Delivering DERV (Road Diesel) Across the UK

DERV (Diesel Engine Road Vehicle fuel, also known as white diesel, ultra-low sulphur diesel and road diesel), is most commonly used to power road vehicles with diesel engines.

Crown Oil’s white diesel is derived straight from the refinery, meaning you’ll get your bulk supply from 1,000 – 36,000+ litres at the best possible price. You can also purchase diesel in 45-gallon (205-litre) drums if you don’t have the storage space for an onsite fuel tank.

Our DERV meets the BS EN590 specification and contains all the necessary seasonal requirements for summer & winter grades, with winter-grade fuel automatically available at Crown Oil from mid-November to mid-March.

If your business requires an onsite supply of white diesel to keep you on the road, choose Crown Oil. We’ve been a UK-wide trusted, family-run fuel supplier for over 75 years and can deliver your DERV within 24-48 hours of order.

What is DERV?

DERV, which stands for Diesel Engine Road Vehicle, is a liquid fuel product that can be used in any diesel engine but is more commonly used in on-road vehicles to keep fleets moving as well as in off-road vehicles that are no longer able to use red diesel after the fuel duty changes.

As well as being referred to as DERV, it’s also commonly known as road diesel, white diesel or simply ‘diesel’ by the vast majority of people.

What is the price of DERV?

Diesel prices fluctuate daily as a result of the global oil market, which is why we are unable to publish fixed prices online. Adding to this, other variables can impact prices, such as your required quantity and location.

Therefore, it’s always best to speak to one of our fuel specialists who can check the current prices and provide you with an up-to-date quote. Our account managers know the market inside out, so will always do their best to get you a competitive price.

Where can I buy DERV from?

DERV fuel can be bought from many oil suppliers across the UK but it’s important to choose one that offers a reliable and quality supply service. Crown Oil has over 80 tankers and fuel depots strategically located across the country, which allows us to offer some of the quickest delivery times in the industry.

As well as quality service, our diesel is derived straight from the refinery, which ensures we supply only the highest quality DERV to our customers. And finally, our large buying power allows us to buy in bulk so we can then pass on these savings to you in the form of competitive prices.

Free DERV guide

Despite its widespread use, from lifting steel beams to paving roads and digging foundations, there are some uncertainties that surround its use. With new tax changes coming in for red diesel and different fuel specifications for DERV, it can be difficult to keep track of the rules and regulations. As a UK-leading DERV supplier, we discuss this and more in our guide.

Protect DERV from thieves with Diesel Secure

Diesel Secure is an anti-theft marker dye that can be added to UK non-rebated fuel (white diesel, DERV, or road diesel), acting as a deterrent to thieves.

Since the 1st of April 2022, many businesses and applications are no longer permitted to use rebated fuel (red diesel or gas oil). This means that stored fuel now appears identical to that purchased for personal use, putting white diesel stocks at a much higher risk of being stolen.

Run out of fuel whilst out on the road? Fuel cards can help

Many businesses have the luxury of an onsite storage tank, allowing drivers to fill up onsite. However, many fleets have to rely on re-fuelling at petrol or service stations which can result in businesses paying higher prices. Our fuel cards are a popular choice by many fleet owners, providing cost savings, added security and the convenience of letting you fill up at a vast network of petrol stations around the country. Learn more by calling 0330 123 1444 today.

Can I buy wholesale diesel?

If you have the available storage facilities onsite and you’re a heavy fuel user, ordering wholesale diesel is a much cheaper option than purchasing at the pump. We also offer a wide range of other wholesale fuels, including:

Red diesel duty has changed

DERV has similar properties to other diesel fuels, such as red diesel, so it’s important to know the rules and differences in tax rates when choosing fuel.

Red diesel is a rebated fuel which has a much lower tax rate of 5% for volumes below 2300 litres. For any higher volumes, the tax rate is 20%. The rules surrounding using red diesel have now changed, with many sectors losing their entitlement from 1 April 2022.

Please note – it’s illegal to use red diesel in road-going vehicles.
