New energy watchdog boss vows to get tough on rip-off tariffs

Jonathan Brearley says Ofgem needs to balance new net-zero carbon goals with protecting consumers

Jonathan Brearley might be the most important British climate pioneer you've never heard of. In the past 10 years, the former civil servant has quietly steered the UK to its first climate legislation, and then to the policy framework responsible for creating Britain's cleanest electricity system since the 1880s. As the new chief executive of Ofgem, Brearley plans to inject climate action into the core of the UK's energy regulation, too.

This may prove his toughest challenge yet.
