The Low Emission Zone (LEZ) Retrofit Fund can help you improve your vehicles and avoid LEZ penalties. If you operate non-compliant vehicles that have retrofit solutions available in a planned LEZ, you could receive funding to cover up to 50% of the costs to make these changes to your vehicle.

By retrofitting vehicles with solutions approved by the Clean Vehicle Retrofit Accreditation Scheme (CVRAS), you can reduce your vehicle emissions and help improve local air quality. By becoming LEZ compliant, you can also avoid penalties.

This fund is aimed at Scottish microbusinesses and sole traders that operate within 20 kilometres of the Glasgow, Edinburgh, Aberdeen or Dundee low emission zones (LEZs).

To be eligible for the Low Emission Zone Retrofit Fund, your business must:

• be an active micro business or a sole trader, which means it:
  • employs no more than 9 full-time equivalent employees
  • had a turnover of £632,000 or less, or a balance sheet of up to £316,000 in the preceding and current financial year
  • is not VAT-registered
• own a vehicle that does not meet the minimum emissions standards of low emission zones, such as:
  • Euro 3 or older petrol vehicles – this generally applies to those registered before 2006
  • Euro 5 or older diesel vehicles – this generally applies to those registered before September 2015
• regularly operate this vehicle within one of the planned low emission zones

The vehicle must be one of the following:

• wheelchair-accessible taxi
• light commercial vehicle – a vehicle designed to carry goods that weigh less than 3.5 tonnes

There must also be an approved Clean Vehicle Retrofit Accreditation Scheme (CVRAS) retrofit solution available for the exact make and model.

Energy Saving Trust offers funding to cover up to 50% of the cost of retrofit solutions, with the maximum depending on the vehicle and solution chosen. You'll need to cover the remaining cost from other sources. 

Scottish microbusinesses and sole traders that operate within 20 kilometres of the Glasgow, Edinburgh, Aberdeen or Dundee low emission zones (LEZs), with vehicles that do not meet the LEZ emissions standards.

Once a grant is offered, you have 3 months to book with your chosen solution installer to have the work on your vehicle completed. You will also have to submit your claim paperwork to Energy Saving Trust within this period. 

Once your claim has been processed, Energy Saving Trust will make a payment directly to your chosen installer to cover 50% of the cost. You will then have to pay any remaining balance to the installer. 

You should not install retrofit solutions until you receive a grant offer letter.

Applicants who opt for SCR exhaust after-treatment solutions must agree to the installation of telematics. This information will be reviewed by Energy Saving Trust to monitor the success of improving air quality within the planned low emission zones. The cost of telematics will be covered by Energy Saving Trust.
