What Does Private Health Insurance Cover in the UK?
Private health insurance can help pay for eligible treatment of acute conditions, giving you access to private hospitals, specialists and diagnostics.

Important policy details to compare
Inpatient and outpatient limits
Some policies provide comprehensive outpatient cover, while others apply monetary or appointment limits. Compare the benefits you are most likely to use.
Hospital and consultant choice
Check which hospitals, specialists and treatment facilities are available locally under each policy.
Cancer and mental health benefits
Cancer and mental health cover can differ significantly between policies. Review the treatment, drug and session limits.
Underwriting and exclusions
Insurers may assess previous medical history differently. A broker can explain how underwriting and exclusions may affect your cover.
Excess and contribution options
The excess is the amount you agree to pay towards eligible treatment. Compare both the premium and what you may need to pay when claiming.
