HCA Development Appraisal Tool

Homes England (previously the Homes and Communities Agency) publishes a widely-used Development Appraisal Tool (DAT) for small and medium to medium/large projects with a development period of up to 15 years.

The bid comparator can be used to compare a number of different submissions.

In London, the Greater London Authority (GLA) Affordable Housing Development Control Toolkit is also available, and there are a number of commercially available viability testing tools.
