30-Second Overview
Getting the best natural gas price for business requires more than just comparing unit rates. Key factors like your Estimated Annual Consumption (EAC) and Supply Point Capacity (SPC) also affect what you pay. Whether you’re categorised as a Small Business User (SBU), Medium Business User (MBU), or Fuel Variation Tariff (FVT), the best deal will depend on:
- Choosing the right supplier and contract length;
- Setting your SPC and EAC correctly;
- Avoiding out-of-contract or default rates;
- Using a broker like Utilityfair to quickly compare offers from all major gas suppliers.

What Factors Affect Natural Gas Contract Prices?
Unlike residential energy rates, commercial gas pricing is bespoke. Supplier price plans vary based on market conditions, your meter category and usage profile.
The main factors that affect natural gas price plans are:
- Wholesale market prices: Your supplier must purchase gas in the wholesale market before selling it to you, with their margin added on top.
- Your gas meter category: Suppliers have different pricing structures depending on which meter category you fall into - Small Business User (SBU), Medium Business User (MBU), or Fuel Variation Tariff (FVT).
- Contract length: Businesses can lock in pricing for 12 months, 24 months and sometimes 36 months. Your supplier purchases natural gas futures in the wholesale market to cover your contract. If natural gas prices are low, a longer contract may be beneficial and will give you a greater degree of budget certainty over a multi-year horizon.
Gas Meter Categories
- Small Business User (SBU): This is the default tariff for small businesses with annual usage under 73,000 kWh.
- Medium Business User (MBU): The annual usage must be between 73,000 kWh and 750,000 kWh. In addition, the SPC must be under 3,750 kWh.
- Fuel Variation Tarriff (FVT): The annual usage must be greather than 750,000 kWh. In addition the SPC must be over 3,750 kWh.

How to Get the Best Natural Gas Deal (Step-by-Step)
Step 1: Understand Your Current Meter Category and Charges
Check your most recent gas bill and identify:
- Your current tariff structure (SBU, MBU, FVT);
- Your Estimated Annual Consumption (EAC);
- And, your Supply Point Capacity (SPC).
Step 2: Avoid Rollover or Out-of-Contract Rates
If your contract ends and you haven’t switched suppliers or negotiated a new contract, your supplier will move you to out-of-contract rates. These rates are up to 40% more expensive than negotiated rates.
💡 Tip: Utilityfair tracks your commercial gas contract end dates, so you never get caught out paying expensive out-of-contract rates.
Step 3: Compare Multiple Suppliers
Use a reputable broker like Utilityfair. Make sure to check independent customer reviews so that you know you have someone that you can trust. Just like other online products, reputable brokers use independent review platforms like Trustpilot, which makes it easy for you to check.
A good commercial energy broker can:
- Compare unit rates, standing charges, and contract terms from all suppliers and present you with the results and cost savings.
- Access exclusive rates from all Irish gas suppliers.
- Advise you on the differences between contract options and suppliers so that you can pick the best option for your business requirements.

Step 4: Review Your Gas SPC and EAC
Your SPC and EAC affect your meter pricing category and capacity-related charges. If these are not set correctly, you could be overpaying even with a good unit rate.
Step 5: Negotiate the Right Contract Term
The best contract term will vary depending on market conditions and wholesale gas prices. Our experts guide you through the best term for your business’s needs.
- A fixed 6-month or 12-month contract offers stability during volatile periods.
- A 24-month or 36-month contract is advantageous when wholesale gas prices are lower, and gives you budget certainty for a longer period of time
Common Mistakes Businesses Make When Comparing Gas Prices
❌ Letting contracts auto-renew on high rates
❌ Comparing unit rates only, and ignoring capacity, additional transportation charges, and standing charges
❌ Staying with the same supplier out of habit and not checking other supplier pricing annually

To find the best business gas prices in Ireland, compare quotes from multiple suppliers, review your current tariff, and check your SPC and EAC. A reputable broker like Utilityfair can help you secure the most competitive commercial gas deal.
The cheapest tariff depends on your annual consumption and SPC.
