UK Real Estate Landlord Mobile Number Leads Needed

I need a steady, reliable stream of fresh mobile numbers for London-based landlords and property investors who are open to selling or renting out their properties. I will handle all outreach myself; this job is strictly about sourcing and cleaning the data.

Quality requirements
• Only genuine decision-makers (no letting agents or generic office numbers).
• Every record must be screened against both TPS and CTPS before it reaches me—no exceptions.
• No duplicates, inactive numbers, or data older than 30 days.

Deliverable
A spreadsheet (Excel or Google Sheets) supplied on an ongoing basis, showing at least:
– Mobile number
- Full name and email address as well as company name
– London borough or postcode

What to include in your proposal
1. The data sources you typically rely on (online databases, agencies, social platforms, etc.).
2. How you verify accuracy and perform the TPS/CTPS check.
3. The volume of new leads you can provide each week and your turnaround time.
4. Best price for the work
