Green Home
A remote survey product that lets heat pump installers quote with less time on the road, and homeowners get started from their phone.
The problem
A heat pump quote usually needs a site visit, hours of measurements and a stack of forms before the installer knows if the job is worth taking.
What we built
A phone survey that collects what the installer needs, then does the calculations and paperwork automatically.
Features
Phone-first survey
Homeowners answer a short survey and upload guided photos. Email and mobile are verified, and photos are checked for quality.
Property data
The address is matched against the official EPC register, with uncertain matches rejected rather than guessed.
Heat loss
Room-by-room heat loss and a radiator check, worked out before anyone visits.
Paperwork
DNO notification, Boiler Upgrade Scheme details and the MCS 020(a) noise check are prefilled for the installer.
Energy use
Fuel-bill checks and smart-meter usage files turn into measured yearly use and the coldest-day peak.
Installer booking
Installers accept a job by SMS with one tap, offer visit or video-survey times, and get a calendar file.
Exports
Every survey pack downloads as PDF, CSV or JSON for the installer’s own systems.
