JLL has established a business management system, documented and maintained in accordance with the requirements of the International Standard for Quality Management Systems – ISO 9001:2015. We have been certified by external accredited quality assessors as having satisfied the requirements of the standard since May 1996.
Our certificate for ISO 9001:2015 shows that we are a company committed to quality and that everyone in JLL follows procedures and delivers service to the highest standards. JLL is continually improving the effectiveness and efficiency of our performance by considering the needs of interested parties, particularly clients.
ISO 9001:2015 is based on eight management principles: customer focus, leadership, involvement of people, process approach, system approach to management, continual improvement, factual approach to decision making and mutually beneficial supplier relationships.
The approach of this standard is in line with changes and developments within JLL. We have introduced Client Plus as our client relationship management system and individual performance management as part of a total performance management programme. Underlying this management programme are our values: we believe in ethics, excellence and teamwork. bel
In drawing together ISO 9001 and our total performance management we have developed our business management system; this incorporates what was our quality management system. This is what ISO 9001:2015 covers; we now have a management system that reflects the way we do our business, making JLL more efficient, effective and professional. Our objectives include customer focus, customer satisfaction and continuous improvement.
Commercial Lease Code of Practice
The Code of Practice for Commercial Leases in England and Wales provides a recommended example of good practice in landlord and tenant negotiations over a lease. Use of the Code is voluntary. However, the Government has indicated that if it is not adopted by property companies it will seek to regulate the industry instead through legislation.
