Clean air zones and emissions charges are gradually being introduced to improve air quality and reduce emissions. This includes London’s Ultra Low Emission Zone and congestion charge, but also other cities across the UK.

Make sure you don’t get caught out with extra charges if you drive for your small business. From key dates for your diary to which vehicles the charges apply to, read up on the rules so you aren’t hit with unexpected penalties.

This article covers everything you need to know, including:

What is ULEZ?

The ULEZ clean air charges were introduced in London in 2019 to manage air pollution that causes environmental and health risks. It applies all year round, 24 hours a day, seven days a week (apart from Christmas day).

ULEZ expansion – what’s changing?

From 29 August 2023, a further ULEZ expansion means the London ULEZ will include everything within the Greater London Authority boundary.

Initially the zone just covered central London, but it expanded in October 2021 up to (but not including) the North Circular Road (A406) and South Circular Road (A205).

The August 2023 expansion means all London boroughs will be covered by ULEZ, making it 18 times larger than when it was first introduced in 2019.

The planned expansion has been under the spotlight, with some of London's councils voicing concerns about the scheme. Many are worried the added costs of driving and owning a vehicle in London will be challenging for small businesses owners already grappling with the cost of doing business crisis.

The levels of polution have reduced since the scheme was introduced, according to a study from the Greater London Authority and TFL. It found that emissions of toxic nitrogen oxides are 23 per cent lower across London, compared with the estimated level if the scheme didn't exist.

ULEZ check – do you need to pay the charge for your business vehicle?

You can use TFL’s vehicle check tool to see if your vehicle is exempt from the charge. You just need your car registration number to find out.

Typically, vehicles that don’t meet the emissions standards and have to pay the ULEZ charge are:

  • petrol cars and vans that don’t meet Euro 4 standards (typically vehicles registered before 2006)
  • diesel cars and vans that don’t meet Euro 6 standards (typically vehicles registered before 2015)
  • motorbikes that don’t meet Euro 3 standards (sold before July 2007)

Electric vehicles are exempt from the charge. Check other exemptions and grace periods with TFL.

How much is the ULEZ charge?

If you’re driving in the area and your vehicle doesn’t meet specific emissions and safety standards (typically older vehicles) then you have to pay £12.50 a day. You don't have to pay if your car is parked in the zone on days you're not driving.

There’s a penalty charge of £180 if you fail to pay by midnight on the third day following the journey, although this is reduced to £90 if you pay within 14 days.

You can use TFL’s congestion charge tool to check if the charges apply to your business vehicle.

How to pay

You can pay the charge in a number of ways:

  • set up Auto Pay – this gives you the option to register up to five vehicles if your business regularly uses multiple vehicles, and you’ll be charged automatically so you won't have to worry about forgetting to pay the charges
  • TFL app – using the app you can set up to auto-pay, make payments, and view your balance
  • by phone – call 0343 222 2222 to pay the charge over the phone

Claim tax relief on ULEZ charges

Small businesses driving in the UK capital will be able to claim tax relief on the daily ULEZ charge.

HMRC confirmed on 29 August 2023 that the charge will be classed as an allowable business expense. This means the self-employed can deduct the amount from their taxable profits and reduce the amount of tax they need to pay.

The relief only applies to journeys made for business purposes – and doesn't include commuting.

What is London's scrappage scheme?

Londoners with high-polluting vehicles will be able to access money to replace them through the ULEZ scrappage scheme.

There are grants of up to £11,500 available for businesses, depending on the type of vehicle they drive.

Read our guide to the scrappage scheme for more information on how it works and how to apply for a grant.

Don’t forget about the London congestion charge

You’ll need to pay a congestion charge if you drive at certain times in central London.

Congestion charge times apply between 7am and 6pm during the week (Monday to Friday) and between 12pm and 6pm on weekends and bank holidays. Charges don’t apply between Christmas Day and the New Year’s Day bank holiday.

Check the congestion charge map on TFL’s website to see if charges apply. You’ll know if you’re in a congestion charge zone as there are signs showing a white ‘C’ in a red circle.

It costs £15 a day and can be paid for the same way as the ULEZ charge. TFL has more information on paying to drive in London.

Electric vehicles are exempt

If you drive an electric car or van, then you’ll be exempt from both the Ultra Low Emission Zone charge and the congestion charge – this could save you £27.50 every day.

Read our guide to choosing an electric vehicle and how to decide if you need one for your business.

Clean air zone cities across the UK

There aren’t any other ULEZ cities beyond London, but there are other cities with low emission zones in the UK.

Below is an overview of which cities have a clean air zone and when the charges apply:

National exemptions apply if you have a eco-friendly vehicle that meets the low emissions standards. However, many of these cities also offer discounts or grants for small businesses located within the clean air zones.

It's also worth noting that you can claim these charges as a tax-deductible expense, provided the journey you made was solely for business purposes.
