Norfolk Green has been shortlisted along with just three other bus services in East Anglia for the prestigious Bus Awards.
Previous winners, Norfolk Green and Ensign Bus, have been nominated for the Top Independent Operator award.
UK Bus Awards chairman John Owen said: “Despite the difficult economic times, this year’s entries demonstrated that creativity within the industry is still alive and well.
“The bar is constantly being raised, meaning that the innovation of a few years ago is now the everyday standard in many places.
“Our judges have been genuinely impressed with the commitment to higher standards in all areas of the business.”
More than 100 people, projects and services across the UK have been selected by judges from over 250 nominations and will go on to the final stages, including mystery traveller checks.
The 2013 UK Bus Awards will be presented on November 19 in London.
