The survey will give the GCA insight into how the 10 regulated retailers are complying with the Groceries Supply Code of Practice, enabling Tacon to focus her attention most effctively in the year ahead.
"All the information you provide is treated in strict confidence," the GCA's office said.
"All answers are collated and analysed by YouGov and respondents are not identified to the GCA without their prior consent."
Hosted at yougov.com/gca, the survey is open from today (6 March) to 17 April, with the results presented at the GCA's annual conference in London on 26 June.
Tacon has also announced dates for two meetings at which suppliers can air their Code-related concerns, including on a confidential one-to-one basis. These are on 27 March in London and on 4 April in Manchester. See the GCA website for details and registration.
