Uno was set up as an 'arm's length' company by the University of Hertfordshire in 1992.
It has its own Board of Directors and is expected to run on a fully commercial basis.

In 2005 it was re-branded Uno and the buses were repainted pink and purple, a departure from the previous grey and white livery.
According to the University's student newspaper Universe, the reason for the re-branding "is to have a name that reflects the wider market the buses serve in the community, basically not just for the inhabitants of the University of Hertfordshire".

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.
 The partnership uses powers under the most recent Transport Act as a Quality Network Partnership but is known publicly as 'Network St Albans'.
Uno is currently the second largest bus operator in Hertfordshire.

On 20 April 2009, Uno recast many of its services to integrate a number of the former Centrebus routes.
Further changes took place on 28 September 2009, following the opening of the new University Of Hertfordshire Forum.
These changes included improvements to late evening services and the extension of operating hours until as late as 3:30am for a select few routes.
The main timetable change each year takes place in September to coincide with the start of the school, college and university academic year.

In September 2012, Uno commenced operating in Northampton, initially taking over routes 18 and 19, both of which serve The University of Northampton.
A third service, route 21, began operating in 2013, covering some of Northampton's eastern district and serving Northampton College.

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

On 25 July 2015, Uno became a contracted Transport for London operator when it commenced operating route 383.

In November 2016, Uno's Northampton operations were shortlisted for the Top Independent Operator award in the national UK Bus Awards; they finished as a finalist.

In November 2018, Uno were shortlisted for several awards in the UK Bus Awards and won two - Marketing Initiative of the Year for the 'Comet' route (614/644) and Leadership & Inspiration for the MD, Jim Thorpe.
