The Field Division are the fieldwork experts at Plus Four:

 "We have worked with Plusfour Market Research for several years. Throughout our relationship, they have always offered a quality and professional service regardless of the project size or budget. One particular benefit of working with Plusfour is the fact that senior personnel are involved with the project from briefing stage, right through to completion (specifically their MD Peter Allan). We feel that this adds real value to the process. They are not frightened to question our approach and frequently suggest alternative methodologies, approaches and ways of working. All of these projects were delivered on time and within budget – and very importantly, within the agreed project criteria (e.g. number of respondents, profiling etc). Reports are well written and presentations are clear and concise. One final point I would make is that Plus Four demonstrate an aptitude of working with a very diverse client base – not just in terms of product sectors but also in terms of cultural differences. This is extremely reassuring when one is dealing with the very specific, and sometime unique, working practices of clients from overseas markets. We would have no hesitation in recommending the people and services of Plus Four to another client" Ad Agency.


"I have been hugely impressed by Plus Four's passion and grasp for the topic, their commitment and efficiency and their attention to detail. Plus Four have offered excellent expert advice and support through the research design stage, professionalism and warmth of fieldwork, and meticulous accuracy and attention to detail in the analysis and reporting. Plus Four's written and verbal presentations of the research findings have been of a high standard. Plus Four have been prepared to go above and beyond to support the business case behind the research." Charity


"It always amazes me how Plus4 delivers and excels, time after time, whatever the project diversity, size or location. I especially appreciate the personal approach, skilful execution and pro-active attitude of Cara and her team, which makes Plus4 such a reliable -and enjoyable- business partner."  Global Manufacturer
