It is hoped that moving some of those charges on to bill-payers could encourage more charging points to be built in areas such as workplaces and car parks.
Ofgem believes the costs will be relatively small, about £380m over 17 years, which works out at about £22m per year.
However, the plans are an early indication of how the efforts to overhaul the nation’s transport to cut carbon emissions could be paid for.
The arrangements would also apply to the costs of new connections to the grid for other purposes, such as heat pumps or factories that need more power. Both will be in greater demand as the country tries to cut down on fossil fuels to meet its legally binding target of net zero carbon emissions. In consultation papers, Ofgem says current arrangements risk slowing down that effort.
