The Scania OmniCity single-decker has a rounded roof dome with a single-curvature windscreen and a separate destination display.

The Go-Ahead Group were the most popular customer of the rigid single-decker OmniCity, purchasing a total of 132 of the type, seventy of these going to Metrobus of Crawley for both its London and south-east England operations.

[19] The first production order was made by Lothian Buses of Edinburgh, who took delivery of five N230UD OmniCitys during 2006 for the 'Airlink' express network.

In the United Kingdom, a demonstrator toured London between 2004 and 2005, but failed to win any orders in place of the Mercedes-Benz Citaro.
