Target the homes that can actually take it.
EPC, fabric, tenure, and clean-tech suitability — for any UK address. Propalt gives green-retrofit installers, fabric contractors, and improvement marketplaces the property-signal data behind sharper targeting and higher quote-to-install rates.
The Problem We Solve
Home-improvement marketing burns money on properties that can't take the product. Solar PV quotes go to north-facing terraced roofs. Heat-pump leaflets land on uninsulated solid-wall Victorians. External wall insulation campaigns hit flats. By the time the installer arrives to survey, half the visits are obviously unsuitable — but the conversion data is already spoiled and the marketing report still calls it a "lead".
The Propalt API gives green-retrofit installers, fabric contractors, and improvement marketplaces property-level EPC and fabric data, heat-pump and solar-PV suitability indicators, tenure and owner-type signals, grant-eligibility inputs for ECO4 and Boiler Upgrade Scheme targeting, and postcode-level density mapping — at the property and area layer, with no personal data. Target the homes that can actually take it.
What You Can Build
Six common patterns built on Propalt by green-retrofit, fabric-contractor, and improvement-marketplace engineering teams today — all from property-level and area-level signal data, never personal contact data.
Pre-quote property fit screening
Score every UK address for solar PV, heat-pump, EWI, cavity wall, and loft insulation suitability before the quote is generated. Stop wasting site visits on properties that can't take the product.
ECO4 and BUS eligibility signals
Surface property-level signals that align with ECO4 (low-EPC + LSOA-level income context via get-income) and the Boiler Upgrade Scheme. Pre-qualify properties for grant funding before the installer makes contact.
Owner-occupier vs landlord routing
Identify whether a property is owner-occupied or landlord-owned using ownership and corporate-entity signals — strengthened by audience-letting-property for live let-status detection in addition to audience-landlords. Route to the right sales motion — B2C for homeowners, B2B for landlords with portfolios.
Installer-capacity catchment planning
Map qualifying properties by postcode density — heat-pump-suitable, EWI-suitable, solar-PV-suitable — to schedule installer regions efficiently. Stop overbooking in saturated areas and underserving emerging ones.
Property-fit product matching
Match every property to the most relevant retrofit product based on fabric, EPC, heating fuel, and roof orientation. Solar where it works. EWI where it works. Heat pumps where the fabric supports them.
Compliant marketing inputs
Feed property-level and area-level signal data into the company's own postcode-targeted ad campaigns, TPS-screened outreach, and installer-partner programmes. Targeting at the property layer — individual contact data stays the company's responsibility, sourced through its own compliant channels.
