He also scrapped plans that would have made rental properties more energy efficient.
But with changes still years into the future – and the cost of living crisis rumbling on – will pushing deadlines back make a difference to people’s finances now? Here, Sky News takes a look.
When he was prime minister in 2020, Boris Johnson committed to banning the sale of any new petrol and diesel cars in the UK from 2030. This is now being pushed back until 2035.
Plans to fine manufacturers for each vehicle that doesn’t comply are also being watered down.
Figures show that although petrol and diesel are still the overwhelming majority – the numbers of plug-in and battery electric vehicles on UK roads have increased – by 45% and 58% respectively.

And in 2023 more electric vehicles were registered than diesel ones for the first time.
This shows a “general trend” away internal combustion engines (ICE) – and towards more sustainable modes of transport already, says Oliver Montague, chief-executive and co-founder of the e-bike engineer company Swytch.
So a change in the timing of the ban is unlikely to have much of an impact.
“Those who have to transition [to EVs] will still have to do so – they just have more time to do it,” he tells Sky News.
“The real shift will be for people who can choose how they want to get around – who aren’t already hooked to one particular mode of transport” – such as a diesel car that needs trading in.
And with the average car journey being only around eight miles – he believes many will opt for e-bikes or cycling, instead of an electric vehicle, meaning the ICE ban will have even less of an impact.
The RAC also notes the ban only covers new petrol and diesel cars, which means “a lot of people won’t be affected as the majority tend to buy used vehicles”.
Mike Childs, head of science, research and policy at Friends of the Earth, adds that people will still be able to buy non-UK manufactured EVs.
“From a consumer perspective it won’t have a great impact because they can just buy Chinese or German EVs,” he tells Sky News.
“But for British manufacturing it’s a huge backwards step and a massive shot in the foot for jobs.”
No gas boilers in new homes
Plans to stop new build properties being fitted with gas boilers beyond 2025 are being pushed back 10 years.
This doesn’t affect people who already have gas boilers, who won’t need to replace them with alternatives such as heat pumps. As a result, this change is more likely to affect developers than consumers.

Jess Ralston, energy analyst at Energy and Climate Intelligence Unit, says that with a greater upfront cost for heat pumps, we won’t know until the changes come in how much of that will be passed on to buyers.
But she adds: “As time goes on heat pumps are going to be cheaper to buy and run anyway.”
Plans for all new heating systems to be low carbon by 2035, including £450m in household grants, has also been scrapped.
This means more people will have gas boilers for longer, which with prices “two to three times’ pre-crisis levels” will mean people paying more in energy bills, Ms Ralston adds.
But on Wednesday Mr Sunak did announce a 50% increase in the boiler upgrade scheme, which offers people £7,500 to help with the costs of switching from a boiler to a heat pump.

More energy efficient landlords
In 2020, Boris Johnson also pledged that from 2028 all rental properties would have to have an energy efficient rating of C or higher (A being the best and G the worst). But Mr Sunak is scrapping this due to “cost of living challenges”.
Ms Ralston says she “cannot get a single shred of logic” from the decision.
“This would reduce people’s energy bills in the cost of living crisis and increase energy security – things that the government say they want to be doing. It makes no sense whatsoever.”
Mr Childs says it will disproportionately affect people on lower incomes who are more likely to rent their homes.
“This is a massive kick in the teeth to people who live in cold, damp rented homes that are expensive to heat.
“It’s also a massive handout to landlords who can’t be bothered to insulate their properties properly,” he says.

He adds that despite some drop in prices this year, the cost of oil and gas is increasing again – and will remain volatile for as long as Russia is at war with Ukraine.
“There are more renters than there are landlords, so it makes no sense on votes. It just begs the question of whether the government are being lobbied by wealthy landlords,” Ms Ralston says.
Hydrogen levy
The government was proposing to introduce a levy of around £100 on household energy bills in 2025 – to help pay for low-carbon hydrogen production.
But after many claimed the hydrogen was being used primarily in industry – not people’s homes – ministers have scrapped it.
This is being welcomed by environmental and consumer groups.
Ms Ralston says that heat pumps are far more efficient than hydrogen for heating homes – so the government was right to recognise this wasn’t something the public should pay for.
Mr Childs adds that hydrogen still relies on natural gas – which both homes and transport have been moving away from, so Friends of the Earth has been “against it from the outset”.
Wes Streeting has defended plans to make over 70s take compulsory eye tests every three years – which could see them banned from driving if they fail, it is understood.
Ministers are considering “tougher” measures to tackle road deaths and injuries in England and Wales, which they believe have “remained stubbornly high under successive Conservative governments”.
Under the new proposals, first reported by The Times, the drink-drive limit would be lowered to match the current rules in Scotland.
Currently, the drink-drive limit is 35 micrograms of alcohol per 100 millilitres of breath in England and Wales, or 80 milligrams of alcohol per 100 millilitres of blood.
But this is expected to be lowered to 22 micrograms of alcohol per 100 millilitres of breath or 50 milligrams of alcohol per 100 millilitres of blood, to match the stricter levels already enforced in Scotland.
Those caught not wearing a seatbelt could also receive penalty points for the first time, while drivers found on the road without insurance could also face more severe consequences.
As well as this, plans are currently being drawn up to make those aged 70 or over take a compulsory eye test every three years when they renew their driving licence.
Those who fail this would lose their right to drive under the proposals. It’s understood that tests for other conditions, such as dementia, are also being considered.
Speaking on Monday, Mr Streeting said the transport secretary is consulting and “considering a whole range of proposals”, which will be unveiled in the “not too distant future”.
It is understood that Heidi Alexander will unveil the measures in a new road safety strategy in the autumn.

The health secretary also defended the plans around elderly drivers.
He told broadcasters: “It cannot be right that we’ve ended up in a situation where the NHS is hit with a £2 billion a year bill because we are not taking road safety seriously enough – particularly as we get older and the quality of our eye health deteriorates, that we’re not keeping a regular check.”
A Labour source said: “At the end of the last Labour government, the number of people killed and seriously injured on our roads was at a record low, but numbers have remained stubbornly high under successive Conservative governments.
“In no other circumstance would we accept 1,600 people dying, with thousands more seriously injured, costing the NHS more than £2bn per year.
“This Labour government will deliver the first Road Safety Strategy in a decade, imposing tougher penalties on those breaking the law, protecting road users and restoring order to our roads.”
It comes after 1,633 people died in road traffic accidents in 2024, with nearly 28,000 victims seriously injured.
Image: The UK Health Security Agency (UKHSA) has issued alerts across England
The UKHSA, a government agency for England, warned “significant impacts are likely” across health and social care services due to the high temperatures.
Parts of the country are facing a fourth heatwave of the summer, where highs pass a threshold on three consecutive days.
A yellow alert, also between 9am on Tuesday until 6pm on Wednesday, covers the North East, North West, Yorkshire, The Humber, and the South West.
Dr Paul Coleman, consultant in public health at UKHSA, said temperatures are forecast to rise above 30C (86F) across some areas which “can result in serious health outcomes” particularly for the elderly or those with serious health conditions.
“If you have friends, family or neighbours who are vulnerable, it is important to ensure they are aware of the forecasts and are following the necessary advice.
“Check in on them if you can to make sure they know that hot weather is on the way and how to keep themselves safe,” Dr Coleman said.

Sky News meteorologist Christopher England said the high pressure that brought the warmth of the last few days via the “heat dome” effect is moving east, as low pressure moves in towards the west.
“On Tuesday, southern Britain can expect temperatures widely into the low 30s… perhaps exceeding 35C (95F) in places,” he said.

Drought in England explained
On 1 July, the UK recorded its hottest day of the year so far with a temperature of 34.7C (94.4F) recorded at St James’s Park in central London.
The Met Office’s criteria for a heatwave are met when temperatures are above a certain level for three consecutive days. This threshold varies from 25C to 28C (77F to 82F) depending on the location.

Mr England added: “There’s around a 10% chance Wales may exceed its August peak temperature of 35.2C (95.3F) recorded at Hawarden on 2 August 1990.
“Expect some tropical nights too, with temperatures holding above 20C (68F).”
The UKHSA has issued advice for keeping cool: • close windows and curtains in rooms that face the sun • seek shade and cover up outside • use sunscreen, wear a hat and sunglasses • keep out of the sun at the hottest times, between 11am and 3pm • restrict physical activity to the cooler mornings or evenings • know how to respond to heat exhaustion and heatstroke
Around 30 residents have been evacuated from their homes in north London after a water main burst, leaving roads under 44cm (17in) of water.
Seventy firefighters were dispatched by London Fire Brigade to the area around Canonbury Street in Islington just after 10pm on Sunday.
People have been urged to avoid the area including Essex Road, Elmore Street, Halliford Street and Ecclesbourne Road – and warned against driving through floodwater.

Fire crews used flood barriers and sandbags to divert floodwater away from homes as they warned disruption was likely to continue into Monday afternoon.
Islington council also warned at 9am on Monday that Canonbury Street was closed from Essex Road up to Arran Walk.
A Thames Water spokesperson said: “We have now managed to stop the flow of water and ensure that the site is safe. We have also been able to move parked cars which were over another critical water main.
“We have a specialist team on site for those impacted by the incident, at Cedar Place on Essex Road, and are supporting customers who have been affected.
“To keep the public and our team safe, we’ve arranged equipment to help manage the traffic while we work in the road. We are sorry for the impact this may have on traffic in the area.”
