on the next purchase.

Where to go from here

If you take one thing away: this is a deadline problem more than a money problem, and you have the most choice today. Get your redemption figure, find out whether you face an early repayment charge, and then see what the house would fetch both on the open market and from a cash buyer. Once you can see both numbers side by side, the decision usually makes itself.

When you're ready to see what a cash buyer would pay, you can compare offers with Ready Steady Sell. It's free, there's no obligation, and it gives you a firm number to put next to the open-market route. You don't need to accept anything; you just need to know your options before the date on that letter arrives.
