Government risks £30bn financial black hole without net zero roadmap

Britain’s biggest housebuilders privately lobbied for the government to ditch rules requiring electric car chargers to be installed in every new home in England, documents have revealed.

The Government risks a £30bn-plus yearly black hole in its tax policy, if it fails to find a meaningful alternative to fuel duty during the transition to electric vehicles (EVs), warned environmental think tank Green Alliance.

It has called for Downing Street to come up with plans to fill the revenue gap as EVs move into the mainstream market, such as road user charging and carbon levies.

Green Alliance said: “A tax roadmap for net zero should prepare the ground for Government action to address these fiscal realities. This is most urgent in the case of fuel duty, which currently raises £30bn a year and will rapidly diminish as the nation’s car fleet electrifies.

“Tackling this early with plans to fill the gap left by fuel taxes, for instance through road user charging, will make implementation less politically challenging.”

In its latest report on taxes and green energy, Green Alliance warned the UK’s tax system remains geared towards a high carbon economy.

It cited data from the Office for Budget Responsibility, which showed it risked the equivalent sum of a 1.6 per cent GDP hit to its economy in 2025/26 over the next three decades from decarbonisation.

This does not include losses of revenue caused by the contraction of North Sea oil and gas.

Currently, fuel duty raises £33.6bn per year from fuel duty, but this is expected to decline as EV sales rise.

The Government is targeting the end of sales for all new petrol and diesel cars by the end of the decade, making the question of replacing fuel duty even more urgent.
