If you move out of the UK and cannot use Dexcom services, contact Dexcom support with proof of new address such as a utility bill or tenancy agreement. Dexcom does not publish a specific moving cancellation form. If purchased online, the Consumer Contracts Regulations 2013 apply for distance sales.
Applicable law: Consumer Contracts Regulations 2013.
If Dexcom raises the price of an ongoing subscription and you want to cancel because of that increase, check the contract terms and contact Dexcom to cancel. The CMA treats unclear auto-renewal and unfair price increase terms as potential unfair practices. If the increase breaches contract rules, you can raise a complaint and rely on consumer rights.
Applicable law: Competition and Markets Authority guidance on unfair contract terms; Consumer Rights Act 2015.
Dexcom has not published specific instructions for cancelling on grounds of death. If this situation applies, contact Dexcom at [email protected] and supply a copy of the death certificate and account evidence; request account closure and refund where applicable. Dexcom return and refund terms will apply to unopened products.
Applicable law: Not published by Dexcom; general consumer protections under Consumer Rights Act 2015.
Dexcom accepts returns and refunds for damaged products reported within four days of receipt and accepts cancellations under the Consumer Contracts Regulations 2013 within 14 days for distance sales. Dexcom does not accept returns of opened products for safety and hygiene reasons. Products funded by the NHS are non-refundable per Dexcom policy.
Applicable law: Dexcom return policy and Consumer Contracts Regulations 2013. See Official return policy.
For Dexcom subscriptions labelled "cancel anytime" there is no minimum term; cancel via the webshop, by email or phone. For other contracts, check your order confirmation for any minimum commitment. Dexcom publishes "cancel anytime" terms for specific products. See product terms.
Applicable law: Consumer Rights Act 2015.
Under the Consumer Contracts Regulations 2013 you have a 14 day cancellation period for online or off-premises contracts. If multiple products are delivered separately, the 14-day period starts the day after receiving the last product. Dexcom requires returned products to be received within 28 days after notification of return.
Applicable law: Consumer Contracts Regulations 2013; see legislation and the Digital Markets, Competition and Consumers Act 2024 for subscription renewal cooling-off rights at section 267.

The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 provide a 14 day cooling-off right for distance and off-premises contracts. The Consumer Rights Act 2015 protects against unfair contract terms and requires services to be performed with reasonable care and skill.
The Digital Markets, Competition and Consumers Act 2024 includes strengthened cooling-off and renewal protections for subscription contracts and prevents unfair auto-renewal practices. See the enacted section on cooling-off at section 267 and the legislation page at Digital Markets Act - cooling-off.
First raise a complaint with Dexcom using their complaints procedure: Dexcom complaints procedure. If unresolved, contact Citizens Advice for guidance. For card payments over £100 and up to £30,000, consider Section 75 or card issuer chargeback. If the issue concerns unfair terms or hard-to-cancel subscriptions, the Competition and Markets Authority (CMA) may be able to help.
Check your bank or card statement for any final charge. If you cancelled within the 14 day cooling-off period and returned unopened products, Dexcom will reimburse payments excluding original delivery charges within 14 days of receiving and checking returns. Reimbursement is by the original payment method unless otherwise agreed.
To be eligible for a refund products must be unused, undamaged and have intact seals; opened products are not accepted for safety and hygiene. Damaged products reported within four days of receipt may be refunded or exchanged. Once you notify Dexcom of a return, Dexcom requires that products are received within 28 days.
If you used Dexcom mobile apps, download any data you need before account closure. For technical or account data requests contact [email protected]. If you later re-subscribe, re-activation steps depend on product and account status; contact Dexcom for re-activation details.
