Health Insurance with Pre-Existing Conditions UK

Can you get private health insurance with pre-existing conditions?

Yes, it is possible to get private health insurance in the UK even if you have pre-existing medical conditions, although the terms and cost of your policy will be affected. Insurers take different approaches to existing health issues, so what one provider declines outright, another may cover with specific terms.

A pre-existing condition is any illness, injury, or medical issue for which you have received treatment, advice, or experienced symptoms in a defined period before the policy start date. Common examples include asthma, diabetes, high blood pressure, depression, and back pain. Insurers typically look at the five years preceding your application, although this varies between providers.

The key to finding suitable cover is understanding the different underwriting methods available, being completely honest in your application, and comparing multiple providers. Working with a specialist broker can make a significant difference to the outcome.

Underwriting methods explained

Private health insurers in the UK use three main underwriting approaches, each handling pre-existing conditions differently:

• Full medical underwriting (FMU): You complete a detailed health questionnaire at application. The insurer reviews your medical history and tells you upfront which conditions are excluded, covered with a loading, or fully covered
• Moratorium underwriting: No health questions asked at the start. Instead, any condition treated in the five years before the policy start date is excluded. If you go two consecutive years without treatment or symptoms, it becomes covered
• Medical history disregarded (MHD): All pre-existing conditions covered from day one with no health questions. Typically only available to employer group schemes of a certain size

For individuals with known pre-existing conditions, full medical underwriting is usually the better choice. The moratorium approach avoids upfront questions but can lead to surprises at claim time when you discover a condition is excluded.

Common exclusions and how they work

When an insurer excludes a pre-existing condition, they will not pay for any treatment related to that condition. The exclusion is usually permanent for the life of the policy, although some insurers review exclusions after a period of years if the condition has resolved.

Typical conditions attracting exclusions include chronic conditions like diabetes and asthma, mental health conditions such as depression and anxiety, musculoskeletal problems including back and joint pain, and heart conditions. Exclusions can be broader than expected — an exclusion for back pain might extend to any spinal condition.

Disclosure obligations

When applying for private health insurance, you have a legal duty to disclose all relevant medical information honestly. Under the Consumer Insurance (Disclosure and Representations) Act 2012, you must take reasonable care not to make misrepresentations to the insurer.

In practice, this means answering every question truthfully and completely. Do not assume a condition is too minor to mention. Common mistakes include forgetting GP consultations, omitting conditions you consider resolved, and not declaring mental health treatment.

How pre-existing conditions affect premiums

If an insurer agrees to cover a pre-existing condition rather than exclude it, they will typically charge a higher premium. For well-managed conditions like controlled blood pressure or mild asthma, the increase might be 10–30% above standard rates. For complex conditions such as cancer history or heart disease, the loading can be significantly higher.

Premiums for private health insurance in the UK typically range from £50 to £200 per month for individuals, depending on age, location, and level of cover. Pre-existing condition loadings sit on top of this base cost.

Tips for getting the best deal

• Use a specialist broker: Brokers know which providers are more sympathetic to specific conditions
• Consider a higher excess: A voluntary excess of £250 to £500 per claim year can reduce premiums by 20–40%
• Choose a six-week option: Policies that only cover conditions with NHS wait times over six weeks are significantly cheaper
• Review cover annually: If your condition improves, you may be able to switch to better terms

Alternatives if cover is unavailable

Health cash plans pay fixed amounts towards everyday health costs like dental, optical, and physiotherapy regardless of medical history, typically costing £10–£30 per month. Self-funding private treatment for specific issues while relying on the NHS for your pre-existing condition is another pragmatic approach.

Some people combine a limited private policy excluding their main condition with NHS care for the excluded condition. This hybrid approach provides faster access for new conditions while relying on the NHS for ongoing management.
