Domestic Heating Oil
Hydrotreated Vegetable Oil (HVO) is emerging as a powerful solution for households seeking to reduce their carbon footprint without compromising heating performance.
As a renewable heating oil, homeowners in the UK are increasingly adopting HVO, which offers a cleaner and more sustainable fuel option than traditional kerosene or gas oil. Made from 100% renewable feedstocks, it burns cleaner, stores safely, and requires minimal system adjustments.

Key Benefits of Using HVO in Homes
Choosing HVO for domestic heating delivers a range of immediate and long-term benefits for households:
- Significant Carbon Reduction: HVO can reduce carbon emissions by up to 90% compared to fossil heating oil, helping you make a meaningful contribution to the UK's net-zero goals.
- Cleaner Burning Fuel: It produces fewer particulates and lower NOₓ emissions, resulting in better indoor air quality and reduced impact on the environment.
- Long-Term Storage Stability: HVO has an extended shelf life and resists degradation, making it ideal for seasonal heating use without fuel spoilage.
- No Odour or Smoke: Unlike traditional heating oils, HVO burns odourlessly and without visible smoke, improving comfort and air quality around your home.
- Safe and Non-Toxic: It is biodegradable and less harmful in the event of a leak or spill, offering added peace of mind for families.
How to Switch: A Simple Transition Guide
Converting to HVO is often a straightforward process, especially for homes already using oil-based heating systems. Here's how to get started:
- 1Speak with your fuel supplier: Confirm whether they provide HVO as a heating solution for domestic use.
- 2Check boiler compatibility: Many modern boilers require only minor adjustments or nozzle changes to use HVO efficiently.
- 3Flush and clean your tank: Before switching, your existing fuel tank may need to be cleaned to ensure optimal performance.
- 4Trial and monitor: Some suppliers offer test batches to assess HVO performance in your system before making a full commitment.
- 5Update service plans: Inform your heating engineer and schedule regular maintenance to maintain efficiency with the new fuel.
Boiler Compatibility: Is Your System Ready?
The good news is that many existing domestic oil boilers are either already compatible with HVO or can be adapted with minimal modifications.
Manufacturers such as Grant, Firebird, and Worcester Bosch are currently supporting HVO trials or are certified for use. Working with a qualified heating engineer ensures a smooth transition and optimisation of your system for HVO use.
In most cases:
- Older boilers may need injector and nozzle upgrades.
- Newer models often require minimal changes.
- Fuel lines, filters, and seals should be checked and rated for use with paraffinic fuels, such as HVO, to ensure compatibility and prevent issues.
Achieve Real Carbon Savings at Home
Switching to HVO doesn't just offer theoretical carbon reductions; it also provides practical, measurable, real-world benefits.
On average, households using HVO can reduce their annual carbon emissions by several tonnes, depending on usage.
Therefore, HVO is one of the most effective low-disruption paths toward decarbonising home heating, especially in rural or off-grid areas where alternatives like heat pumps may not be feasible.
FAQs for HVO Fuel
HVO fuel (Hydrotreated Vegetable Oil) is a premium-quality renewable diesel made from 100% renewable waste fats and vegetable oils. It undergoes a hydrotreatment process that removes oxygen, creating a clean-burning, paraffinic fuel that can directly replace conventional diesel.
Yes. HVO is a drop-in replacement for diesel and can be used in existing engines and heating systems with little to no modification, in most cases.
Unlike biodiesel (FAME), HVO is chemically similar to fossil diesel, so it doesn't suffer from the same storage, stability or cold-weather issues, and it can be used at up to 100% concentration.
HVO can reduce net carbon emissions by up to 90% compared to standard fossil diesel or heating oil, depending on the feedstock and supply chain.
Yes, many domestic oil boilers are already compatible with HVO or can be adapted with minor modifications, such as a nozzle change.
Yes. HVO is RTFO-compliant and recognised as a sustainable renewable fuel under UK renewable fuel regulations.
Compass Energy supplies certified HVO fuel UK-wide for domestic, agricultural and commercial customers, with flexible delivery options.
HVO typically costs slightly more than standard diesel or heating oil, though the premium has narrowed as supply has increased, and the environmental and storage benefits often offset the difference.
Yes. HVO has excellent long-term storage stability and resists degradation, microbial growth and water absorption far better than standard diesel or biodiesel.
HVO offers a substantial carbon reduction with no engine or system modifications in most cases, making it one of the easiest ways to decarbonise without disrupting your operations.
HVO is produced by hydrotreating waste fats, used cooking oils and vegetable oil residues, removing oxygen and impurities to create a stable, paraffinic hydrocarbon fuel.
Compass Energy's HVO is sourced from certified sustainable waste and residue feedstocks, not virgin palm oil, in line with RTFO sustainability criteria.
HVO has excellent cold-weather performance, with a lower cloud point than standard diesel in many formulations, reducing the risk of waxing in low temperatures.
Yes. HVO is non-toxic, biodegradable and safer to handle and store than fossil diesel, with reduced risk in the event of a spill or leak.
HVO's eligibility for tax treatment and carbon reporting depends on current UK fuel duty and RTFO rules — speak to our team for the latest guidance relevant to your business.
