What Factors Affect Business Gas Prices?
Unlike residential gas prices, commercial gas rates vary depending on market conditions, meter category, consumption and contract terms. The main factors that affect natural gas prices are:
- Wholesale market prices: Suppliers purchase natural gas in the wholesale market and add their operating costs and margin. Changes in wholesale prices affect the rates offered to businesses.
- Your gas meter category: Pricing structures differ depending on whether your business is classified as a Small Business User (SBU), Medium Business User (MBU) or Fuel Variation Tariff (FVT) customer.
- Contract length: Businesses can secure fixed prices for 12, 24 or sometimes 36 months. Longer contracts provide greater budget certainty and can be advantageous when wholesale gas prices are low.
Gas Meter Categories
Business gas tariffs are divided into different categories based on annual consumption and Supply Point Capacity (SPC).
- Small Business User (SBU): Businesses with annual gas consumption below 73,000 kWh.
- Medium Business User (MBU): Businesses with annual gas consumption between 73,000 kWh and 750,000 kWh. In addition, the SPC must be under 3,750 kWh.
- Fuel Variation Tariff (FVT): Larger gas users, generally consuming over 750,000 kWh annually, with pricing that includes additional capacity and transportation charges. The SPC must be over 3,750 kWh.

How to Compare Business Gas Prices (Step by Step)
Step 1: Check Your Current Gas Tariff and Charges
Before comparing gas prices, check your most recent business gas bill to identify:
- Your current meter category (SBU, MBU or FVT)
- Your Estimated Annual Consumption (EAC)
- Your Supply Point Capacity (SPC)
These details help suppliers calculate accurate quotes and determine which tariffs are available to your business.
Step 2: Avoid Rollover or Out-of-Contract Rates
If your commercial gas contract expires without a new agreement in place, your supplier will automatically move you onto expensive out-of-contract rates. These rates are usually twice as expensive as negotiated contract rates.
💡 Tip: Utilityfair monitors your gas contract expiry date and contacts you ahead of renewal, giving you time to compare suppliers and avoid expensive out-of-contract rates.
Step 3: Compare All Gas Suppliers
Compare prices from all Irish gas suppliers rather than simply accepting your existing supplier's renewal rates. A reputable, independent energy broker can make this process faster and easier. A good commercial energy broker will:
- Compare unit rates, standing charges, capacity charges and contract terms across all suppliers.
- Present a side-by-side comparison showing the estimated annual cost and potential savings.
- Explain the differences between fixed-price and wholesale tracker contracts.
- Recommend the best available option based on your business's gas consumption and requirements.
Check independent customer reviews on platforms such as Trustpilot before choosing a broker.

Step 4: Review Your Gas SPC and EAC
Your Supply Point Capacity (SPC) and Estimated Annual Consumption (EAC) affect your gas meter category and overall charges. If these figures are incorrect or set too high, you could be paying more than necessary, even with a competitive unit rate.
Reviewing your SPC and EAC before renewing your contract can help identify additional savings beyond the rates offered by suppliers.
Step 5: Choose the Right Gas Contract
The best contract will depend on current wholesale gas prices, your business requirements and how much price certainty you need.
- Short-term fixed contracts (6–12 months): Provide price certainty without committing to current rates for several years.
- Long-term fixed contracts (24–36 months): Offer greater budget certainty and can be particularly attractive when wholesale gas prices are low.
- Wholesale tracker contracts: Allow businesses to benefit when wholesale gas prices fall, but costs will increase if the market rises.

Common Mistakes Businesses Make When Comparing Gas Prices
- Allowing contracts to expire: Rolling onto expensive out-of-contract rates instead of securing a new agreement before the existing contract ends.
- Comparing unit rates alone: Overlooking standing charges, capacity charges and transportation costs that affect the total annual bill.
- Automatically renewing with the same supplier: Accepting renewal rates without comparing prices and contract options across the market.
