Terms of service

These terms govern use of CBAMReturn (the “service”) at https://cbamreturn.co.uk, operated by the founder-owned business trading as CBAMReturn (“we”). By creating an account or using the free tools you agree to them. Plain English throughout; where a heading and the text differ, the text wins.

1. What the service is

Software that helps UK importers and their agents prepare for the UK Carbon Border Adjustment Mechanism: threshold monitoring, indicative liability, supplier data collection, records keeping and reporting. Figures are indicative, computed from the inputs you supply and from labelled public sources and scenario inputs where HMRC has not yet published official ones. The service is general information and tooling, not tax, legal or accounting advice. You remain responsible for your registrations, returns and payments to HMRC and for the accuracy of what you upload.

2. Founding access and price

Accounts created before January 2027 have free founding access until then. From January 2027 the importer service costs £149 per month or £1490 per year per importing entity, excluding VAT, and that rate is locked for founding members through the first two compliance years (2027 and 2028). We give at least 30 days' notice before any billing begins; you can close your account at any time before then and pay nothing. Broker and partner pricing is agreed in writing separately.

3. Your account and your organisation

You must give accurate details and keep your sign-in secure; we recommend two-step verification. An organisation's owners control who belongs to it and what they can do. Where a customs broker or other agent creates a client workspace, the agent is responsible for having the client's authority to hold and process that client's data, and our data processing terms apply.

4. Your data

You own everything you upload. We process it only to provide the service, as described in the privacy policy. The free preview tools process files in memory and store nothing. Saved ledgers, records-vault documents and audit logs are stored on infrastructure in the United Kingdom, backed up nightly, and are yours to export in full at any time from the account. Deleting a ledger, a document, an organisation or an account removes the corresponding data; backups age out within 30 days.

5. Acceptable use

Do not upload material you have no right to hold, attempt to access other organisations' data, probe or overload the service, or resell it without a written partner agreement. We may suspend access that threatens the service or other customers, and will tell you why.

6. Availability and changes

We aim for continuous availability but do not guarantee it; planned maintenance is announced in the account where practical. The rules the service implements are changing through 2026 and 2027; we track primary sources and publish every change on the changelog. We may improve or change features; we will not remove your ability to export your data.

7. Liability

Nothing in these terms limits liability that cannot be limited by law. Otherwise, our total liability to you in any 12-month period is limited to the fees you paid us in that period (and, during founding access, to £100), and we are not liable for indirect or consequential loss, or for tax, penalties or interest assessed by HMRC. The service depends on the accuracy of your inputs and of published rules; we do not warrant that indicative figures will match final assessments.

8. Ending the agreement

You can delete your account from the security page at any time. We can end the agreement on 30 days' notice, or immediately for material breach, and will provide an export window of at least 30 days in either case.

9. Law and contact

These terms are governed by the law of England and Wales, and its courts have exclusive jurisdiction. Questions: hello@cbamreturn.co.uk. Related: privacy · data processing terms · subprocessors.
