Cancel by reason
Moving - change of address
If you move and cannot attend group sessions, provide proof such as a new utility bill or tenancy agreement. Slimming World does not publish a special rule for moving; supply documentation to support your request for termination or transfer of membership.
Applicable law: Consumer Rights Act 2015 - services must be performed with reasonable care and skill.
Price increase
If Slimming World raises your subscription price, check the terms you agreed. If the increase is applied mid-contract and you do not accept it, you have a right to cancel. Provide the notification you received from Slimming World as proof.
Applicable law: The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.
Death of the subscriber
If the subscriber dies, a close relative or executor should contact Slimming World and send a copy of the death certificate. This is accepted evidence to close the account and stop further billing.
Applicable law: Consumer Rights Act 2015 for contract cancellation due to death affecting ability to perform a service.
Legitimate ground (medical or long-term incapacity)
For long-term illness or medical incapacity, provide supporting letters from a GP or consultant. Slimming World will consider requests supported by medical evidence; the company does not publish a fixed list of accepted grounds.
Applicable law: Consumer Rights Act 2015.
End of commitment
For online Bronze, Silver and Gold starter packages there is an initial 3-month commitment. After the initial period, the subscription automatically renews at £20 per month unless cancelled. Provide your original welcome or confirmation email to show the initial term.
Applicable law: Clear contract terms must be provided under the Consumer Contracts Regulations 2013.
Cooling-off (change of mind)
You have a 14-day cooling-off right for distance and off-premises contracts under the Consumer Contracts Regulations 2013. To use it send a cancellation notice within 14 days of entering the contract. If you requested services during the cooling-off period you may owe payment for the services supplied up to cancellation.
Applicable law: The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 and the statutory cooling-off rules in the Consumer Rights Act 2024.
Negotiate or save
Before cancelling: negotiate
Retention offers are not widely published. Research shows Slimming World provides tiered online packages and may offer Countdown courses as commitment-boosting options. To negotiate, contact Slimming World support via your account or by email, request a retention offer or ask for a pause. If you are moving to a different format (online instead of group) ask for transfer options and any available discounts. Keep written proof of any offer.
What cancelling saves you
Calculate yearly cost for the main plans from research and the cheapest listed competitor.
Slimming World Online - ongoing monthly: £20 x 12 = £240 per year.
Group membership - weekly fee: £6.95 x 52 = £361.40 per year.
Group membership - first week fee: £11.95 (one-off on joining).
Online starter bronze: £60 for 3 months initial then £20/month thereafter.
Cheapest competitor listed: The Fast 800 at £20 per month which equals £20 x 12 = £240 per year.
Example saving: cancelling a weekly group membership at £6.95/week and switching to online at £20/month saves: £361.40 - £240 = £121.40 per year.
Legal protections and escalation
Key UK consumer law
You are protected by the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 which gives a 14-day cooling-off right for distance and off-premises contracts. See the legislation: Consumer Contracts Regulations 2013. The Consumer Rights Act 2015 requires services to be provided with reasonable care and skill.
Refunds and statutory rights
If you cancel within 14 days you are entitled to a refund of payments already made unless you asked for service to start in the cooling-off period; in that case the trader may charge for the portion of service supplied. Citizens Advice explains how to cancel and claim a refund: Citizens Advice - cancelling a service.
Auto-renewal and unfair terms
The Competition and Markets Authority treats hard-to-cancel auto-renewals as potentially unfair. If Slimming World used unclear auto-renewal terms, escalate the complaint, keep evidence of the original terms and the renewal notice.
Escalation steps
1. Complain to Slimming World in writing and keep evidence. 2. If unresolved contact Citizens Advice for next steps. 3. For card payments check Section 75 or ask your card issuer for a chargeback. 4. If contractual terms are unfair, report to Trading Standards or the CMA.
What to do after cancelling Slimming World
Check access and final billing
After cancellation verify when access ends and whether you owe any final charges. For online subscriptions cancelled within the app store, access usually continues until the paid period ends; keep the cancellation confirmation from Apple or Google Play as proof.
Data and account
Request confirmation of account closure and ask how long Slimming World retains your personal data. If you want data deleted, send a subject access request or deletion request via the contact channels in the terms of use.
Re-activation and records
If you plan to rejoin later, note any joining fees that applied when you first joined. Save copies of final invoices, confirmation emails and proof of delivery for post cancellations by post.

- Identify whether you subscribed via Slimming World website, iOS or Google Play.
