FST UK Road Tax Reduction (UK)


When your FST UK H2 Assist generator has been fitted, FST UK will arrange your vehicle to be assessed by a local Vehicle and Operator Services Agency (VOSA) testing station.


We advise pre and post emissions tests to verify the difference in readings.  


Your vehicle will be producing scientifically less particulate matter and therefore emitting less Carbon monoxide, Nitrogen oxides, Benzene and Sulphur dioxides into the atmosphere.


The Test


The test usually takes between 10 - 15 minutes and is completely arranged and paid for by FST UK. Once completed the examiner will present you with certificate, it is important that you keep it safe as you will need to submit it when you reapply for road tax in the lower tax bracket.


The Process


You should apply for the reduced pollution class at the DVLA, and then reapply to tax your vehicle. This will result in a partial refund and future taxing at a greatly reduced cost. This will also increase the market value of your vehicle and make much easier to sell on.


Up to 90% fewer emissions


The reason for fewer emissions is very simple. The flame speed of Hydrogen is nine times faster than the flame speed of diesel. Burning diesel in the presence of Hydrogen will result in overall faster and more complete combustion of the original fuel. When more of the original fuel is being consumed you also burn more of the waste chemicals held within.  

  • Reduced diesel consumption of up to 36.4%

  • Minimum guaranteed fuel saving of 20%

  • Lowers engine and DPF maintenance costs

  • 65% + reduction in emissions

  • 19 week average ROI
