The 3-part system
Score → Incentives → Pathway. No jargon, no guesswork.
Score (0–100)
6 scored areas — envelope, heating, ventilation, hot water, solar, and storage & grid — combined into one clear number. No letter grades; every improvement counts.
Data: EPC records, PVGIS solar estimates, OSM geometry
Incentives & Grants
We surface the rebates and grants that actually apply to your home, filtered by country, region, and property profile. Hundreds to thousands in incentives go unclaimed every year — we help you find them.
UK, Israel, US, AU, FR, NL supported
Upgrade Pathway
A step-by-step plan ranked by ROI, comfort gain, and carbon reduction — with synergy-aware ordering. Insulate before you size a heat pump. Battery before you export. The order matters.
Synergy-optimised • ROI-ranked
Why this isn't another EPC tool
Beyond EPC A
Government ratings stop at A. Our score goes to 100 — rewarding solar generation, battery storage, grid export, and demand response. We score the prosumer future, not just efficiency.
Continuous, not stepped
EPC uses letter bands with cliff edges. We use smooth scoring curves — improving insulation from R-20 to R-30 gradually increases your score based on real physics, not arbitrary thresholds.
Open methodology
Every formula, data source, and weighting is published. No black box. Community-contributed and continuously evolving with peer review.
200+ technologies researched
From ASHP COP curves to MVHR recovery rates — sourced from 478 YouTube videos, 50+ podcast episodes, SAP 10.2, ArXiv, and Google Scholar.
