How Can Businesses Reduce Gas Costs?
There are some simple steps businesses can take that will help reduce gas bills and energy usage. The main areas where gas costs can be cut quickly without capital expenditure are:
Switch Your Natural Gas Supplier
Switching suppliers can cut gas costs by up to 35–55%. Even negotiating with your current supplier and avoiding expensive out-of-contract rates can result in significant savings.
💡 Pro-Tip: Switching energy providers is one of the easiest ways to cut energy bills. Utilityfair can quickly estimate your annual savings by switching price plans or suppliers.
Use Energy-Efficient Equipment
Choose gas-powered appliances with high-efficiency ratings, and power them off when not in use. Even small efficiency gains accumulate savings over time.
Lower the Thermostat
Reducing your thermostat by just 1°C can shrink heating costs by approximately 10%. You don’t need a warm business when you’re not at work, as that will just increase heat loss:
- Time heating so that your business is warm during working hours, and let it cool down in between.
- Using a programmable thermostat makes it easy to regulate the temperature.
- If you can, it could be worth keeping the thermostat in a place with limited access so that temperature settings are regulated by just a few people in the business.
- However, be careful not to turn off your heating entirely, as this may cause pipes to freeze during the cold winter months. In addition, the cost of reheating your business from a very cold starting temperature may outweigh the benefits.
Seal Draughts and Improve Insulation
Draught-proof windows and doors, and consider long-term insulation investments, such as insulating walls, ceilings, or heated areas. Though upfront costs apply, benefits in comfort and savings are substantial over time.
Reduce Hot Water Waste
Fix leaky taps and limit hot water use to essential operations. Heating water via gas can be a significant cost factor.
Engage Your Employees
Educate staff on energy-saving habits and appoint an Energy Champion to drive awareness and consistent savings behaviour.
Encourage Warm Clothing
Allow warm clothing during colder months to reduce unnecessary heating and maintain comfort.
Keep Exterior Doors Closed
Ensure external doors remain closed to prevent heat loss. This is especially important for retail or facilities entrances. Revolving doors offer an efficient long-term solution.
Don’t Block Heaters or Vents
Ensure all vents and heaters have free airflow. Blocking them reduces heating efficiency and increases energy consumption.
Conduct an Energy Audit
An energy audit, whether DIY or professional, helps identify where you're losing heat or gas efficiency, allowing you to focus efforts on high-impact improvements.
Avoid Out-of-Contract or Rollover Rates
Don't risk being put on expensive variable rates at the end of your contract. These can cost 30–40% more than a renegotiated deal. Early renewal and supplier price comparisons are critical.

Frequently Asked Questions (FAQs)
Switching to a new business gas supplier can cut your bills by up to 55% compared to out-of-contract or rollover rates. New contracts often include competitive unit rates, fixed-term stability, and tailored tariffs that suit your business’s usage patterns. Regularly comparing suppliers ensures you’re not paying more than necessary.
Small daily actions add up to big savings, such as lower your thermostat by 1 °C; turning off gas-powered appliances when not in use; and keeping doors closed and vents unblocked. These steps can reduce gas bills by 10–15% with no major investment.
When staff are aware of the impact of energy waste, they’re more likely to support cost-saving actions. Simple behaviours — like closing doors, reporting draughts, or using appliances efficiently — can collectively deliver measurable reductions in usage.
You should review your gas contract at least three months before it ends. This allows time to compare the market, avoid rollover rates, and negotiate better terms. Energy markets fluctuate, so an annual review ensures you’re always on the most competitive plan.
Out-of-contract (or rollover) rates are applied automatically if you don’t actively renew or switch. They’re typically 30–40% higher than negotiated rates, which are agreed in advance with a supplier and tailored to your business’s consumption profile.
Yes. An energy audit pinpoints inefficiencies, identifies equipment that could be upgraded, and suggests behavioural or operational changes that deliver the highest return on investment. Many audits reveal savings opportunities of 10–25%.
If you operate in an older or poorly insulated building, insulation upgrades can be one of the most cost-effective long-term solutions. They reduce heating needs, improve comfort, and protect against future gas price rises.
Fixed contracts provide price stability and protect against sudden market spikes. Monthly (variable) contracts can be cheaper if wholesale prices are falling, but they carry more risk. The right choice depends on your risk tolerance and market conditions.
Contact your current supplier immediately to negotiate a new contract, and compare rates from other suppliers. In many cases, switching can be arranged within a few weeks, helping you avoid months of inflated charges
Yes, actions like lowering the thermostat, shutting doors, and fixing leaks cost nothing but can reduce bills by hundreds of euros annually for larger sites. When combined with strategic investments, these changes form the foundation of effective gas cost management.
