This calculator is an indicative financial screening tool based on assumptions you enter. It is separate from, and does not influence, the Planning Opportunity Score elsewhere in this report. It is not a RICS red book valuation or formal viability appraisal and should not be relied upon without professional advice.
This assessment is an automated planning intelligence report based on available public data. It does not constitute planning, legal, valuation or other professional advice and does not guarantee that planning permission will be granted.
