Summer Energy Saving Tips

30-Second Overview

Managing energy costs has become a year-round priority for businesses. During summer, higher cooling demand, longer operating hours, and increased equipment use can push up electricity bills.

This guide provides practical, actionable tips to help businesses reduce energy usage during the warmer months, without affecting productivity or comfort. Simple adjustments to cooling, lighting, equipment, and staff routines can significantly cut commercial electricity and gas costs.

Start Planning Energy Efficiency Strategies Before Temperatures Rise

Preparing early helps prevent the spike in cooling and ventilation costs that often hits businesses during summer. Start by engaging your team on energy-saving goals and gathering their. A quick walkthrough of your premises can help identify:

Areas where heat builds up unnecessarily
Equipment producing excess heat
Opportunities to improve ventilation
Faulty cooling systems or worn seals on fridges or freezers
Ways to maximise natural light

It may also be worth scheduling a business energy audit. Identifying heat sources, inefficient equipment, or poor ventilation before the summer begins allows you to make cost-effective upgrades that keep your workspace comfortable.

Reduce Energy Usage by Optimising Cooling and Ventilation Controls

Cooling costs can rise significantly in warm weather. Before relying on air conditioning, focus on retaining cooler air indoors and preventing unnecessary heat buildup.

Close doors and windows during the hottest part of the day to keep warm air out.
Allow natural ventilation in the mornings and evenings when outside temperatures are lower.
Check thermostat settings to keep temperatures comfortable but efficient. Lowering air conditioning by 1°C typically adds approx. 3% to your cooling costs.
Use timers to ensure cooling systems aren’t running during unused periods.
Encourage appropriate summer workwear so the business doesn’t rely solely on air conditioning for comfort.
Keep blinds or curtains closed in direct sunlight, which reduces indoor heat gain.

Use Energy-Efficient Equipment and Lighting

Just like winter, inefficient equipment will result in unnecessary energy usage during summer. Small changes listed below add up, especially during long summer trading hours.

Routinely switch off appliances when not in use.
Use sockets and power strips with switches to easily turn off multiple devices.
Encourage staff to power down computers, printers, screens, and coffee machines at the end of the day.
When replacing appliances, choose high-efficiency models with reduce both energy use and excess heat.
Switch to LED lighting, which uses approximately 80% less energy and emits far less heat than traditional bulbs.
Make the most of longer natural daylight and ensure lights are off when unnecessary.
Install motion sensors or timers in low-traffic areas such as storerooms, toilets, or corridors.

How to Reduce Business Energy Consumption During Summer

Implementing the following measures can help your business significantly lower energy usage:

Efficient Water Usage: Heating water is expensive at any time of year. Fix leaks promptly, install low-flow taps, and run water-using appliances with full loads and at cooler temperatures. Consider investing in water-efficient appliances to reduce energy consumption.
Use Natural Ventilation: Reduce dependence on air conditioning open windows during cooler hours, prevent direct sunlight with blinds, and use fans where possible. Fans consume far less electricity than AC units.
Switch to LED Light Bulbs: LEDs produce minimal heat, last longer, and use a fraction of the energy of older bulbs.
Unplug Unused Devices: Chargers, screens, and small office appliances continue drawing power even when on standby mode and not in active use. Encouraging staf to switch off appliances when not in use.
Maintain Cooling Systems: Clean or replace air filters on AC units regularly and schedule maintenance checks before summer begins. Well-maintained systems run more efficiently and require less power.
Conduct an Energy Audit: Assess your business's energy usage and identify areas for improvement. An energy audit will help identify expensive problem areas, such as overheating zones, inefficient cooling, poor airflow, or outdated equipment—allowing for targeted improvements.
Educate and Involve Employees: Energy efficiency works best when everyone participates. Share simple guidelines, highlight waste, and encourage staff to take ownership of reducing unnecessary usage.
Switching Energy Suppliers: Reviewing your energy contract and exploring alternative suppliers can also lead to significant savings, especially if you haven’t checked rates in over 12 months.
