Rule: You have a 14 day cooling-off period for contracts concluded online, by phone or off-premises for most services. For Home/Business Broadband the cooling-off period is 30 days. To exercise this right request cancellation and return items if applicable within the period and you are entitled to a refund.
Required proof: Date of order or SIM delivery, order reference or confirmation email. Law: Consumer Contracts Regulations 2013.
Rule: At the end of the Minimum Term you can cancel without early termination charges. Three states customers agree to remain Connected for the Minimum Term specified in their plan. Required proof: Contract end date from your bill or Three account.
Rule: If Three makes changes to the agreement that are not acceptable and they notify you, you have the right to terminate without a Cancellation Fee if you notify within the stated notice from Three. Required proof: Three's notice to you of the change and your written notification to terminate. Law: Contractual change rights as set out in Three's terms and Consumer Rights Act 2015 protections on unfair terms.
Rule: Moving outside the UK is not automatically a legitimate ground for fee-free termination unless Three's terms allow it. Required proof: Documentary evidence of new address or relocation that meets Three's terms. Law: Consumer Rights Act 2015 provides remedies where services cannot be provided with reasonable care and skill.
Rule: When the account holder dies contact Three with the death certificate and proof of executor or next of kin. Required proof: Death certificate and account details. Three's published terms set out the required evidence for account changes after death.
Rule: Three accepts specific legitimate grounds such as material contractual changes notified by Three or cancellation within the Returns Period as set in their terms. Required proof: The notice from Three or notification within the Returns Period. Law: Consumer Rights Act 2015 and Three's published terms.
What to ask for: Ask customer services for retention offers, a SIM-only discount, a plan downgrade or a fixed-price deal. Research: no specific retention offers are published by Three in the provided data. How to request: Call 333 or 0333 338 1001 and say you want to leave - request any available retention discount, a shorter minimum term or a SIM-only price reduction. Keep the agent reference number for any agreed change.
Example yearly saving calculation: compare your monthly fee with the cheapest competitor listed in research. Competitor cheapest example: Tesco Mobile at £7 per month.
If you currently pay £12.15 per month with Honest Mobile equivalent plan, yearly cost is 12.15 x 12 = £145.80 per year. Switching to Tesco Mobile at £7 x 12 = £84 per year saves 12.15 x 12 - 7 x 12 = £145.80 - £84 = £61.80 per year.
Competitor monthly and annual prices used in this guide: Vodafone £8 per month (£96 per year), VOXI £10 per month (£120 per year), Tesco Mobile £7 per month (£84 per year), Honest Mobile £12.15 per month (£145.80 per year).
The Consumer Contracts Regulations 2013 give a 14 day cooling-off period for distance and off-premises contracts; Home/Business Broadband has a 30 day right to cancel as published by Three. The Consumer Rights Act 2015 requires services to be performed with reasonable care and skill and protects against unfair contract terms and disproportionate cancellation penalties.
Step 1: Complain to Three using the customer service channels and keep records. Step 2: If unresolved, seek advice from Citizens Advice at Citizens Advice - cancel a service. Step 3: For unresolved communications sector complaints, contact the Communications Ombudsman. For misleading or unfair auto-renewal practices, the Competition and Markets Authority (CMA) may be relevant. For card payments you may explore chargeback or Section 75 if applicable.
Keep copies of the cancellation confirmation, PAC/STAC code or proof of posting. Your final bill may include outstanding charges and any early termination fee calculated as published in Three's terms. If your account is in credit when it closes, Three will refund owed amounts within 14 days of the final bill where eligible.
If you were provided with broadband equipment you must return it as required. If equipment is not returned a non-return charge will apply as stated in Three's returns and terms. Back up any data on your device - Three will not retain personal content after account closure.
Follow this checklist to cancel cleanly and minimise charges.
