Market research case study:
Four-day working week consultation

South Cambridgeshire District Council

The challenge

In January 2023, South Cambridgeshire District Council (SCDC) began piloting a four-day working week for office-based staff, later extending the trial to non-desk employees such as waste collection operatives. Under the model, staff were expected to deliver 100% of their workload in around 80% of their contracted hours, while receiving full pay. The initiative attracted national attention, prompting debate about whether a four-day week could enhance productivity, recruitment, and wellbeing while maintaining high-quality service delivery.

In late 2024, SCDC commissioned DJS Research to conduct an independent programme of consultation and research. The council needed robust, representative evidence on how the trial was perceived by residents, businesses, and stakeholders, both to inform future decisions and to meet statutory 'best value' requirements. The research aimed to: capture public, business, and stakeholder views via an open consultation; deliver statistically robust surveys; and provide findings that could withstand political, public, and media scrutiny.

The approach

Questionnaire design: SCDC drafted an initial questionnaire with external input. DJS Research refined and tested it to ensure clarity, robustness, and comparability across consultation strands. Respondents rated satisfaction with council services before and since the trial and could provide open comments. Additional questions explored awareness of the trial and how a four-day week might influence job attractiveness.

Public consultation: An online consultation ran on the Council’s website from January to March 2025, with tailored versions for SCDC and Cambridge City Council, with whom SCDC shares planning and waste services. Separate routes were designed for residents, businesses, and statutory stakeholders, including Citizens Advice, the Federation of Small Businesses, housing tenant groups, and voluntary organisations, with each audience asked only about relevant services. The consultation received over 1,200 responses, including 1,048 residents, 58 businesses, and 31 stakeholders.

Representative surveys: Two large-scale surveys provided statistically robust evidence. A residents survey conducted 1,047 interviews (847 in South Cambridgeshire, 200 in Cambridge City) via telephone and face-to-face methods to ensure inclusivity. A business survey conducted 400 interviews (319 in South Cambridgeshire, 81 in Cambridge City), with quotas set by business size and sector. Quota sampling and weighting were applied across both surveys to match population profiles by geography, age, gender, disability, and business characteristics.

Analysis: DJS Research applied a rigorous framework. Open comments were analysed using AI-assisted text analytics and refined by experienced coders. Statistical tests, including Wilcoxon signed-rank and chi-squared tests, assessed changes and subgroup differences. Reliability checks ensured findings were accurate and representative. This approach ensured results could inform decision-making and withstand scrutiny.

The results

The programme provided SCDC with a comprehensive, independent evidence base on the four-day working week. The open consultation revealed a wide range of detailed views, including those from external campaigns, while the representative surveys provided statistically robust insights from the wider population.

Stakeholder engagement fulfilled statutory 'best value' duties, ensuring transparency and accountability. Together, these strands enabled SCDC to: compare satisfaction with council services before and after the trial; understand variations across demographics, business size, and sector; and explore broader attitudes toward the four-day week, including its impact on job attractiveness.

The findings gave SCDC clarity and confidence to evaluate the trial and inform future workforce and service decisions.

Reflections: The project highlights DJS Research’s ability to deliver complex public consultations with methodological rigour. Strengths included: a flexible, inclusive approach to survey design and fieldwork; tailored stakeholder engagement; robust analysis combining AI tools with expert oversight; and clear, evidence-based insights to support high-profile decision-making.
