One of the most important reasons for selecting public private partnerships (PPP) as a procurement method for infrastructure projects, is the ability to deliver the best value for money (VFM) under certain conditions. Several studies have identified and analysed the factors that contribute the value for money creation, and others have identified the most viable project success evaluation criteria. This paper aims to empirically examine the relationship between the PPP project ex-post performance and the value for money creation factors. 92 PPP experts from the UK and the UAE participated in this research via an online questionnaire. The questionnaire consisted of VFM factors, PPP performance indicators and several demographic questions. It was found, through the Pearson Correlation Coefficient and Regression analyses, that there was a significant and positive relationship between improved facilities factor to the users and time, quality, economic benefits and scope variation performance of PPP projects. The results of the analysis also showed clear output specification and early service delivery factors contribute only to the performance in terms of service and cost. Interestingly, the results of the analysis showed that optimisation of assets efficiency factor contributed negatively to the scope of variation of projects. The research also, through the regression analysis, showed that sector, experience and job position have no mediating role between PPP ex-post performance and VFM factors. This study confirmed the need for strict criteria in order to describe the achievement of success in PPP projects. These criteria ensure that the actual practice can be measured against the criteria which are set at the start of the project. This paper expanded empirically on the current literature on the relationship between the VFM and PPP project performance (specifically the ex-post performance).
