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).

Find out the benefits of testing your communications. How effective are they and how can they be improved using insights from behavioural science?
TEST + Build helps its users in two ways. First, TEST + Build provides you with insights from the behavioural science literature that you can use to improve your letters, texts, and emails. Second, it shows how you can test these ideas in practice by running ‘randomised controlled trials'. These trials enable you to discover which letter, text message, or email works best. You can then use the results from these trials to make improvements to your communications over time.
