How Compare Builders works.
Three steps. Start your project in two minutes. We match you with verified builders — you choose who quotes. Never a flood of cold calls.
Tell us about your job
Start your project in two minutes. Ten short screens: your details, project type, budget bracket, timeline, location. We verify your mobile — no junk gets through.
We match verified builders
Local verified builders put themselves forward for your project. We rank them on verification, reviews and track record — and it's free for homeowners.
You choose who quotes
Pick up to three builders to quote, compare them side by side, and appoint the one you want. Only your appointed builder ever sees your contact details — publicly verifiable by their CB-XXXXX number.
Your journey
Ten funnel screens plus the supporting flows around them.
Your details
Name, email and mobile first — your progress saves, and only the builder you appoint ever sees them.
Project type
Sixteen trades — from extensions, lofts and renovations to plumbing, roofing, flooring and driveways. One tap.
Project specifics
Sub-type and approximate size. Slider, not a free-text field — exact numbers aren’t useful at this stage.
Project status
Where the project is right now — ideas, drawings, structurals, planning. The biggest predictor of a smooth project.
Budget bracket
Pick a band. Builders quote the project, not the band — exact figures aren’t useful at this stage.
Timeline
ASAP through to just exploring. The ‘just exploring’ route is honest — useful planning info, not a hot-lead push.
Location
Your postcode drives the match radius. Builders see your area only — we don’t share your address until you appoint one.
Invite builders (optional)
Already know a local builder you rate? Look them up and invite them to quote alongside the builders we match.
Photos & plans (optional)
Site photos, floor plans, architect drawings — anything that helps a builder quote accurately. Skip if you’d rather not.
Review, verify & consent
Check your summary, give GDPR consent and confirm your email and mobile with short codes — mandatory before matching begins.
Holding page (submitted)
Project summary, what happens next, optional add-ons. Your matched builders appear in your account for you to choose from.
What happens behind the scenes
The bit that’s invisible to you, but does the heavy lifting on trust and quality.
Matching
Verified builders are invited by trade and postcode, ranked on verification, reviews and track record — never on who pays most.
Shortlist
Interested builders put themselves forward. We surface the strongest and you pick up to three to quote — transparently, with each builder’s trust record shown.
Quotes & appointment
Your chosen builders quote through the platform. You appoint the one you want — contact details are exchanged then, and never before.
