Scottish Ultra-Low Emission Bus Scheme

SULEBS is currently closed to bids

This Scottish Ultra-Low Emission Bus Scheme (SULEBS) is an evolution of the Scottish Green Bus Fund held each year between 2011 and 2018. SULEBS supports the purchase of new buses, and assists with 50% of the cost differential between a standard diesel bus and the equivalent ultra-low emission bus. This can rise to a maximum 75% support of the differential for buses depending on their zero emission running capability. Support is also available for the infrastructure for this technology of up to a maximum 75% of the capital cost. 

SULEBS is part of the Scottish Government’s approach to meeting furthering our ambitions for a net-zero economy and improving air quality through a greener fleet.

A round of SULEBS ran between 19 August and 6 September 2020, and has resulted in five successful bids, totalling £7.4 million for the introduction of 41 ultra-low emission buses, and for infrastructure to support the running of ultra-low emission buses across Scotland.

The successful bidders are:

  • First Glasgow (No1)
  • Xplore Dundee
  • Orkney Islands Council
  • McGill’s Buses
