Generic marketing lists are wasteful. Marketing to households that lack the financial capacity to purchase high-ticket items is an inefficient allocation of budget. LeadCheck provides the granular financial intelligence required to filter your lists by Affordability and Asset Value.
By overlaying Area Income Data onto your existing lead lists, you can prioritize leads that actually convert. For industries like Solar, Heat Pumps, and Home Improvements, targeting postcodes with an average household income above £45,000 significantly increases ROI.
Understand the financial footing of a household instantly. Our data models reveal the asset value and sales history of a property. A prospect residing in an owner-occupied property with a Valuation of £650k represents a fundamentally different opportunity than one in a low-value rental sector.
We aggregate data from the Office for National Statistics (ONS), HM Land Registry, and Energy Performance Certificate (EPC) registers. This multi-source verification allows us to model the Average Household Income and Demographic Profile with high statistical confidence.
