Is now the best time to switch from oil heating in Ireland?

18/05/2026 15 min

For years, oil heating has been the default for many Irish homes, particularly outside urban areas. It’s familiar, widely available, and for a long time, it simply did the job. But for a growing number of homeowners, that’s no longer enough. Across Ireland, people are starting to take a closer look at how their homes are heated. Sometimes it’s prompted by an aging oil boiler coming to the end of its life. Sometimes it’s rising running costs or the hassle of managing deliveries. And sometimes it’s part of a bigger conversation around home upgrades, insulation and energy efficiency. There’s also a wider global shift happening. Energy no longer feels like something you can set and forget. Between changing prices, supply uncertainty and increasing focus on sustainability, more households are thinking ahead. For many, that raises a practical question: If you were choosing your heating system today, would you still choose oil?

Why Irish homeowners are reconsidering oil heating

For most homeowners, the move away from oil isn’t driven by one single issue. It’s usually a combination of everyday realities.

Oil heating systems often require more active management. Tanks need to be checked. Deliveries need to be timed. Running low can quickly turn into an urgent situation, especially in colder months.

There’s also the question of system age. Many oil boilers in Irish homes are now 15–25 years old. While they may still be working, they’re often less efficient than newer alternatives and more costly to run over time.

At the same time, expectations have changed. Homeowners are looking for:

  • More consistent heating performance
  • Greater control over usage and supply
  • Systems that align with modern efficiency standards

Sustainability is part of the conversation too, but for many, it’s not the only driver. It sits alongside practicality; how easy the system is to live with day to day.

For off-grid homes in particular, the focus is shifting from “this works for now” to “is there a better, more sustainable way to heat my home for the long-term?”

How global energy trends are shaping heating choices

Energy markets have always been influenced by global factors, but in recent years, that impact has become more visible at a household level.

Changes in supply, shifts in demand and international events can all influence how fuels like oil are priced and distributed. For homeowners, that can translate into:

  • Less predictable pricing
  • More sensitivity to external events
  • A greater need to plan ahead

As a result, there’s a growing awareness of energy security. People are asking:

  • Can I rely on this system long-term?
  • How exposed is it to external changes?
  • Do I have control over how and when I use energy?

This doesn’t mean everyone is switching immediately. But it does mean more homeowners are exploring options that offer greater stability and flexibility over time.

What are the main alternatives to oil heating in Ireland?

When it comes to moving away from oil, there isn’t a single replacement that suits every home. The right choice depends on property type, insulation, location and how the home is used. Here’s how the main options compare:

Heat pumps

Heat pumps are often discussed as a long-term low-carbon solution, but they’re not suitable for every home. They typically require a high level of insulation and, in many cases, upgrades to radiators or underfloor heating. 

LPG (Liquefied Petroleum Gas)

LPG offers a more direct transition from oil. It works in a similar way, delivering central heating, hot water and cooking from a single fuel source. For many off-grid homes, LPG fits more easily into existing systems, meaning:

  • Less disruption during installation
  • Familiar heating controls and performance
  • A practical upgrade rather than a full system overhaul

BioLPG

BioLPG is chemically identical to LPG but produced from renewable feedstocks. The key advantage is that it can be used in the same systems without modification.

This allows homeowners to:

  • Switch away from oil now
  • Transition to renewable gas over time
  • Avoid replacing systems again in the future

Hybrid Heating Systems

Some households combine technologies, for example retaining part of an existing system while introducing a newer one. This can help spread cost and reduce disruption, but may not always deliver the same efficiency gains as a full switch.

Is LPG a practical alternative to oil heating?

For many homes across Ireland, particularly in rural areas, LPG is one of the most practical alternatives to oil.

One of the main reasons is how easily it fits into existing setups. In many cases, switching from oil to LPG doesn’t require a complete redesign of the heating system. That makes it a more realistic option for homes that aren’t suited to more extensive upgrades.

There’s also the day-to-day experience to consider. With LPG:

  • Heating is responsive and consistent
  • Supply is planned and managed, rather than reactive
  • Delivery infrastructure is well established nationwide

For homeowners used to oil, the difference is often less about how the system works, and more about how easy it is to live with.

Calor Gas Ireland has built a nationwide network supplying LPG to homes, farms and businesses, particularly in off-grid areas where reliability matters most. That infrastructure plays a key role in making LPG a dependable option.

What are the benefits of switching from oil to LPG or BioLPG?

Switching from oil to LPG or BioLPG brings a number of practical advantages that show up in everyday use.

LPG is a cleaner-burning fuel, which can help reduce emissions compared to oil while maintaining strong heating performance.

It also offers:

  • Fast, responsive heating
  • Consistent temperature control
  • The ability to power multiple appliances from one source

From a longer-term perspective, BioLPG adds flexibility. Because it works within the same system, homeowners can reduce their carbon footprint over time without replacing their heating setup again.

Another key benefit is control. With LPG, households can plan supply, monitor usage and avoid the last-minute pressure that often comes with running low on oil.

What should you consider before switching?

Switching heating systems is a significant decision, and it’s important to approach it with a clear understanding of your home

  • Property type

    Rural and off-grid homes often benefit most from LPG due to the lack of connection to the natural gas network. Space for a tank and access for delivery are key considerations. 
  • Insulation levels

    A well-insulated home will always be more energy efficient, regardless of the heating system. Improving insulation can make a noticeable difference to performance and running costs. 
  • Existing heating system

    Some homes may only need minor upgrades, while others may require a more significant change. Understanding what’s already in place will help guide the right decision.
  • Long-term energy planning

    Rather than focusing only on immediate needs, it’s worth considering how your heating system will perform over time. Reliability, flexibility and future options all matter when making a long-term investment.

Is now the right time to make the switch?

There isn’t a universal answer, but there is a clear shift in how people are approaching the question. For some, the trigger is practical; an older boiler, rising costs, or the hassle of managing oil. For others, it’s about planning ahead and making a more informed choice about how their home is heated in the long term. What’s changed is the mindset. Homeowners are no longer just maintaining what they have, they’re actively evaluating whether it still makes sense. And for many, that evaluation is leading them to explore alternatives like LPG and BioLPG.

How to get started with switching your heating system

The first step is getting a clear picture of your home and how you use it.

Look at your current system, how well your home is insulated, and what you need from your heating day to day. That quickly helps narrow down what options are realistic.
