Know the planning risks

Article 4 directions, conservation areas, and flood risk flagged before you bid. The constraints that kill deals — surfaced upfront.

How planning flags work

Why developers switch

The old way costs more than the deal does.

Most developers run feasibility in a spreadsheet and pay a QS to sense-check it. Here's what each step quietly costs.

Today

Building the deal in Excel from scratch

Why it costs you

45–90 minutes per deal. SDLT silently wrong after every Budget.

What changes

SDLT auto-applied with surcharges. Rightmove URL in, numbers out.

Today

Paying a QS to confirm the build cost

Why it costs you

£2,000–£5,000 per project — on a deal you haven't won yet.

What changes

28 trades, RICS-benchmarked, regional multiplier baked in. £0 to screen.

Today

Checking flood risk and planning flags manually

Why it costs you

Three tabs open, no single view.

What changes

Postcode in, Article 4 flags, conservation areas, and flood risk surfaced in one view.

Today

Sending a half-built model to a JV partner

Why it costs you

Weeks of back-and-forth on assumptions nobody wrote down.

What changes

Save a feasibility draft, share the link. One version of truth.
