What our clients say

Zachary Kingston, Head of Strategy

'We have been really impressed by the research work done with the Behaviour Change Agency to date. Their desktop research has been thorough and of a high quality, yielding behavioural insights that have proven to be enlightening to the business. In addition to the desktop research, BCA has also completed primary research for SAB. This research was conceptualised, designed and carried out to a high standard and yielded results and recommendations which could easily be translated for business purposes. Their commitment to addressing social issues by developing evidence-based solutions is highly commendable.'

'BCA has been instrumental in using behavioural communications to raise our digital profile in order to inform the public and key stakeholders about our activities, as well as mobilise access to educational opportunities for the youth of Mitchell's Plain and surrounds. As a public benefit organisation, it was critically important for us to partner with an agency capable of delivering expert guidance and excellent quality within exacting budgets.'

Dr Lungi Nyathi, Managing Executive

'We have found BCA to be an agency with a proven track record of developing digital campaigns and solutions that actually deliver meaningful results in shifting behaviour within complex and multi-dimensional areas, hence drawing them in again in an area such as mental health.'

The Real Opportunities for Empowering People through Behavioral Science

This article is part of a series based on “A Manifesto for Applying Behavioral Science” from the Behavioural Insights Team.
