Supplier selection is an essential part of business activity in the supply chain. As the supply chains become increasingly globalised, supplier selection requires an understanding of cross-cultural differences in decision-making.The main objectives of the research were to investigate the levels of importance attributed to 44 selection criteria and sub-criteria in the research framework. It aimed to reveal differences in supplier selection between two cultural groups, the UK, and the UAE to examine the key supplier selection criteria from the construction industry. It aimed to develop a mathematical model for the supplier selection process that can be employed in the construction industry to address gaps in previous studies. The results reveal that the most important criteria are financial position and quality management system, the results showed that there were similarities in green practices and supplier logistics and significant differences between the UK and UAE in terms of the importance of selection criteria. The results show that the cultural attributes of suppliers were the least important criteria compared with the other criteria available in the current research framework
