I Had a Genetic Test After the Policy Started

If you took a genetic test after taking out life insurance, the short answer is reassuring: there is nothing you need to tell your insurer, and the result cannot be used against the cover you already hold. A predictive genetic result — one that estimates a future risk in someone who has no symptoms — sits outside what a UK insurer is allowed to ask for while your policy runs. Your premium does not change, your sum assured does not change, and you are under no duty to report the test.

This surprises people, because almost everything else about insurance seems to reward disclosure. But an in-force life policy is a fixed contract. The health questions were asked once, when you applied, and your answers were accurate then. A test you take years later cannot reach back into an agreement that is already running. The insurer priced the risk it chose to carry, and it carries it.

The protection comes from the Code on Genetic Testing and Insurance, a UK-wide agreement between the Government and the insurance industry. It contains the clearest commitment in this whole area: a signatory insurer will not ask for, and will not take account of, a predictive genetic test result taken after your cover began. Below we follow that through to the end — including the part that worries people most, which is what happens when a claim is finally made.

The short answer: nothing to report, nothing to unravel

Take the worry off the table first. Whatever a predictive test showed after your policy started — a raised risk, a reassuring result, or something you are still making sense of — it does not touch the cover you already hold. You are not obliged to volunteer it, and volunteering it would change nothing, because the terms of an in-force policy are already settled.

The reason is that the duty to be accurate runs up to the moment cover starts, not forever afterwards. You answered the insurer's questions honestly at the time. Nothing about a later test makes those earlier answers untrue. So there is no gap to fill and no correction to make.

On top of that ordinary position, the industry has given a specific promise about genetics. It is worth reading in the round, and we have set out its history and current wording separately in what replaced the genetic testing moratorium in 2018. For a policy already in force, the practical effect is simple, and it is the same conclusion reached from a slightly different angle in tested after your policy started, and why they cannot ask: the result stays with you and your clinical team, and no further.

Why an in-force policy cannot be reopened

Most protection cover — level term, decreasing term, or a whole-of-life plan — is written with guaranteed premiums. That means the price was locked when the policy began and the insurer cannot raise it because your circumstances or your health later change. It is the whole point of buying cover early: you fix the terms while you can, and the insurer takes the risk that things get worse.

A smaller number of policies have reviewable premiums, but even those are reviewed against the pooled experience of a whole block of policyholders, not against a single person's new medical information. No mainstream term policy contains a clause letting the insurer re-underwrite you as an individual midway through, and a genetic test result is exactly the kind of individual information that clause would need in order to bite. There is no such clause.

So the mechanics and the Code point the same way. Even without any special rule for genetics, a change in your health after the start date does not have to be reported on a standard term policy, and cannot be used to re-rate it. The Code then adds a further, explicit layer specifically for predictive genetic results, closing off any argument before it can start.

What "predictive" means, and why it is the protected kind

The distinction that matters is between a predictive test and a diagnostic one, and it is worth getting right because the Code protects one and not the other.

A predictive test looks for an inherited gene variant in someone who has no symptoms, to estimate the chance of a condition developing in future. Tests for the BRCA1 and BRCA2 variants, for Lynch syndrome, or for Huntington's disease taken while healthy are the familiar examples. A diagnostic test is done to explain symptoms you already have, or to confirm a condition a doctor already suspects. The Code restricts predictive results. Diagnostic results are ordinary medical information, treated like any other finding on your record.

The line is not always where people expect. An investigation that reveals a condition you already have is diagnostic even if it involves your genes — an echocardiogram that shows hypertrophic cardiomyopathy, for instance, is a heart-imaging diagnosis, not a predictive genetic test, a distinction we unpick in why an echo showing HCM is not a genetic test. And newer tools sit in genuinely unsettled territory: whether a consumer polygenic risk score counts as a "genetic test" under the Code is not yet resolved, as we explain in is a polygenic risk score a genetic test. For a plain predictive test on an in-force policy, though, none of this changes the answer.

The single exception: Huntington's disease above £500,000

The Code carries one narrow carve-out, and it is worth stating precisely so you can see it almost certainly does not apply to you. A signatory insurer may take account of a predictive test for Huntington's disease, and only Huntington's disease, where the life cover applied for is above £500,000 in total.

Read the words carefully. The exception is about cover being applied for, and it aggregates the life cover you are seeking across policies. It does not reach back into cover you already hold. A policy you took out before any test, or below that level, is untouched by the exception whatever the amount. The exception only becomes relevant if you go looking for substantial new cover — which brings us to increasing what you have.

What happens when a claim is eventually made

This is the question that sits underneath all the others, usually unspoken: could a test I took quietly, years ago, be the thing that stops my family being paid? For a predictive genetic result taken after the policy started, the answer is no, and the reasoning is clean.

A life claim is assessed against the information you gave when the contract was made, or when it was last varied. That is the moment the insurer's questions were live and your duty to answer accurately applied. A predictive test you had afterwards was not something you were asked about, and — because of the Code — not something the insurer was even permitted to ask for. Information that could neither be requested nor was required cannot become the basis for reducing or refusing a claim.

It helps to separate this cleanly from genuine misrepresentation, which is a different thing entirely. The Consumer Insurance (Disclosure and Representations) Act 2012 governs what happens when someone gives a careless or a deliberate wrong answer at the point of applying. If you had no symptoms and no diagnosis when you applied, answered honestly, and the test came later, there is simply no inaccurate answer for anyone to point at. The claim rests on what was true when you signed, and what was true was true.

In practical terms, that means the people who will one day make the claim do not need to keep a file of your genetic history or worry about disclosing it. When the time comes they will send the death certificate and the policy details, and the insurer works from the application it holds. If you want to make things easier for them, the useful step is not recording the test result but making sure they know the policy exists, who the insurer is, and — if it is written in trust — who the trustees are. That is what actually determines whether a claim is paid quickly.

If you later want to increase or replace your cover

The picture shifts, but only a little, the moment you ask for more. Increasing an existing policy's sum assured is a variation of the contract, and buying a brand-new policy is a fresh application; both usually bring a new set of health questions, and those questions attach to the new cover you are seeking.

Even then, the Code's core protection travels with you. On that new application the insurer still will not ask for or take account of a predictive genetic result — the only exception being the Huntington's-above-£500,000 case described above, assessed across the cover you are applying for. So the fear that a curiosity test years ago has quietly poisoned your ability to buy more cover is, for almost everyone, unfounded.

What is disclosable on any new application is ordinary medical information: current symptoms, diagnoses, treatment and monitoring. If you want to add cover — a bigger mortgage, a new child, a change in what your family would need — you can get life insurance quotes and let an FCA-authorised broker take you through the questions, confident that a predictive result is not among the things you are handing over. If a health condition is now in the picture, our guide to getting cover with a history or a condition sets out how that is actually assessed.

When the genetic result is not really the issue

There is an honest caveat to draw, because a test rarely happens in a vacuum. Sometimes the reason you tested was that symptoms had already appeared, or the result led you into surveillance, surgery or treatment. Those downstream medical events are ordinary medical information, and it is worth being clear about where they sit.

On your existing policy, they change nothing — a shift in your health after the start date is not reportable on a standard term contract, genetic or otherwise. On a future application, though, they would be relevant, because they are the kind of medical history any insurer asks about. The predictive result itself remains protected; the clinical events that followed it do not automatically share that protection. Keeping the two apart in your own mind is the single most useful thing you can do here: the gene result is shielded, the medical story around it is treated like anyone else's.

Scotland and Northern Ireland

The position is the same across the United Kingdom. The Code on Genetic Testing and Insurance is a UK-wide agreement, so a signatory insurer's commitments apply identically in Scotland and Northern Ireland as they do in England and Wales. There is no separate Scottish or Northern Irish genetics rule that cuts across it.

Two points of nuance are worth knowing rather than worrying about. The Code is a voluntary industry commitment rather than an Act of Parliament, though its signatories cover essentially the whole mainstream market. And the underlying consumer insurance law that governs how claims and misrepresentation are handled — the 2012 Act described above — applies throughout the UK, Northern Ireland included. Wherever you live, a predictive test taken after your cover began stays your business. If you are weighing up cover with any kind of medical history behind you, the insurability guide is the place to start.

Frequently asked questions

Does a genetic test taken after my policy started affect it?

No. Under the Code on Genetic Testing and Insurance, signatory insurers will not ask for a predictive genetic result taken after cover began, and it does not affect existing cover. Your premium and sum assured stay as agreed, and there is nothing you need to report.

What if I want to increase my cover later?

Increasing cover is a variation, so fresh health questions are usually asked. Even then the Code's restriction on predictive genetic results still applies, apart from the Huntington's disease exception for life cover above £500,000. Ordinary diagnostic results and current symptoms remain disclosable.

Could my family's claim be refused because of a test I took?

A claim is assessed against the information given when the contract was made or varied. A predictive genetic test taken afterwards was not something you were asked about, and not something the insurer could have asked for, so it should not form the basis of a refusal.
