KEY ANSWER

The position in brief

People convicted or cautioned for certain sexual offences must notify the police of their details under Part 2 of the Sexual Offences Act 2003, often called the sex offenders register. The period is set by the sentence, not chosen by the judge: indefinite for 30 months' custody or more; 10 years for more than 6 and under 30 months; 7 years for 6 months or less or a hospital order; 5 years for other sentences such as a community order; the length of the discharge for a conditional discharge; and 2 years for a caution. Fixed periods are halved for under 18s. Indefinite requirements can be reviewed after 15 years (8 years for those under 18 when convicted).

Legal issues

What must be notified

Name, address, date of birth and national insurance number within 3 days of conviction or release, and then any changes within 3 days. Also foreign travel, staying at other addresses, bank and card details, passports, and living in a household with a child, in the circumstances set by the regulations. Notification is renewed at least once a year, or weekly for those with no fixed address.

Breach

Failing to comply without reasonable excuse, or giving false information, is an offence with a maximum of 5 years' imprisonment.

Review of indefinite requirements

An application goes first to the police, then can be appealed to the magistrates' court. The question is whether you continue to pose a risk of sexual harm.

Changes coming

The Crime and Policing Act 2026 will add further duties once brought into force, including giving at least 7 days' notice before using a new name, notice before being away from home for 5 days or more, and notice before entering private places where children are likely to be present. These are not yet in force.

Evidence that matters

A review application succeeds on evidence: compliance, treatment and offending-behaviour work, stable circumstances and risk assessments.

Reasonable lines of enquiry

Before sentence

  • Check the exact sentence length: it decides the notification period.
  • Check whether the offence is one that triggers notification at all, and any thresholds in Schedule 3.

What happens next

The court confirms the requirement at sentence, and the police manage it afterwards, often with home visits. A sexual harm prevention order can be made alongside it.

Immediate steps

  • Make the first notification within 3 days.
  • Keep a record of every notification.
  • Ask before travelling abroad.

What should you send us?

Send the sentence details, the notification start date and any police correspondence.

FREQUENTLY ASKED QUESTIONS

Questions before your next step

Can the judge decide not to put me on the register?

No. It follows automatically from the offence and sentence where the conditions in the Act are met.

Will my employer find out?

The requirement is not published, but convictions may appear on DBS checks and some employers must be told.

Can I come off the register early?

Fixed periods end automatically. Indefinite requirements can be reviewed after 15 years (8 for those convicted under 18).
