The Ultra Low Emission Zone (ULEZ) in London was expanded on 25th October 2021 to include all roads inside the North and South Circular. Diesel cars that don’t meet Euro 6 clean car standards and petrols that don’t comply with Euro 4 attract a daily levy of £12.50 for driving in the zone (on top of the £15 Congestion Charge).

Birmingham has a similar scheme and there are plans to introduce charges in other major cities around the UK, including Derby, Manchester and Newcastle. In other words, it's not just people who live or work in London that need to be aware of the rules – and how much your choice of car can affect the day-to-day cost of driving it.

So, for those of you who live in or regularly hop in and out of these areas and are thinking of buying a used SUV, we’ve compiled a list of our top 10 ULEZ-compliant favourites. They come from a variety of different SUV categories, but all are diesel-powered for maximum economy, and all can travel into and out of the current zones without paying the ULEZ charge.
