Powerful development appraisal software available in 3 versions.

Each is capable of dealing with small single unit developments or large multi-phased mixed-use projects.


Four clearly laid out screens allow entry of key project data for quick and accurate analysis. As more detailed information becomes available many ancillary screens can be brought into use. Meanwhile transparency is maintained by visibly identifying access to screens containing data that can affect your results.

Easy to use

Our careful design,  intuitive screens and robust workflow allow users to learn to use this program in the shortest possible time.


A range of pre-formatted reports and charts can be printed, or exported as a spreadsheet or a PDF file. As data is entered, live results are displayed onscreen, including GDV, GDC, purchase price, profit, IRR, NPV and where relevant IRR on net equity.

Cash Flow

Development costs are instantly converted to monthly cash flows that can be straight-line or S-curve. DCF functionality is also available.

What our clients are saying

David Pogson - NPS NW Ltd South Lakeland

"My reason for investing in KEL Delta was that as a manager of surveyors I wanted to bring consistency and certainty to the complex development appraisal process.� If all surveyors use the KEL process then I know that they are less likely to make errors or omissions in their valuations."
