Plant and Machinery Allowance (PMA): First Year Allowance (FYA): expenditure on natural gas and hydrogen refuelling equipment


Expenditure on new plant and machinery installed at a gas refuelling station to refuel vehicles with natural gas, biogas or hydrogen fuel can qualify for 100% FYAs. The refuelling station does not need to be open to the public, or used for cars. For example, an operator of a fleet of commercial vehicles may install a gas refuelling station on its premises to refuel its vehicles. The costs could qualify for FYAs.

Biogas equipment qualifies from 1 April 2008 onwards.

Eligible equipment can include:

  • storage tanks;
  • compressors;
  • controls and meters;
  • gas connections; and
  • filling equipment.


The expenditure must be incurred between 17 April 2002 and 31 March 2015.

Biogas is gas produced by the anaerobic conversion of organic matter and used for propelling vehicles. It is a substitute for natural gas.

The legislation is in FA02/S61 and FA02/Sch20, which inserts a new Section 45E into CAA01. The legislation was amended by FA 2008, which added biogas, and FA2013, which extended the time when expenditure must be incurred to qualify for this 100% FYA to 31 March 2015.
