Cancel by reason

Cooling-off (change of mind)

You have a 14 day Cooling-off Period for services ordered online, by phone or by mail-order. For Home Broadband you have 30 days from receiving your Hub to return it and cancel the Home Broadband or Mobile Broadband services. Start point is delivery or activation as set out in Three returns guidance. Use the online cancellation form or call customer services and request a refund.

Applicable law: Consumer Contracts Regulations 2013.

End of minimum commitment

If your minimum term ends, contact Three to cancel. Three requires a 30 day notice period after the Cooling-off Period for most contract cancellations; the earliest effective date will normally be 30 days from the cancellation request if outside Cooling-off. Check your contract for the exact end date.

Applicable law: Consumer Rights Act 2015 (contract performance obligations).

Price increase

If Three raises your contract price and your contract or price guide permits annual increases, you may have a contractual right to cancel without penalty depending on the terms. Check the price change notice you received. If the increase breaches your contract terms or is not permitted, you may terminate and seek remedies under consumer law.

Applicable law: Consumer Rights Act 2015.

Death of subscriber

To cancel a contract after the named subscriber dies, contact Three Customer Services and be ready to provide the death certificate and proof you are the executor or next of kin. Three's published documents do not set the exact process; Three will advise on documentation and any refund or remaining obligations once contacted.

Applicable law: Consumer Rights Act 2015.

Moving abroad

If you move outside Three's service area, contact Three and provide proof of new address. Contract exit rights depend on the contract terms; Three's public documents do not list a specific auto-exit policy for relocation, so submit proof and request cancellation terms in writing.

Applicable law: Consumer Rights Act 2015.

Legitimate grounds accepted by Three

Three accepts cancellation within the 14 day Cooling-off Period, refunds for unused Pay As You Go credit within Cooling-off, and contractual cancellation with notice after Cooling-off. For other legitimate grounds such as faulty service or misleading information, statutory remedies apply under the Consumer Rights Act 2015.

Applicable law: Consumer Contracts Regulations 2013; Consumer Rights Act 2015.

Negotiate or save

Before you cancel - negotiate

Contact Three Customer Services and request a retention offer. Three commonly offers bill credits, discounted months or handset repayment adjustments at retention. If you have a 24 month contract, ask for an adjustment to the monthly tariff or a temporary discount. If Three does not provide a written offer, request an email summarising any proposed change so you can compare formally.

What cancelling saves - example calculations

Choose your current plan from Three pricing and compute annual cost to show potential savings when switching.

  • SIM Only Advanced 24 month (Unlimited) - £22 per month. Yearly cost: 12 x £22 = £264 per year.
  • SIM Only Advanced 12 month (Unlimited) - £26 per month. Yearly cost: 12 x £26 = £312 per year.
  • 24 Month Lite Plan - 40GB - £16.00 per month. Yearly cost: 12 x £16 = £192 per year.
  • Pay As You Go 40GB - £10 per month. Yearly cost: 12 x £10 = £120 per year.
  • Pay As You Go Unlimited 1 month - £35 per month. Yearly cost: 12 x £35 = £420 per year.

Cheapest clear alternative - for many users a Pay As You Go 40GB pack at £10 per month from Three saves versus a £22 unlimited SIM only plan: annual saving = £264 - £120 = £144 per year. If you move to Three Pay As You Go 40GB at £10, the computation is 12 x £22 - 12 x £10 = £264 - £120 = £144 saved per year.

What to do after cancelling Three

Access and data

Back up contacts, photos and any content stored on Three services before cancellation. If you used Three cloud or email services, export data while your account remains active.

Final bill and refunds

Check the final invoice for prorated charges, early cancellation fees if applicable and any refunds due from unused Pay As You Go credit within Cooling-off. If you requested a refund under Cooling-off, Three will process it per their returns policy; allow time for processing and bank clearing.

Re-activation and number porting

If you want to keep your number, obtain a PAC or PAC code before finalising cancellation. Without a PAC you may lose your number. To rejoin Three later, sign up again; prior contractual liabilities remain settled at cancellation.

Next steps and practical checklist

Use this checklist to prepare your cancellation and protect your data and money.

  • Find your account number and contract end date.
  • Decide if you will use Cooling-off (14 days) or cancel after minimum term (30 days notice normally).
  • Back up contacts, photos and exports of any cloud data.
  • Request a PAC code if you want to keep your phone number.
  • Call 333 or 0333 338 1001, or complete the Cancellation Form and keep proof.
  • Send post by recorded delivery if using postal cancellation and keep receipt.
  • Track final bill and check for refunds or early cancellation fees.
