Applicable law: Non statutory procedural; use company policy and rights under Consumer Rights Act 2015 where service performance is relevant.

Legitimate grounds accepted by Three

Three accepts cooling-off, price increase, service unavailability at a new address and bereavement as grounds used in practice. For issues with speed or service quality, under the Consumer Rights Act 2015 you may be entitled to a remedy including cancellation.

Applicable law: Consumer Contracts Regulations 2013 for contract formation and Consumer Rights Act 2015 for unfair terms.

Cooling-off period (14 days)

For contracts concluded online or off-premises you have a 14-day cooling-off period under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. To cancel within 14 days you must return equipment undamaged in original packaging, including any supplied SIM cards, leads, and accessories. If equipment is not returned or is damaged, Three will charge the replacement cost. The 5G Hub fee for failure to return is £350 inside the cooling-off period and £105 outside the cooling-off period.

Applicable law: Consumer Contracts Regulations 2013.

Before you cancel: negotiate

Three may offer retention options when you contact them to cancel. The publicly reported retention tools are billing adjustments, plan changes to lower-monthly price or payment method discounts. The research does not list specific guaranteed discounts offered on cancellation calls. When you call, request any retention offers, a lower monthly tariff, or a switch to a 24 month plan at a lower price. Ask for the offer in writing or a confirmation email.

What cancelling saves - concrete math

Example using published prices: Three Unlimited Home Broadband 24-month plan at £18.00 per month costs 18.00 x 12 = £216.00 per year. The cheapest competitor listed is Vodafone at £24.00 per month which costs 24.00 x 12 = £288.00 per year. Yearly saving by staying on the Three £18 plan versus switching to Vodafone £24 is: £288.00 - £216.00 = £72.00 per year. Calculation: "£18.00 x 12 = £216.00" and "£24.00 x 12 = £288.00" so saving = "£72.00".

Published plan examples used: Three 24-month plan £18.00, Three 12-month plan £22.00, Three 1-month plan £30.00. Competitor prices used: Vodafone £24.00, Plusnet £28.00, Zen Internet £40.00.

Consumer laws that apply

Your cancellation and refund rights are protected by the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 which gives a 14-day cooling-off period for contracts concluded online or off-premises. The Consumer Rights Act 2015 requires services to be provided with reasonable care and skill and prohibits unfair contract terms including disproportionate cancellation penalties.

What to do if Three refuses a lawful cancellation

If Three refuses a lawful cancellation, complain to Three in writing first and keep copies. If unresolved, contact Citizens Advice for next steps: Citizens Advice - cancelling a phone, TV, internet or mobile contract. For systemic problems raise a complaint with the Communications Ombudsman or use a payment chargeback if you paid by card.

Auto-renewal and tricky cancellation clauses

The Competition and Markets Authority treats hard-to-cancel subscriptions and unclear auto-renewal terms as potential unfair practice. If your contract auto-renews and the renewal term or notice is unclear, challenge it referencing CMA guidance and the Consumer Rights Act 2015.

Returning equipment

If you had a 5G Hub return it using the pre-paid returns bag that Three provides. Failure to return the 5G Hub will result in a fee of £350 if inside the cooling-off period, and £105 if outside the cooling-off period. For other hub types return instructions and charges will be provided by Three.

Final bill and refunds

Three issues the final bill within 38 days of cancellation. Monthly charges continue to be billed until the final bill; any overpayments are credited. Refunds for credit balances over £0.50 will be processed within 14 days of the final bill to the bank account or card used for payment. Refunds under £0.50 can be arranged by calling 0333 338 1993 or using Live Chat.

Access to account records

You can view and pay bills for up to 18 months after cancelling by logging into My3. Keep copies of final bills and refunds as proof if you need to escalate the complaint.
