Cooling-off (change your mind)

Rule: Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 you have 14 days from the day after you receive goods or from the date of agreement for services bought at a distance to cancel and obtain a refund.

Required proof: Notify Three Customer Services within 14 days and send back the item within the following 14 days where applicable. Keep proof of notification and postage.

Applicable law: Consumer Contracts Regulations 2013. See Which - Consumer Contracts Regulations.

End of minimum commitment

Rule: At the end of your contract term (for example after 12 or 24 months) you can stop the service without an early termination charge. Three publishes 24-month and 12-month plan options and a 1-month option.

Required proof: No specific proof needed; cancel before the renewal date or contact Customer Services to confirm the end-of-term cancellation.

Applicable law: Consumer Rights Act 2015 protections on unfair contract terms if penalties are disproportionate.

Price increase

Rule: If Three increases your monthly price mid-contract and your contract or the change violates consumer fairness, you may have grounds to end the contract without penalty. Three's price guides note scheduled increases (for example a stated 4.5% increase each April for some plans).

Required proof: Keep copies of your original contract, price guides (Three price guides), and the notification of the increase from Three.

Applicable law: Consumer Rights Act 2015 and CMA guidance on unfair auto-renewal and unexpected charges.

Device return / faulty goods

Rule: For devices purchased online or by telesales you can return within 14 days of receipt; refunds issued after Three receives the device or proof of return. Three may deduct for missing or damaged items.

Required proof: Proof of postage and condition of the product; keep returns reference or tracking. See Three's returns policy for customers who joined on or before 29 Jan 2023.

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

Before you cancel: negotiate

Three does not publish a standard list of retention offers. When you contact Customer Services to cancel, ask explicitly for a retention offer, tariff downgrade, or a switched-to month-to-month plan. If you are in contract, request the exact financial effect (monthly price after retention, any change to the contract length) and ask for a written confirmation of any new offer. If Three does not provide an offer, record the agent's name and any reference number.

What cancelling saves you - example calculations

Use these real prices from Three when comparing the yearly cost and potential savings versus an alternative.

• Three 4G Home Broadband (24 months): £24 per month. Yearly cost: 24 x 12 = £288 per year.
• Three 4G Mobile Broadband (24 months): £22 per month. Yearly cost: 22 x 12 = £264 per year.
• Three 5G Mobile Broadband (24 months): £28 per month. Yearly cost: 28 x 12 = £336 per year.

Cheapest listed alternative from competitors: Hyperoptic at £17 per month. Yearly cost: 17 x 12 = £204 per year.

Examples of savings if you cancel Three and switch to Hyperoptic:

• Switch from Three 4G Home Broadband £24: saving = (24 - 17) x 12 = £84 per year.
• Switch from Three 4G Mobile Broadband £22: saving = (22 - 17) x 12 = £60 per year.
• Switch from Three 5G Mobile Broadband £28: saving = (28 - 17) x 12 = £132 per year.

Key UK consumer law

The main laws that protect you are the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 which give a 14-day cooling-off right for distance sales and the Consumer Rights Act 2015 which requires services to be performed with reasonable care and skill and prevents unfair contract terms.

Refund timing and rights

If you cancel within the 14-day cooling-off period you are entitled to a refund of payments made for services and any upfront device payments once the device is returned or proof of return is provided. Refunds should be processed within 14 days of the trader getting the goods back or receiving proof of return where applicable.

How to escalate

1) Complain to Three first and keep evidence. 2) If unresolved, get help from Citizens Advice: Citizens Advice - changing your mind. 3) If you still cannot resolve, escalate to the Communications Ombudsman or lodge a Section 75/chargeback with your card issuer if payment qualifies.

Regulator

The Competition and Markets Authority (CMA) monitors unfair contract terms, including unclear auto-renewal. Use official price guides and contract terms to check for permitted price increases; Three publishes price guides and terms on their site.

Check final billing

After cancellation expect a final bill. If you cancelled within 14 days for a distance purchase, request a refund of unused allowances or any upfront device payments once Three receives returned devices or proof of postage.

Device returns and refunds

Three will only refund money paid upfront for devices once they have received the device or evidence you posted it. They may deduct charges for missing or damaged items or if the device is not returned in 'as new' condition.

Data and account access

Back up any account settings, WiFi passwords, router configurations or personal data tied to the service before cancellation. If your broadband uses a Three SIM, keep the SIM number and account details in case you need to reconnect or port numbers.

Re-activation and switching

If you later want to rejoin Three, new offers may apply; if you switch to another provider, check whether they will cover any exit fees (Hyperoptic advertises bill credits for exit fees in some cases) and schedule installation dates to avoid service gaps.

Use this checklist to complete cancellation and protect your rights.

• Find your contract length and next renewal date.
• If within 14 days of purchase, notify Three Customer Services and request a return form immediately.
• If returning a device, call 0333 300 0330 (three.co.uk orders) or 0333 300 3333 (Telesales) to arrange returns and use tracked postage to PO Box 333, Glasgow, G2 9AG.
• If cancelling by phone, call 500 from a Three phone or 0333 338 1003 from another phone and note the agent name and reference.
• Keep copies of all correspondence, proof of posting, screenshots, and any case numbers.
• Check final bill for charges for services used before cancellation and for any device deductions.
• If you dispute a charge, escalate to Citizens Advice or the Communications Ombudsman with your evidence.
