What happens to your life insurance when you remortgage

Q: Should I cancel my old policy and take a new one?

Usually it is better to keep an existing policy if it still suits, because a new one is underwritten at your current age and health and often costs more, sometimes with new exclusions. If you do need more cover, a top-up policy alongside the old one is often the tidier answer. Never cancel existing cover until any replacement is fully in force.

Short version: remortgaging doesn’t cancel or change an existing life insurance policy — it’s a contract with your insurer, not your lender. The thing to watch isn’t your cover disappearing; it’s cover that was built around the old mortgage quietly no longer fitting the new one. Here’s what actually changes, and what usually doesn’t.

Quick answer

The short version

Remortgaging leaves an existing policy untouched — same premium, term and sum assured. It sits with your insurer, so switching rate or lender doesn’t affect it.
You don’t need life cover to remortgage, and you’re not obliged to buy it from the new lender or their broker.
The real issue is fit. Borrow more, stretch the term or move to interest-only and cover sized for the old loan can end up too small or finish too soon — a decreasing policy most of all.
If your cover’s still broadly right, it’s usually better to keep it and top up than cancel and restart, because a new policy re-prices you at today’s age and health.

At a glance

How a remortgage affects cover you already have

What you change at the remortgage	Effect on your existing cover	What people typically do
New rate or new lender, same balance and term	None — the policy is unaffected	Nothing, beyond a quick check the cover still suits
Borrow more (larger balance)	A decreasing policy can fall below the new debt	Add a separate top-up policy for the difference
Extend the term (e.g. 20 to 30 years)	Cover may end years before the mortgage is repaid	Extend the policy or add cover for the later years
Move part of the loan to interest-only	Decreasing cover shrinks while the debt doesn’t	Switch that portion to level term
Reduce the balance or shorten the term	You may hold more cover than the loan now needs	Often kept anyway, as a buffer for the family

First, the reassuring bit

Your policy and your mortgage are two separate contracts

People often assume the two are joined at the hip. They’re not. Your life insurance is an agreement between you and the insurer; your mortgage is between you and the lender. Remortgaging — whether you’re moving to a new rate with the same lender or switching to a different one entirely — changes the loan, not the protection sitting behind it. The policy carries on exactly as before: the same monthly premium, the same end date, the same payout.

Two things can complicate that picture, and both are worth a two-minute check. Older policies were sometimes assigned to the lender as security — a legal charge over the payout. It’s uncommon on modern cover, but if yours was assigned to the old lender, that assignment may need updating when the loan moves; your insurer or adviser can confirm in a phone call. The other thing is knowing which type of policy you actually hold. What’s often sold as “mortgage life insurance” is really decreasing term life insurance with a friendlier label, and that detail drives everything in the next section.

Where it goes wrong

When a remortgage leaves your cover mismatched

The danger was never that remortgaging switches your cover off. It’s that a policy shaped around the old mortgage stops matching the new one, and you don’t notice until a claim. A handful of situations account for most of it.

If you borrow more — a bigger house, a bit of extra for the kitchen — a decreasing policy keeps falling on its original schedule and can end up below the larger balance. If you stretch the term, say from 20 years to 30 to bring the payments down, a policy that ends at year 20 leaves the last decade with no cover against the loan at all. And if you shift part of the mortgage to interest-only, decreasing cover — which is designed to shrink alongside a repayment balance — can leave a shortfall, because the debt itself no longer reduces. None of these break the policy. They just quietly open a gap between what you owe and what would pay out.

The costly mistake to avoid

Should you cancel the old policy and start again?

Usually not. When the mortgage changes it’s tempting to bin the old cover and take something fresh, especially if the new lender or a broker is waving a policy under your nose. Be careful here. A brand-new policy is underwritten at your current age and health, so it tends to cost more than the one you took out years ago — and anything that’s cropped up since, from a diagnosis to new medication to a higher BMI, can load the premium or bring exclusions. That older policy is often quietly one of the best-value things you own.

The calmer route, when your existing cover is still broadly right, is to keep it and bolt on a separate top-up policy for whatever extra the new mortgage needs. Our how much cover calculator helps you work out the gap. One rule holds whatever you decide: never cancel the old policy until any replacement is fully in force — a few weeks with no cover is exactly when families get caught out. And if you do hold cover to clear a mortgage, it’s worth checking whether writing it in trust would get the money to your household faster. This is general information, not a recommendation about your own policy.

Common questions

Life insurance and remortgaging: FAQs

Does remortgaging cancel my life insurance?

No. Your life insurance is a separate contract with your insurer, not your lender, so switching rate or moving to a new lender leaves it in force with the same premium, term and payout. The only thing worth reviewing is whether the cover still matches the new loan. This is general information, not advice.

Do I need life insurance to remortgage in the UK?

No. Life insurance is not a legal requirement to get or keep a mortgage, though a lender or adviser may suggest it. Buildings insurance, by contrast, is normally a condition of the mortgage. Whether life cover is right for you depends on your own circumstances.

Do I have to buy cover from my new lender?

No. You can arrange life cover with any insurer or through a broker of your choosing, and you’re under no obligation to take a policy offered alongside the mortgage. Comparing across the market can help you find suitable cover at a fair price. This is information, not a recommendation of any particular route.

I’m borrowing more — is my existing cover still enough?

It might not be, particularly with a decreasing term policy, which keeps reducing on its original schedule and can fall below a larger balance. A common fix is to keep the existing policy and add a separate top-up policy for the extra borrowing, rather than replacing what you have. Working out the gap first helps.

Should I cancel my old policy and take a new one?

Usually it’s better to keep an existing policy if it still suits, because a new one is underwritten at your current age and health and often costs more, sometimes with new exclusions. If you do need more cover, a top-up policy alongside the old one is often the tidier answer. Never cancel existing cover until any replacement is fully in force.

My policy is assigned to my old lender — what happens now?

Assignment is uncommon on modern policies, but if yours was assigned to the previous lender as security, that legal charge may need to be released or updated when the loan changes. Your insurer or a solicitor can tell you whether an assignment is in place and handle any reassignment. It doesn’t affect the cover itself.

If I extend my mortgage term, do I need to extend my cover?

Possibly. If the policy ends before the new, longer mortgage is repaid, the final years would be unprotected against the loan. You can sometimes extend an existing term policy, or add cover for the later period. Check the policy’s end date against the new mortgage term and close any gap.
