How do I tell DVLA I have converted my car to run on LPG?

There should be a section on the registration document (V5) which allows you to detail the change and then you send it back to DVLA. They will then send out a new V5 with the updated information on it.

Fill in Section 7 of the V5 (Blue section), changing the fuel type to LPG/Petrol. Send the V5 to DVLA, they will either issue a new V5 reflecting the new fuel or request further details.

Does an LPG conversion reduce road tax?

Just done my Astra last month.

In section 7 write "LPG" in Type of Fuel and also write "Alternative Fuel" in Taxation Class.

Take your V5 to your local DVLA office along with your current tax disk and insurance docs. They will fill in the form they need for DVLA and give you a new tax disk there and then.

There is a reduction in the road tax. For my Astra (155 G/Km) the reduction was £20/yr (pro rata) which is refunded by cheque from DVLA. The even bigger saving though for people who live/work near London is that you will become exempt from the conjestion charge of £8 per day! Unfortuneatly I live in Sunderland and haven't been to London for about 20 years so don't get that saving.

edit

Just checked my new V5 and noticed that although "LPG" was acceptable on my changes section, they actually write "Gas Bi-Fuel" on the new V5 as Type of Fuel:(

Thanks , I'll get that done.

And don't forget that all important document; your official LPG conversion certificate from the approved LPGA converter because they are not going to take your word for it that you have had it done!

ooooh, I dont have that - yet. I know theres stuff in the post relating to the conversion. I'll hold sending the V5

hello

Just a quick thanks to all who helped. I'm new to driving on LPG autogas, its really does save a fortune at the pumps! £23.50 for a full tank when I'm used to paying £70. All docs and certificates on their Way to DVLA, but I'll be surprised if I receive a cheque for the car tax rebate. I only renewed the tax 1 year in September.

I would have recommended a personal visit to your local DVLA office if that was practical as they helped me fill in the forms and get everything right. New disk was handed straight to me.

Mine was a new car, converted immediately, but it was about a month and a half before I found time to sort out the DVLA forms. My tax reduction was £20/yr and I received a cheque back within about 3 weeks for £16.67 which covers 10 months reduced tax, so they do refund it at the correct rate.

As I said earlier, the real big saving for those near London can be as much as £40 per week as LPG cars do not pay the congestion charge. Filling a tank is far cheaper as you say, but be aware your mpg will be reduced also, so the saving isn't quite as big as it first appears. My mpg went down from about 28mpg to 22mpg
