Moratorium cover excludes conditions from (typically) the last 5 years, then re-covers each one only after 2 trouble-free years on the policy. Claims fail when people forget that symptoms count without a diagnosis, that related conditions chain together, and that any treatment, medication or advice during the two years resets the clock.
- ✓Symptoms count, not just diagnoses — a GP visit for a sore knee starts the exclusion.
- ✓Related conditions chain: one excluded condition can pull new claims into its orbit.
- ✓Two years clears a condition only if it was genuinely trouble-free — any care resets it.
A 60-second refresher on the rules
Under a typical moratorium, the insurer doesn't ask about your medical history when you join. Instead, anything you had symptoms, treatment, medication or advice for in the last five years is automatically excluded. Each excluded condition becomes covered again once you've gone two continuous years on the policy without symptoms, treatment, medication or advice for it. (Wordings vary — the 5-year/2-year pattern is the common shape.)
It's a genuinely reasonable system: you get cover in minutes without a medical questionnaire, and the insurer protects itself against people buying cover for problems they already have. The failure patterns below aren't the insurer breaking the deal — they're people misreading what the deal was, usually because nobody walked them through it at the point of sale.
Failure pattern 1: 'I was never diagnosed'
The moratorium clock runs from symptoms, not diagnosis. Here's how it plays out for an illustrative 42-year-old: she saw her GP twice about knee pain in 2023, was told to rest it, and never got a diagnosis. She buys moratorium cover in 2026, the knee worsens, and she claims for investigation. The claim is declined — the 2023 GP visits mean the knee is a pre-existing condition, diagnosis or no diagnosis.
Failure patterns 2 and 3: chains and reset clocks
The second pattern is the related-condition chain. Insurers exclude not just the pre-existing condition but conditions medically related to it. An illustrative example: a man with pre-existing high blood pressure claims for an unrelated-seeming heart investigation two years later. Because the cardiology issue is judged related to the hypertension, it falls under the same exclusion. Where the boundary of 'related' sits is a medical judgement made at claim time — which is precisely why it surprises people.
The third pattern is assuming two years on the policy clears everything automatically. It doesn't. The two years must be trouble-free for that specific condition. One repeat prescription, one check-up, one GP conversation about it during those two years and the clock resets to zero.
| What people assume | What the moratorium actually says |
|---|---|
| Only diagnosed conditions are excluded | Symptoms, treatment, medication or advice all count |
| Exclusions cover one named condition | They extend to medically related conditions |
| After 2 years everything is covered | Each condition needs 2 trouble-free years — any care resets it |
| The insurer decides cover when you join | Eligibility is assessed at claim time, from your medical records |

How to buy moratorium cover safely
- Audit your own last five years. Before buying, list every GP visit, referral, prescription and symptom you can remember. That list, not your self-image as a healthy person, is what the insurer will see in your records at claim time.
- Assume anything on the list is excluded for now. If a likely claim area is on it, moratorium may be the wrong tool — full medical underwriting gets you certainty in writing instead, and sometimes covers things a moratorium wouldn't.
- Don't manage conditions strategically. Skipping GP visits to keep a two-year clock running is a bad trade: you're risking your health to win an insurance technicality, and untreated symptoms still count if they're in your records later.
- Keep your own timeline. If a claim is ever questioned, a clear record of when symptoms genuinely started is your best evidence.
Frequently asked questions
What are the most common ways moratorium cover goes wrong?
Three patterns dominate: claiming for something you had symptoms of before joining (diagnosis isn't required for exclusion), being caught by related-condition chains, and assuming two years on the policy automatically clears exclusions when any treatment or advice during those years resets the clock.
Can a moratorium claim be declined if I was never diagnosed?
Yes. Moratorium exclusions run from symptoms, treatment, medication or advice — not diagnosis. If you saw a GP about knee pain in the look-back period, the knee is pre-existing even though nobody named a condition. This is the single most common moratorium surprise.
Does two years on a moratorium policy clear all my exclusions?
Only condition by condition, and only if each was genuinely trouble-free. Two continuous years without symptoms, treatment, medication or advice for a condition re-covers that condition. A single prescription or check-up for it during those two years resets its clock to zero.
What are related-condition chains in moratorium underwriting?
Insurers exclude conditions medically related to a pre-existing one, not just the named condition. A claim for a heart investigation could fall under a hypertension exclusion, for example. The relatedness judgement is made at claim time, which is why it catches people out.
How do I buy moratorium cover safely?
Audit your last five years of GP visits, prescriptions and symptoms before buying, assume everything on that list is excluded for now, and consider full medical underwriting if a likely claim area appears on it. Never skip medical care to protect a two-year clock.
