Why Data Enrichment is Critical for Retrofit

In the UK retrofit market, simply having a name and an address is no longer enough. With tight margins on ECO4 and GBIS installations, sending a surveyor to a property that turns out to be ineligible is a costly mistake. LeadCheck solves this by appending critical technical data to your leads before you pick up the phone.

1. Verify Tenure Instantly

The single biggest reason for ECO4 lead rejection is tenure. Social housing and private rentals often require complex permissions or differ in funding eligibility compared to owner-occupied homes. Our system checks the Land Registry data to confirm if a property is Freehold and Owner-Occupied, allowing you to prioritize the "easy wins" over complex rental permissions.

2. Size Your Systems Remotely

We don't just tell you the EPC rating. We provide the Total Floor Area (m²) and the Built Date range (e.g., 1967-1975). This data is vital for heat pump installers who need to perform initial heat loss calculations. Knowing the age of the property helps you estimate wall construction type (Solid vs Cavity) before you even visit, ensuring your sales team pitches the correct measures.

3. Target Specific Recommendations

Our API scans the specific "Recommendations" section of the lodged EPC certificate. If you are a Solar installer, you can instantly see if "Solar Photovoltaic Panels" are a recommended upgrade. If you do Insulation, you can check for "Floor Insulation" or "Internal Wall Insulation". This allows you to route leads to the correct department automatically.
