The FSA wanted to explore compliance levels with FHRS, by measuring how many businesses display their rating, exploring the reasons and drivers for display and non-display, and more broadly explore food businesses’ awareness and attitudes towards the FHRS. A key challenge, when developing a methodology that captures compliance levels, is mitigating against any social desirability bias, where respondents may state that they meet regulatory requirements when the reality could be different. Alongside self-reported measures, the project included a physical audit of premises to visually check if and how the ratings are displayed.
