The new hire depot is in Coalville, Leicestershire, and will serve the East Midlands region.
Star Platforms opened its first depot in Luton in October 2014. A second, in Wrotham, Kent, started up in August 2015
Joint managing director Richard Miller said: "Our aim is to combine the latest, most modern powered access machines with excellent customer service and support. Our success with this approach has allowed us to take advantage of the availability of a large and modern depot in a location that is perfectly placed to give our growing number of customers the best possible service.
"Our vision for providing excellent service tailored to customer needs, has helped us to recruit a strong team, with good experience in the powered access industry, and the focus on customer service we want. As members of the national hire group The Access Alliance we are also well placed to deliver platforms throughout the UK."
Star Platforms is co-owned by Steve Simmons, Richard Miller and Bryan Freeman, all veterans of the powered access industry. It operates a fleet of scissors, booms and low-level equipment, tracked mounted booms and vehicle-mounted platforms up to 22-metres working height.
