What PropertyLord AI does
No spreadsheet. No QS quote. No three tabs open across planning portals.
Postcode in, SDLT and build cost out. A 28-trade model, RICS-benchmarked across 11 UK regions. No spreadsheet, no QS quote.
Try Quick Check freePaste a Rightmove URL. Pull from Allsop, SDL, Savills, Barnard Marcus. Forward an agent's off-market deck. Same check, same report.
See the sources we coverArticle 4 directions, conservation areas and flood risk surfaced against your postcode. The constraints that kill deals, before the viewing.
How planning flags workSold prices from the same street, refined for type, condition and sqft. The GDV your lender will accept, not the one your spreadsheet wants.
How comparables workWhy developers switch
Most developers run feasibility in a spreadsheet and pay a QS to sense-check it. Here is what each step quietly costs.
45 to 90 minutes per deal. SDLT silently wrong after every Budget.
SDLT auto-applied with surcharges. Rightmove URL in, numbers out.
£2,000 to £5,000 per project, on a deal you have not won yet.
28 trades, RICS-benchmarked, regional multiplier baked in. £0 to screen.
Three tabs open, no single view. The risk you miss kills the deal.
Article 4, conservation areas and flood risk surfaced in one view.
Weeks of back-and-forth on assumptions nobody wrote down.
Save a feasibility draft, share the link. One version of the truth.
Try the live engine
These three are starting points, not case studies. Every figure on the report is computed live when you run the check, and you can swap in any UK postcode or Rightmove URL.

A quantity surveyor charges £2,000-£5,000 per project. The investment in PropertyLord AI Pro is about £21 a month on the annual rate, or £29 a month if you'd rather not commit to a year. One unlocked feasibility covers the year.
