Is Phone Sex Legal in the UK?

Guides · Updated 8 November 2026

Yes. Adult phone chat between consenting adults is legal in the UK. Lines on 09 premium rate numbers are regulated by Ofcom, callers must be 18 or over and have the bill payer’s permission, and the price must be made clear before you are charged.

Who regulates phone sex lines?

Paid adult lines in the UK run on 09 premium rate numbers, and premium rate services are regulated by Ofcom. The companies running them must follow a code of practice covering pricing, age checks and how calls are handled.

The rules every line has to follow

What is never allowed

Some things are off limits on every line, whatever the price or theme. Nothing involving anyone under 18, nothing involving real, identifiable people, and nothing that isn’t between consenting adults. Operators end calls that head in those directions.

Is it legal to run a phone sex line?

Yes, provided the operator follows the rules for premium rate services. Most lines are run by established UK companies that handle the numbers, billing and compliance, with operators working from home.

What if something goes wrong?

If you think you’ve been overcharged or misled, contact the service’s helpline first. If that doesn’t sort it out, your phone company and Ofcom are the next steps.
