Terms of Service
Last updated: September 2026
These terms govern your use of Part L Checker. By creating an account or using the service, you agree to them.
Your account
You are responsible for keeping your account credentials secure and for all activity under your account. You agree to provide accurate information and to use the service only for lawful building compliance purposes.
Assessments are guidance only
The compliance assessments produced by Part L Checker are generated by AI and are provided to help you prepare evidence before submission. They do not constitute official building control approval and are not a substitute for determination by your building control body. You remain responsible for the accuracy and adequacy of the evidence you submit.
Acceptable use
You agree not to misuse the service, to upload only photographs you have the right to upload, and not to attempt to disrupt or gain unauthorised access to the service or its data.
Submissions to third parties
When you choose to send images to appb.co.uk, that submission is subject to the terms of your building control provider. We are not responsible for how a third-party provider handles your submission after it is sent.
Limitation of liability
The service is provided "as is" without warranties of any kind. To the fullest extent permitted by law, we are not liable for indirect or consequential losses arising from your use of the service or reliance on its assessments.
Changes
We may update these terms as the service evolves. Continued use after changes constitutes acceptance. If you have questions about these terms, contact us through our Contact page.
