Two things set the ceiling on a COPD application before anything else is considered: what stage the disease has reached, and whether supplemental oxygen is in use. Everything else moves the file within that ceiling rather than lifting it.
Our COPD and respiratory conditions page covers the assessment in general. This one is about severity specifically — how it is measured, why oxygen is a hard line, and what remains available at each level.
How severity is actually measured
Underwriters do not work from how you describe your breathing. They work from spirometry, and specifically from FEV1 as a percentage of predicted — how much air you can force out in one second, against what someone of your age, sex and height would be expected to manage.
The GOLD staging system divides that into four bands:
- GOLD 1 (mild) — FEV1 at or above 80% of predicted
- GOLD 2 (moderate) — 50% to 79%
- GOLD 3 (severe) — 30% to 49%
- GOLD 4 (very severe) — below 30%
If you do not know your FEV1 percentage, that is the first thing to find out. It is on your spirometry report and it will shape the entire application. Applying without knowing it means applying blind.
The prognostic index underwriters borrow
Carriers do not underwrite from lung function alone, because lung function alone predicts mortality less well than a composite does. The BODE index — body mass, obstruction, dyspnoea, exercise capacity — is the standard composite, scored 0 to 10, and the survival separation across its quartiles is wide:
- Score 0–2 — roughly 80% four-year survival
- Score 3–4 — roughly 67%
- Score 5–6 — roughly 57%
- Score 7–10 — roughly 18%
Those figures come from the original validation study published in the New England Journal of Medicine in 2004, and they explain the shape of COPD underwriting better than any rate chart. A gap between 80% and 18% four-year survival is not something a carrier can price across with a single modest surcharge, which is why outcomes at the two ends of the range are so different.
It also explains why BMI and exercise tolerance carry weight in a lung condition. Both are BODE components. Weight loss and reduced walking distance are prognostic signals in COPD, not incidental facts about you.
Oxygen is the hard line
Supplemental oxygen changes the question from which rate class to which product.
Continuous home oxygen is treated as a marker of advanced disease across the market. Practitioners consistently report that it moves an application out of fully underwritten and accelerated territory entirely, and that it appears as a knockout question on most simplified issue applications alongside confinement and dialysis. Nocturnal-only oxygen is sometimes viewed less severely, but it is still a question you will be asked directly.
Where oxygen is in use, guaranteed issue and final expense products are usually what remains — small face amounts, level premiums, and a graded death benefit for the first two or three years. That is a narrower outcome than most people want, and it is worth knowing before an application is filed rather than after.
Smoking status does more here than anywhere else
Every carrier prices smokers separately, and in a lung condition the interaction compounds: continuing to smoke with diagnosed COPD is read as an unmanaged progressive disease rather than as two separate risk factors added together.
Time since quitting matters and is documented. Most carriers use a 12-month threshold for smoker rates and many look at 24 to 60 months for their better classes. For a COPD applicant, quitting is the only variable on the entire application that can meaningfully move the ceiling, and the effect is not small.
What tends to happen at each level
Carrier manuals are not published, so what follows is the shape practitioners report rather than any carrier’s stated guidance:
- Mild, no medication, non-smoker, normal build. Traditional term cover is generally available, sometimes at or near standard rates. Uncommon, but it happens, and it is worth testing before assuming otherwise.
- Moderate, on an inhaler, stable. Traditional cover with a table rating is the usual outcome. Carrier spread is wide at this level — this is where shopping the file is worth the most.
- Severe, on multiple medications including oral steroids. Fully underwritten offers become scarce. Simplified issue is the realistic route, subject to the knockout questions.
- Very severe, or on oxygen. Guaranteed issue and final expense.
Frequent exacerbations, recent hospital admissions and courses of oral steroids all push a file toward the harder end regardless of the spirometry number, because they show instability rather than a fixed level of impairment.
Prepare these before applying
- Your most recent spirometry report, with the FEV1 percentage of predicted
- Date of diagnosis, and whether staging has changed since
- Full medication list — bronchodilators, inhaled steroids, combination inhalers, oral steroids, roflumilast, theophylline, antibiotics
- Any hospital admissions or exacerbations in the last two years, with dates
- Smoking history: pack-years, and the date you stopped if you have
- Current height and weight
Prescription data is checked against a pharmacy database regardless of what the form says, so an omitted inhaler creates a discrepancy rather than a better outcome. The reasoning is set out on our how underwriting works page.
What to do next
Get your FEV1 percentage of predicted from your most recent spirometry report. That single number tells you which of the four bands above you are in, and therefore which products are realistically open to you.
If you are in the mild or moderate band, apply for traditional cover and expect to shop it across several carriers — the spread on identical COPD files is wide enough to be worth the effort. If oxygen is in use, start at guaranteed issue and size the policy to the actual purpose rather than to a number you would have preferred.
And if you still smoke, that is the one thing on the whole application still within your control.
