Terms of Service

Last updated: May 2026

1. Acceptance of terms

By creating an account and using VATBuild, you agree to be bound by these Terms of Service ("Terms"). If you do not agree, you must not use the service.

These Terms form a legally binding agreement between you and VATBuild (the "Service"). We may update these Terms from time to time. Continued use after changes constitutes acceptance.

2. Service description

VATBuild is an online software tool designed to help UK self-build construction project owners analyse invoices, classify VAT reclaim eligibility in accordance with HMRC Notice 708, and generate reports for submission to HM Revenue & Customs.

The Service uses artificial intelligence to assist with document analysis and VAT classification. Access to the Service requires registration and is subject to any applicable subscription fees.

3. Eligibility

You must be at least 18 years old and have the legal capacity to enter into a binding contract to use this Service. By registering, you confirm that this is the case.

The Service is intended for use in the United Kingdom. We make no representation that the Service is appropriate or available in other jurisdictions.

4. Your account

You are responsible for keeping your account credentials secure. You must not share your account with others or allow unauthorised access.

You are responsible for all activity that occurs under your account. If you suspect unauthorised access, you must notify us immediately at support@vatbuild.co.uk.

We reserve the right to suspend or terminate accounts that violate these Terms, engage in fraudulent activity, or pose a risk to other users or the Service.

5. Acceptable use

You agree to use the Service only for lawful purposes. You must not:

  • Upload documents you do not have the right to use or share
  • Use the Service to make fraudulent or false VAT claims
  • Attempt to gain unauthorised access to any part of the Service
  • Use automated tools to scrape or extract data from the Service
  • Upload content that is illegal, defamatory, or infringes third-party rights
  • Interfere with or disrupt the integrity or performance of the Service

6. AI output disclaimer — not professional tax advice

The AI-generated analysis, VAT classifications, and suggestions provided by VATBuild are for informational purposes only and do not constitute professional tax, legal, or financial advice.

VAT rules are complex and depend on the specific facts of your project. You must verify all classifications and claim amounts with a qualified accountant, tax adviser, or VAT specialist before submitting any claim to HMRC. VATBuild accepts no responsibility for the accuracy of AI-generated output or for any loss arising from reliance on it without independent professional verification.

HMRC allows only a single VAT431NB (self-build VAT reclaim) submission per project. Any errors in that submission cannot be corrected by resubmitting. It is your responsibility to ensure the accuracy of your claim.

7. Your data and content

You retain ownership of all documents and data you upload to VATBuild. By uploading content, you grant us a limited licence to process that content solely for the purpose of providing the Service to you.

We do not sell your data. Please see our Privacy Policy for full details of how we handle your personal data.

8. Intellectual property

The VATBuild software, brand, and all associated materials are owned by us and protected by intellectual property law. You may not copy, modify, or distribute any part of the Service without our prior written consent.

9. Liability limitations

To the fullest extent permitted by law:

  • The Service is provided "as is" without warranties of any kind, express or implied
  • We do not warrant that the Service will be uninterrupted, error-free, or that AI output will be accurate or complete
  • We shall not be liable for any indirect, incidental, consequential, or special loss arising from your use of the Service, including any loss arising from a rejected or incorrect HMRC VAT claim
  • Our total liability to you for any claim shall not exceed the amount you have paid to us in the 12 months preceding the claim

Nothing in these Terms limits liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation.

10. Termination

You may delete your account at any time from Account Settings. We may suspend or terminate your access if you breach these Terms, with or without notice depending on the severity of the breach.

On termination, your right to use the Service ceases. Sections 6, 7, 8, 9, and 11 survive termination.

11. Governing law and disputes

These Terms are governed by the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.

If you have a complaint, please contact us at support@vatbuild.co.uk in the first instance. We aim to resolve all disputes informally and promptly.
