A hard Brexit could add up to £ 270 ##m ( $ 341 m ) to the annual electricity bill of UK consumers if the UK leaves the internal energy market ( plc ) , according to the UK Energy Research Centre ( UKERC ) . The introduction of the IEM enabled trades to take place at actual retail prices , rather than at anticipated prices , which often led to errors and inefficient trading . It would cost the British and French markets around £ 500 m more by 2030 if their energy markets were uncoupled in a hard currency , compared to a soft Brexit where the UK would remain part of the IEM , UKERC claims .
