Cancel by reason

Cooling-off (change of mind)

Rule: You have 14 days to cancel distance or off-premises contracts for most purchases, and 30 days for Home Broadband and Business Broadband. Required proof: order confirmation, receipt or cancellation form. Applicable law: The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. See legislation.gov.uk.

Price increase

Rule: If Three increases the monthly charge during your contract and you do not accept the new price, you may have the right to end the contract without penalty if the contract terms allow exit for price rises. Required proof: written notice from Three showing the price change. Applicable law: Consumer Rights Act 2015 for unfair terms and the contract terms; escalate to Citizens Advice for guidance.

Moving address

Rule: Moving home is not automatically a statutory right to end a broadband contract unless the provider cannot supply the service at the new address. Required proof: new address evidence such as tenancy agreement or utility bill. If service cannot be provided at the new address, Three may permit termination under its policies; confirm with customer services.

Death of subscriber

Rule: Death of the account holder may be accepted as grounds to end the contract. Required proof: death certificate and proof of identity of the requester. Contact Three Customer Services and provide documents; Three will advise next steps.

Legitimate grounds accepted by 3 WiFi

Based on Three guidance, accepted grounds include returning within cooling-off periods, inability to provide service at new address, and death of subscriber. Required proof varies by ground and must be submitted to Three Customer Services.

End of commitment

Rule: At the end of your minimum commitment term (for example 24 months), you can let the contract expire or cancel with any required notice. Required proof: confirmation of contract end date from your account. Applicable law: Contract terms and Consumer Rights Act 2015 if the contract contains unfair terms.

Negotiate or save

Before you cancel: negotiate

How to ask for retention offers: Call Three on 333 (from a Three mobile) or 0333 3381001 (from another phone). Tell the advisor you are considering cancelling and request any available retention offers, discounts or a contract change to a cheaper plan. Research did not publish specific retention offers by name; Three historically uses discounts and plan changes when customers call. If you call, ask for a written confirmation of any new price and the length of the offer.

What cancelling saves you

Example calculation using 4G Home Broadband 24 months at £22 per month and Hyperoptic competitor at £17 per month.

3 WiFi 4G Home Broadband: £22 x 12 = £264 per year.

Hyperoptic alternative: £17 x 12 = £204 per year.

Yearly saving: £264 - £204 = £60 per year. Calculation shown: 22 x 12 = 264; 17 x 12 = 204; 264 - 204 = 60.

Other plans from 3 WiFi useful for comparison: 5G Home Broadband £28 per month (£336 per year), Mobile Wi-Fi Unlimited from £22 per month (£264 per year), Mobile Wi-Fi 10GB from £10 per month (£120 per year). Choose the cheapest real alternative listed: Hyperoptic at £17 per month.

What to do after cancelling 3 WiFi

Check final bill and refunds

Review the final invoice for outstanding charges and any early termination charges if applicable. If you cancelled within the cooling-off period, expect a refund for returnable items and unused allowances as described by Three; exceptions include certain PAYG items bought in store.

Return equipment

If you had Home Broadband equipment, follow Three instructions for returning the router or hub. Failure to return required equipment can result in a non-return charge as stated in Three terms.

Access and data

After cancellation your account access may close. Back up any account or device settings, and save bills or usage records you may need for disputes. If you used a Three email address, arrange to move any important messages before the account is closed.

Re-activation and new services

If you decide to re-join Three later, new plan pricing and any joining offers will apply. Keep any proof of prior cancellation if disputing early termination charges later.

Next steps and practical checklist

Use this checklist after you decide to cancel 3 WiFi.

  • Find your account number and the email or billing address tied to the account.
  • Decide cancellation method: phone (333), post to PO Box 333 G2 9AA, or online via account.
  • If within cooling-off: prepare order confirmation and return plan or device when instructed.
  • If sending post, send by registered post and keep proof of postage.
  • Ask for a cancellation reference number and the effective termination date and write them down.
  • Check final bill for early termination fees. If amount is non-published, request a detailed breakdown.
  • Return any provider equipment as instructed to avoid non-return charges.
  • Save all confirmation emails, chat transcripts and call reference numbers for 6 to 12 months.
