Critical illness cover can respond to COPD only when the disease reaches the stage a lung definition describes. Legal & General, Aviva and Royal London call it respiratory failure or chronic lung disease, and test it by oxygen use and lung function results, not by a COPD diagnosis alone.

Living with COPD and weighing up an application? An FCA-authorised broker can unpick how insurers phrase the lung definition and what they will ask you. The form on this page wants a first name, age range, who needs cover and a phone number, nothing medical, and the broker's call is free.

What do insurers call the lung condition they cover?

Three insurers, three names. Legal & General's Guide to Critical Illnesses Covered (QGI14860 01/26) lists respiratory failure of advanced stage. Aviva's Life Insurance+ Policy Conditions (AL50002 02/2026) has respiratory failure of specified severity. Royal London's Personal Menu Plan critical illness plan details (July 2025) call theirs chronic lung disease of specified severity, and the LV= policy summary (49027-2022 04/26) lists severe lung disease. Legal & General notes that some insurers use those other names for respiratory failure, so the name on a list is a poor guide to the test behind it.

No policy has to carry any of them. The Association of British Insurers (ABI) names only cancer, heart attack and stroke as conditions every critical illness policy must cover, so a lung definition belongs to an individual policy's list. Read that list first. The conditions critical illness cover names shows how lists compare, and the ABI minimum standards are explained separately.

What tests does the lung wording set?

Legal & General's definition is the plainest to follow, and every limb must be met together:

Advanced stage emphysema or other chronic lung disease, resulting in all of the following: The need for regular oxygen treatment on a permanent basis, and The permanent impairment of lung function tests as follows: Forced Vital Capacity (FVC) and Forced Expiratory Volume at 1 second (FEV1) being less than 50% of normal

The other two have the same shape with different words:

Insurer and documentOxygen limbLung function limbs
Legal & General, QGI14860 01/26Regular oxygen treatment on a permanent basisFVC and FEV1 each under 50% of normal
Aviva, AL50002 02/2026"daily oxygen therapy for a minimum of 15 hours per day for at least six months"FEV1 and FVC each below 50% of normal
Royal London, plan details July 2025Continuous daily oxygen therapy on a permanent basisFEV1 under 50% of normal, and vital capacity under 50% of normal

Aviva and Royal London both begin with confirmation by a consultant physician. The percentages match; the oxygen limb does not: Aviva counts hours and months, while Legal & General asks for regular oxygen and Royal London for continuous daily oxygen, both on a permanent basis. FEV1 and what the numbers mean in practice are covered in the guide to life insurance with COPD.

Where do emphysema, chronic bronchitis and a lung transplant fit?

The NHS describes COPD as the name for a group of lung conditions that cause breathing difficulties, including emphysema and chronic bronchitis (page last reviewed 11 April 2023). It adds that "the damage to the lungs caused by COPD is permanent, but treatment can help slow down the progression of the condition". A diagnosis names a long-term condition; the insurer's wording asks how far it has gone.

Legal & General's plain-English note under its definition says it covers advanced lung failure, where breathing is severely affected and regular oxygen therapy is required.

A lung transplant is a separate definition. The ABI's model wording covers receiving a transplant of a complete heart, kidney, liver, lung or pancreas, or inclusion on an official UK waiting list for one, though insurers need not include it, and those that do print their own versions. Where your own test results sit against these thresholds is a question a broker can take up when they ring you.

How do exclusions and extra premiums work for an applicant with COPD?

Legal & General's page on pre-existing conditions (dated 16 March 2026) lists asthma and breathing problems among its examples. It says that some pre-existing conditions "would mean we would be unable to offer Critical Illness, where others may mean we charge an extra premium or exclude the specific condition from the cover", and that every applicant is assessed individually.

An extra premium changes what you pay; an exclusion changes what the policy covers. If you already have COPD, an exclusion is the term to look for, since it leaves that condition out of the cover, and Legal & General's policy terms (QGI13939 2026/10) point to the policy schedule for what is and is not covered.

The same page says an insurer may ask for the date of diagnosis, hospital admissions, how severe and regular your symptoms are, and your medication, and sometimes a medical report from your doctor, which needs your consent. To see how that might read for you before applying, the broker can go through your lung history during their call, which you set up with the form on this page.

If cover is declined or restricted, read critical illness cover with pre-existing conditions, life insurance with medical conditions and the steps after a decline.

What does the disclosure law expect when you answer lung questions?

The Consumer Insurance (Disclosure and Representations) Act 2012 says it is "the duty of the consumer to take reasonable care not to make a misrepresentation to the insurer". Whether you took reasonable care depends on the circumstances, including how clear and specific the insurer's questions were (section 3). The Financial Ombudsman Service adds that "if you are unsure of the answer to a question, it's reasonable to expect you to find out the answer".

Get an answer wrong and Schedule 1 sets the insurer's response by whether the mistake was careless, deliberate or reckless; it ranges from changing the terms or scaling down a claim to refusing every claim.

The disclosure rules for life insurance and when an insurer can refuse to pay set it out in full. Before you answer an application, a broker can go over your own lung history on the phone; the form on this page asks nothing about your health.

Frequently asked questions

Is COPD a critical illness?

Not as a diagnosis. COPD leads to a claim only if it meets a lung definition on your policy's list, which the Legal & General, Aviva and Royal London wordings test by oxygen use and lung function.

Does critical illness cover emphysema?

Legal & General's definition refers to "advanced stage emphysema or other chronic lung disease", with the oxygen and lung function limbs that go with it; earlier-stage emphysema is not what that wording describes.

Does Aviva's 15-hour oxygen rule apply under every policy?

Of the three wordings in the table, only Aviva's counts hours. Legal & General asks for regular oxygen treatment and Royal London for continuous daily oxygen therapy, each on a permanent basis. If you use oxygen overnight or for part of the day, the broker can explain on their free call-back how each wording might treat that.

Does any policy pay for lung surgery?

Some list it. Aviva's Life Insurance+ conditions cover pneumonectomy, removal of an entire lung due to disease or traumatic injury, within upgraded critical illness benefit, chosen at extra cost; removal of one or more lobes is a separate upgraded additional benefit, paying the lower of £30,000 or the cover amount. LV='s policy summary lists pneumonectomy as a full payment condition.
