As part of the restructure, managing director Nick Ramsden has been promoted to the role of group managing director, while sales director Craig O'Connor replaces Ramsden as MD.
In his new role O'Connor will take on overall responsibility for the cash and carry and delivered arms of the business, as well as building on Dee Bee's growing retailer symbol group.
O'Connor will also work on the implementation of the company's new EPoS system ReScan at its fascia stores. Dee Bee said the new system would become part of the support package offered by the company when refits and fascia implementations take place.
Rodney Hunt, Today's Group MD, said: "Congratulations to both Craig and Nick on their new roles. They are a solid team and I'm sure they will continue to innovate."
