AI-powered evidence checking: 5 UK assessment strands

Photographic evidence, checked by AI before you submit.

SitePhoto analyses your site photos against UK energy assessment and building regulation evidence requirements (Part L, DEA, NDEA, DEC, and ACR) so assessors and builders catch problems before submission, not after. Aligned with EASOB Minimum Evidence Requirements v1 (September 2026).
