Insurance Curator 
When you apply for life insurance in the UK, the biggest price divide starts with one question: Are you a smoker? It sounds simple, but the answer can double your premiums overnight. Insurers don’t just take your word for it — they want proof. From nicotine tests to GP reports, the evidence you provide shapes the policy you get. Whether you live in London, Manchester, or Edinburgh, understanding what insurers ask for — and why — can save you hundreds of pounds a year.
This guide walks you through the health checks, medical evidence, and documentation you might need. We’ll also show you how to prepare, what to expect, and how to improve your chances of getting a non-smoker rate. Plus, we’ll point you to expert resources like Life Insurance Made Simple to help you navigate the process.
Why Insurers Care So Much About Smoking
Smoking is the single biggest lifestyle factor in life insurance underwriting. Smokers pay two to five times more than non-smokers for the same cover. That’s because smoking increases your risk of heart disease, stroke, lung cancer, and respiratory conditions. Insurers use mortality tables to price risk, and smokers consistently show higher death rates.
The difference isn’t small. A 40-year-old non-smoker in the UK might pay £30 a month for a £200,000 policy. The same person as a smoker could pay £90 or more. Over 25 years, that’s a staggering £18,000 extra.
What Counts as a Smoker? It’s Broader Than You Think
Insurers don’t just ask about cigarettes. They define “smoker” broadly. If you’ve used any nicotine product in the last 12 months, you’re likely classed as a smoker. This includes:
- Cigarettes, cigars, pipes, and shisha
- Vaping or e-cigarettes (even without nicotine)
- Nicotine gum, patches, and lozenges
- Chewing tobacco or snus
We cover this in detail in our guide When Are You Classed as a Smoker for Life Insurance? Vaping, Nicotine Gum, and More?. Also, Vaping vs Cigarettes: How Different Nicotine Habits Are Treated by UK Insurers explains why vaping doesn’t automatically get you non-smoker rates.
Key point: Even occasional or social smokers are charged smoker rates. Insurers rarely offer a “light smoker” category. If you smoke one cigarette a week, you pay the same as someone who smokes a pack a day. Learn more in Occasional and Social Smokers: Why Insurers Often Still Charge Full Smoker Prices.
Health Checks Insurers Might Request
Not every applicant needs a medical exam. For smaller policies (under £250,000) and healthy non-smokers, you may only answer a health questionnaire. But for higher sums or smokers, insurers often require evidence.
1. Nicotine and Cotinine Tests
The most common test is a saliva or urine test for cotinine (a nicotine metabolite). Cotinine stays in your system for up to 7 days after occasional use, and longer for regular smokers. A positive result means smoker rates — even if you’ve quit recently.
2. Blood and Urine Panels
For larger policies (over £500,000), insurers may request a blood test. This checks for:
- Nicotine (cotinine)
- Cholesterol and glucose levels
- Liver and kidney function
- HIV and hepatitis markers
3. GP Report
Insurers can request a report from your NHS GP. This reveals your full medical history – any smoking-related conditions like COPD, high blood pressure, or diabetes. If you’ve told your GP you smoke, that’s on record.
4. Height, Weight, and BMI Measurement
Height and weight are always recorded. High BMI combined with smoking nearly doubles your premiums. Insurers use the two together to assess cardiovascular risk.
5. Blood Pressure Check
Some insurers send a nurse to your home for blood pressure and pulse readings. High readings can lead to loaded premiums or declinature.
Medical Evidence: What You Must Prove
When you apply, you must be honest. Insurers have access to the Medical Underwriting Database (MUD) and MIB (Motor Insurance Bureau) for fraud checks. Withholding smoking status is considered non-disclosure. If you die within two years and the insurer discovers you smoked, they can void the policy and refuse to pay out.
What if You’ve Quit?
If you’ve stopped smoking, you can qualify for non-smoker rates after 12 months (sometimes 24 months for heavy smokers). You’ll need to prove it with a negative cotinine test. Don’t assume your word is enough – insurers always verify.

How Smoking Affects Premiums: Real Numbers
Let’s compare a 35-year-old male in Birmingham applying for a 25-year, £300,000 level term policy:
| Smoker Status | Monthly Premium (approx) | Total over 25 years |
|---|---|---|
| Non-smoker | £28 | £8,400 |
| Smoker | £85 | £25,500 |
| Difference | £57/month | £17,100 extra |
That’s a 200% increase. The exact numbers vary by age, gender, and insurer. Check our full analysis in How Smoking Affects Life Insurance Premiums in the Uk: Real Numbers, Real Examples?.
Regional Differences Across the UK
Insurers don’t discriminate by city, but local health trends can affect your risk profile. In Glasgow, where smoking rates are higher than the national average, underwriters may be stricter with evidence. In London, high demand for large policies often triggers full medical tests. In Manchester and Liverpool, insurers may request GP reports more frequently due to higher rates of respiratory conditions.
Wherever you live, the same rules apply. Your postcode doesn’t change your smoking status, but your local GP records will reflect your habits.
How to Prepare for Underwriting as a Smoker
Want the best possible rates? Here’s your checklist:
- Be upfront about your smoking history. Hiding it wastes everyone’s time.
- Get healthy: exercise, improve diet, lower cholesterol. That can offset some risk.
- Consider a non-smoker medical exam after you’ve quit for 12 months.
- Compare quotes – some insurers are more lenient than others on nicotine use. Use a broker.

Cigars, Pipes, and Shisha: Special Cases
Many people think cigars and pipes are different. They aren’t. Insurers treat any inhaled tobacco product as smoking. Shisha is especially problematic because an hour-long session exposes you to as much nicotine as 10 cigarettes.

Non-smoker Discounts: How Healthy Lifestyles Unlock Better Deals
Once you’re nicotine-free for 12 months, you can access non-smoker discounts. Some insurers also reward healthy habits like regular exercise, low cholesterol, and normal blood pressure. These are called health-rated or preferred non-smoker policies. They can shave off up to 10% more. We cover this in Non-smoker Life Insurance Discounts: How Healthy Lifestyles Unlock Better Deals.
The Takeaway
Insurers ask for health checks and medical evidence to prove your smoking status because it’s the single biggest factor in your premium. Whether you’re a daily smoker in Cardiff or a social vaper in Leeds, the rules are the same. Be honest, prepare for tests, and if you’ve quit, use that to your advantage.
