Market research case study:
Behaviourally optimising communications

United Utilities

The challenge

United Utilities (UU) commissioned DJS Research to understand how best to communicate with customers to reduce customer alarm during changes to their water supply. The organisation supplies over seven million people with clean water via 42,000 kilometres of pipes.

For various reasons – including maintenance work and the need to redistribute water across their integrated network during drought or dry periods – UU occasionally supplies customers differently.

On such occasions UU may use and blend water from another treatment works, which processes water from a different source. As a result, some customers across the North West experienced changes in the taste, smell, or appearance of their tap water.

The approach

DJS Research was commissioned to qualitatively co-create the ideal messaging, tailored to specific audiences, with the aim of enhancing customer acceptability of water supply changes.

The project began with a rapid review of the literature, including UU’s past research, to identify recurring themes that could inform the study.

This was followed by a staff workshop designed to educate UU’s design staff on the benefits of behavioural science and enable them to develop iterations of customer communications using key behavioural principles.

These communications were tested with customers through reconvened focus groups and in-depth interviews across the operating region.

The results

The research provided the UU communications team with clear guidelines on content and format changes to reduce customer alarm, as well as recommendations for tailoring communications to different audiences.
