    Hello….what are the rules regarding the vessel that can be used to fill with red diesel from a garage forecourt perspective….such as gallon cans, plastic containers sort of thing….thank you. Ken

    • Alan

      Hi ken, thanks for your question regarding suitable containers for carrying red diesel.
      The answer to your question is that special containers are produced to carry fuel products from a forecourt, as long as the container is ADR approved and has a UN number moulded onto the container.
      Example UN/3H1/Y1.9/200/14/D. which is a plastic 25-litre purpose built container designed to carry this type of product.
      If you require further information you can obtain this from the ADR information site. Under Chapter 6.1 requirements for the construction and testing of packaging’s.

    Hi – Can owners of aircraft with diesel powered engines use red diesel?

    • Paul

      Hi Nigel, sure aircraft can use red diesel, but we would recommend kerosene which we also sell.

  3. Paul Smitherman

    hello team. Can you deliver close to rivers for motor boat use?

    • Alan

      Hi Paul, thank you for your question.

      Yes, we have a range of red diesel delivery tanker sizes which make it possible for us to access mooring areas. Although I must point out that red diesel cannot be used for propulsion. It can be used on boats for heating though!

      • Alex


        Just to correct the statement made above, concerning red diesel for marine propulsion.
        The vast majority of craft on the UK’s rivers and inland waterways use red diesel for both propulsion and heating supplied from a single tank aboard the boat.
        It is up to the owner to fill out a self-declaration form at the time of purchase to state the proportion of the fuel that will be used for each purpose. The supplier then uses this proportion expressed as a percentage to calculate the amount of duty to be added which is then passed on to Her Majesty’s Revenue and Customs by the supplier.
        Not all red diesel suppliers do this, I’m guessing Speedy Fuels is included in that list?

        Hope that clarifies things.

    Can I use red diesel in a vehicle classified as agricultural use only to deliver farm produce to a) another farm or b) a stable yard outside of the 1.5 km limit?

    • Alan

      Hi Ros, thanks for your questions!

      I would advise that you speak with HMRC regarding both of these questions because my answer would be NO for both of these scenarios. However, with more details customs may be able to help you further and depending on the vehicle you are using you might be able to use red diesel for these tasks.

      A) Can I use red diesel in a vehicle classified as agricultural use only to deliver farm produce to another farm?

      No, I believe you can only use red diesel to transfer produce from a farm you own to another farm that you own.

      B) Can I use red diesel in a vehicle classified as agricultural use only to deliver farm produce to a stable yard outside of the 1.5 km limit?

      No, using red diesel to travel further than 1.5 km on public roads would not be allowed. A quote from HMRC states:

      In the case of vehicles nil-licensed for limited use between different parts of land, use of public roads is restricted to passing between different areas of land occupied by the same person where the distance travelled on public roads in passing between any two such areas does not exceed 1.5 kilometres.

    Hi there, if i have a diesel powered watercraft why can i not use red deisel in it as its not powered on land? And no one owns the ocean?

    • Alan

      Hi Paul, this is a separate issue for varied countries in the world but I’m sure that the waters around each country still have laws that apply to each. You can use red diesel for the heating element but the use for propulsion is illegal. Thanks for your question Paul!

  6. Bill Kavanagh

    Hi there, do MOD vehicles, use red deisel?

    • Alan

      Hi Bill, thanks for your question.

      Yes, the Ministry Of Defence do use red diesel for their vehicles.

  7. Peter


    Can you use red diesel to power generators… For catering vans etc… Since they aren’t actually moving or for driving a vehicle?

    • Alan

      Hi Peter, yes using red diesel for generators is absolutely fine! Thanks for your question!

  8. Michael

    Hello, I’m a farmer and so I use red diesel, but when I’m coming home from my field I have to travel over 5 miles, can I still use red diesel because it is in my tank or do vosa expect me to drain my tank in the middle of the field add add white diesel?


    • Alan

      Hi Michael, thank you for your question.

      It’s a good question and hopefully helpful to many other farmers and red diesel users. Each individual should check with HMRC regarding their own situation but, I believe that you will need to pay the difference between the full rate of duty on the fuel and the rebated rate actually paid on your red diesel. For more details please contact HMRC!

  9. Owain Morgans

    Hi. If I run a diesel generator to charge my electric car on red diesel, am I breaking the law?

    As a different version of this question, if the generator was mounted on the vehicle and charging the battery as I drive along, that be illegal?

    • Alain

      Hi there,

      Thanks for your query. If the diesel itself is only being used to power the generator then you SHOULD be okay, in terms of not breaking any laws. However, since the rules of using Red Diesel are quite strict, I would recommend double checking with the HMRC before its usage. You can also find our guide to Red Diesel rules here:

      Kind Regards

    • Anth

      The generator would only output around one to three kw’s so its unlikely you would generate enough electric to power the car for very long…a good question though!

  10. Steve

    Can we use red diesel in a tractor that pulls a mower to cut a rugby pitch. The tractor never goes on the public road?

    • Alain

      Hi Steve,

      Thanks for your query! Yes – you are able to use red diesel in a tractor as long as it is not going to be used on a public road. Pulling the mower for a rugby pitch won’t be a problem!



  11. Rob

    I run a bus on private land. It runs on red diesel. However, I need to be able to blast it down th emotorway once a month to clear the emissions. How can I do this?

    • Eric Wood

      Hi Rob,

      Thank you for your comment. It would be illegal to drive your bus on the motorway if it has red diesel in the tank. If you wanted to clear the emissions from your vehicle using red diesel, you would have to drive it around your private land only. For more information, get in touch with HMRC.

  12. Rob

    Hi I just want to find out what the possible fine is if I drive I work van that has red diesel in it couldntou help please thank you

    • Eric Wood

      Hi Rob. Thanks for getting in touch. Driving a van on a public road with red diesel in the tank is a serious criminal offence. It can result in a substantial fine and your vehicle could be detained.
