Managing large datasets of UK residential addresses can be challenging. Whether you have a list of past leads, a purchased marketing database, or a CRM full of cold contacts, the lack of specific property data makes segmentation impossible. LeadCheck fixes this by allowing you to upload your raw data (CSV or Excel) and download it with over 15 rich data points appended to every row.
Understanding the financial profile of a household is key to selling high-ticket items like Solar PV, Heat Pumps, or Home Improvements. We provide an estimated Valuation based on local market trends and specific Sales History (e.g., "Sold £120,000 on 2006-11-07"). This allows you to identify homeowners with significant equity and long-term ownership, who are often more likely to invest in property upgrades.
We append demographic tags such as "Industry Associations", "Retired Communities", or "Young Families" based on postcode-level census data. Combined with the Household Income estimate, this gives you a 360-degree view of the customer before you even make contact. This ensures your sales team tailors their pitch to the specific financial situation of the household.
For high-volume lead generators, our REST API allows for real-time enrichment. As soon as a lead hits your landing page, you can pass the postcode to us and receive the full property profile in milliseconds. This enables dynamic routing—sending low-income leads to ECO4 teams and high-income leads to private sales teams instantly.
For Bulk CSV uploads, we return a downloadable CSV with new columns appended. For API, we return JSON.
The valuation is an Automated Valuation Model (AVM) estimate based on the last sold price and local market index trends.
