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, LowCVP 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 award support to winning bids. 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.
Contact daniel.hayes@lowcvp.org.uk to discuss potential bus models that may qualify for ULEB accreditation.

The list below includes approved certificates and the manufactures looking to achieve ULEB Accreditation.
Infrastrucutre & Fuel Providers
The provision of infrastructure is crucial to the operation of a number of Low and Ultra-Low Emission Buses. Often infrastructure can be the greatest challenge when deploying new technologies, can have the longest lead time and involve a wide range of stakeholders beyond the manufactuer and operator. The integration of additional equipment and the knowledge and training required to understand the safe operation requires attention to ensure an effective operation.
The following LowCVP members provide infrastrucuture solutions that support the operation of Low and Ultra-Low Emisison Buses:
Electric Infrastructure
Different manufacturers offer different charging solutions for battery electric and plug-in hybrid buses. Each solution will have its advantages depending on the type of operation, topographies and even local culture. The following LowCVP members provide a variety of solutions with case studies across the UK

Biomethane
Biomethane can be supplied to a depot through two methods; via the mains gas grid or in compressed form delivered by truck or tanker. In order to minimise costs, a permananent grid connection is favoured in the long term.
Ther are two refuelling infrastructure models to suppport the operation of biomethane buses. These are often dependent on the location of the depot in regards to a local gas main and the size of the fleet of buses being refuelled.
Procure and Opeartor or Wet Leasing?
Operators have a choice when choosing biomethane as a fuel as to how they wish to pay for the infrastrucuture and supply of fuel. The operator can buy the refuelling equipment outright and pay for a grid connection, along with the metered gas and green gas certificates.
