Reach the home before the welcome pack.
New-occupancy signals, property-level EPC and fabric data, and tariff-fit intelligence — for any UK address, refreshed daily. Propalt gives utility acquisition, network planning, and retention teams the property-signal data behind sharper targeting and smarter tariff matching.
The Problem We Solve
Utility relationships are won and lost in the days around someone moving home. Yet most acquisition teams find out a property changed hands weeks late — by which point a competitor's welcome pack is already on the kitchen counter. Tariff matching is postcode-level, ignoring the property's actual energy profile. Network planners build capacity on Census data older than the streets they're servicing.
The Propalt API gives utility acquisition, retention, and network-planning teams occupancy-change signals at the property level, EPC and fabric data including heating type and main fuel, heat-pump and EV-charger suitability indicators, area-level fuel-poverty and vulnerability signals, and longitudinal property-stock data for capacity planning — at the property and area level, with no personal data. Reach the right home with the right tariff.
What You Can Build
Six common patterns built on Propalt by utility acquisition, retention, and network-planning teams today — all from property-level and area-level signal data, never personal contact data.
Property-level occupancy-change signals
Identify addresses that have just changed hands — surfaced daily, weeks before the new resident appears on the electoral roll. Feed into your own compliant new-mover acquisition campaigns.
Property-level tariff personalisation
Match every property to the right tariff product using EPC band, main heating fuel, fabric, and floor area — plus owner-vs-let routing via audience-letting-property and broadband availability via get-broadband-data for fixed-line and altnet matching. Move tariff quotes from postcode-average to property-specific.
Heat-pump and clean-heat suitability
Score every UK property for heat-pump suitability using EPC fabric data, current heating fuel, and floor area. Target installer partnerships and clean-heat tariffs at the homes that can actually take them.
EV-charger suitability and EV tariff fit
Surface properties with off-street parking signals and suitable electricity supply for home EV charging. Match to EV tariff products at acquisition.
Property-stock data for network planning
Quantify EPC-band distribution, fabric profile, and heating-fuel mix across any postcode, district, or DNO area. Feed long-term electrification and heat-pump capacity planning with current data, not Census-era estimates.
Area-level fuel-poverty risk signals
Identify postcodes and LSOAs with high concentrations of low-EPC properties and low-income demographics — backed by get-income at LSOA level — to support Priority Services Register outreach planning. Area-level only — for use with the utility's own existing customer database and consent records.
