Private medical insurance in the UK can provide faster access to consultants, treatment choice, and private hospital stays — but only if the policy actually covers what you need when you need it. Pre-existing condition exclusions, moratorium clauses, and underwriting practices vary significantly between insurers. Reading the policy exclusions carefully — and asking specific questions about conditions you're concerned about — is essential before you pay your first premium.
What is a Policy Exclusions?
A UK private medical insurance policy is a contract under which the insurer agrees to pay for eligible private medical treatment in exchange for regular premiums. The policy schedule specifies what is covered (e.g., in-patient, day-patient, out-patient, cancer cover, mental health cover, physiotherapy) and the exclusions. Two main underwriting approaches exist: moratorium underwriting (automatically excludes conditions you had symptoms of in the 5 years before cover started) and full medical underwriting (you disclose all conditions upfront and receive a fixed decision on each).
Red flags to watch for
Under moratorium underwriting, any condition for which you had symptoms, treatment, or medication in the 5 years before starting the policy is excluded for the first 2 years of cover. If the definition of 'symptom' is broad (e.g., 'including anything you saw your GP about'), it can exclude conditions you consider unrelated.
Cancer cover is one of the primary reasons people take out PMI. Some budget policies exclude cancer treatment entirely or limit it to a fixed period (e.g., 2 years of treatment). Confirm whether the policy covers cancer drugs not available on the NHS, ongoing treatment, and palliative care.
Mental health cover is routinely restricted. Check whether the policy covers therapy sessions, psychiatric in-patient treatment, and eating disorder treatment — and what limits apply (number of sessions, days of admission).
Many policies are tiered by hospital network. A budget policy may only cover NHS waiting rooms at a private wing, not a full private hospital. Check whether consultants and facilities you'd actually want to use are in your policy's approved hospital list.
Policies with steep no-claims discounts mean that making any claim significantly increases your future premiums — sometimes by more than the benefit received. This can deter you from using cover you're paying for.
Your legal rights
PMI policies are regulated by the Financial Conduct Authority (FCA) under the Financial Services and Markets Act 2000. Insurers must treat customers fairly under the FCA's Consumer Duty rules (effective 2023). Under the Consumer Insurance (Disclosure and Representations) Act 2012, you must take reasonable care not to make misrepresentations when applying — but insurers cannot void policies for innocent non-disclosure. If your claim is refused, you can complain to the insurer and escalate to the Financial Ombudsman Service (FOS) free of charge. The FOS has jurisdiction over disputes up to £375,000 and around 50% of insurance decisions are overturned in consumers' favour.
Questions to ask before you sign
- 1Does the policy use moratorium or full medical underwriting, and what conditions will be excluded under that approach?
- 2What cancer cover is included — does it cover drugs not available on the NHS and ongoing treatment beyond 2 years?
- 3What mental health cover is included, including therapy, psychiatric inpatient stays, and eating disorder treatment?
- 4Which hospitals and consultants are covered under this policy's hospital list?
- 5How does the no-claims discount structure work — how much will my premium increase if I make a claim?
