We import 20,000+ planning applications every week from 400+ UK councils, giving you early access to high-intent construction leads and home improvement projects across the UK.
Browse applications free. When you spot a strong project, send a branded letter or postcard directly from your dashboard in one click(from £1.75) and reach the client before competitors even quote.
Or switch on automation and contact every new matching application automatically.
No shared leads. No bidding against five other builders. No paying for clicks.

See new planning applications near you, automatically tagged by type. Filter by job type, location/radius, and domestic or commercial.
Send branded letters or postcards in one click. We print, post, and track them so you’re first to quote.

Not every homeowner responds to the first letter. With BuildAlert, you can schedule follow-up letters in advance so you stay in front of the client while they’re still planning their project.
Choose when your follow-ups should be sent and select a template. We handle the printing and posting automatically, so you can run consistent outreach without extra work.

Direct mail works. But most of it stops at the letter. A QR code makes the next step simple. The homeowner can call you, visit your website, or save your details in seconds. You see who engaged, and they remember your name.
Most construction companies and property professionals spend money on marketing without clear visibility on what comes back. There’s no structured record of who was contacted, who responded, or what revenue it generated. That uncertainty adds up.
BuildAlert’s lead tracking dashboard gives you control. Every letter you send is recorded. When a homeowner responds, you log it. When you win the job, you enter the value. Over time, you build a clear, accurate view of what your outreach is producing in real revenue.
