In November 2015, for the first time, uniform provisions on net neutrality in the form of a regulation were adopted (so called Telecom Single Market-Regulation, short "TSM", see downloads). The regulation has been applicable since 30 April 2016.
With Art. 50 of the BEREC regulation (Regulation (EU) 2018/1971) the regulation was renamed to "Regulation (EU) 2015/2120 of the European Parliament and of the council of 25 November 2015 laying down measures concerning open internet access and retail charges for regulated intra-EU communications and amending Directive 2002/22/EC and Regulation (EU) No 531/2012".
In the regulation, BEREC is obliged to issue guidelines in order to contribute to a consistent application of the regulation. On 30 August 2016, BEREC finalised the guidelines. According to the BEREC work programe 2019 these guidelines are currently updated. On 30 April 2019 the European Commission published a report on the implementation of the net neutrality regulation.
