The iconic fashion brand, which was founded in 1873, selected B38 following a competitive tender process.
Under the terms of the agreement, the Wakefield-based integrated facilities management company will undertake daily and periodic cleaning, and provide additional soft service support in Russell & Bromley stores and staff breakout areas.
Discussing the award, Russell & Bromley's Head of Retail, Rob Foster, said:
"We were very impressed with the B38 Support Services management team, their knowledge, enthusiasm and energy convinced us that they were a good cultural fit and people we could work with.
"Russell & Bromley is a quality brand with a long tradition of customer care and it’s important to us that our customers enjoy the best possible shopping experience, and this includes ensuring that our stores are presented to the highest standards.
"As a national provider with experience in luxury retail, B38 Support Services ticked all of the boxes. We liked the fact that they had effective systems in place but were continuing to innovate and grow. We also appreciated their positive, inclusive and respectful approach to all members of their team."
Stephen Trott, who leads B38 Group's support services division, said:
"We believe we secured the successful bid simply because we were the right company, able to do the right job at the right price. It’s fantastic news that we have won this prestigious contract and have been trusted by one of the best-known, quality brands on the High Street."
