UK Ministers have been urged to “rethink” the pace of change to reach net zero by right-wing Conservative MPs.

The UK Government has vowed to protect consumers from “any rising costs” associated with green policies.

It came as right-wing Tories urged the Prime Minister to review the deadlines around environmental measures after voter concerns about the expansion of London’s ultra-low emission zone (Ulez) which has been blamed on helping the party hang on to Boris Johnson’s old Uxbridge and South Ruislip during last week’s by-election.

The Tories had claimed the result showed the party could pull off a shock general election victory and its chances are not completely over if it can focus on issues where there is a clear divide with Labour.

The UK Government has also been criticised by its statutory climate advisers, the Climate Change Committee for sending mixed signals over its ambitions to reach net zero after pursuing the expansion of drilling for fossil fuels in the North Sea.

Former business secretary Sir Jacob Rees-Mogg and Danny Kruger, the co-leader of the New Conservatives, a group of Tory MPs elected since the Brexit referendum, both called for green deadlines to be reconsidered on Sunday.

Rishi Sunak is said to be considering delaying or ditching climate change-tackling measures that could impose costs on consumers.

One of the options on the table is an exemption for smaller car manufacturers — dubbed an “Aston Martin exemption” — on the 2030 ban on new petrol and diesel cars in England, according to The Times.

The Scottish Government has also committed to a 2030 ban.

The newspaper said the UK Government is also considering a ban on new low-traffic neighbourhoods (LTNs), with ministers reportedly weighing-up preventing councils from using the national number plate database to stop the zones being enforced.

No 10 said it could not comment on either suggestion although Mr Sunak is likely to be asked about them during a visit to the West Midlands on Monday ahead of the Government unveiling house building reforms.

The Department for Energy Security said the push to net zero would “provide customers with cheaper bills in the long term” but recognised there were concerns about the costs involved with the 2050 target.

A UK Government spokeswoman said: “We know that the number one concern for families up and down the country today is the immediate cost of living challenge and that’s why halving inflation is one of the Prime Minister’s top priorities.

“We’re working hard to stick to the plan to ease pressure on families, and we will always look to protect consumers from any rising costs.”

Senior Tory Sir Jacob said the lesson from the Uxbridge result, where the Tory majority was slashed from 7,200 to under 500 votes, was that ministers needed to “stop burdening” the public with “extra” green charges and regulations.

He told GB News: “What works is getting rid of unpopular, expensive green policies, and that is a real opportunity for us.”

He proposed “getting rid” of the 2030 ban on new petrol and diesel cars — announced during Mr Johnson’s premiership — arguing it was formulated “a few years ago in different circumstances”.

Devizes MP Mr Kruger told BBC Radio 4’s Westminster Hour: “We shouldn’t abandon green policies but we have got to work in a way that is sensible.

“And I think the whole population, young and old, recognise that we need a transition that is affordable and particularly affordable for working families, people who are struggling to make ends meet.

“And the cost to net zero at the moment is forecast to fall most heavily on them.

“I think we do need to bring the whole country along with us and we do need a rethink about the pace and the mechanism of the change we all want to see.”

It comes as landlords called for more clarity on suggestions from Housing Secretary Michael Gove that a deadline to improve the energy efficiency of private rented homes could be relaxed.

The UK Government had proposed during a consultation that by April 2025 all new-build tenancies would need a rating of “C” or better, with the same grade applied to all private rented housing by April 2028.

The Scottish Government has said that from 2025, certain trigger points such as the sale of a home, will mean properties will need to meet EPC band C energy efficiency standards, while new fossil fuel boilers will be banned in new buildings from next April.

The Herald on Sunday revealed that Patrick Harvie will reform the EPC gradings before the policy is rolled out.

Mr Gove said on Sunday that landlords were being asked to do “too much too quickly”.

Ben Beadle, chief executive of the National Residential Landlords Association (NRLA), said a two-year delay since the original consultation over the measures meant ministers had been warned there was “never any hope of meeting the originally proposed deadlines”.

Labour overturned a massive 20,000 Tory majority in the Selby and Ainsty by-election but was left conducting a public inquest into why it had fallen short in Uxbridge.

Leader Sir Keir Starmer blamed Mr Khan’s proposals to expand Ulez to all London boroughs for its loss in west London.

Mr Khan, the Labour incumbent in City Hall, plans next month — subject to a legal challenge — to widen the £12.50 daily charge for vehicles which fail to meet emissions standards, taking it beyond the capital’s north and south circular roads.

Iti s understood Mr Khan plans to stick by the policy, which is designed to cut air pollution in the capital, but he is currently looking at whether there are further ways of mitigating the financial impact on Londoners without reducing its effectiveness.
