Supply Chain Advice Pack: Pre-Installation Building Inspection

A Pre-installation Building Inspection (PIBI) is a mandatory step that should take place before any work begins on a PAS2035-compliant retrofit project. It is an on-site or remote inspection, which ensures that the property is suitable for the proposed energy efficiency measures and that risks are managed effectively.
