The first signs of how the U.K. electricity market will look from next year have emerged, with different daily prices potentially hiking costs for homes and industrial users.

For almost a decade, the U.K. has operated with two foreign-owned exchanges jointly setting a national price used to decide everything from flows to the continent to industrial rates. This co-operation will end next year when the nation isn’t bound by the European Union’s internal energy market rules. Each exchange will then produce its own daily reference price.
