You can usually get travel insurance if you have asthma, but the cover you're offered depends on how severe or unstable your condition is and whether you declare it. Expect three possible outcomes when you declare asthma: full acceptance, acceptance but with a loading (a premium increase), or an exclusion for asthma-related claims.

How insurers treat declared asthma

Insurers treat asthma as a pre-existing medical condition. That means they need information about your past and current symptoms, medication and treatment in order to underwrite the risk. The simplest cases are people who take a single preventer or reliever inhaler, have had no recent attacks and haven't needed unscheduled care. Those travellers are often accepted onto standard policies without extra cost.

More complex cases attract a loading or an exclusion. A loading is an extra charge added to your premium because the insurer judges you more likely to make a claim. An exclusion is a clause in the policy that says the insurer will not pay for anything related to your asthma. Neither outcome is unusual; what matters is knowing which you'll be offered before you travel.

Screening questions to expect

Insurers want a concise clinical picture. You'll be asked targeted questions intended to separate stable, well-controlled asthma from unstable, recently treated or complicated asthma. Expect a mix of yes/no questions and fields for short details.

Common questions include whether you:

  • are taking regular inhalers or other medication for asthma
  • have needed oral steroids, an emergency department visit or hospital admission for asthma
  • have had a change in medication or dosage recently
  • use a written asthma action plan or peak flow monitoring
  • have other lung conditions alongside asthma, such as COPD

The most important detail for insurers is recent instability. They will usually want to know about any hospital treatment, courses of oral steroids, asthma attacks requiring unscheduled care, or significant medication changes in the recent past. If you answer truthfully and provide clear dates and explanations, the underwriter can make an informed decision.

Accepted, loading or excluded: what leads to each outcome

There is no single line that separates the three outcomes, but some patterns recur.

Accepted without loading

If your asthma is controlled on a stable regimen, you have no recent emergency treatment and you're not planning high-risk activities, many insurers will accept you at standard rates. Evidence that helps this case includes a GP or specialist note confirming stability and a history of no recent exacerbations.

Accepted with a loading

Loadings appear when the insurer judges you to be at higher-than-average risk. Typical triggers are a course of oral steroids in the past year, a change in preventer medication, or a single emergency attendance for breathing problems. A loading means your policy will still cover asthma-related treatment but you pay more for that cover.

Excluded

An exclusion is most likely if you have had repeated recent admissions, intensive care, or if you are awaiting treatment such as hospital assessment or surgery related to your lungs. Insurers will also exclude asthma where it sits alongside other serious respiratory disease. An exclusion may be limited to asthma-related claims, leaving the rest of the policy intact for unrelated events, or it can be a broader refusal to provide cover at all.

Common policy limits and phrases to check

Policy wordings vary, so read the medical and exclusions sections carefully. A few things are worth checking every time because they commonly catch people out.

  • Definition of pre-existing conditions  see the policy's definition to know what you must declare. Some policies define it as any condition you have ever had; others refer to treatment in a recent time period.
  • Emergency medical expenses  find the monetary limit and whether evacuation or repatriation is included. The wording will tell you how vast a bill the insurer will consider.
  • Excess  this is the amount you pay towards each claim. Check whether the excess applies per person or per claim.
  • Activity exclusions  if you plan to snorkel, hike at altitude or take part in other exertional activities, check whether the policy excludes claims arising from strenuous or adventure activities.
  • Cancellation cover  see whether cancellation for a deterioration in your asthma before travel is covered and what proof is required.

If any of those points are unclear, phone the insurer and get the answer in writing. That written clarification can be vital if you later need to claim.

Practical steps to improve your chances of cover and claims being accepted

Stability shows. The clearest single thing that helps is neat, recent documentation that proves your asthma is controlled. Preparation also reduces the chance of problems while you are away.

  1. Get a concise GP letter or specialist summary. One paragraph should state diagnosis, current medication (with dosages), date of last exacerbation requiring unscheduled care, and an overall assessment of stability.
  2. Carry your repeat prescriptions and medication in the original packaging. Pack a copy of the prescription and an up-to-date medication list showing generic names, doses and times.
  3. Take more inhalers than you expect to need. Aim for at least the length of the trip plus enough days to allow for delays, and keep them in carry-on luggage.
  4. Bring a written asthma action plan and, if you use one, peak flow records indicating stability in the months before travel.
  5. Arrange for a travel-appropriate supply of oral steroids if your clinician thinks a rescue course is sensible. Do not start steroids pre-emptively without clinical advice.
  6. If you use a spacer, carry that too. Having the equipment you use daily reduces the risk of deterioration abroad.
  7. Keep records of any medical appointments or medication changes in the months before travel; these help when answering insurer questions and if you need to claim.

These steps make a difference at two points: when the insurer assesses your declaration before travel, and if you later make a claim. Clear, contemporaneous evidence that you were stable reduces the chance an insurer will argue a claim arose from an undeclared deterioration.

What to do if your claim is denied or you were declined cover

If an insurer declines your application or rejects a claim, don't panic. There are practical steps that improve the odds of a successful appeal or finding alternative cover.

  1. Ask for the reason in writing. A clear explanation of the underwriting decision or the ground for refusal is the foundation for any appeal.
  2. Gather supporting clinical evidence. Your GP or specialist can provide letters, test results or a chronology of events that explain stability or the exact nature of the problem.
  3. If you think the insurer has misunderstood a date or treatment, point that out and supply corrected documents promptly.
  4. Consider a specialist medical screening service or broker. They can read the insurer's reasons and shop the market for alternative policies to cover a condition an ordinary insurer excluded.
  5. If you still have an unresolved complaint against the insurer, follow the company's internal complaints procedure and, if appropriate, escalate to the independent ombudsman or regulatory body in your country.

Successful appeals commonly rest on a misunderstanding: a missed date, a medication with a different name, or the absence of a short explanatory GP letter. Fixing those small gaps often turns a refused claim into a paid one.

Special situations: activity, destination and length of trip

Your policy and the underwriter will also consider what you plan to do and where you plan to go. A short city break in a country with good healthcare presents a different risk to a remote trekking trip in a region with limited services.

If you plan exertional activities, competitive sport, or travel to high altitude, declare those plans. These activities can trigger exclusions or require a specialist policy that covers exertion-related respiratory problems. Likewise, longer trips or round-the-world itineraries attract more scrutiny because they raise the chance of your condition flaring while away.

If you will be travelling where medical evacuation is the only option for serious care, make sure evacuation cover is explicit. Evacuation can be the single biggest cost in a medical incident, and policies differ on whether and how they will fund it where a pre-existing condition contributed to the need.

Worked example: planning and outcomes for a typical trip

Say you have moderate asthma, controlled on a preventer inhaler and a reliever; you had one course of oral steroids and a single emergency department attendance 10 months ago; you're planning a two-week holiday in southern Spain involving a day-trip inland. This is how to approach cover and what outcomes to expect.

First, prepare documentation: a GP letter confirming diagnosis, medication list and a statement that your last exacerbation was 10 months ago and that your asthma is currently stable; a copy of your asthma action plan; and two spare inhalers in carry-on baggage. These items make it straightforward for the insurer to understand your risk.

Next, when you fill in the insurer's medical screening questions, answer clearly and put the ED attendance and steroid course on the form with dates. Attach the GP letter. With that picture, three likely underwriting decisions are possible:

  • Accepted without loading: if the insurer judges the single event 10 months ago to be an isolated flare and your GP letter confirms stability. Your cover will include asthma treatment while abroad.
  • Accepted with loading: if the insurer thinks that recent steroid treatment and ED attendance raise your future risk. Your policy will still cover asthma, but your premium is higher.
  • Excluded: if the insurer treats the ED attendance as evidence of unstable asthma, it may exclude asthma-related claims. You would still have cover for unrelated incidents but not for asthma treatment or evacuation linked to asthma.

If you receive an exclusion, you have choices. You can seek a specialist policy via a broker or accept the exclusion and top up your preparations: more inhalers, an agreed plan from your GP for emergency oral steroids, and access to medical advice in your destination. If you accept a loaded premium, consider whether the cost reflects the risk you're willing to carry for the holiday.

How to choose between policies and when to use a specialist broker

Your choice depends on three things: the level of cover you need, how much uncertainty you can tolerate, and price. If a standard insurer accepts you without loading, that is often the simplest route. If you are given a loading or an exclusion, a specialist broker can be worth the time: they understand medical underwriting language and have access to insurers who will underwrite conditions that generalist insurers won't.

Use an insurer's policy wording to compare policies, not their marketing blurb. Match the policy's medical sections to your priorities: cancellation and curtailment for a costly trip; emergency medical and evacuation if you are travelling where care is limited; and a low excess if you want less out-of-pocket expense at claim time. If you are unsure what to buy, a reputable specialist broker will explain why one underwriter charged a loading and another offered full cover.

It is appropriate to price shop, but don't allow price alone to decide. A cheap policy that excludes asthma-related claims is false economy if you need emergency treatment abroad.

If you need a quick policy and you are still within a window where cover for unforeseen changes matters, declare fully, choose the policy that provides the cover you want and, if necessary, accept a loading for peace of mind.

What to do if your asthma worsens while you are away

Know who to call. Your insurer's emergency medical assistance number is the first port of call for many travellers; they can advise on local treatment, arrange repatriation if necessary and tell you whether your intended provider will be accepted. If you seek treatment before telling your insurer, keep all receipts and medical reports to support any claim.

Practical steps at the first sign of deterioration: use your reliever as instructed, follow your action plan, contact local medical services if symptoms don't improve, and notify your insurer. If treatment involves a hospital stay, ask for an itemised medical report and keep copies of all bills. These documents are what the claims team will need.

What goes wrong most often and how to avoid it

The most common cause of trouble is non-declaration or incomplete declaration. Small things matter: omitting a recent steroid course, leaving out an emergency attendance, or failing to mention a medication change. Insurers look at medical records when dealing with a claim; inconsistencies give them grounds to decline payment.

Another frequent problem is inadequate medication supply. Flights are delayed, bags are lost, or local pharmacies don't stock particular inhalers. Carrying medications in your hand luggage, packing extras and having a GP letter that explains what you need makes practically every problem easier to solve.

Frequently asked questions

Do I have to declare my asthma when I buy travel insurance?

Yes. You must declare your asthma if the policy's medical screening questions ask about it. Failure to declare a pre-existing condition can lead to a claim being refused. If you are unsure how to answer, call the insurer before you buy.

Will an inhaler be covered if I need one abroad?

If your policy accepts your asthma, emergency treatment and medication for an acute episode will usually be covered under the medical section. Check the policy wording for what counts as emergency treatment and for any exclusions related to pre-existing conditions.

My insurer excluded asthma. Can I still get travel insurance?

Yes, you can often still buy travel insurance, but the asthma-related costs will not be covered by that policy. A specialist broker may be able to find an underwriter willing to cover asthma, sometimes at a loading. If cover is not available, take extra precautions: more medication, a clear action plan and a solid arrangement for medical assistance abroad.

How much extra medication should I take?

Take at least enough for the trip, plus a buffer for delays or lost bags. Many people plan for an extra week or two, but discuss exact quantities with your clinician. Keep medication in your carry-on in original packaging and bring a copy of the prescription.

Should I get a letter from my GP or specialist?

Yes. A concise letter confirming diagnosis, current medication with doses, last exacerbation and a statement on stability helps both underwriting and claims. It is the single most useful document an insurer will ask to see when assessing your risk.
