London’s Ultra Low Emission Zone expanded on 29th August 2023 to cover more areas of the city. Based on your vehicle's emission standard, you have to pay a daily charge of £12.50 to drive in these zones. Driving in these zones without paying the ULEZ charge will result in much bigger fines. This is applicable for vehicles that are registered within the UK and outside the UK. Don't worry if you don't know the emission standards of your vehicle. Our free ULEZ checker tool helps you to find whether you have to pay the ULEZ fee just by submitting your vehicle's Plate number. We also have an interactive ULEZ zone map. You can see whether a location belongs to this zone by pinching and zooming. Alternatively, you can submit the postal code to check whether that area comes under the Ultra Low Emission Zone.
