How to cancel O2 UK

A quick, up-to-date guide to cancelling O2 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 O2 UK bills you after you cancel, you have a refund pack ready. Add to Chrome — Free

Cancel O2 UK in 5 steps

  1. Sign in to My O2 at o2.co.uk, or prepare to call O2 (202 from an O2 phone, or 0344 809 0202).
  2. Cancelling an O2 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

O2 UK requires 30 days' notice, so you're billed through the notice period, and early-termination fees may apply within a minimum term. On an O2 Refresh plan, the device and airtime plans are separate — settle the device plan. Keep your cancellation reference.

Subscribed through Apple, Google, or another provider?

O2 UK bills you directly. There's no app-store subscription — cancellation goes through O2 by phone or online.

Charged after cancelling O2 UK?

It happens more than it should. If a charge lands after you cancelled, here's how to get your money back from O2 UK — and why documented proof is what makes the difference.

Frequently asked questions

Will O2 UK charge me after I cancel?
It shouldn't. After you cancel, O2 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 O2 UK.
Does cancelling O2 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 O2 UK's settings.
How do I know my O2 UK cancellation worked?
Look for a cancellation confirmation email from O2 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.
