Westminster operator coverage runs across the W1, SW1, WC1, WC2 (plus 1 adjacent prefixes) postcode areas. Urban dispatch positions trucks near the principal arterials so that recovery within the postcode area meets the published response target. Postcode adjacency, not administrative boundary, determines which depot the dispatcher routes to a given call.
W area: W postcode area covers central and west London from Marble Arch through Notting Hill, Shepherds Bush, Ealing and out to Hanwell. The A40 Westway elevated dual carriageway runs the spine from White City east to Paddington, and the A4 Cromwell Road and Talgarth Road run parallel to the south. The Hanger Lane gyratory where the A40, A406 North Circular and A4005 meet is a chronic congestion point and a frequent incident site. The whole area falls inside the August 2023 ULEZ expansion and the central Congestion Charge zone covers the eastern W1 and W2 postcodes.
SW area: SW postcode area covers southwest London from Chelsea and Battersea through Wandsworth, Tooting and out to Wimbledon and Putney. The A3 Kingston Road, A24 Tooting High Street and A205 South Circular form the principal arterials. The Wandsworth gyratory and the Chelsea Bridge Road approaches to Battersea Park constrain central recovery access. The whole area falls inside the August 2023 ULEZ expansion and the central Congestion Charge zone covers the northern SW1 postcode through Victoria and Pimlico; the Vauxhall Bridge and Lambeth Bridge crossings are the standard recovery staging points.
WC area: WC postcode area covers central London from Bloomsbury and Holborn through Covent Garden and the Strand. The A40 High Holborn and A4 Strand form the principal east-west arterials, with the Aldwych one-way system having been remodelled in 2022 to a part-pedestrianised layout that constrains recovery routing. The Central London Congestion Charge zone covers the entire WC area on weekdays, layered with the London ULEZ at all times. Recovery work is constrained by narrow Georgian street widths around Lincoln's Inn Fields and the British Museum perimeter, with most low-loaders required to stage from the Kingsway A4200.
