How it works
From planning portal
to paid job
We do the scanning. You do the winning.
01
We find the projects
BuildSignal scans 400+ UK councils every hour. New planning applications are surfaced the moment they're published — before most contractors even see them.
Real-time scanning02
AI scores every lead
Our model scores each lead 0–100 using approval probability, estimated project value from floor plans, Land Registry purchase dates, and local demand signals.
AI enrichment03
You quote before rivals
Send a professional branded letter to the homeowner — at the planning stage, before anyone else is quoting. Our automation sequences do the follow-up for you.
Automated outreachLead intelligence
Every lead, deeply
enriched
We don't just hand you a postcode. Each lead comes pre-enriched with AI signals, Land Registry data, architect track records, and intent triggers — so you know exactly which jobs are worth chasing.
Land Registry timing
House bought 3 months ago + planning application = almost certain hot lead. We layer in purchase dates automatically.
Project value from floor plans
AI reads floor plans and build type to estimate project value using local build-cost data. Know if it's a £5K or £50K job before you write a word.
Approval & distress signals
Just approved is a very different lead from just submitted. We flag approval events and re-submission urgency to time your outreach perfectly.

Supplier intelligence
Not just builders.
Suppliers pay more.
Travis Perkins, Howdens, and tool suppliers have massive marketing budgets — and they want to know where the next 500 extensions are being built.
Materials Intelligence Feed
Suppliers get a live pipeline of planning apps by category and region — 200 rear extensions starting in Birmingham next month means a lot of bricks and cement.

★★★★★
"We use BuildSignal to automatically send branded letters to everyone planning an extension in our area. The Territory Lockout is a game changer — we closed £140K of work last quarter from it alone."

Owen Reed
Builder · Birmingham
★★★★★
"The AI scoring is brilliant. I only chase leads scored 80+. My quote-to-job conversion has tripled because I'm talking to homeowners who've already had planning approved — they're committed."
Mark Hughes
Window Fitter · London
★★★★★
"Most of our work comes from extensions needing bifolds. BuildSignal points us straight to those jobs. We've picked up five installations just from letters — each worth £8–12K to us."
