Cut Your Cork Business’s Electricity Costs
Haven Electrical carry out commercial energy efficiency audits and implement electrical upgrades for businesses across Cork City and County. We start with a proper site assessment — measuring actual consumption by circuit, identifying high-energy equipment, and assessing lighting, motor, and HVAC loads. From that baseline, we produce a prioritised upgrade plan with payback periods and projected savings for each measure. Common upgrades include LED lighting retrofits, power factor correction, sub-metering systems, and time-of-use controls. We carry out all upgrade work ourselves, so there’s no disconnect between the audit findings and the installation quality.
Measurement-Based Audits
We measure actual energy consumption by circuit and area — not just a visual inspection. Real data drives the recommendations.
Prioritised Upgrade Plans
Audit findings presented as a prioritised upgrade schedule with projected savings and payback periods for each measure.
RECI Certified Upgrades
All electrical upgrade works carried out by RECI-registered electricians and certified on completion.
Free Initial Survey
Free initial site survey for all commercial energy efficiency audits across Cork City and County.
// What You Get //
What’s Included in a Commercial Energy Audit
Site energy consumption survey
Measurement of consumption at main distribution board and sub-boards to identify the largest loads.
Lighting assessment and LED upgrade plan
Lighting load survey, lux level assessment, and LED retrofit specification with savings projection.
Motor and drive efficiency assessment
Assessment of motor loads and recommendation for variable speed drives where appropriate.
Power factor measurement
Power factor measured at incoming supply — poor power factor wastes energy and can attract charges from your supplier.
Sub-metering and monitoring setup
Sub-meters installed at key distribution points for ongoing consumption monitoring.
Time-of-use controls and scheduling
Timer controls, occupancy sensors, and daylight sensors identified and installed where appropriate.
LED lighting retrofit
Full LED retrofit of fluorescent, halide, or incandescent fittings across the premises.
Power factor correction equipment
Power factor correction capacitor banks specified and installed where measurement identifies poor PF.
Audit report with savings projections
Written report with baseline consumption data, upgrade recommendations, and projected annual savings per measure.

We audit and carry out the upgrade works ourselves. No separate contractors to coordinate — the people who found the problem fix it.
Real Savings, Real Numbers
Our energy audits are based on actual measurements. The savings projections in our reports are based on real consumption data, not industry averages.
Fast Payback on LED
LED lighting retrofits typically achieve payback within 1–3 years for commercial premises with high operating hours. Many Cork businesses see 50–70% reductions in lighting electricity costs.
RECI Certified Works
All electrical upgrade works are carried out to RECI standard and certified on completion.

Energy Efficiency FAQs
A commercial energy audit is a structured assessment of how your premises uses electricity, identifying where energy is being consumed and where it’s being wasted. A proper audit involves measuring actual consumption at distribution board level, assessing the efficiency of lighting, motors, heating and cooling systems, and identifying control and behavioural changes that can reduce consumption. We follow the measurement with a prioritised upgrade plan showing the cost of each measure and the projected annual savings.
Power factor is a measure of how efficiently your electrical system uses the power it draws from the grid. A poor power factor (below about 0.9) means your equipment is drawing reactive current that you’re paying for without getting useful work from it. Some electricity suppliers charge larger commercial customers for poor power factor. Power factor correction capacitor banks correct this, typically paying back their cost within 1–3 years. We measure your power factor as part of a full energy audit.
A well-designed LED lighting upgrade typically reduces lighting electricity consumption by 50–70% compared with fluorescent or HID lighting. For a warehouse or factory in Cork with high lighting loads and long operating hours, this can mean savings of €5,000–€20,000 per year or more. For a small office, savings might be €500–€2,000 per year. We carry out a lighting audit before specifying any LED retrofit, so our savings projections are based on your actual situation.
Yes — SEAI (the Sustainable Energy Authority of Ireland) offers grants for commercial energy efficiency upgrades including LED lighting, controls, and energy management systems. The schemes available and eligible measures change regularly. We advise customers to check the current SEAI commercial grant offerings before committing to an upgrade project. We can help you understand what evidence and documentation you’ll need from the installation.
Sub-metering installs energy meters at key distribution points — for example, at individual production lines, buildings within a campus, or large loads like HVAC systems. It gives you visibility of where your energy is going in detail, rather than just knowing the total monthly bill. Sub-metering is particularly valuable for larger premises, multi-tenant buildings, and businesses with variable production. It makes energy reduction efforts targeted and measurable.
A basic visual and measurement audit for a small–medium commercial premises typically takes half a day to a full day on site. The written report and upgrade plan is typically delivered within a week. For larger or more complex sites, a more detailed audit may take longer. We discuss the scope and timeline before starting.
Yes — industrial LED lighting retrofits for warehouses, factories, and distribution centres are one of the most common energy upgrade projects we carry out across Cork. High-bay LED fittings replace metal halide or T5 fluorescent installations, typically cutting lighting energy consumption by 50–70% and significantly improving light quality. We carry out all electrical works including new wiring, new fittings, and controls.
We plan all upgrade works to minimise operational disruption. LED retrofit programmes can typically be phased across weekends or evenings. Power factor correction work can usually be carried out with brief planned outages. Sub-meter installation is usually non-disruptive. We’ll agree a delivery plan with you before starting any upgrade works.
