London drivers are set to face an extra daily fee of £12.50 as mayor Sadiq Khan announces plans to expand the ultra-low emission zone (ULEZ). 

The zone will officially be extended to the whole of London from August 29 in a bid to boost air quality. 

The scheme will operate every day at all times, apart from Christmas day is currently limited to the area within the North and South Circular roads but will soon cover all of Greater London. 

Transport for London (TfL) estimates that on an average day about 160,000 cars and 42,000 vans that use London’s roads would be liable for the £12.50 Ulez fee.

However, transport officials have said they hope the ULEZ scheme will encourage tens of thousands of those drivers to switch to vehicles that comply with the minimum emissions standards or use other modes of getting around such as walking, cycling or public transport.

Whether or not a vehicle is liable for the charge depends on how much nitrogen dioxide it emits.

Diesel cars and vans can avoid the charge by being registered from 2016 whilst most petrol models registered from 2006 are exempt.

Drivers can check the status of their vehicle by entering its registration number on TfL’s website.

Speaking of the decision to expand the ULEZ, Mayor Khan said air pollution is making Londoners “sick from cradle to the grave”, with illnesses such as cancer, lung disease, dementia and asthma.

Sharing: “Expanding the Ulez London-wide has not been an easy decision.

“The easy thing for me would have been to kick the can down the road.

“But in the end, public health comes before political expediency.”

The mayor did also share that the rising cost of living was a “key consideration” in his decision on whether to implement the proposal, which was featured in a public consultation between May and July.

Leading him to introduce measures such as a £110 million scrappage scheme to support Londoners on lower incomes, disabled people, small businesses and charities to scrap or retrofit their non-compliant vehicles.

TfL has also confirmed that there will be a major expansion of bus services in outer London.
