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.
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.
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.
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.
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.
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.
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.
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.
The main protections are the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 and the Consumer Rights Act 2015. The 2013 Regulations give a 14 day cooling-off period for distance and off-premises contracts and 30 days for Home Broadband and Business Broadband per Three guidance. See legislation.gov.uk.
For disputes, contact Three first. If unresolved, seek help from Citizens Advice for next steps and options to escalate to the Communications Ombudsman. Citizens Advice contains guidance on cancelling phone, internet and TV contracts: Citizens Advice - cancelling contracts.
The Consumer Rights Act 2015 provides remedies where services are not carried out with reasonable care and skill or where contract terms are unfair. If Three applies disproportionate cancellation penalties, that term may be challenged under the Consumer Rights Act 2015.
If you paid by credit card, consider Section 75 or chargeback via your card issuer for qualifying payments. File a formal complaint with Three and retain evidence, then escalate to the Communications Ombudsman if Three does not resolve the issue.
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.
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.
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.
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.
