The UK is divided into 43 zones for air quality assessment. There are 28 agglomeration zones (large urban areas) and 15 non-agglomeration zones. The geographical boundaries of air quality zones and agglomerations in England are set out in the Air Pollution in the UK Report (see attached) and are also made available through the compliance map on the UK-Air website.
