If you move and the service cannot be provided at the new location, send proof such as a tenancy agreement or utility bill in the new address and a request to cancel. Brilliant does not publish an explicit relocation policy; include supporting documents in your email to [email protected]. Applicable law: Consumer Contracts Regulations 2013 cooling-off and contract termination principles.
If Brilliant increases the price at renewal and you do not agree, you may cancel the renewed contract. Send evidence of the price increase (email or terms change) and request cancellation. Under UK rules on subscription renewals, a renewal cooling-off notice must be provided and any refund obligation disclosed. See Brilliant terms.
Provide a copy of the death certificate and the account holder details to support email to request account closure and stop renewals. Cite the contractual end on grounds of death and request confirmation from Brilliant.
Research shows Brilliant considers exceptional circumstances case by case for refunds. Examples accepted voluntarily include quick refund after accidental renewal. Provide proof such as a bank charge date, account inactivity evidence, or trial cancellation date. Statutory rights: Consumer Contracts Regulations 2013 and Consumer Rights Act 2015 apply where digital content was paid for but not used or where services were not performed with reasonable care and skill.
When your paid period ends you are not obligated to continue. Cancel before the renewal date using the web or store subscription settings to avoid automatic renewal charges. If you cancel via the website but later sign in, take care not to inadvertently reactivate the account; retain your cancellation confirmation.
UK law grants a 14-day cooling-off period under the Consumer Contracts Regulations 2013 for most online contracts. Digital content exceptions apply once download or streaming has started with the consumer's express consent. For renewals a renewal cooling-off period and cooling-off notice rules apply; see the UK legislation on renewal cooling-off rights at UK legislation (2024).
Brilliant offers refunds and credits only at its sole discretion. Research includes reports of quick refunds if requested promptly: a Trustpilot testimonial states, "My test trial renewed automatically I requested a refund and they accepted in not even a day very good Support and good app". If you want to keep the service, request a retention offer by emailing [email protected] or [email protected] and state the exact reason you plan to cancel and the date of renewal. Ask specifically for a prorated refund or discounted annual rate. There is no standard published retention discount.
Brilliant Premium monthly costs £15.49. Monthly cost annualised: 15.49 x 12 = 185.88, so annual cost = £185.88. Switching from Monthly to Annual does not save if annual is priced at the same equivalent, but buying an annual plan locks the price for 12 months at £185.88. By cancelling Premium monthly you save: 15.49 x remaining months. Example: cancelling on month 3 saves 15.49 x 9 = £139.41 for remaining months.
Cheapest competitor from our list: Khan Academy is free at £0, saving compared with Brilliant annual: 185.88 - 0 = £185.88 per year. Greymill costs £100 per month or £1200 per year. AskRegulus costs £29 per month or £348 per year. Compare yearly costs: Brilliant annual £185.88, AskRegulus annual £348, Greymill annual £1200. Switching from Brilliant Premium annual to AskRegulus would cost an extra 348 - 185.88 = £162.12 per year.
The Consumer Contracts Regulations 2013 provide a 14-day cooling-off period for online purchases and require refunds when contracts are cancelled during that period, subject to exceptions for digital content once download or streaming has started. The Consumer Rights Act 2015 requires services to be performed with reasonable care and skill and prohibits unfair contract terms such as disproportionate cancellation penalties.
The Competition and Markets Authority treats hard-to-cancel subscriptions and unclear auto-renewal terms as potentially unfair. If Brilliant's renewal communications or cancellation process are unclear you can raise a complaint with Citizens Advice for next steps.
1. Complain to Brilliant support and keep records (emails, screenshots, dates). 2. If unresolved, get guidance from Citizens Advice. 3. For qualifying card payments, consider Section 75 or a chargeback via your card issuer. 4. If the dispute relates to a regulated sector, escalate to the relevant ombudsman. Cite Consumer Contracts Regulations 2013 and Consumer Rights Act 2015 when relevant.
After cancellation verify whether access continues until the end of your paid period or ends immediately. Save screenshots of the cancellation confirmation and any final billing notice. Check your payment method to confirm no further charges occur.
Decide whether to delete your account or keep it. If you want your data removed, request account deletion by emailing [email protected]. Keep copies of any confirmation. If you reactivate by signing in you may re-enable the subscription; do not sign back in until you are ready to restart the service.
