Ultra Low Emission Bus Certificates

This page displays the Ultra-Low Emission Bus certificates for models approved to receive funding from the Department for Transport's £48m Ultra-Low Emission Bus Scheme. 

ULEB accreditation is required to ensure public money supports proven technologies that will perform in-service. Certificates enable local authorities and bus operators to receive government funding under the ULEB scheme. To achieve accreditation and be awarded a certificate, manufacturers must achieve a 30% well-to-wheel greenhouse gas saving compared to a conventional Euro VI diesel over the UK Bus Cycle. Find out more about accreditation here.

Once a manufacturer has proven that a model achieves the ULEB standard, Zemo Partnership and DfT review the certificate and publish it below along with highlights of the vehicle's performance.

Certificates are not required in order to apply for the ULEB scheme, but a manufacturer must achieve accreditation for DfT to release funds to winning bidders. A manufacturer should be able to provide an estimate as to the expected performance of a vehicle of over the UK Bus Cycle. See the Low Emission Bus Certificates for details of performance of previous technologies.
