What Clean air zone (CAZ) means for you
Clean air zones charge drivers whose vehicles don't meet the zone's emissions standard. London's ULEZ charges £12.50 a day for petrol cars that don't meet Euro 4 (most from 2006) or diesel cars that don't meet Euro 6 (most from September 2015). It runs 24 hours a day, every day except Christmas Day. Electric cars always comply.
Before buying, check the car meets the standard for the area you'll drive in. Our free check shows ULEZ status. In Glasgow, Edinburgh, Aberdeen and Dundee, low emission zones issue a £60 penalty, halved if paid in 14 days.
