JJB Sports has agreed a new 15-year lease on the Pentagon Centre in Chatham.
This is the second significant letting at the centre in six months, following the leasing of a 25,000 sq ft unit to New Look, last year.
The sports retailer has bought an anchor store on the first floor, a unit of 15,000 sq ft.
The Pentagon Shopping Centre offers over 70 retailers and has a footfall in excess of 30,000 people each week.
Discussions are underway with Medway Renaissance, a local regeneration partnership, to expand the scheme.
The agents of the Pentagon Centre are Savills.
