The handover marks the end of a 13-year licence for Smart DCC, a subsidiary of Capita, after years of spiralling costs and delays

Control over Great Britain’s 39m smart meters has passed to a non-profit startup after its former owner presided over more than a decade of spiralling costs and delays in the troubled network.

The company owned by crisis-hit outsourcing firm Capita has promised a “seamless transition” to its not-for-profit successor, which will take over running the data network connecting the smart meters from this week.
