Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what total reduction in government spending has been attributed to policies drawn up by the Behavioural Insights Team since 2010.

The Behavioural Insights Team (BIT) does not track the cumulative impact of all its work over time, only some of which focus on reducing spending or increasing revenue collection.

However, BIT has now run some 350 trials, each of which shows the impact of different policy interventions in different contexts. These show that the team has helped to save or bring forward hundreds of millions of pounds of revenue and has made efficiency improvements in many different areas of UK Government policy.

This includes:

-changing the messages in letters from HMRC to late tax payers was part of a group of trials that helped bring forward more than £200m of late tax debts;

-changing the messages in letters sent by Local Authorities to late payers of Council Tax is estimated to bring forward an extra £3m in one local authority alone;

-changing the way that Jobcentres support people back to work has been rolled out to some 25,000 Job Advisors and is expected to help hundreds of thousands of people back to work faster.

-informing GPs who overprescribe antibiotics that most practices prescribe fewer antibiotics than theirs reduces the number of unnecessary prescriptions by around 150,000 per year; and

-working with HMCTS to send personalised text messages to people who were delinquent in their court fines. This intervention, which significantly increased payment rates prior to a bailiff intervention, could raise £860,000 per week if rolled out nationally and prevent up to 150,000 bailiff interventions per year.

BIT also works with governments around the world and is seeing similar effects in its work in Australia, Singapore and with cities across the USA.

These findings, and many others, are published once a year in BIT’s Update Report. The next edition of this is due later this month [September 2016].
