The rebrand has seen changes to all signs and information screens at the Avanti West Coast-managed station.
“A whole new town, a whole new name, just to welcome Scott Mills,” the station spokeswoman said.
The 51-year-old has taken over from Zoe Ball, who announced in November last year that she was stepping down to “focus on family”, having replaced Chris Evans in the slot in 2019.
As she sanctioned the name change, the mayor of Stockport Suzanne Wyatt told Mills on air: “I’m very happy. I think it makes people smile. The more we can do to make people smile, the better.”
Alongside the changes at the station, the bridge over the M3 at Fleet Services was also renamed for the day.
