Before driving into London you should check whether you'll need to pay the ULEZ charge using the TfL vehicle checker. You should also check if your destination falls within the expanded ULEZ using TfL's postcode and map search tool. This will also tell you if you have to pay the Congestion Charge.

In 2026, the most reliable way to determine if you owe the Ultra Low Emission Zone (ULEZ) charge in London is to use the official Transport for London (TfL) "Check Your Vehicle" tool. By entering your vehicle's registration number (VRN), the system instantly identifies if your car meets the Euro 4 (petrol) or Euro 6 (diesel) standards required to avoid the £12.50 daily fee. It is important to note that as of 2026, almost all fully electric vehicles remain exempt, but some older hybrids may no longer qualify for discounts. Additionally, you should check the TfL map to see if your destination falls within the expanded zone, which covers all London boroughs. If your vehicle is non-compliant and you drive within the zone, you must pay by midnight on the third day following the journey to avoid a Penalty Charge Notice (PCN), which has increased to £180 in 2026.
