How to cancel Three
What its contract says about leaving.
We read the Three terms on 12 April 2026. The company may have changed them since, and your contract may be different.
Notice and dates for leaving
- Minimum term end date
- Typically 24 months from activation (Three must send you an end-of-contract notification)
What the contract says about leaving
- Early termination chargesLeaving before the end of your minimum term means paying all remaining monthly charges. On a 24-month handset contract, this can easily exceed several hundred pounds.
- Roaming charges outside inclusive destinationsThree's Go Roam destinations include many European and worldwide locations, but data use abroad is subject to a fair-use limit. Exceeding it or roaming in non-inclusive countries incurs high charges.
This page does not explain how Three handles cancelling (by phone, on its website or with a form). For that, see the company's own page.
This is not legal advice. It is a summary, made with the help of AI, of the terms the company publishes.
