Low Emission Zone Retrofit Fund Self-referral portal

Step 1 - Low Emission Zone Retrofit Fund

To address local air quality and improve public health, Low Emission Zones (LEZs) have been introduced to the cities of Glasgow, Edinburgh, Dundee, and Aberdeen. LEZs restrict the vehicles entering the zones based on emission standards; older more polluting vehicles will be unable to enter without penalty following an initial grace period.

To support the transition to meet LEZ requirements, Transport Scotland is offering eligible businesses 70% funding per vehicle (to a cap value depending on vehicle and solution type) to retrofit their vehicle to meet zone standards through the LEZ Retrofit Fund administered by Energy Saving Trust.

If you wish to retrofit multiple vehicles (up to the maximum three vehicles) please complete a separate form for each vehicle.

IMPORTANT: This fund is currently closed following full fund allocation, by completing this form you are confirming you wish to be contacted if the fund relaunches in future.
