How to become a gas installer in Ireland with Calor

Why choose a career as a gas installer?

If you’re weighing up your options, here’s why gas installation is an attractive and future-ready choice.

1. Strong Demand & Job Security

Ireland’s housing stock is among the oldest in Europe, meaning many homes will need boiler upgrades or full heating system replacements over the next decade. Meanwhile, with government policy pushing toward low-carbon energy, many properties (especially rural ones) are adopting LPG or BioLPG systems.

Trades like plumbing, heating and retrofit are already among the “most in-demand” in Irish construction and energy sectors.

Because installing gas or fuel systems is safety-critical and cannot be automated, your skills remain essential even during economic slowdowns. That translates into stable, resilient income, whereas many desk roles are more vulnerable to automation.

2. Flexibility in How You Work

Gas installation offers multiple career routes:

• Join an established heating or energy company for stability.
• Work as a contractor on short- or long-term projects.
• Set up your own business and build your client base.

For students or people looking for side income, the flexibility means you could start part-time and scale up. It’s a low barrier to entry into your own micro-business that can expand over time.

3. Competitive Earnings

Trades are in demand across Ireland, and skilled installers command strong rates. Registration costs are modest. RGII fees are around €91 to apply and €245 annually and most installers recover this through their first few jobs. From there, it’s a career with excellent returns.

While pay varies depending on location and experience, gas installation consistently offers higher earnings than many careers with similar entry requirements, making it a well-paid and sustainable trade.

And when you work with Calor, the earning potential goes even further. Installers receive €300 for every converted lead they bring to Calor, plus a bonus of €500 when they reach five successful conversions. It’s our way of rewarding initiative and recognising the value our installers bring to both their customers and the Calor network.

4. A Future-Focused Career

Energy in Ireland is evolving and so is the role of the modern gas installer. Today’s professionals aren’t just fitting traditional systems; they’re helping homes and businesses make the switch to cleaner, lower-carbon fuels.

With Calor BioLPG, installers can offer customers a renewable option that works seamlessly with existing LPG systems. There’s no need for equipment changes or modifications, as BioLPG can be used as a full or partial blend with conventional LPG.

For many homeowners, particularly those switching from oil heating, this makes the transition to cleaner energy simple and affordable. Every new customer who converts from oil to Calor automatically receives a 10% BioLPG blend, instantly reducing their carbon footprint without any extra effort or cost.

By helping customers move away from oil and towards renewable gas, installers are playing a vital role in Ireland’s journey to a lower-carbon future while gaining valuable, future-ready skills in sustainable energy.

So, how do you get started on this career path and join the growing community of installers leading Ireland’s energy transition?

Steps to becoming a registered gas installer in Ireland

To work as a gas installer, you need to be recognised by the Register of Gas Installers of Ireland (RGII). This ensures that every installer meets safety and quality standards.
Here’s how the typical process works:

Training & Qualifications

• Complete a recognised gas installer training programme. These combine classroom learning with practical, hands-on skills.
• Training covers everything from boiler installation and servicing, to safety procedures, regulations and compliance with Irish energy standards.
• Courses are available across Ireland and are suitable for school-leavers, apprentices, or those retraining from another field.

Apply for RGII Registration

• After training, you can apply to register with RGII.
• Registration proves that you are competent, qualified, and authorised to work safely with gas appliances.
• The process involves submitting your qualifications, proof of experience, and agreeing to work to RGII’s strict safety code.

Ongoing Professional Development

Gas installation is a safety-critical trade. That means the learning never really stops. Installers must keep up with new technologies, regulations, and safety updates through Continuing Professional Development (CPD). This ensures you stay compliant and confident in your work.

You can learn more about the process directly from RGII.

What does a typical day look like for a gas installer?

It’s one thing to know that gas installation is in demand but what does the job actually involve day to day? Here’s a closer look at the reality of life as a gas installer in Ireland.

Gas installers carry out a mix of:

• New installations: fitting boilers, LPG or BioLPG tanks, heating systems, and appliances.
• Servicing and repairs: keeping systems running safely and efficiently, fixing issues, and responding to callouts.
• Safety checks: inspecting appliances, testing for leaks, and ensuring installations comply with RGII standards.
• Customer support: advising homeowners on energy use, upgrades, or switching to renewables like BioLPG.
  

No two days are the same. One morning you might be working in a rural cottage, the next in a new housing development or small business. For many installers, the variety and problem-solving are what make the role so rewarding.
