What is the position with the DVLA regarding my vehicle being converted to LPG?
You have to notify the DVLA that your vehicle has been converted to run on LPG in addition to petrol. There is a section in your V5 Registration Document for you to fill in and send to them. Some vehicles may obtain a reduction in the annual vehicle tax fee. To qualify the car has to meet Band 4 (40% improvement on Euro IV) emissions targets.
