The approach to modifications/variations of contracts (and when such amounts to a new award of a contract) changed when Public Contracts Regulations 2015 (PCR 2015), SI 2015/102 came in to force, as the rules in relation to this area were codified in PCR 2015, SI 2015/102, reg 72. A voluntary transparency notice (also known as a voluntary ex-ante transparency notice or VEAT notice) is used in limited circumstances arising under PCR 2015, SI 2015/102 in order to resist challenge on grounds of ineffectiveness under PCR 2015, SI 2015/102, reg 99. It is important to note that a VEAT notice will only be valid if the contracting authority believes the decision being made does not fall foul of PCR 2015, SI 2015/102,
