The group’s guidelines, which are now at version seven and three respectively, also come with posters that can be printed and displayed for the public.
The posters highlight the shift in responsibility for retailers to act in the way they see fit, with one featuring face coverings and the other not.
Ben Massey, director of marketing at the NAJ, said: “The feedback from members is that over the coming weeks and months, members will gradually move from step three restrictions to step four in consultation with their staff teams.
“The shop sensitively posters have been produced for members to give customers peace of mind that members are providing a responsible shopping environment.”
Anna Blackburn, managing director at Beaverbrooks the Jeweller, added: “Following the Government’s announcement regarding the relaxation of Covid measures we’ll be retaining the measures we currently have in place.
“Our preference will be for customers to wear masks, but we won’t enforce this. We’ll continue to monitor the situation and listen to feedback from our colleagues and customers; any relaxation of safety measures will be gradual.”
