The supermarket group has appointed Rebecca Hopper to the position of retail marketing manager at its Rhythm & Booze brand, Emily Lawley as digital executive across all brands and Jennifer Steel as a marketing executive across all brands.
Costcutter's new appointments come as it trademarks the names Minute Mart and Go Shop with the Intellectual Property Office (IPO) under clause 35.
Minute Mart is the name of the shop in 'EastEnders', which has a green-and-white fascia and has been around for years without being trademarked.
The potential to launch brands under the Minute Mart and Go Shop names comes after Costcutter revived the Kwik Save brand at the beginning of the year.
Hopper joins Costcutter from rival operator Today's Group and in her new role, will take responsibility for developing the new look for the revitalised off-licence brand and delivering an integrated marketing strategy to drive customer awareness and footfall.
She will also support the retailer recruitment programme to support the rollout of a "market-leading franchise package".
Lawley joins from Visit Scotland and is tasked with driving forward the business's online activities, including the creation of new brand-specific websites the group's brands and the development of Costcutter’s first mobile phone app, which will be available across Apple and Android platforms.
She will also be in charge of handling social media activity across the business.
Steel joins from E&L Insurance and will provide support across all brands, assisting retailers with store specific marketing activities and wider group initiatives.
Ian Bishop, marketing director for Costcutter Supermarkets Group, said: "These key appointments signal our intent to continue growing the business for the good of all of our retailers.
"We are investing heavily in our digital channels and the creation of brand specific platforms is an integral part of helping our retailers promote themselves and engage with customers."Follow @mattchapmanuk
