BuildAlert helps UK tradespeople - roofers, electricians, plumbers, carpenters, plasterers, groundworkers and more - generate high-quality leads from recent UK planning applications. Search projects that match your trade and preferred locations, then send personalised letters or postcards directly to homeowners through the platform. We print, post and track every campaign for you, making it easy to build a consistent pipeline of new work.
Every planning application includes valuable information about the proposed project, and where available you can review the planning drawings before deciding whether it's worth making contact. You can filter by trade and project type, target specific postcodes or custom search areas, and automatically follow up with homeowners using scheduled letter campaigns.
Unlike traditional trade lead generation services that sell shared enquiries, BuildAlert gives you complete control. You decide which homeowners to contact, when to contact them and how often to follow up. There are no subscriptions, no shared leads and no long-term contracts. You simply pay for the letters or postcards you send.

Finding trade leads isn't usually the problem. Finding them before a main contractor has already lined up their own subcontractors is.
Many lead generation companies sell the same enquiry to several tradespeople after the homeowner has already started requesting quotations. That means more competition, lower margins and a race to be the cheapest.
Planning applications work differently. They let you identify homeowners at the start of their journey, often weeks or months before they're ready to appoint a contractor for your specific trade. You can review the application, view planning drawings where available and decide whether the project is worth pursuing before spending a penny on marketing.
The result is better-qualified trade leads, less wasted marketing spend and more opportunities to win the kind of work you actually want.
Traditional trade lead generation services often charge hundreds of pounds every month for shared enquiries, regardless of your trade.
With BuildAlert, you can search every UK planning authority for planning applications matching your trade, then send personalised letters or postcards directly through the platform. Every plan includes nationwide planning application data, with monthly letter credits and lower mailing costs as you grow.
Instead of paying for the same leads as everyone else, you're building your own predictable pipeline of trade opportunities.
Most homeowners don't appoint every trade immediately after submitting a planning application.
Many spend weeks researching contractors, reading reviews, comparing previous work and deciding who to trust for each part of the project.
That's why BuildAlert lets you schedule automatic follow-up letters 7 or 14 days after your first campaign, or automatically when planning permission is approved. Staying in touch throughout the planning process keeps your business front of mind and increases the likelihood of converting planning applications into paying customers.
As a general guide, 1-2% response/conversion is a solid baseline, 2-5% is very good for well-targeted campaigns, and 4-8% is achievable with highly targeted lists, strong offers and consistent volume - tradespeople sending hundreds of personalised letters through BuildAlert have reported results in this range.
The strongest results typically come from businesses that make contact early, have a professional website, excellent customer reviews, competitive pricing and a consistent follow-up process.

Example: BuildAlert highlighting planning applications by trade, postcode and project type
Every trade needs different information from a planning application. Here are the project types most worth targeting for some of the trades BuildAlert supports.
Re-roofs, loft conversions and roof extensions all show up in planning data long before a roofer is booked, giving you time to quote directly to the homeowner.
