What is red diesel?

Red diesel is the term used for low-duty gas which is only legally allowed to be used in off-road vehicles and machinery. Red diesel is the same as regular diesel, but it has a red dye added into it to prevent the illegal use of it in on-road vehicles.

Where to get red diesel?

Birlem Oil is a national red diesel supplier to businesses across the UK. We deliver red diesel from our oil depots across the country, directly to your site within 24-48 hours of order. Our drivers tend to stick to the same delivery routes so you’ll always see a familiar face. Plus, you’ll be assigned a dedicated account manager who will look after your red diesel needs from the outset.

How much is red diesel?

Red diesel price fluctuates in price much like other gas and oil prices. The price is very much dependent on the global oil market, as well as the quantity and location of where the diesel is being delivered.

The price of red diesel is cheaper than standard white diesel due to the tax reduction that customers are allowed when paying for red diesel.

No matter what time you call us or what your needs might be, we are dedicated to delivering your gas oil with a professional and proficient service.

Call us today on 020 8801 5497 for a delivery of red diesel fuel you can count on.

Barrel or bulk quantities available

We understand every customer’s needs differ, so for that reason, we supply red diesel from 205-litre barrels to 36,0000 litres and more. We have baby tankers and large tankers on hand, equipped to provide bulk deliveries in one single journey. If you would like to save money on your purchase of red diesel and you have the storage facility, you can do so by buying in bulk.

9 out of 10 orders delivered next day

With depots located throughout the UK, we are able to provide you with some of the quickest delivery times in the industry. Thanks to our 30+ years experience, we have risen quickly to become the number one choice for red diesel. Our primary goal is to ensure your red diesel is with you in no time at all.

Need an urgent red diesel top-up?

Don’t worry, your operations will be backpowered in no time. We understand the importance of gas oil for businesses, with many of our customers relying on the fuel to power backup generators. That’s why we offer same day and next day deliveries for when you need us the most. We even provide emergency red diesel deliveries for when you need fuel in a matter of hours to prevent business interruption.

In a remote location?

Many of our customers live and operate in rural, out-of-town locations that are inaccessible by our larger tankers. As so, we have a network of supply locations throughout the UK and a wide range of tanker sizes capable of navigating tight and bendy roads, in order to deliver your red diesel to even those isolated locations.

Can I still buy red diesel?

As of the 1st April 2022, red diesel is restricted to operations such as farming and forestry, in line with new rules set out by the UK government. This means those affected will need to switch to more costly white diesel, which carries the full fuel duty rate. To summarise, red diesel is still permitted for use: in agriculture, fish farming, forestry and horticulture; non-commercial heating and power generation; rail transport, marine transport, boating and sailing; circuses and other travelling fairs; and sports clubs including golf courses.

Red diesel law

Red diesel is used solely in off-road vehicles and machinery and is popular in the agricultural, marine, rail and construction industries. To find out what vehicles can use red diesel, HMRC has a full list here or give our friendly team a call on 020 8801 5497 for expert advice.

Red diesel attracts a lower rate of excise duty than road diesel and contains chemical markers to give it the red colour so it can be distinguished from fuel where excise duty is required. The marker will stain the fuel tank and if caught breaking the red diesel law, you can be fined and your vehicle detained.

Why has red diesel duty changed?

The new red diesel rule changes are part of the Government’s 2050 net-zero decarbonisation plan, aimed at encouraging the wider use of white diesel and lower-emission fuels in the commercial sector, particularly construction, plant, logistics and highway maintenance.

Carbon offset red diesel

Birlem Oil is conscious of protecting the environment and is committed to a greener future. We are well aware that many businesses are now attempting to improve their own green credentials too, which is why we offer a carbon offset fuel.

Our Carbon Offset Red Diesel is the exact same fuel, so you will not need to make adaptions to your equipment to use it. What makes it an eco-friendly alternative is the carbon dioxide emissions released into the air.

When using the fuel, your carbon emissions are matched by the purchase of carbon credits on your behalf. For only a small additional cost at the time of purchase, you can offset the carbon emissions from your fuel use now. To find out more call us on 020 8801 5497.

Does red diesel go by any other names?

Red diesel goes by a variety of names including; 35-second oil, tractor diesel, marine diesel, generator diesel, gas oil and BS 2869.
