This study comprises meter reading and consumer survey data from the UK's first residential sector, dynamic time-of-use electricity pricing trial, which took place as part of the Low Carbon London (LCL) project. The trial involved 5,567 households in the London area, of which 1,122 received an experimental dynamic time-of-use (dToU) tariff, which was in effect for the duration of 2013.

The Low Carbon London project was a £28m research programme that ran from the beginning of 2011 to the end of 2014 and was funded by energy consumers via Ofgem's Low Carbon Network Fund. The programme was designed to investigate the impact of a wide range of low carbon technologies on London's electricity distribution network. It was in this context that the UK's first residential sector, dynamic electricity-pricing trial took place. The trial was carried out by a partnership of organisations: UK Power Networks, the London DNO and the lead programme partner; Imperial College London, responsible for trial design and results analysis; EDF Energy, retail energy supplier and implementer of the dToU tariff; Siemens, responsible for database and communications implementation; and Logica (now CGI), the smart meter head-end.

The learning objectives of the trial were twofold: to understand the potential value of dynamic pricing to the electricity system, and to understand its social impact on residential consumers.
