The Mayor of London, Sadiq Khan, has warned transport operators that, from 1 March, tighter standards will apply in the London-wide Low Emission Zone (LEZ) with regard to heavy vehicles including heavy goods vehicles (HGVs), buses and coaches.

They must now meet Euro VI (NOx and PM) emissions standards or pay a daily charge of up to £300.

These new standards apply to heavy vehicles across most of Greater London and match the emission standards of the central London Ultra Low Emission Zone (ULEZ). The vehicles affected are lorries, heavy vans or specialist heavy vehicles over 3.5 tonnes gross vehicle weight and buses/minibuses or coaches over five tonnes. 

The LEZ covers most of Greater London and operates 24 hours a day, every day of the year.   

Earlier this year Transport for London (TfL) announced that its entire 9000-strong core bus fleet complies with the LEZ standards and now meets or exceeds the cleanest Euro VI emissions standards.

For the majority of vehicles, the strengthening of the LEZ standards means that they are no longer separately subject to LEZ and ULEZ standards.

The exception is for vans between 1.2 and 3.5 tonnes and minibuses under five tonnes where the LEZ and ULEZ standards are different. These vehicles will need to comply with both schemes if they drive into the ULEZ area, or pay both sets of charges.

Anyone driving one of the above vehicles into the LEZ which does not meet Euro VI (NOx and PM), will need to pay the daily LEZ charge. If the vehicle meets Euro IV or V (PM), they will need to pay a daily charge of £100; if it does not meet Euro IV (PM), they will need to pay a daily charge of £300.
