Why Planning Applications Are a Goldmine for Builders in 2025
03/09/2025
Every planning application signals serious intent. The homeowner has paid an architect, committed to a design, and staked money on council fees. By the time they hit “submit”, they’re primed to spend tens of thousands—extensions alone average £60–£80k in the UK. That’s why for builders in 2025, planning data isn’t just admin—it’s a goldmine of high-intent, high-value leads.
Unlike cold leads, planning applications reveal three crucial things at once: budget (projects often £30k–£100k+), timing (works likely within 6–12 months), and scope (drawings outline the job in detail). Better yet, most projects spark extra work—rear extensions lead to kitchens and patios, loft conversions to bathrooms, landscaping, or rewires. One job often becomes three.
The catch? Each council publishes applications differently. “Rear extension” in one borough might be “single-storey addition” elsewhere. Finding and tracking them manually means hours of trawling inconsistent portals—time most builders don’t have.
That’s where BuildAlert comes in. Instead of checking 300+ council websites, you log in once, filter live applications by keyword or tag, set your radius, and send a branded letter for £2—all in minutes.

Why Early Contact Wins in 2025
By the time planning approval lands, homeowners start shortlisting. If your name arrives first—letter in hand with proof of similar jobs—you’re in pole position. Builders who act at application stage win more work than those who wait until “approved” status or rely on word of mouth alone.

FAQs
1) Why are planning applications such high-quality leads?
Because they prove intent—homeowners have already paid for designs and fees. That makes them far warmer than online enquiries or cold ads. Start here: See local leads.
2) Do I need planning knowledge before quoting?
At minimum, skim national guidance via the Planning Portal. Then check project-specific conditions in the council’s portal. This ensures your quotes are realistic and compliant.
3) What’s the best timing for first contact?
Don’t wait for “approved” status—by then competition heats up. Contact at submission stage with a branded letter via BuildAlert for £2, then follow up within a week.
4) How do I price these jobs without overcommitting?
Use past case studies and comparable builds to frame realistic ranges. For industry benchmarks, see the Federation of Master Builders for guidance.
