Before Winter: How Irish SMEs Can Turn Energy Uncertainty into a Tax-Efficient Investment Plan

Irish businesses cannot control international energy markets, but with the right technical and tax advice, they can take practical steps to reduce their exposure. 

“Few overheads are as uncertain, or as fundamental to the cost of doing business as the price of energy.”

That recent statement from William Walsh, CEO of the Sustainable Energy Authority of Ireland, captures the challenge facing Irish businesses as they prepare for autumn and winter.

Energy prices have always fluctuated, but Ireland’s dependence on imported energy leaves businesses particularly exposed to international events.

According to SEAI, Ireland imported 78.2% of its total energy requirement in 2025. Almost 93% of those imports were fossil fuels, including more than 82% of Ireland’s natural gas requirement.

This means international supply disruptions, geopolitical events and movements in global oil and gas markets can feed through to transport costs, heating bills and other business overheads.

For SMEs already managing pressure on wages, materials and finance costs, energy uncertainty is not simply an environmental issue. It is a cash-flow, competitiveness and business-planning issue.

Why businesses should act before winter 

The Commission for Regulation of Utilities has approved new electricity network arrangements applying from 1 October 2026 to 30 September 2027.

The approved revenue allowances for electricity distribution and transmission are respectively 18.4% and 8.1% higher than the 2026 allowances. The Public Service Obligation Levy will decrease, however, and the effect on an individual business will depend on its consumption, tariff and supplier contract.

Businesses should therefore be wary of treating any single market figure as a forecast of their future bill.

The more important point is that energy remains an uncertain and material overhead. Waiting until winter bills arrive may leave a business with fewer options and less time to assess potential investments properly.

The European Commission has also found that Europe’s increased reliance on globally traded liquefied natural gas has made European gas prices more exposed to international demand, shipping constraints and supply disruptions. This volatility can also affect electricity markets because gas-fired generation can influence wholesale electricity prices.

Irish SMEs cannot remove that international uncertainty. They can, however, reduce the amount of energy they consume and plan necessary investment more effectively.

Start with the business need—not the tax relief 

An energy-efficiency investment should make operational and commercial sense before its tax treatment is considered.

Depending on the business, potential measures might include:

• Heating, ventilation and air-conditioning systems
• Building-management and energy-control systems
• Refrigeration equipment
• Efficient motors, pumps and variable-speed drives
• Lighting and lighting controls
• Solar PV
• Heat pumps
• Electric vehicles and eligible charging equipment
• Other qualifying energy-efficient machinery

A professional energy consultant can assess how and where energy is being used, identify unnecessary consumption and compare potential measures based on expected savings, capital cost and payback period.

Eligible SMEs may also be able to obtain a €2,000 SEAI voucher towards the cost of a professional energy audit. In many cases, this can cover the full cost of the audit. Separate SEAI grants and technical-assistance supports may also be available for qualifying projects.

The technical recommendation is only one part of the investment decision. Before equipment is ordered, the business should also understand the available tax relief. The equipment must fall within one of the 10 classes detailed in the Accelerated Capital Allowances for Energy-Efficient Equipment [Section 285A TCA 1997]

How Accelerated Capital Allowances can help 

Under the standard capital-allowance rules, expenditure on most plant and machinery is generally deducted from taxable profits at 12.5% per year over eight years.

Accelerated Capital Allowances, or ACA, can allow a qualifying business to deduct 100% of the cost of eligible energy-efficient equipment from its taxable trading profits in the first year the asset is used.

The ACA scheme for energy-efficient equipment has been extended to 31 December 2030.

This does not make the equipment free, nor does it provide an additional deduction over and above the cost of the asset. Instead, it brings the available tax deduction forward, potentially improving the short-term cash-flow impact of a necessary investment.

The value of the relief will depend on matters including the business’s taxable profits, its applicable tax rate, the cost of the qualifying equipment and when the equipment is brought into use.

Rachel McKenna, Senior Tax Manager at Orbitus, explains:

“Businesses cannot control international energy prices, but they can control the timing, structure and tax treatment of investments made to reduce the upfront tax impact. It is worth seeking advice before equipment is ordered rather than waiting until after the relevant expenditure has already been incurred”.

Check eligibility before making a commitment 

Not every product described as energy-efficient will qualify for ACA.

Qualifying equipment must satisfy the relevant statutory conditions and SEAI energy-efficiency criteria. The product’s eligibility should be checked against the SEAI Triple E Products Register before the business commits to the purchase.

Businesses should also consider: 

• Whether the proposed product and equipment category qualify 

• Whether the equipment is new and unused 

• When the asset will be brought into use 

• Which business entity will acquire and use it 

• How any grant funding may affect the qualifying expenditure 

• What invoices, product details and supporting records should be retained 

• Whether ordinary capital allowances may be more appropriate in the circumstances 

Checking these points after an order has been placed may be too late to correct the structure or product selection. 

Bring the technical and tax conversations together

An energy consultant and a tax consultant perform different but complementary roles. The energy consultant can identify where energy is being wasted, recommend appropriate equipment and estimate the operational saving. The tax consultant can assess whether the proposed expenditure qualifies for accelerated relief, consider the timing of the investment and help ensure the correct documentation is retained.

Neither conversation should take place in isolation.

The strongest investment plan brings together:

1. The operational case for the upgrade 
2. The expected energy and cost savings 
3. Available grants and financial supports 
4. ACA and other relevant tax reliefs 
5. The effect on cash flow and project payback 
6. The timing of the purchase and installation

Prepare now—not after the bills arrive 

Energy-market uncertainty will remain outside the control of individual Irish businesses. Energy use, investment planning and tax treatment do not have to be.

Businesses considering upgrades during the remainder of 2026 should begin by establishing where energy is being consumed and which investments could produce a genuine commercial return.

Before committing to a significant equipment purchase, they should then obtain both professional technical advice and tax advice.
