Households are to be penalised if they do not switch away from gas under net zero plans to be unveiled on Thursday.
Ministers are planning to overhaul subsidy rules so gas is relatively less attractive compared to electricity in an attempt to drive the uptake of green power and hasten the end of fossil fuels.
The proposals risk forcing household gas bills up by as much as £100 a year, while electricity costs will come down.
Speaking on Wednesday, Grant Shapps, secretary of state for energy security and net zero, said: “If we want people to switch to an electricity-based economy, it would be better if [levies] were shifted onto the gas side of things.
“It automatically makes the economics of an electric-driven economy better.”
