The Energy Efficiency Grant (EEG) offers Irish businesses up to €30,000 to co-fund energy-efficient equipment, while homeowners can access significant SEAI supports to reach a B2 BER rating. Navigating these applications requires strict adherence to “apply before you buy” rules and registered contractor protocols to ensure your tax-free government support is secured.
As a Dublin-based Chartered Accountant, I see firsthand how rising utility costs squeeze the margins of our local SMEs—from the tech startups in the Silicon Docks to the family-run bistros in Rathmines. With the Carbon Tax increasing to €71 per tonne as of May 2026, energy efficiency is no longer just a “green” initiative; it is a core financial strategy for survival and growth.
The EEG is specifically designed for small and medium enterprises (SMEs) to reduce their operational carbon footprint.
The grant is managed through your Local Enterprise Office (LEO) and is divided into two distinct levels of ambition:
Base Tier: Supports pre-approved energy-efficient equipment with funding up to €30,000. This covers standard upgrades like LED lighting, commercial refrigeration, and high-efficiency heat pumps.
Advanced Tier: Reserved for larger, transformative investments that drive substantial energy savings across the entire business operation.
Pro Tip from OSA McQuillan: You must obtain a Green for Micro report or a SEAI Energy Audit before applying. The LEO will not approve retrospective applications—Switch to a proactive Dublin accountant today to ensure your paperwork is filed before you sign any equipment contracts.
For business owners who also own their homes or operate a home-based office, the SEAI offers a different path focused on the Building Energy Rating (BER).
To qualify for the National Home Energy Upgrade Scheme, your property must meet the following:
Current State: A BER of B3 or lower before works commence.
Target State: Must reach at least a B2 rating post-works.
Efficiency Gain: A minimum improvement of 100kWh/m² per year is required.
Compliance: You must use an SEAI-registered “One Stop Shop” to manage the project.

There is often confusion between long-term grants and temporary bill credits. As announced in previous budgets, domestic electricity customers received a total of €450 off their bills, paid in three installments of €150.
Key Update for 2026:
While these one-off credits provided temporary relief, Budget 2026 has shifted focus toward permanent structural changes, such as the 9% VAT rate on energy (now extended to 2030) and increased Fuel Allowances.
Action Step: Check your final 2025/early 2026 utility bills. If an installment is missing, contact your supplier immediately. For businesses, ensure these credits are correctly accounted for in your year-end tax returns to avoid overstating expenses.
To ensure you don’t lose out on thousands in funding, follow this strict 7-step protocol:
Identify Upgrades: Determine if you are targeting equipment (Business EEG) or building fabric (Residential SEAI).
Find a Registered Contractor: Use only SEAI-registered contractors. In Dublin, demand is high; Book a discovery call with us to discuss the tax implications of your contractor’s quotes.
The Energy Audit: Complete your Green for Micro or BER assessment.
Formal Application: Apply online via the LEO or SEAI portal. Do not start work yet.
Accept the Offer: You will receive a formal Letter of Offer. This is your “green light.”
Execute the Works: Ensure all invoices are VAT-compliant and match your grant approval.
Post-Works BER & Drawdown: Submit your post-works assessment and final costs to receive payment.
From an accounting perspective, receiving a grant isn’t “free money” without strings. Under the Enhanced Reporting Requirements (ERR), Irish employers must be diligent in how benefits are reported.
Capital Allowances: You can generally only claim capital allowances on the net cost of the equipment (Total Cost minus Grant).
VAT Recovery: Most VAT-registered SMEs can reclaim the VAT on the full invoice price, even if a portion of the net cost was covered by the EEG.
Don’t risk an audit. Switch to a proactive Dublin accountant who understands the intersection of SEAI grants and Revenue compliance.
If you are a sole trader operating from home, you generally fall under the residential SEAI schemes. However, if you have a separate commercial premises or a significant portion of your home is dedicated exclusively to business, LEO grants may apply. Book a discovery call for a specific assessment.
Typically, commercial refrigeration, LED lighting systems, high-efficiency motors, and variable speed drives. Domestic appliances for a staff canteen are usually excluded unless they are of a specific industrial energy-saving grade.
In Dublin, expect 4–8 weeks for LEO approval. Deep retrofits via the One Stop Shop can take several months from audit to completion.
The transition to a low-carbon economy is being heavily subsidized right now, but these funds are finite.
