DERV Fuel Guide – Learn More About DERV Road Diesel Fuel
DERV is a fuel that is used to power on-road vehicles – it stands for Diesel Engine Road Vehicle, but is also known as road diesel and white diesel, among other names.
DERV, also known as diesel fuel, is a popular choice across many industries with 25,103 billion litres of diesel sold in the UK in 2020 alone. That’s because it’s capable of carrying out some of the world’s most demanding work, from lifting steel beams to paving roads and digging foundations.
Despite the widespread use of DERV, there are some uncertainties that surround the fuel’s use, including its tax and price. Crown Oil is a leading bulk DERV supplier with almost 75 years of history supplying UK businesses with millions of litres of DERV every year, so our fuel experts are well placed to discuss this and more below.
What is DERV?
DERV is Diesel Engine Road Vehicle fuel that’s used to power equipment, as well as anything with a diesel engine, such as cars, vans and lorries; as well as boats, ships, trains and many other types of passenger vehicles. Other common names for DERV include white diesel and road diesel.
DERV uses the compression ignition engine, named after its inventor, Rudolf Diesel.
Before the discovery of crude oil distillation, Rudolf originally designed his engine to use coal dust as fuel and also trialled vegetable oil – a concept that eventually influenced biodiesel and HVO fuel production today.
Are there any other names DERV is known by?
Yes, you may have heard DERV referred to as;
- Road diesel
- Road DERV
- White diesel
- Ultra-low sulphur diesel (ULSD)
Although DERV is known by a few different names, they all refer to the same fuel.

How much is DERV?
Due to the daily changes from the global oil markets, it’s not possible to publish fixed DERV prices online as the cost varies daily due to influences such as conflicts in oil producing countries such as in the Middle East and other influencing out of our control.
Other factors include include the location of the customer requesting a fuel quote and the amount of fuel they wish to purchase. All of which can have an impact on the price of the fuel being ordered.

What is DERV used for?
DERV is used to power road vehicles, and in theory, can be used in any diesel-powered engine, however it’s more commonly used in lorries, HGVs (Heavy Goods Vehicles), LCVs (Light Commercial Vehicles), vans, trains, buses and coaches.
DERV sees prevalent use in businesses that operate vehicle fleets that transport goods over both long and short distances.
What is the tax rate on DERV?
DERV carries a VAT rate of 20%. Vehicles with lower emissions, such as liquefied petroleum gas (LPG), compressed natural gas (CNG) and electric vehicles are taxed at lower duty rates.
UK fuel duty is currently 52.95 pence per litre for diesel.
|Fuel type (road fuel)||Fuel duty||*Rates from 23 March 2022|
|Ultra-Low Sulphur Diesel||57.95 ppl||52.95 ppl|
|Ultra-Low Sulphur Petrol||57.95 ppl||52.95 ppl|
|Bioethanol||57.95 ppl||52.95 ppl|
|Biodiesel||57.95 ppl||52.95 ppl|
|Liquefied petroleum gas||31.61 p/kg||28.88 p/kg|
|Natural gas||24.7 p/kg||22.57 p/kg|
DERV has similar properties to gas oil (red diesel), so it’s important to know the rules and difference in tax rates. Red diesel is currently a rebated fuel so has a much lower tax rate of 5% for volumes below 2,300 litres. However, the Chancellor announced at Budget 2021, that red diesel tax is also being scrapped for a number of industries which means businesses will soon have to opt for DERV or cleaner-burning fuels such as HVO. Read more on the change in red diesel tax here.
Fuel duty has also been frozen until the end of the 2021/22 financial year, which means that it will have been frozen for at least a decade, the longest freeze for over 40 years.
*At Spring Statement 2022, the government announced that rates of Fuel Duty will be temporarily reduced for 12 months.
How can I store DERV safely?
DERV should be kept in a dedicated storage tank that’s located in a cool and dry place. This is to help prolong its shelf life and reduce the risk of contamination.
Permanent onsite storage steel tanks are commonly used to store diesel, or portable 45-gallon drums if fuel users need to easily transport DERV or don’t have the fixed storage facilities.
There is actually a legal limit on how much DERV you can store as it presents a risk to both yourself and the environment. When handled incorrectly, it’s a dangerous and highly flammable substance. Different regulations apply depending on where you’re storing DERV, how much you’re storing and what you’re using the fuel for.
Read more on this in our dedicated Oil Tank Storage Regulations Guide.
How long can DERV be stored in a storage tank?
Providing good tank maintenance and the storage conditions discussed above, DERV can be stored for between 6 and 12 months. If you’re storing diesel for any longer, it’s important to invest in regular fuel testing by a professional company to help reduce the risk of contamination.
Can DERV become contaminated?
Diesel fuel contains 7% FAME (Fatty Acid Methyl Esters) as it’s a practical necessity for suppliers to meet their RTFO obligations. However, this makes DERV highly vulnerable to microbial attack (contamination) when in storage.
FAME is hygroscopic and attracts water, which creates the perfect breeding conditions for diesel bug, sludge, and biomass to grow. This significantly reduces the quality of DERV and leads to clogged filters and engine breakages.
Can contaminated DERV be treated?
At Crown Oil, we offer fuel polishing to customers when their stored diesel has only a small amount of contamination in it. Fuel polishing essentially cleans DERV using a fixed polishing unit and can be done with little to no disruption in your operations.
However, if DERV is highly contaminated with diesel bug, then fuel polishing will not be suitable and we can instead uplift your fuel and supply a fresh batch of DERV straight into your tank. We would usually conduct a tank clean too to remove any sludge or biomass that has occurred when storing contaminated DERV.
What should I do if DERV has leaked or spilled?
If your DERV has spilled, you must act fast. If it’s only a small amount of DERV, you can use a spill kit to help contain the oil. We supply these at Crown Oil, as well as a wide range of additional ancillary products to help with the safe storage and handling of fuels.
If the DERV cannot be contained using a spill kit, you must contact a specialist as soon as possible to help avoid further damage to the environment and potentially harming wildlife or anyone nearby. DERV spills can cost tens of thousands of pounds in remedial and legal implications.
What sustainable alternatives are there to DERV?
Hydrotreated Vegetable Oil (HVO fuel) is a 100% renewable diesel fuel that’s produced from fully renewable and sustainable materials such as vegetable oils. As a paraffinic diesel fuel, it is virtually chemically identical to DERV, so can be used as a drop-in alternative without engine modification or additional infrastructure.
Using a sustainable alternative in place of DERV offers many benefits, including:
- 100% renewable, sustainable and biodegradable
- Reduces up to 90% of net CO2 emissions
- Reduces notifiable NOx, CO and PM emissions
- Up to 10 year storage life
- Can be used as a direct diesel replacement
- Year-round performance
- FAME and ester-free
- Odourless, and free from aromatics, sulphur and metals
