Should you switch mortgage protection if your health has changed?

Why this situation is different from an ordinary review

Most questions about switching mortgage protection are really pricing questions. This one isn't. When you first took out your policy, the insurer assessed you — your age, health and smoking status — and set a premium, possibly with a loading or exclusion, based on that one assessment. That assessment is not revisited while the policy runs. Your existing cover carries on exactly as agreed, regardless of what happens to your health afterwards.

The moment you apply for a new policy, for any reason, that assessment is taken again from scratch, based on today. If your health has moved in a difficult direction since you first applied — a new diagnosis, a change in medication, a period of ill health — a fresh application can come back loaded, restricted, or in some cases declined. None of that touches your existing policy, provided you keep paying it and don't cancel it. It's the one part of your finances that stays exactly as it was, precisely because nobody is allowed to reopen it.

The direction it moves matters, and it isn't always bad news

The same mechanism cuts both ways. If your health has improved since you first applied — twelve months smoke-free, a condition that's resolved, significant weight loss — a fresh application assesses you on today's evidence, which can mean materially better terms than you were offered originally.

There's a current, concrete example of this working in a reader's favour through no effort of their own. Since December 2023, a Voluntary Code of Practice from Insurance Ireland has required participating insurers to disregard a past cancer diagnosis on a mortgage protection application, once treatment ended more than seven years earlier — or five years if the applicant was under 18 at diagnosis — for cover up to €500,000 on a family home.

That code has just moved onto a statutory footing. The Insurance (Disregard of Certain Medical History and Miscellaneous Provisions) Bill 2026 — the "Right to Be Forgotten" legislation — has completed its passage through the Oireachtas, and will shorten the qualifying remission period to five years and raise the cover threshold to €650,000 once it is formally commenced. A commencement order, which brings a passed law into effect on a specific date, is still to follow, so the existing voluntary code remains the operative standard for now.

For a cancer survivor — or anyone whose condition is treated differently by underwriters today than it was when they first applied — the honest answer to "would I get better terms now" may genuinely be yes. But it's a question a proper comparison can answer. It isn't one to guess at either way.

What this means in practice

This is exactly the situation where reviewing carefully, rather than switching on a headline price, matters most — because getting it wrong isn't just a mild inconvenience. It can mean a genuine gap in cover.

• If you're unsure how your current health would be assessed, that's a question for a proper review, not a guess based on an online quote built for a generic applicant.
• If a new application comes back worse than hoped, you can simply not proceed with it — but only if you haven't already cancelled the policy you already have.
• Some existing policies include a conversion option or a Guaranteed Insurability Option, allowing you to adjust cover later without fresh medical evidence. It's worth checking whether yours does before assuming you'd need to reapply for everything from a standing start.

The one rule that matters most here

Never cancel an existing mortgage protection policy until a replacement has been fully underwritten, accepted and is in force. That rule applies to every switching decision, but it matters more here than almost anywhere else. If a new application comes back with a loading, an exclusion or a decline you didn't expect, a policy you've already cancelled can't simply be reinstated on its old terms. Keep the existing cover in place until the new one is a certainty, not a quote.
