Evidence & documentation

What helps on the day, what we photograph, and where to find the right guide.

This page is intentionally “trust‑safe”: we don’t claim certifications we don’t hold, and we only state what we actually do on site.

Survey day checklist Request availability

Evidence timing: relevant documents are photographed during the site visit (when applicable) for RdSAP audit evidence.

On site

What we capture (evidence‑led)

We capture photos, measurements, and notes so the next person can act without re‑questions.

Documents photographed on the day

If you have EPC/insulation/window/building regs paperwork, have it ready during the visit — photos of documents are fine.

Electrical

Electrical evidence (where relevant)

Clear photos + labels reduce guesswork through design, QC, and install.
