In the UK, the frequency of smear tests (cervical screening) depends on age and risk factors. From age 25 to 64, people with a cervix are invited for cervical screening every 5 years as of recent changes implemented in 2025. Previously, invitations were every 3 years for ages 25 to 49, but improvements in HPV testing allow for extending the interval to 5 years for those who test negative for HPV and have no recent history of the virus. Those aged 50 to 64 have long been invited every 5 years. People at higher risk or with positive HPV test results may be invited more often. Screening is not usually offered under age 25 or over 64 if there have been normal previous results.

Summary of current UK smear test intervals:

• Ages 25 to 64: Every 5 years if HPV-negative (routine screening).
• Ages 25 to 49: Used to be every 3 years, now 5 years if HPV-negative (England from July 2025).
• Ages 50 to 64: Every 5 years.
• More frequent screening for those with HPV or abnormal results.
• No routine screening under age 25 or over 64 with normal screening history.

This change reflects advances in HPV testing, which better identifies risk and allows safer, less frequent screening to reduce unnecessary procedures while maintaining cancer prevention.
