Refund & Cancellation Policy

Last updated: 06/12/2025

1. Overview of subscriptions

GasTheory offers access to premium revision content and features on a subscription basis. Subscriptions are billed in advance for each billing period (for example, monthly) and renew automatically until cancelled.

2. Free content

Some content may be available free of charge to help you evaluate whether GasTheory is right for you. You can explore this content before deciding to subscribe.

3. Cancelling your subscription

You can cancel your subscription at any time from within your account area. Once cancelled, you will retain access to premium content until the end of your current billing period, after which you will not be charged again.

4. Refunds for subscription payments

Because GasTheory provides immediate access to digital content and revision tools, subscription fees are generally non-refundable. However, we may issue a refund in limited situations, such as:

  • Duplicate payments or clear billing errors; or
  • Extended technical issues that prevent you from accessing the Service after you have contacted support and given us a reasonable opportunity to fix the problem.

If you believe you are entitled to a refund, please contact us at contact@plumbtheory.co.uk with details of your account and the issue.

5. Your legal rights

Nothing in this policy is intended to limit any statutory rights you may have under consumer law in your country. If local law provides you with additional rights, those rights will apply in addition to this policy.
