In UK health Insurance, a Pre-Existing Conditions refers to any illness, injury, or medical issue you had before your policy began.
Common examples include:
- Diabetes
- High blood pressure
- Asthma
- Chronic back pain
- Depression or anxiety
Insurance providers use this information to decide what cover they can offer, how much it will cost, and whether certain conditions will be excluded.
How UK Insurers Handle Pre-Existing Conditions
When applying for health Insurance, insurers typically take one of these approaches:
1. Complete Exclusion
They’ll insure you for everything except the pre-existing condition.

2. Moratorium Cover
The insurer won’t cover your condition for a set period (usually 2 years). If you remain symptom-free, coverage may begin after that time.
3. Full Medical Underwriting
They review your entire medical history and decide case-by-case which conditions to include or exclude.
