In 2014 the European Union adopted new procurement Directives for Public sector, Utility sector and Concessions contracts. With the reform of the Directives they hope to achieve better access to public contracts for SMEs. One of the measures set into place to do this is the rule encouraging contracting authorities to split contracts into lots. The Public Contracts Regulations 2015 transposed the 2014 Public Sector Directive in February 2015, and with it the “Split your lots” rule. With this blog I hope to make it a bit more clear what a contracting authority is required to do.
