Most of the businesses we've been working with have been changing their labels inside their normal cycle of label changes. Most of the sorts of products that we've been talking about for front-of-pack labelling are relabelled very frequently in any case in order to keep the packaging looking fresh and exciting for consumers.
This, again, is another advantage of having a voluntary approach. It allows businesses to make changes within their normal labelling cycling changes rather than requiring them to take on additional cost.
