Public procurement policy Directives, regulations, policies and guidance relating to the procurement of supplies, services and works for the public sector. From: Contents Print this page As a buyer or commissioner of supplies, services and works for the public sector you need to understand and be able to readily access the regulations and policies relating to procurement. The Crown Commercial Service ( CCS) is responsible for the legal framework for public sector procurement and leads on the development and implementation of procurement policies for government. Introduction The over-riding procurement policy requirement is that all public procurement must be based on value for money, defined as “the best mix of quality and effectiveness for the least outlay over the period of use of the goods or services bought”. This should be achieved through competition, unless there are compelling reasons to the contrary.
