Does mild asthma affect life insurance premiums?

Mild asthma is one of the most common conditions an insurer will see on an application, and for most people with well-controlled asthma it does not push the price of life cover above the standard rate. Life insurance is most often underwritten on your personal circumstances, and premiums are affected by age, health and lifestyle¹. Asthma sits inside that health picture, but it is one factor among several rather than an automatic loading.

What matters is not the word "asthma" on your medical record but how the condition behaves: how often it flares, what treatment you take, whether you have needed hospital care, and how recently. The insurer asks about your health when you apply and you declare any conditions you have at that time². Answer that honestly and the underwriter decides whether your case is standard or needs a loading.

The bigger lever on your premium is usually lifestyle. Smoking, high alcohol consumption and even dangerous sports or motorcycling can push up premiums³, and insurers weight premiums for people who use vapes, gum and patches the same as for those who smoke cigarettes⁴. If you have mild asthma and do not smoke, you are in a very different pricing group from someone with the same asthma who does.

How insurers assess mild asthma

Underwriting is the process of turning your answers into a price. For an individually underwritten policy, the insurer asks questions about your health when you apply and asks you to declare any conditions you have at that time². The standard life insurance quote runs to about ten questions, covering medical history and lifestyle, with some questions reaching back five years and others 12 months⁵. Asthma will fall inside those questions.

The Financial Ombudsman Service, which settles disputes between consumers and insurers, has set out how it expects insurers to treat less serious conditions. Where a condition is minor and resolved quickly, the insurer would be expected to take that into account². That principle is what sits behind standard terms for well-controlled asthma: a condition that is stable, needs only routine treatment and has not caused recent hospital care is not the kind of risk that changes the outcome of a life policy.

Where asthma does attract attention is in the detail. A history of hospital admission, frequent courses of steroids, or symptoms that are not well controlled point to a higher risk, and the insurer may load the premium or ask for more information. The same pattern shows in other conditions: applicants with diabetes are asked for full details of when they were first diagnosed, their medical history and the specifics of their treatment and medication⁹. Asthma underwriting follows the same logic, scaled to how the condition behaves.

What can affect your premium

The premium is built from several inputs, and asthma is only one of them. Policy type and length and level of cover will impact the amount you pay each month, and your age, health and lifestyle can also impact your monthly premium¹⁰. Another insurer puts it the same way: your age, health and lifestyle can impact your monthly premium¹¹. A third lists the full set: your age, your health and lifestyle (including whether you smoke), the type of policy you choose, the length of the term, and the amount of cover¹².

Two of those inputs are worth separating out. The first is the shape of the policy. Decreasing term life insurance carries premiums that are typically less expensive than they are on a level term policy¹³, because the payout falls over time as a mortgage is paid down. The second is how the policy is bought. Joint term life insurance is usually slightly cheaper compared with each partner buying an individual policy, though the price difference is often very small¹⁴.

Then there is the health and lifestyle group, where asthma sits. Any significant pre-existing medical or other health conditions that increase the risk of you dying early will also increase premiums³. Smoking is priced separately and more harshly: insurers weight premiums for people who use vapes, gum and patches the same as for those who smoke cigarettes⁴. If you have mild asthma and use nicotine, the nicotine is likely to move your premium more than the asthma does.

Standard rates are common for well-controlled asthma

Standard terms are the ordinary price, with no loading for your health. For a 53-year-old non-smoker in reasonable health, standard life insurance was quoted at £7 a month for a £10,000 term policy running until you turn 90, as of December 2025⁵. That figure is a market example rather than a promise, but it shows the order of magnitude for straightforward cases.

Cheaper cover exists at younger ages and smaller sums. One provider says policies can be purchased for just £10 per month or even less¹⁵. Another gives an example of £15 a month for single level Plan & Protect life insurance bought online, for ages 26 to 50, where 50% of customers paid these prices or less¹⁶. These are the provider's own figures for its own product, and they are not a quote for your circumstances.

The practical point is that a mild, stable condition does not put you outside the ordinary market. Standard life insurance is priced on your age, your health and your lifestyle⁵, and a well-controlled case is priced within that framework rather than against it. Where the asthma is more active, the insurer may load the premium, ask for a GP report, or postpone cover until the condition settles. That is a decision for the underwriter on the facts of your case, not a rule that applies to everyone with asthma.

Answering the health questions on your application

The application is where the outcome is decided, so it is worth taking slowly. When you apply for an individually underwritten policy, the insurer will ask you questions about your health and ask you to declare any conditions you have at that time². Not every policy works this way: one workplace product says a health questionnaire may be required in some circumstances depending on level of cover, but usually is not required¹⁷. Another is built around minimal underwriting, with just five health questions¹⁸.

Answer the questions as they are put to you, and answer them fully. The periods matter: some questions reach back five years, others 12 months⁵. If a question asks whether you have ever had a condition, that is what it means. If it asks about the past 12 months, that is the window. Do not decide for yourself that an old diagnosis is too minor to mention, and do not leave out a hospital admission because it was years ago.

If you are unsure what your medical record says, you can ask your GP surgery for a summary before you apply. That is also useful if the insurer later asks for a GP report, which is a normal step where the answers need clarifying.

Using a broker or comparing insurers

There are three broad routes to cover, and they differ in how much work falls to you.

• Going direct to an insurer. You answer that insurer's questions and get that insurer's price. Simple, but you see one set of terms.
• A comparison website. Convenient, but the policies you will be offered on a comparison website will be fairly generic, so if you want cover that meets your individual needs it may not be the right route²⁰.
• A broker. You may want to use an insurance broker²¹. A broker can approach several insurers, and if you need to make a claim, your broker might speak to loss adjusters and claims departments and do as much as possible for you²⁰. For a health condition, a specialist life insurance broker such as LifeSearch, which focuses exclusively on this product and has direct contact with underwriters, can put your case to insurers who are comfortable with it⁹.

Cost is not the only difference. A broker may charge a fee, or take commission from the insurer, and that can affect what you are offered. MoneyHelper, the government-backed guidance service, explains when an insurance broker is worth using²⁰. If cost is the concern, the general approach to insurance is to gather details of the deals you have found, call your provider and tell them you are thinking of switching, and ask them to match or beat the other deals²².

If your application is loaded, postponed or declined

A loading means the insurer will cover you but at a higher premium than standard. A postponement means the insurer wants to wait, usually until a condition has been stable for a period, and will look again. A decline means the insurer will not offer cover on the terms applied for. None of these is the end of the road, and each has a different next step.

If you are declined, a broker can approach insurers who take a different view of the same condition. If you are postponed, ask what the insurer is waiting for and when it will reconsider. If you are loaded, you can ask whether the loading is reviewable. Some policies allow the insurer to increase or decrease the premium for existing policies no more than every 5 years under specific circumstances set out in the policy terms⁷. Another allows an increase or decrease no more than every 2 years, to reflect unexpected changes in claims, expenses, lapses, investment income or a change in the law⁸.

It is worth understanding which type of premium you have bought. With reviewable premiums, the insurer has the right to periodically review your premiums and may opt to increase them, based on the insurer's financial position and expectation of paying future claims¹⁴. Family income benefit insurance can be bought with guaranteed premiums, fixed for the whole term, or reviewable premiums, which are lower initially but may be increased on regular review²³. A guaranteed premium will not fall if your asthma improves, but it will not rise either.

If a claim is turned down and you think the decision is wrong, the Financial Ombudsman Service is free and independent. It has published guidance on pre-existing medical conditions and on changes in health, and it can look at how the insurer applied its own questions². The ombudsman's expectation that insurers take minor, quickly resolved conditions into account is the kind of principle it applies when it reviews a case².
