No — don't leave a condition off your application. Your policy is issued on the basis of what you declare, so an omission can let an insurer reduce benefits, refuse a claim or cancel the cover later, exactly when you'd need it. Declaring is not the same as being declined: most conditions are handled routinely, and a specialist can place your cover with the insurer most likely to accept it. If you have something to mention, see pre-existing conditions and just tell us when you request a quote.
Let's be honest about where this question comes from. Almost nobody wants to commit fraud; the worry is usually more human than that. People fear that mentioning a past operation, some regular medication, or a managed long-term condition will price them out of cover or get them turned away — right when they're trying to tick the last box for a visa appointment. So the temptation is to keep quiet and hope it never comes up.
It's worth taking that worry seriously and answering it properly, because the reasoning that makes hiding feel safe is exactly backwards. Non-disclosure doesn't protect you — it quietly undermines the one thing you're paying for: cover that actually works when you need it.
Why hiding a condition backfires
Private medical insurance is a contract built on your declarations. When you complete the medical questionnaire, the insurer prices and accepts the policy based on the picture you give. If that picture is incomplete or inaccurate, the insurer may later be entitled to act on it — and the ways they can act are serious:
They may reduce or refuse a claim connected to the undisclosed condition, leaving you to pay for treatment yourself. They may cancel the policy altogether, which is catastrophic mid-residence and can leave you without the cover your visa relies on. And a cancelled or voided policy can make it harder to arrange cover afterwards. The cruel part is the timing: these problems surface precisely when you make a claim — that is, when you are unwell and least able to deal with a fight over paperwork.
Put plainly, hiding a condition doesn't remove the risk. It just moves the risk onto you, and hides it until the worst possible moment.
Declaring is not the same as being declined
Here's the reassurance that usually dissolves the temptation to hide: for most people, disclosing a condition is uneventful. Insurers assess health every day. A great many situations — stable long-term medication, a historic and fully-resolved operation, a well-managed condition — are accepted as a matter of routine, sometimes on standard terms and sometimes with specific terms attached to that one condition while everything else is covered normally.
Declaring simply means your application goes to underwriting with the full picture, so it can be placed with the insurer most likely to assess it fairly. That's a world away from being refused. And on the rare occasion one insurer does decline, it doesn't mean no cover exists anywhere — another may view the same situation differently, which is covered on our page about being declined. Our medical and underwriting guide walks through the whole process calmly if you'd like the detail.
What actually happens when you declare
The mechanics are less intimidating than people imagine. You answer the health questions honestly — current and past conditions, any medication, recent surgery or hospital admissions, sometimes height and weight. The insurer reviews it (this is called underwriting) and comes back with terms. Occasionally there's a follow-up question before a firm quote. That's usually the extent of it.
Being upfront early actually speeds things up, because we can go straight to the right insurer rather than getting a quote that later changes once the medical picture appears. So the disclosure you were dreading tends to make the process smoother, not harder.
If cost or acceptance is the real worry
Sometimes the concern behind the question isn't secrecy at all — it's money, or a fear that a particular condition is a dealbreaker. Those are fair worries, and they're better solved out in the open. Tell us what's relevant and let us do the work of matching you to suitable cover; that's exactly the kind of situation where specialist help earns its keep. What you should never do is buy a cheaper policy by leaving something off, because a policy that's void when you claim isn't cheaper — it's worthless.
Someone on long-standing blood-pressure medication worries it will sink their application, so they consider not mentioning it. In reality, stable, well-managed medication like this is one of the most commonly declared things and is frequently accepted without drama. Declaring it costs them nothing but a line on a form; hiding it could cost them a future claim. The choice only looks difficult before you know how ordinary the disclosure is.
The bottom line
Answer every medical question fully and accurately, and if you're unsure whether something counts, declare it and let the insurer decide. Honest disclosure isn't a hurdle to get past — it's the thing that makes your cover dependable, and it's what keeps your NLV insurance genuinely useful if you ever need to lean on it. When you're ready, tell us about any medical points when you request a quote and we'll place your cover properly.

Medical disclosure FAQs
Will declaring a condition mean I'm refused cover?
Usually not. Declaring is not the same as being declined. Many conditions are accepted, sometimes on specific terms. Declaring simply lets your application go to the insurer most likely to assess your situation well, and a specialist can help place it. See pre-existing conditions.
What happens if I leave a condition off the form?
It puts your cover at risk. If information is inaccurate or omitted, an insurer may later be able to reduce benefits, refuse a claim or cancel the policy — often at the moment you most need it to work. The policy is issued on the basis of your declarations.
I'm not sure whether something counts — should I mention it?
Yes. If you are unsure whether something is relevant, declare it and let the insurer decide. That is always the safer choice, and it protects the cover you are paying for. The medical questionnaire page explains what tends to be asked.
