At Watson Fuels, we're proud to offer nationwide supply of HVO Renewable Diesel to businesses and farms across the UK.

All product is sourced from approved supply partners, with full certification and chain-of-custody documentation provided through the Renewable Fuel Assurance Scheme.

What is HVO fuel?

HVO stands for hydrotreated vegetable oil, sometimes known as Renewable Diesel. Part of the paraffinic family of fuels, it is a fossil-free alternative to mineral diesel, resulting in up to 90% reduction in Greenhouse Gas emissions*. It is also specially formulated to deliver a cleaner burn, and produces significantly lower NOx and particulate matter**.

Choosing this alternative fuel can help you not only reduce your overall carbon footprint, but also reduce the local emissions of your operations.

At Watson Fuels, we are committed to helping you reach net zero. Not only can we supply your HVO but you can also purchase it as Carbon Offset Fuel, which effectively counteracts the remaining CO2 emissions that you can’t reduce.

How is HVO made?

HVO is part of the paraffinic fuel family. It is a second-generation biofuel, also known as an advanced biofuel or renewable diesel, made from vegetable oils or animal fats. Unlike first-generation biofuels, these raw sources are processed using a specialist hydro-treatment to achieve high levels of purity. The result is a stable fuel with a long-shelf life and excellent performance year-round.

Who is HVO for?

HVO is a drop-in replacement for diesel. It delivers an efficient and reliable performance for vehicles and machinery across industries:

  • Construction equipment

  • Fleet vehicles

  • Agricultural machinery and vehicles

  • Manufacturing machinery

  • Industrial trucks and tankers

  • Generators

Why switch to HVO?

One key difference with HVO compared to other alternative fuels is that it is FAME-free. Its formulation gives it excellent cold weather properties, a long-shelf life and ultra-low sulphur combustion for a reliable fuel all year round.

Using HVO is an effective way to reduce the carbon footprint of your business. It is also a simple solution. HVO is a drop-in fuel replacement that has very similar properties to regular diesel, so you won’t need to drain or modify your tank. We can also work with World Kinect Energy Services to help you balance the higher price point of HVO by generating savings elsewhere in your fuel and energy supply.
