Important Compliance & Liability Disclaimer
This software is provided for guidance and preliminary planning purposes only. The Light Reflectance Values (LRVs) used in this tool are sourced from third-party manufacturers; we cannot guarantee the accuracy of external data or consistency across different production batches.
While this tool applies the calculation logic set out in Approved Document M (Volume 2) and BS 8300-2:2018, it does not constitute a formal compliance certification, legal advice, or a guarantee of Building Control approval. Real-world visual contrast is heavily influenced by lighting design, material texture, and maintenance, which cannot be fully replicated digitally.
User Responsibility: You are responsible for verifying all specifications against physical samples and seeking approval from a relevant Building Control Body or Access Consultant. The providers of this tool accept no liability for any loss, damage, or compliance failure resulting from the use of, or reliance on, this data.
