Applying for life insurance with a pre‑existing condition can feel daunting. You worry about being declined, faced with high premiums, or tangled in paperwork. Yet the key to a smooth application is preparation – and that starts with understanding medical underwriting.
Medical underwriting is how insurers assess your health risks. They review your medical history, lifestyle, and family background to set your premium. The process relies heavily on documents, GP reports, and your honest answers. Get these right, and you stand the best chance of affordable cover.
Let’s break down exactly what you need to prepare, what to expect from your GP, and why transparency is your strongest ally.
What Is Medical Underwriting?
Medical underwriting is the insurer’s way of evaluating the likelihood that you’ll make a claim. For standard applicants, it’s often a short health questionnaire. For someone with a pre‑existing condition – diabetes, asthma, high blood pressure, or even a past cancer diagnosis – the process goes deeper.
Insurers want to see:
- The type and severity of your condition
- How well it’s managed
- Any complications or related treatments
- Your current medication and consistency of care
Understanding this upfront helps you gather the right information.
Why Honest Answers Are Non‑Negotiable
The temptation to downplay a symptom or omit a test result can be strong. But honesty isn’t just ethical – it’s essential for valid cover.
If you fail to disclose a condition and later make a claim, your insurer can void the policy. That leaves your family with nothing. The UK insurance industry relies on the principle of utmost good faith – both parties must be truthful.
Even if a condition feels minor (like mildly raised cholesterol), mention it. Insurers see thousands of cases daily; they expect honesty. As the title suggests, “honest answers” are your best tool.
Essential Documents You’ll Need
Before you apply, gather these key documents:
- Your current medication list: Names, dosages, frequency, and prescribing doctor.
- Any hospital discharge summaries or specialist reports related to your condition.
- Recent test results: Blood pressure readings, HbA1c (for diabetes), cholesterol levels, etc.
- Your NHS health summary or private medical records – your GP can provide these.
- Details of any previous surgeries or hospital admissions.
Having these ready speeds up the process and shows the insurer you’re well‑organised.
Understanding Your GP Report
Most insurers will request a GP report – a detailed summary from your doctor. This can take a few weeks, so plan ahead. The report typically includes:
- Your full medical history (chronic conditions, prescriptions, appointments)
- Any lifestyle notes (smoking, alcohol use, BMI)
- Referrals to specialists or hospital visits
What if your GP record has an error or an outdated diagnosis? You can request to see your medical records before the report is sent. Correcting any inaccuracies now prevents surprises later.
For example, an old note of “possible asthma” when you’ve never been diagnosed could increase your premium. Talk to your GP about clearing up ambiguous entries.
The Role of a Specialist Broker
If you have a complex medical history, consider using a specialist broker. They know which insurers are most lenient for your specific condition. They also help you frame your application in the best possible light without misrepresenting anything.

Step‑by‑Step Guide to Preparing Your Application
1. Review your medical records – request a copy from your GP and check for errors.
2. Gather recent test results – if you don’t have them, ask your GP practice.
3. Make a list of all medications – include over‑the‑counter and supplements.
4. Note any lifestyle changes – if you quit smoking or lost weight, mention that.
5. Write a timeline of your condition – when diagnosed, treatments, current status.
6. Contact a specialist broker – they’ll advise on which insurer to approach.
7. Complete the application thoroughly – don’t leave blank spaces.
8. Authorise the GP report – be aware that delays here are common.
Following these steps reduces the chance of being asked for more information later.
Common Questions Insurers Ask
During medical underwriting, you’ll be asked about:
- Family history – especially heart disease, stroke, cancer, or diabetes in parents or siblings.
- Your own health – any ongoing conditions, hospitalisations, or mental health treatment.
- Lifestyle – smoking, vaping, alcohol consumption, exercise, and occupation.
- Travel plans – if you intend to live or work abroad, that may affect cover.
Be ready with specific dates, dosages, and names of specialists. Vague answers can trigger further enquiries.

What If You’ve Been Declined?
A decline isn’t the end of the road. Some conditions are simply not accepted by mainstream insurers, but specialist providers exist. Also, your health may improve – for example, after cancer treatment, there’s often a waiting period before cover becomes available.
