Verify before you spend.
Not certification.
See what is known, estimated, and missing — and which high-impact facts to verify next — before upgrades, surveys, or portfolio works. One home free score, or a founder-led rental pilot.
Decision support only — not an EPC certificate, compliance sign-off, or substitute for accredited professionals. Primary commercial path today: a paid, manually supported Portfolio Readiness Pilot for landlords and letting agents — not self-serve multi-home SaaS. You still commission assessors for anything lodgable.
Sample Home Resilience Passport
3 bedrooms · gas boiler · partial loft insulation · smart meter unknown
Sample demo — not your home — not an Energy Performance Certificate. Estimate only.
Verify loft insulation before sizing a heat pump.
What to verify before spending — not a savings promise.
Promising upgrade candidate, but evidence is not strong enough for expensive decisions yet.
Mock illustration — verify facts before major spend. No savings or flexibility income guarantees.
Passport is the anchor
Start with the free Health Score. Build the Home Resilience Passport as your evidence improves — the single source of truth for your home's facts.
Primary commercial offer
Portfolio Readiness for landlords & letting agents
Start with a five-property feedback diagnostic, or a paid manually supported pilot (25–100 homes): EPC matching, attention bands, evidence checklist, review pack, and one facilitated session. Helps sequence investigation — does not replace a Domestic Energy Assessor or close MEES liability. Indicative pricing — not self-serve multi-home SaaS.
