Red diesel, also known as gas oil, is a vital fuel for UK farmers, used to power tractors, combine harvesters, generators, and other agricultural machinery. Its lower tax rate makes it a more affordable option for essential off-road work, but it comes with strict rules and responsibilities. Delivering red diesel safely, legally, and reliably is crucial
for farm operations.
What is Red Diesel?
Red diesel is regular diesel with a red dye and chemical marker added to it. This dye distinguishes it from standard (white) road diesel and ensures that it’s only used for approved purposes. In the UK, red diesel is taxed at a significantly lower rate to support industries like agriculture, forestry, and marine services. However, using it in unapproved vehicles or activities is illegal and can result in heavy fines or vehicle seizure.
Who Can Use Red Diesel?
As of April 2022, UK government changes to red diesel entitlement limited its use to specific industries. Fortunately for farmers, agriculture remains a permitted sector. This means you can legally use red diesel for:
-
Agricultural vehicles (tractors, harvesters, sprayers)
-
Machinery used in fieldwork
-
Heating of agricultural buildings (such as barns or greenhouses)
-
Some types of power generation on farms
However, use on public roads is tightly controlled. For example, you may only drive on roads between fields or to transport equipment if the use is directly related to agricultural work.

Legal and Safety Requirements
Before ordering red diesel, ensure you’re storing it legally and safely. UK environmental regulations require:
-
Bunded tanks (double-walled) for outdoor storage over 200 litres
-
Spill prevention equipment and safe access areas
-
Regular tank inspections for leaks or wear
-
Clear signage and labeling of red diesel tanks
You’ll also need to keep accurate records of red diesel deliveries and usage in case of an HMRC inspection.
Ordering Red Diesel
To order red diesel for your farm:
-
Choose a reputable supplier—preferably one with agricultural fuel experience.
-
Estimate your usage—take seasonal demand into account.
-
Check access routes—ensure delivery trucks can reach your fuel storage area.
-
Confirm tank compliance—make sure your storage meets environmental standards.
-
Place your order early—especially before peak seasons like planting or harvest, when demand spikes.
Some suppliers offer price-locking contracts or fuel clubs to help reduce costs, especially for small or medium-sized farms.
Conclusion
Red diesel is an essential fuel for UK agriculture, and reliable delivery is a cornerstone of modern farm logistics. By working with experienced suppliers, maintaining compliant storage, and staying informed about usage rules, farmers can ensure uninterrupted operations, avoid penalties, and keep fuel costs manageable. In today’s regulatory and economic climate, partnering with a dependable red diesel delivery service is more important than ever.
