Test+Build is a digital platform that provides customers with the tools to design their own behavioural science interventions and run their own randomised controlled trials (RCTs). It introduces the user to BIT’s core methodologies and provides materials, videos and guidelines on how to apply some of the key theories underpinning behavioural science to their day-to-day practices.

Test+Build is a largely automated process that brings in support from BIT staff at specific points throughout the project. BIT staff are on hand to design the trial, conduct analysis and provide the final, quality assured report, as well as offer support throughout the process.

We are currently piloting the product in the area of tax collection and will be shortly in charitable giving. To sign up to our pilot or register your interest, please visit at or email us on
