Practical guidance to help bring unconsented or undocumented
Practical guidance for unconsented or undocumented building work.
Building work completed without consent, missing documentation, or historic alterations can feel overwhelming — but a Certificate of Acceptance (COA) may provide a practical pathway forward.

Whether the work relates to historic alterations, unconsented construction, changes identified during property sales, or projects requiring technical clarification, we help identify what information may be required and support a practical pathway toward compliance.
Our team understands both the technical requirements and the real-world challenges involved in COAs, providing clear advice, practical solutions, and technically robust support throughout the process.
