A ‘framework agreement’ is defined by the Public Contracts Regulations 2015 (PCR 2015), SI 2015/102 as an agreement between one or more contracting authorities, and one or more economic operators, with the purpose being to establish the terms governing contracts to be awarded during a given period, in particular with regard to price and where appropriate the quantity envisaged (PCR 2015, SI 2015/102, reg 33(2)).
