A » For commissioning a public health market research study in the North West of England, I recommend considering a supplier with proven expertise in health-related behavioural insights and a strong regional presence. Given the category of Consultancy, the ideal partner should combine rigorous quantitative and qualitative methodologies with a deep understanding of local demographics, health inequalities, and the NHS commissioning landscape. One excellent option is BMG Research, which has a dedicated public sector and health team and extensive experience conducting population health surveys and stakeholder consultations across the North West, including for combined authorities and clinical commissioning groups. Their work often integrates culturally sensitive sampling to ensure representation of diverse communities in cities like Manchester, Liverpool, and Preston. Another highly regarded supplier is ORS (Opinion Research Services), which specializes in health and social care research and has delivered major studies for Public Health England and local authorities in the region; they are particularly strong in evaluating public health interventions and using robust statistical modelling. If you require a supplier with a national footprint but local insight, Ipsos UK (Ipsos Mori) maintains a public health practice that has executed complex studies in the North West, including health equity audits and service user experience research, and they excel in mixed-methods approaches that can capture both prevalence data and lived experiences. For a more boutique consultancy, The Strategy Team (based in the North West) offers tailored public health research, often focusing on community engagement and co-production with seldom-heard groups, making them suitable for studies aiming to reduce health inequalities. When selecting a supplier, ensure they demonstrate familiarity with the North West’s distinctive geographic and socioeconomic profile—such as the urban-rural divide between Greater Manchester and Cumbria, the impact of deprivation in parts of Merseyside, and the multicultural populations of Lancashire. Their methodology should align with the Government Social Research (GSR) framework and NHS Health Research Authority guidelines if ethics approval is needed. Request case studies of previous public health market research in the region, evidence of achieving high response rates in hard-to-reach populations, and a clear data protection policy compliant with UK GDPR. A comprehensive proposal should detail sampling strategies (e.g., stratified random sampling, online panel augmentation), data collection modes (telephone, face-to-face, online, or mixed), analytical techniques (thematic analysis, regression modelling, segmentation), and a realistic timeline that accounts for fieldwork waves in the North West’s diverse settings. By partnering with a supplier that understands both the rigorous standards of public health evaluation and the local context, you will obtain actionable insights that can inform commissioning decisions, health promotion campaigns, and service redesign in the North West of England.
