Taxation (Energy and Vehicles)

The Chancellor has committed to doing what she can to support families and businesses to be responsive in a changing world and responsible in the national interest. The measures before the House assist the Government in that objective.

The way that the current energy system works means that households and businesses pay more for their electricity when the gas price is high. The electricity generator levy already recoups some of the excess returns made by renewable generators when high gas prices push electricity prices over the current threshold of £82.61 per megawatt-hour. The Government have decided to increase the rate of the levy from 45% to 55% from 1 July. That will do two things: first, it will ensure that a large proportion of any exceptional revenues from high gas prices are passed back to the Government, providing a revenue stream so that money is available to support businesses and families with the impacts of the conflict in the middle east; and secondly, in the longer term it will support the new voluntary contracts for difference scheme, which was announced in April, by encouraging participation in the scheme.

In March, the Government announced a review of mileage rates for employees using their own vehicle for work and the self-employed who use the simplified expenses rates. In recognition of the pressures facing drivers as a result of the effects of the Iran war, the Chancellor announced in May the first uprating of mileage rates in 15 years, backdated to April, to provide immediate support to both groups. Mileage rates will increase for 2026-27 from 45p to 55p for the first 10,000 miles, and then 25p thereafter, with effect from 6 April. That represents the largest ever increase to these mileage rates, benefiting around 2 million employees and 1 million self-employed individuals, and saving over £120 a year for a worker doing 6,000 business miles.

It was a privilege recently to meet care workers and the Unison general secretary to hear directly about the difference that this uprating will make to those on the frontline. The general secretary said to me and the Chancellor that this measure is good news for people providing essential public services. It was an honour to meet those who work day in, day out looking after people across the country. I am glad that this measure will have a positive impact on those who do such vital work. Looking ahead, beyond 2026-27, the Government have already committed to a review of those rates and will set out further steps at the Budget.

The third measure recognises the key role that the road haulage sector plays in transporting goods across the UK and its disproportionate exposure to fuel costs. The Government are introducing a 12-month holiday from vehicle excise duty for the majority of heavy goods vehicles, which will save a typical HGV £600 on top of the savings from fuel duty. Fuel costs make up a substantial proportion of HGV operating costs, and this action will help to prevent cost pressures from the Iran conflict spreading across the economy.

The announcements on mileage rates and HGV VED were part of a wider package of measures announced in May, including on fuel duty. In total, the decisions taken since the 2024 general election to freeze fuel duty will save motorists 11p per litre, or £120 for the average car, £250 for the average van and over £2,000 for the average HGV, compared with the plans we inherited from the previous Government.

This Government are taking action to support the economy at a time of global economic uncertainty following the Iran conflict. Our approach of targeting support at those groups who are hardest hit by the conflict will ensure that the measures we take are effective, while protecting the economy from the effects of reckless borrowing that took place under the previous Government.
