Cancel by reason

Moving abroad or relocation

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.

Price increase

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.

Death of subscriber

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.

Legitimate grounds accepted by 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.

End of commitment

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.

Cooling-off period

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).

Negotiate or save

Before you cancel - negotiate

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.

What cancelling saves you - exact maths

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.

What to do after cancelling Brilliant

Check access and billing

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.

Data and account recovery

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.

Next steps and practical checklist

Use this checklist to cancel and protect yourself.

  • Find your account email and last four digits of payment card.
  • Cancel in the place you originally subscribed: Brilliant web account or the store (Apple/Google) used for purchase.
  • Save screenshot of cancellation confirmation and confirmation email.
  • If charged after cancellation, email [email protected] and include proof of cancellation and the charge date.
  • If you requested a refund, save the support reply. If refused and you believe UK consumer law protects you, contact Citizens Advice and your card issuer for chargeback/Section 75 options.
  • If sending a registered letter, use the postal address: Brilliant, Crown Way, CF14 3UZ Cardiff, United Kingdom.
