The CCC sees signs of progress, including a near doubling of the number of electric cars on UK roads in the past two years.

While new electric cars remain more expensive to buy than their petrol equivalents, the CCC expects them to cost the same in a couple of years.

"We see these transitions happen surprisingly fast once they get going, usually starting slowly and accelerating rapidly, where falling prices and rising demand reinforce each other," said Dr Emily Nurse, the CCC's head of net zero.

That's because the cost of electricity is so high, something the CCC has repeatedly said needs tackling.

The single largest reason for the rise in household electricity prices in recent years is the increase in wholesale costs, driven by international gas prices, the CCC says.
