When you take out a new private health insurance policy in the UK, you may not be covered for everything straight away. Most insurers apply a “waiting period” — a set time you must be insured before certain benefits become available. In this 2025 guide, we explain what waiting periods are, how long they usually last, why insurers use them, and how to reduce or avoid delays so you can access care faster.
Quick facts:
- Waiting periods protect insurers from people only joining when they’re about to claim.
- They vary by policy type — from 0 days for emergencies to 24 months for pre-existing conditions.
- You can sometimes avoid them if you transfer from another insurer with continuous cover.
- Knowing the rules can save you months of waiting.

What Is a Waiting Period in Health Insurance?
A waiting period is the time between your policy starting and when you can claim for certain treatments. While most policies cover accidents and emergencies immediately, many have waiting periods for:
- Pre-existing medical conditions
- Maternity benefits
- Specialist therapies like physiotherapy or counselling
- Chronic condition management
Example:
If your policy has a 6-month waiting period for physiotherapy, you can’t claim for it until 6 months after your cover starts.
Why Do Insurers Use Waiting Periods?
Waiting periods help insurers prevent “adverse selection” — where people only take out cover when they know they’ll need expensive treatment. Without them, premiums would rise sharply for everyone.
They also give insurers time to verify medical history and reduce the risk of immediate, high-cost claims from new members.
Typical Waiting Periods in the UK (2025)
| Benefit Type | Typical Waiting Period | Notes |
|---|---|---|
| Emergency treatment | 0 days | Immediate cover from policy start |
| General consultations & outpatient care | 0–14 days | Some insurers require a short activation time |
| Maternity benefits | 10–24 months | Applies to pregnancy & childbirth cover |
| Dental & optical cover | 3–6 months | Common with add-on cover options |
| Pre-existing conditions | Up to 24 months | Dependent on insurer’s underwriting |
How Waiting Periods Affect Pre-Existing Conditions
If you have a pre-existing condition, most insurers won’t cover it immediately. You’ll either have:
- Moratorium underwriting — the condition is excluded for a set period (e.g., 2 years) unless you remain symptom- and treatment-free.
- Full medical underwriting — the insurer reviews your full medical history before setting terms.
Some providers, like Bupa or AXA Health, offer “continued personal medical exclusions” which may allow you to keep your existing terms when switching policies, avoiding a fresh waiting period.
Can You Avoid Health Insurance Waiting Periods?
Yes — in some cases. You may be able to skip or reduce waiting periods if:
- You switch insurers without a break in cover.
- Your employer offers group health insurance with no waiting periods.
- The insurer is running a promotional offer (common in January & September).
Always ask for a ‘no waiting period guarantee’ in writing before buying.
Tips to Minimise or Skip Waiting Periods
- Buy health insurance while you’re healthy — before you need treatment.
- Consider family or corporate cover — these often have shorter or no waiting periods.
- Switch providers strategically — time it so your cover overlaps and you maintain continuous insurance.

FAQs
Do all health insurance policies have waiting periods?
No — some have no waiting period for certain treatments, but almost all apply them to maternity and pre-existing conditions.
Can I claim during the waiting period?
Only for treatments that are covered immediately, like emergencies or included routine check-ups.
Will my waiting period restart if I change my plan?
Possibly — if you upgrade or add new benefits, the waiting period for those benefits may start from the date of the upgrade.
