Loft Conversion Leads in London: How to Find and Win Them

11/08/2025

London has one of the highest volumes of loft conversions in the UK. With property prices at a premium, homeowners are increasingly extending upwards instead of moving. This means a steady flow of loft conversion projects—if you know where to find them.

The fastest and most reliable source of loft conversion leads in London is planning application data. Every time a homeowner applies for planning permission for a loft conversion, their details are published by the local council. These are warm leads—people actively preparing to hire trades.

With BuildAlert, you can instantly filter planning applications across the entire UK to show only Loft Conversions. You can narrow results by location or radius, so if you only work in specific London boroughs—or you want to cover multiple areas—you see exactly the jobs that matter. Then, you can use our built-in outreach tools to send branded letters and win the work before competitors even know about it.

Real Example: London Loft Conversion Win

A South London builder using BuildAlert spotted a loft conversion application in Streatham. They sent a letter within two days of the application being published and secured a site visit before any other trades contacted the homeowner.
