It provides student transport to the university from local areas as well as improving east–west travel across Hertfordshire and has opened up new links from North London.

Other developments on this site, including business premises for companies such as Veolia, DHL and EE have also provided passengers.

As a result, in March 2005, Universitybus was rebranded as Uno, with the operator's fleet adopting a pink and purple livery designed by Best Impressions.

[2] Shortly after purchasing the St Albans operations of Centrebus in 2008, Uno helped to found a voluntary partnership of local authorities, the university and the bus and rail operators serving the city with the aim of co-ordinating and improving public transport across St Albans.

[3] In September 2013, Uno began operating a small network of routes between Milton Keynes, Bedford and Flitwick for Cranfield University.

Uno operates from a garage purpose built in 2003 at Gypsy Moth Avenue, Hatfield Business Park.

A similar arrangement also operates at Cranfield University following initiation of services between Milton Keynes and Bedford in September 2013.

In September 2017 Uno launched a fleet of six brand-new, high specification buses on the 614/644 routes between Hatfield and North London, rebranded by the company as 'The Comet'.

The buses feature WiFi, USB charging sockets, on-board stop announcements and an innovative sofa at the front.

[17] In February 2019, further investment by the company saw a fleet of 8 buses launched under the 'Tigermoth' brand for the 653 route - each bus named after the first eight female pilots from the Air Transport Auxiliary (ATA) - Joan Hughes, Margaret Cunnison, Mona Friedlander, Rosemary Rees, Marion Wilberforce, Margaret Fairweather, Gabrielle Patterson, and Winifred Crossley Fair - who were based at Hatfield in the Second World War.
