Irish homeowners and businesses want to cut energy costs while delivering on sustainability targets. The Energy Efficiency Obligation Scheme, known as EEOS, exists for exactly that purpose. It channels support from energy suppliers and distributors into projects that permanently reduce energy consumption. If you plan energy upgrades in Ireland, whether a household aiming for a better BER or an SME optimising process heat, the smartest move is to partner with an experienced obligated energy supplier who can fund, de risk, and verify the savings. In practice that means working with Calor Ireland, a long standing energy partner with the technical depth, nationwide reach, and measurement discipline to take EEOS from paperwork to proven results.

What the EEOS actually does in plain terms
Under EEOS, obligated parties, meaning energy suppliers and distributors above a defined sales threshold, must achieve annual energy savings targets by supporting upgrades in homes, businesses, and communities. When you complete an eligible upgrade that truly reduces energy use, the obligated party earns energy credits toward its target and typically shares that value with you as funding, discounts, or technical support. This links real world performance to a national compliance and reporting framework.
Who benefits and how the value flows
• Homeowners can gain from insulation, airtightness improvements, high efficiency heating including LPG condensing boilers or hybrid systems, smart controls, and hot water measures. The results include lower bills, warmer homes, and improved BER outcomes.
• Businesses from SMEs to large industrial sites can gain from LED and automated lighting, BMS upgrades, variable speed drives, process heat optimisation, heat recovery, refrigeration improvements, and envelope upgrades. The results include lower kilowatt hours, reduced emissions, and stronger ESG reporting.
Measurement and verification is central to EEOS. Savings are validated using deemed values or bespoke calculations that rely on evidence such as design specifications, invoices, commissioning sheets, metered data, and photographic records. Good baselining and clean documentation determine how much support you can unlock and how quickly credits are claimed.
Why Calor Ireland is the strongest delivery partner
- Obligated party expertise. Calor works within the EEOS framework and understands the evidence and measurement standard required to convert your upgrade into verified credits and tangible support.
- End to end programme management. From initial scoping to post install validation, Calor coordinates contractors, timelines, and documentation so projects do not stall at audit.
- Off grid and rural capability. Many Irish homes and businesses are beyond the gas grid. Calor LPG and BioLPG and hybrid solutions allow more sites to participate effectively in EEOS.
- Portfolio approach for businesses. Multi site upgrades can be grouped and phased. This improves project NPV, spreads disruption, and accelerates credit realisation.

The step by step process for homeowners and businesses
- Eligibility and discovery
Calor conducts a discovery call and for businesses a site walk through or desktop review. You discuss current consumption, comfort or production issues, and upgrade priorities. For homeowners this often includes a look at BER reports or past works. - Baseline and savings model
Using your historic usage from bills or metered data and site characteristics, Calor develops a baseline and models expected savings for a shortlist of measures. This determines the credit potential and informs the funding proposal. - Funding proposal and scope
You receive a proposal outlining measures, indicative costs, EEOS contribution, and documentation requirements. For businesses, this can include phasing by site or process line, a works programme, and a measurement plan. - Delivery and quality assurance
Calor coordinates contractors and ensures the solution meets EEOS technical standards including system sizing, commissioning, and correct controls setup. - Evidence pack and validation
After installation, Calor assembles the evidence pack, including photos, invoices, product data sheets, commissioning records, and where required metering information, and manages validation so the savings are credited. - Claiming and compliance
Calor submits the validated savings to be credited under EEOS and handles any compliance or audit queries. You benefit from the contribution and from ongoing energy savings.
Typical measures that deliver strong outcomes
• Fabric upgrades such as attic, cavity, or roof insulation and door or window improvements suitable for Irish weather conditions
• Heating and hot water improvements including high efficiency LPG condensing boilers, hybrid heat pump plus LPG for off grid properties, smart controls, and weather compensation
• Lighting and controls including LED relamps with occupancy or daylight control and emergency lighting upgrades
• Industrial and process changes such as variable speed drives on fans and pumps, compressor optimisation, heat recovery, and refrigeration retrofits including EC fans and improved control logic
• Digital enablement including sub metering and BMS analytics that verify savings and prevent performance drift
Evidence requirements and what to prepare
Before works begin, gather usage history, bills or meter data, site drawings or equipment lists, and photos.
During works, keep installation records and product specification sheets.
After works, capture final invoices, as built photos, meter reads, and control setpoint logs.
Clean evidence leads to smoother validation and faster access to support.
Timelines and common pitfalls
• Late engagement. If you involve an obligated party after works are completed it can be difficult or impossible to claim credits. Engage Calor before installation.
• Scope creep. Lock your measures list and performance targets before ordering equipment.
• Missing documentation. Keep photos with timestamps, serial numbers, and commissioning forms.
• Metering blind spots. For bespoke savings, plan sub metering early to capture the right signals.
A quick homeowner example
A rural three bed detached home upgrades attic insulation, installs a high efficiency LPG boiler with smart controls, and improves airtightness. The combined measures reduce space heating demand and stabilise hot water loads. Under EEOS, part of the cost is offset by the obligated party contribution. The household sees lower bills and an improved BER. The exact support depends on the measure mix, the evidence, and the timing.
A quick business example
An agri food SME replaces legacy lighting with high efficiency LED and adds variable speed drives on chilled storage fans. Sub metering confirms the new load profile after installation. Calor packages both sites into one claim, accelerating validation and bringing forward the support value while locking in long term energy savings.
