About Propertoasty

What we do

Propertoasty helps UK homeowners make confident decisions about heat pumps and solar PV. The free 5-minute check takes your address; pulls your EPC, runs Google’s Solar API against your roof, and (optionally) analyses an uploaded floorplan via Anthropic Claude vision. The output is a personalised report covering:

Heat pump suitability + sizing range + BUS grant eligibility
Solar PV system size + expected output + payback
EPC band + recommended improvements + cost ranges
Matched MCS-certified installers covering your postcode

Why we built it

UK homeowners deciding on low-carbon heating face the hardest information-asymmetry problem in the property market. The technologies are unfamiliar (heat pumps), the grants are confusing (BUS, ECO4, GBIS), the installer market is fragmented (5,500+ MCS firms with wildly variable practice), and the cost-of-getting-it- wrong is high (oversized heat pumps cost £1,500/yr more to run than rightsized ones).

Propertoasty exists to compress that information gap into a 5-minute check. We bring three otherwise-siloed datasets together (EPC, solar irradiance, floorplan) and present a single installer-ready report. Installers get qualified leads with property context; homeowners get clarity without an installer sales call.

How we make money

Installers pay a small per-lead fee (~£20-£50) when a homeowner books a meeting with them through Propertoasty. That’s a fraction of what installers spend on traditional lead-gen channels (Google Ads, Checkatrade subscriptions, lead-broker fees), and the leads come with property data attached, so the economics work for them.

Homeowners pay nothing.We don’t sell your data. We never share your contact details with an installer until you explicitly book a meeting.

How we’re different from Checkatrade / MyBuilder / Bark

Traditional directories list traders and let homeowners contact them directly. That’s great for plumbers and electricians where the job spec is obvious — “my boiler is leaking” — but it’s the wrong shape for heat pump and solar installs, where the right answer depends on data the homeowner doesn’t have (heat-loss kW, roof segments, EPC recommendations to clear).

Propertoasty inverts the model: we collect the technical data first, generate a report, and then connect the homeowner to an installer who can see the report on day one. Installers stop spending the first three visits on discovery; homeowners stop wasting visits on the wrong technology. The 5-minute check is the wedge.

The data sources we use

GOV.UK EPC Register. Every certificate lodged in England + Wales. Refreshed monthly. Used for property-level suitability + the quarterly EPC Index research.
Google Solar API. High-resolution roof segmentation, panel placement, annual irradiance. Used to size solar PV systems.
Anthropic Claude vision. Floorplan analysis to estimate room counts, floor area, and heating-load proxies.
MCS-certified register. 5,500+ installer records, monthly refresh from mcscertified.com.
Companies House. Years-in-business signal for installer profiles.
Google Places API. Verified Google reviews for installer cards (refreshed on-demand, 30-day cache).

The people behind Propertoasty
