HVO vs diesel: what UK businesses need to know
As pressure grows around emissions, compliance and sustainability, more businesses are exploring alternatives to standard diesel. HVO (hydrotreated vegetable oil) is one of the most talked about options. But how does HVO vs diesel really compare in real-world use, and where does HVO actually make sense?
HVO vs diesel: what’s the difference?
The key difference between HVO and standard diesel is how the fuel is produced. Diesel is a fossil fuel refined from crude oil. HVO is a renewable fuel produced by hydrotreating waste oils and fats.
What is hydrotreating?
Hydrotreating is a refining process that uses hydrogen under high temperature and pressure to remove impurities such as sulphur, nitrogen and metals from fuels like diesel, petrol and jet fuel.
In day-to-day use, the two fuels behave very similarly. HVO is a drop-in alternative, meaning it can replace diesel without requiring major changes to vehicles or infrastructure.
Key differences at a glance:
- Feedstock: HVO is produced from renewable waste materials
- Carbon impact: HVO produces up to 90% less CO2 emissions.
- Compatibility: Both suitable for diesel engines (HVO as a drop-in)
- Cost: Diesel typically lower.
Using HVO in diesel engines
HVO can be used in most modern diesel engines without modification, although it is always worth checking manufacturer guidance. Because it is a drop-in fuel:
- No engine changes are usually required
- Existing storage tanks and infrastructure can be used
- It can be blended with standard diesel if needed
This makes HVO one of the simplest alternative fuels to introduce into existing operations.
Is HVO worth it for your business?
Whether HVO is worth it depends on your priorities. For businesses focused on reducing emissions, HVO offers a clear advantage. It can deliver a significant reduction in lifecycle carbon emissions compared to standard diesel, while also producing fewer NOx and particulate emissions, helping to improve local air quality.
Beyond emissions, HVO also brings a number of practical benefits. It has a longer shelf life than traditional biodiesel fuels, performs reliably in cold conditions, and is readily biodegradable, making it less harmful in the event of a spill. However, these benefits come at a higher cost per litre. HVO is often the right fit where:
- Emissions reduction is a priority
- Carbon reporting or ESG targets are in place
- Contracts require lower environmental impact
- A low-disruption solution is needed
Where cost control is the main driver, diesel will often remain the more practical choice.
Making the switch to HVO
Switching to HVO does not need to be an all-or-nothing decision. Many businesses introduce it gradually, for example:
- At a single site
- Across part of a fleet
- Within specific machinery or generators
This allows for a practical assessment of performance, cost and suitability before wider rollout.
Buying HVO fuel in the UK
HVO is available at selected forecourts, but most businesses purchase it in bulk for operational consistency. When buying HVO fuel in the UK, key considerations include:
- Reliability of supply
- Fuel quality and certification
- Delivery flexibility
- Ongoing supplier support
For most operations, consistency and service matter just as much as price. OilMaxx supplies bulk HVO through a network of local depots, helping businesses maintain reliable access to fuel with responsive, local support.
Choosing between HVO and diesel
HVO offers a practical route to reducing emissions without changing vehicles or infrastructure. Diesel continues to provide cost efficiency and remains essential across many sectors. For most businesses, the decision is not about choosing one over the other. It is about understanding where each fuel fits within your operation.
HVO is already being used across construction, transport and agriculture as a low-disruption way to lower emissions. It is not about replacing diesel overnight, but about making informed decisions based on how your business operates today and where it is heading next.
