The United Kingdom’s Competition and Markets Authority (CMA) recently concluded its investigation into the effectiveness of competition in Great Britain’s gas and electricity markets. The purpose of the investigation was to identify issues creating adverse effects on competition and, where they exist, to address them with remedies aimed at promoting competition.


Brattle Principals Dr Pinar Bagci and Dr Serena Hesmondhalgh advised one of the six large energy firms at the focus of the investigation. In a new Brattle article, Drs Bagci and Hesmondhalgh examine the key findings of the energy market investigation and comment on the possible effects of the CMA’s decision to implement a transitional price cap for prepayment meter (PPM) customers, impacting nearly four million households.
