£500,000 Totals Across Every Policy You Hold

The £500,000 figure everyone quotes for genetic testing and life insurance is not a limit on the single policy in front of you. It is a limit on your total life cover. Every policy you already hold counts towards it — including existing cover taken out with a different insurer, and often cover arranged through work or alongside a mortgage. The new application is measured against the whole picture, not against its own sum assured in isolation.

This matters to one specific group of people: those at risk of Huntington's disease. It is the only condition a UK insurer may ever ask a predictive genetic test result for, and only once your life cover crosses that £500,000 line. Because the threshold is a total, a modest new policy can tip your combined cover over the line even when that policy on its own is nowhere near £500,000.

So the question — does the £500,000 genetic testing limit include existing cover — has a plain answer. Yes. The number is measured against everything added together. Understanding how the aggregation works, before you fill anything in, is the difference between staying comfortably below the threshold on purpose and crossing it by accident.

The short answer: it is a total, not a per-policy figure

The Code on Genetic Testing and Insurance — the agreement between the UK government and the insurance industry that governs all of this — sets its financial limits in terms of the total amount of cover, not the value of any one contract. For life insurance that total is £500,000. Below it, a predictive genetic test result cannot be asked for or taken into account at all. Above it, one narrow exception opens up, and it applies to Huntington's disease alone.

The word that does the work is total. It means the insurer is not asking "is this policy worth more than £500,000?" It is asking "once this policy is added to everything else on your life, does your combined cover exceed £500,000?" Those are different questions, and people who assume the first one are the ones caught out by the second.

It is worth being precise about the scope, because the rule is narrower than the anxiety it causes. This is the one place in the whole system where a predictive result can ever be requested. If you want the underlying rule set out on its own, we have covered the single line in the Code that names Huntington's and only above £500,000 separately. This page is about the arithmetic that decides whether you are over that line in the first place.

What "total cover" actually adds up

When an insurer works out your total life cover, it is looking at the sum of the death benefits payable on your life across the policies you hold and the one you are applying for. In practice that means adding together things that people rarely think of as a single pile of money.

A straightforward example, using round numbers to show the mechanism rather than any real quote: if you already hold £300,000 of level term cover with one company and you now apply for £250,000 with another, your total is £550,000. The new policy is well under the threshold. The total is over it. It is the total the Code cares about.

Insurers' own consumer guidance is explicit that cover already held with other providers counts towards the figure. It is not confined to policies bought from the same company, and it is not reset each time you approach a new insurer. The threshold follows you and your total exposure, not the paperwork of any single provider.

What generally does not form part of a straightforward personal total is state provision, and the position on employer benefits depends on the arrangement. Death-in-service cover through a pension scheme and individual policies your own company holds on you are the grey areas most worth checking, because a large lump sum from work can quietly consume a lot of headroom before you have applied for anything personally.

Why the threshold is written as a total

The logic is not arbitrary. The whole architecture that replaced the older arrangements — set out in what replaced the genetic testing moratorium in 2018 — was designed to stop people at risk of a serious inherited condition being frozen out of protecting their families, while giving insurers a single, tightly drawn exception for the very largest policies.

If the limit were per policy, that design would collapse. Someone could assemble £2m of cover in four separate £499,999 tranches and never once cross a threshold. Making it a total closes that door. It also means the protection below the line is genuine: for the overwhelming majority of applicants, whose total cover sits under £500,000, a predictive result simply never enters the conversation, no matter how many policies make up the total.

The trade-off is the one this article exists to flag. A total that protects the system also means your headroom is shared across everything you hold. Each new policy uses some of it up.

How an insurer knows what else you hold

It knows because it asks. Applications routinely include a question about what other life cover you already have and whether you intend to keep it. This is not the insurer prying into your medical file — it is a question about your own financial arrangements, which you are the person best placed to answer.

Answering it accurately falls squarely within the duty of reasonable care not to make a misrepresentation, set out in the Consumer Insurance (Disclosure and Representations) Act 2012. You are not expected to recite policy numbers from memory, but you are expected to give an honest and careful account of the cover you hold. An unmentioned policy that surfaces later is the thing that causes trouble, not a total that was declared openly at the outset.

It is a common worry that declaring other cover somehow exposes your health information across companies. It does not work like that. Telling an insurer the amount and existence of another policy is a world away from giving it access to your records — the mechanics of what a life insurer can and cannot obtain about your health are covered in what a UK life insurer can actually see about your medical record, and the two things are governed quite separately.

The policy you are about to replace

A frequent and reasonable situation: you are not stacking cover, you are swapping it. You hold an older policy, you have found a newer one, and you plan to cancel the old one once the new cover is in force. Does the old policy push you over the total in the meantime?

It should not, provided you handle it openly. If a policy is genuinely being replaced, say so on the application. State the amount and the date it will end, and make clear the new cover is intended to take its place rather than sit alongside it. Insurers deal with replacements as a matter of routine, and a declared replacement is treated as what it is.

The failure mode is silence. An old policy you meant to cancel but never mentioned, discovered later, looks very different from the same policy explained up front. The honest version costs you nothing but a sentence on the form. The unexplained version is exactly the kind of loose end that gets pulled on if a claim comes early.

Business cover on your life counts too

People think of the threshold in terms of the family policy that pays off the mortgage. But cover written on your life for a business reason is still cover on your life, and it can eat into the same total in ways that are easy to overlook.

If your employer or your own company holds a policy on you — key person protection, a shareholder or partnership arrangement, relevant life cover — that sum can be large, and it may bring your combined cover closer to the line than your personal policies alone suggest. Whether a particular business policy aggregates with your personal cover for the purpose of the threshold is not something to guess at; it is set out in how key person cover on your life interacts with the genetic testing limit. If you are at risk of Huntington's and a business is arranging significant cover on you, that is the moment to check the total, not after the fact.

What this means if Huntington's is in your family

For most people reading this, the practical upshot is reassuring. If your total life cover, existing plus new, stays under £500,000, a predictive Huntington's result cannot be asked for and you do not have to volunteer it. Many people at risk deliberately arrange their cover to sit below the threshold for exactly this reason, and there is nothing improper about doing so — it is using the system as it was designed.

If your genuine protection needs push the total higher, the decision becomes a real one, and it is worth taking time over rather than stumbling into. You can weigh how much cover your family actually needs against where the line falls, and you can get life insurance quotes and have an FCA-authorised broker structure it with the total firmly in view. What you should not do is assume a single big number by fixating on one policy; the threshold does not see policies, it sees the sum of them.

One thing no online tool can do for you here is turn a family history into a personal price — a point we make in full in why no UK calculator can price your family history. The threshold is a fixed number in a code; your circumstances are not, and they deserve a proper conversation.

Does this differ across the UK?

No. The Code on Genetic Testing and Insurance applies across the United Kingdom, and so does the Consumer Insurance (Disclosure and Representations) Act 2012 that sits behind the disclosure duty. The £500,000 total, the Huntington's exception and the aggregation rule are the same whether you live in England, Wales, Scotland or Northern Ireland. What can differ between the nations is the wider law around estates and property once someone has died, but none of that touches how the threshold is calculated at the point you apply. On this specific question, the answer is genuinely UK-wide.

Frequently asked questions

Does the £500,000 limit include policies I already hold?

Yes. The threshold is expressed in terms of your total life cover, and insurer guidance to consumers states that cover already held with other providers counts towards it. A new application is measured against the whole picture, not against the sum assured on that one policy alone. If your existing cover plus the new policy comes to more than £500,000, you are over the line for these purposes even when the new policy on its own is small.

How would an insurer know about my other policies?

Applications routinely ask what other cover you hold and whether you intend to keep it. Answer accurately, because this is a question about your own arrangements and falls squarely within the duty of reasonable care under the Consumer Insurance (Disclosure and Representations) Act 2012. Declaring another policy tells the insurer the amount and existence of that cover; it is not the same as giving anyone access to your medical records, which is governed separately.

Does old cover I am about to cancel count?

If a policy is genuinely being replaced, say so on the application and state the amount and the date it will end. Insurers deal with replacements routinely, and a declared replacement is treated as one rather than as extra cover stacked on top. What causes problems is an unmentioned policy that surfaces later, not an intention explained clearly at the outset.
