You Insured the Mortgage. But Who Insures the Move?

There's a moment in every house move — usually somewhere between the conveyancer's emails and the hire van booking — when you feel genuinely on top of things. Mortgage sorted. Solicitor briefed. Boxes labelled with an optimism that won't survive contact with the loft.

What almost nobody checks in that flurry? The life insurance.

It's the quietest piece of paperwork attached to your home, and it's also the one most likely to be wrong by the time you collect the new keys.

The Cover You Bought Isn't the Cover You Have

Here's the trap. When you bought your first place, you probably took out a decreasing term life policy alongside the mortgage. The cover amount drops in step with your loan balance, so if the worst happened, the debt would be cleared and whoever's left wouldn't be fighting the bank for the house.

That policy is attached to that mortgage. The one you've just paid off, or are about to pay off, with the proceeds of the sale.

When you move and borrow more — which most upsizers do, because that's rather the point of moving — your old policy keeps shrinking towards a number that no longer matches anything. Meanwhile, your new debt is bigger, your new home is pricier to run, and the gap between what your family would need and what your policy would pay widens every year you don't look at it.

It's not that the policy vanishes. It just becomes a solution to a problem you no longer have.

Who Falls Hardest

Two groups tend to be the most exposed.

New-build buyers. There's a gap between exchanging and completing on a new-build — sometimes six months, sometimes more. Your mortgage offer, and often your protection policy arranged alongside it, is priced and underwritten against the purchase as it stood. If your circumstances shift during that wait (a new job, a health diagnosis, a bump in the household headcount), your policy may no longer reflect reality — or may need fresh underwriting altogether.

Joint borrowers. A joint mortgage means two people are each wholly liable for the whole debt. If one of you dies without adequate cover, the survivor inherits the full mortgage alone. That's survivable on a two-bed in Rotherham with a modest loan. It's a very different story on the larger mortgage you took on for the four-bed. Joint policies also raise a question worth settling before completion: who owns the policy, and who is it meant to pay?

The Critical Illness Wrinkle

Life cover gets the headlines, but critical illness cover is where moves cause the most chaos.

Many critical illness policies are written for a specific loan amount at a specific point in time. If you remortgage to fund an extension or a move up the ladder, the payout — which might have cleared your old balance comfortably — could now cover barely half the new one. And unlike life cover, you can't simply top up a critical illness policy at will. You'll usually need fresh underwriting, which means fresh medical questions, and every year older makes the premiums steeper.

If you've had any new health conditions diagnosed since you last applied, a brand-new policy may exclude them or charge heavily for them. Which makes the existing policy you already hold more valuable than you think — one more reason not to let it lapse carelessly during a move.

The Remortgage Blind Spot

It's not just moving house. Every time your fixed deal ends and you remortgage — something millions of us are doing on two-year cycles — the same drift happens. A new product, a new balance, a new monthly payment. The insurance, meanwhile, sits frozen in 2021.

Lenders will ask whether you have protection in place. Few will check whether it's adequate. That question, inconveniently, is yours.

A Grip Checklist for Every Rung

Think of insurance as grip on the ladder — it's not what lifts you up, it's what stops a fall your savings can't cushion. Run through this whenever you move, remortgage, or your circumstances change:

1. Compare cover to debt. Write down your new mortgage balance next to your total life cover. If there's a shortfall, you've found your gap.
2. Add up the running costs. The mortgage isn't the whole exposure. Council tax, childcare, the boiler that will inevitably fail in February — a rough annual figure tells you whether you're underinsured beyond the loan itself.
3. Check the policy term. If your cover ends before your mortgage does, the final years are unprotected. Extend or replace before you complete.
4. Review the trust wording. Policies not written in trust can sit in probate for months. A quick word with the insurer or a solicitor can fix that for free.
5. Don't cancel before the replacement is live. Tempting as it is to tidy up direct debits mid-move, keep the old policy running until the new one is in force. A two-week gap is all it takes.
6. Re-run the joint conversation. Who'd stay in the house? Who'd cover it? The answer changes as the mortgage grows.

Ten Minutes That Matter

None of this is glamorous. Nobody celebrates the evening they updated a life insurance policy the way they celebrate the offer being accepted. But the whole point of climbing is that someone catching you matters as much as the climb itself.

So before the boxes go in the van, dig out the policy documents. Read the sum assured. Do the maths against the new balance. If the numbers don't line up, you've just saved your future self from the most expensive oversight on the ladder — the one nobody spots until it's far too late to fix cheaply.
