Subsidy helps to cut costs
Regulator Ofgem has a statutory role in protecting vulnerable consumers.
It has a particular role to play in regions across the UK where there is a higher risk of fuel poverty, such as the Highlands.
Ofgem said the north of Scotland network operator receives a cross-subsidy through the Hydro Benefit Replacement Scheme, so customers face lower network charges than they otherwise would.
This subsidy is not met directly from the hydro operators but is recovered from suppliers across Britain through a charge added to all units of electricity.
The cross-subsidy is around £41 per year per household in north Scotland.
For non-gas households, the Fuel Poverty Network Extension Scheme offers funding towards the cost of connecting to the gas network.
Between 2016 and 2021 gas distribution companies will have to deliver 18% more of these connections across the country.
