What is the Energy Efficiency Obligation Scheme?

The Energy Efficiency Obligation Scheme (EEOS) is a government-led initiative that promotes reduced energy consumption and improved energy efficiency throughout Ireland. Under the scheme, energy suppliers like Calor, known as Obligated Parties, support homeowners and businesses in making energy-saving upgrades such as insulation, efficient heating systems and smart energy controls. These improvements can make your home warmer, your business more efficient, and your energy bills easier to manage, all while supporting a more sustainable future.

EEOS benefits

Practical savings and smarter energy use for homeowners and businesses.

  • Lower Energy Bills

Frequently Asked Questions about the Energy Efficiency Obligation Scheme

Eligibility depends on your current energy supplier, the type of fuel you use, and the improvements being considered. If you’re a Calor customer, you may qualify for EEOS support, especially if you’ve recently switched or are planning energy upgrades. A free consultation will confirm what’s possible.
Not always. Many energy efficiency upgrades available through the Energy Efficiency Obligation Scheme (EEOS) are partially or fully funded, depending on the type of work and your eligibility. Calor will guide you through what’s covered for your home or business.
In some cases, yes. The EEOS may be used alongside other energy grants, such as those offered by the SEAI. Calor can advise you on what can be combined and how to make the most of available funding.

The EEOS for homeowners can cover energy-saving improvements such as:

  • Wall, attic, or floor insulation
  • High-efficiency boilers and heating controls
  • LED lighting
  • Smart meters and energy monitors

Calor energy advisors will assess your home and recommend the best upgrades for comfort and savings.


The EEOS for businesses can help fund improvements such as lighting upgrades, energy-efficient boilers, process optimisation, and energy monitoring systems. We’ll tailor our advice based on your site and operations.
All EEOS-supported work must be carried out by qualified, registered professionals. This ensures the work meets safety and energy standards, keeping you eligible for funding.
It varies depending on the type of upgrade, but once your consultation is complete, Calor aims to move quickly, guiding you through the assessment, approvals, and installation process. Smaller projects may be completed in weeks, while larger ones may take longer.
A BER (Building Energy Rating) is a certificate that indicates a building's energy efficiency, rated on a scale from A (most efficient) to G (least efficient). It helps you understand how much energy your home or business is likely to use for heating, lighting, and hot water. If you’re applying for EEOS support, a BER may be required before or after your upgrade to measure the energy improvements made.
You may need a BER (Building Energy Rating) before or after the work to confirm your property’s energy performance. If your BER is less than six years old and your property hasn’t had major renovations, you might not need a new one.
