How to cancel Three UK

A quick, up-to-date guide to cancelling Three UK — and keeping proof that you did, in case you're charged anyway.

Before you click cancel: the moment you cancel is exactly when proof matters. CancelProof records your cancellation — the pages, the clicks, the confirmation — so if Three UK bills you after you cancel, you have a refund pack ready. Add to Chrome — Free

Cancel Three UK in 5 steps

  1. Sign in to My3 at three.co.uk, or prepare to call Three (333 from a Three phone, or 0333 338 1001).
  2. Cancelling a Three contract is generally done by phone or their online chat/PAC-code flow.
  3. Give the required 30 days' notice; you're billed through the notice period.
  4. If you're within your minimum term, ask about early-termination charges.
  5. If switching networks, request a PAC code to keep your number. Get a cancellation reference.

What happens after you cancel

Three UK requires 30 days' notice, so you're billed through the notice period, and early-termination fees may apply within a minimum term. Request a PAC code if keeping your number. Return any leased equipment. Keep your cancellation reference.

Subscribed through Apple, Google, or another provider?

Three UK bills you directly. There's no app-store subscription — cancellation goes through Three by phone or online.

Charged after cancelling Three UK?

It happens more than it should. If a charge lands after you cancelled, here's how to get your money back from Three UK — and why documented proof is what makes the difference.

Frequently asked questions

Will Three UK charge me after I cancel?
It shouldn't. After you cancel, Three UK keeps your access until the end of the billing period you've already paid for, then stops billing. If a charge still appears, see our guide on being charged after cancelling Three UK.
Does cancelling Three UK delete my account?
No. Cancelling stops future billing but usually keeps your account so you can return later. Deleting your account is a separate action in Three UK's settings.
How do I know my Three UK cancellation worked?
Look for a cancellation confirmation email from Three UK and check that your account shows the plan ending. Keeping that confirmation — an email or a screenshot — is your proof if there's ever a dispute.
