The new hire depot is in Borough Green, near Sevenoaks. It is Star Platforms' second depot since launching near Luton, Bedfordshire in October 2014.
Joint managing director Richard Miller said: "Demand for our hire service is strong, so we are delighted to now provide our customers with coverage right across London and the southeast via two depots either side of London. As members of the national hire group The Access Alliance we are also well placed to deliver platforms throughout the UK."
Co-owner and sales director Bryan Freeman, who will oversee operations at the depot, said: "We have already added a number of brand new, market leading machines at the new Kent depot and have also invested in our own delivery vehicles with experienced, IPAF-trained drivers."
Star Platforms is co-owned by Steve Simmons, Richard Miller and Bryan Freeman, all veterans of the powered access industry.
