About the low emission zone retrofit fund

The low emission zone retrofit fund provides eligible micro businesses (typically with less than 10 employees), who operate within one of Scotland’s four low emission zones, with support to retrofit their existing non-compliant vehicles. This retrofit is done with clean vehicle retrofit accreditation scheme (CVRAS) approved solutions that meet the minimum standards of the Glasgow, Edinburgh, Aberdeen and Dundee low emission zones. 

Grants are available to cover up to 70% of the cost of a vehicle retrofit, subject to the following terms and conditions: 

  • Up to £6,000 per light commercial vehicle and wheelchair accessible taxi that are installing retrofit exhaust after-treatment systems. 
  • Up to £12,000 per wheelchair accessible taxi installing re-powering technology.
  • Up to £16,000 per heavy goods vehicle or refuse collection vehicle. 

If you have received funding from the low emission zone support fund within 12 months of applying, the value of the fund claim will be deducted from any grant offered for retrofit. 

If a grant is awarded and vehicle retrofitted, you must commit to running the vehicle for a period of three years (taxis and light commercial vehicles) or five years (heavy goods vehicles or refuse collection vehicles). 

If the vehicle becomes unroadworthy (including failing licencing requirements), is sold, written off or exchanged within the three to five year timeframe, you must repay a proportion of the grant. This will be based on the time remaining within the committed timeframe. 

You can apply for a maximum of three vehicles to be retrofitted.  Following the retrofit of three vehicles, you will not be eligible for further funding from either the ow emission zone retrofit fund or the low emission zone support fund.
