Understanding the Two Types
Most UK insurers offer critical illness cover at two levels. Core plans (sometimes called “essential” or “basic”) cover a smaller number of conditions – typically the most common and severe. Comprehensive plans cover a much wider range, often including less common conditions, partial payouts for less severe diagnoses, and children’s cover.
| Feature | Core Plan | Comprehensive Plan |
|---|---|---|
| Conditions covered | ~15–25 | ~40–60+ |
| Cost | Lower | Higher (typically 30–50% more) |
| Children’s cover | Usually not included | Often included free |
| Partial payouts | Rarely included | Usually included for less severe conditions |
| Severity definitions | Stricter | Broader, more generous |
What Do Core Plans Cover?
Core plans focus on the conditions that make up the vast majority of claims. The “big three” – cancer, heart attack, and stroke – account for around 85% of all critical illness claims in the UK. Core plans always include these, plus a selection of other serious conditions such as:
- Multiple sclerosis
- Kidney failure
- Major organ transplant
- Permanent disability from accident
- Parkinson’s disease
- Motor neurone disease
Because these conditions make up such a large proportion of claims, a core plan still provides meaningful protection for most people.
What Do Comprehensive Plans Add?
Comprehensive plans include everything in the core plan plus a significantly wider range of conditions. The additional cover typically includes:
- Less severe conditions with partial payouts – Early-stage cancers, less severe heart conditions, or smaller strokes that may not meet the full claim criteria of a core plan. These often pay 10–25% of the sum assured.
- Children’s critical illness cover – Free cover for your children for a range of serious conditions, typically paying 25–50% of your sum assured without affecting your own cover.
- Broader condition definitions – More generous diagnostic criteria that increase the likelihood of a successful claim.
- Additional conditions – Conditions such as loss of hearing, loss of speech, blindness, severe burns, and others that core plans may exclude.
Which Should You Choose?
Choose Core If:
- Budget is your primary concern and you want the most affordable cover
- You mainly want protection against the most common and severe conditions
- You already have income protection in place for ongoing financial support
- You have no dependent children
Choose Comprehensive If:
- You want the broadest possible protection with the highest chance of a successful claim
- You have children who would benefit from the included children’s cover
- You want partial payouts for less severe conditions like early-stage cancers
- You have a family history of conditions that may not appear on core plans
The Claims Reality
According to industry data, the overwhelming majority of critical illness claims are for cancer, heart attack, and stroke. Both core and comprehensive plans cover these. However, comprehensive plans often define these conditions more broadly, covering earlier stages and less severe presentations that core plans might exclude.
For example, a comprehensive plan may pay out for a “less advanced” cancer (such as early-stage prostate cancer) at a partial payout level, whereas a core plan might not cover it at all because it does not meet the full severity threshold.
