A Customer Relationship Management (CRM) system is only as good as the data inside it. Over time, databases decay or become "flat"—containing thousands of names but no actionable insight. LeadCheck breathes new life into your existing records by appending over 15 distinct property and financial data points to every address.
By filtering your list based on Household Income and Property Valuation, you can stop wasting budget on prospects who cannot afford your premium services. Sending a high-end brochure to a household with an income of £62,000 yields a far better return than a "spray and pray" approach targeting an entire postcode sector indiscriminately.
For industries like Home Improvements, Solar, and Mortgage Lending, knowing the Tenure (Freehold vs Leasehold, Owner vs Renter) is critical. Our system allows you to flag and remove "Private Renters" or "Social Housing" tenants from your campaign before you spend a penny on postage or dialler minutes.
You do not need a development team to use LeadCheck. Our platform accepts standard CSV or Excel uploads. Simply export your list from Salesforce, HubSpot, or Excel, upload it to our secure portal, and we will return the file with the new columns appended within minutes.
