Integration
ISO 9001 + ISO 14001 is the most common integrated management system combination in Australia. Both use the same Annex SL structure — context, leadership, planning, support, and improvement are all shared. A combined audit typically costs 25–35% less than two separate audits. Most certification bodies offer joint surveillance.

FAQ
Answers to the most common questions about choosing between these two standards.
ISO 9001 addresses quality management — delivering consistent products and services. ISO 14001 addresses environmental management — reducing environmental impact and meeting legal obligations. These are the two most commonly integrated standards globally.
It depends on what is driving your certification decision. If customers or procurement are asking for quality assurance, ISO 9001 is typically the answer. If you face obligations around environmental management, ISO 14001 is more relevant. Many businesses start with one and add the second 12–24 months later as requirements evolve.
ISO 9001 + ISO 14001 is the most common integrated management system combination in Australia. Both use the same Annex SL structure — context, leadership, planning, support, and improvement are all shared. A combined audit typically costs 25–35% less than two separate audits. Most certification bodies offer joint surveillance.
Difficulty depends on your starting point. ISO 9001 costs $5,500–$105,000 and takes 3–12 months. ISO 14001 costs $5,000–$85,000 and takes 3–12 months. An organisation with mature quality management practices will find ISO 9001 straightforward, while one with immature environmental management processes will face more work for ISO 14001.
Individually: $5,500–$105,000 for ISO 9001 and $5,000–$85,000 for ISO 14001. With an integrated approach — shared consultant, combined audit cycles — you can typically reduce the total by 20–35%. Getting itemised quotes from providers experienced with integrated management systems is the best way to understand your combined cost.
