ASSESSMENT TRANSPARENCY
How QuoteGuardian Assessments Work
QuoteGuardian turns confirmed quotation details into a structured second opinion. It does not decide whether an installer is trustworthy or replace a survey; it exposes omissions, inconsistencies and questions that deserve written answers.

Evidence and confidence
Every finding distinguishes a confirmed fact, a calculation or a broad assumption. Confidence reflects the quality of the evidence, not certainty about future performance.
What the result cannot prove
- Installer competence or honesty
- Site-specific engineering suitability
- Actual future savings or energy prices
- The legal effect of contract wording
