WhoBuilt is the UK's first independent quality comparison service for new build housebuilders — combining verified resident reviews, warranty data, and expert build quality scores so buyers finally have the truth.
No spam. Early members get free access to our launch reports.
You're on the list — we'll be in touch before launch.
Aggregated ratings across structural defects, finishing, and snagging — verified against NHBC warranty data.
Post-completion reviews from real homeowners — not purchase-day surveys filled in before the problems appear.
How quickly do builders respond to defects? We track responsiveness across the 2-year liability period.
A builder strong in the South East can be poor in the Midlands. We surface performance by region and development.
Spec vs. price analysis — what's included as standard versus what other builders charge as extras.
Real-world EPC performance and energy bills — not just developer claims about green credentials.
Indicative quality ratings based on publicly available data. Full methodology published at launch.
"Buying a new build is one of the largest financial decisions of your life. You deserve better than a developer's own five-star survey."
