Introduction
Gas is an essential utility for thousands of UK businesses. From manufacturing plants and commercial kitchens to office heating and hospitality, business gas plays a crucial role in day-to-day operations. However, with business gas prices rising due to global energy demand, inflation, and supply disruptions, securing the best deal has never been more important.
Whether you’re a small business owner looking to reduce overheads or a procurement manager managing multiple sites, understanding the gas market and your contract options can lead to significant savings. In this guide, we’ll break down how commercial gas pricing works, who offers the most competitive rates, and what steps you can take to lock in the best business gas prices today.
What Are Business Gas Prices?
Business gas prices refer to the rates that companies pay for natural gas consumption. These prices are different from domestic tariffs and are not subject to government price caps. Instead, business rates are calculated based on:
- Your annual usage (measured in kWh)
- Contract length
- Business size and sector
- Credit rating
- Type of meter installed
- Location in the UK
- Wholesale gas market trends
Because business gas prices fluctuate frequently, suppliers usually provide custom quotes rather than fixed public tariffs.
How Business Gas Pricing Works
Understanding how suppliers calculate business gas tariffs is key to making smart decisions. A commercial gas bill typically consists of:
1. Unit Rate (p/kWh)
This is the price you pay for each kilowatt-hour of gas you consume.
2. Standing Charge (daily)
A fixed fee that covers the cost of supplying gas to your premises, including infrastructure and maintenance.
3. Climate Change Levy (CCL)
A government-imposed tax on non-renewable energy usage for businesses. Exemptions apply to some sectors and green contracts.
4. VAT
Business gas is usually charged at 20% VAT unless you qualify for the reduced 5% rate (e.g., charities or low-usage businesses).
Tip: Always calculate the total annual cost, not just the unit rate, to compare offers accurately.
Fixed vs Variable Business Gas Contracts
When choosing a supplier, you’ll generally choose between a fixed or variable tariff.
Fixed Tariff
- Locks in your unit rate for 1–5 years
- Protects you from market volatility
- Easier to budget and forecast
Variable Tariff
- Price changes with the wholesale gas market
- May save money if prices fall
- Higher risk if prices spike unexpectedly
Most businesses opt for fixed tariffs to gain pricing stability and avoid uncertainty.
How to Compare Business Gas Prices
To find the best deal for your business, follow this step-by-step approach:
- Gather your usage data: Look at your last 12-month consumption in kWh
- Know your renewal date: You can compare quotes up to 12 months in advance
- Use a comparison tool: Get tailored quotes at Switch-Us.net
- Compare total costs: Include unit rate, standing charge, and contract fees
- Check contract terms: Look for early exit fees, auto-renewals, and hidden charges
- Choose the right contract length: Match your business plans with the appropriate duration
Don’t just rely on a single quote—prices can vary by 30–40% between suppliers for the same business profile.

What Affects Business Gas Prices?
Several factors influence how much you’ll pay for gas as a business, including:
1. Global Wholesale Prices
Changes in international supply and demand—such as conflict, supply chain issues, or weather—affect the cost of gas worldwide.
2. Seasonal Demand
Colder months increase usage and prices, especially in Q4 and Q1. Lock in prices during the summer for better deals.
3. Contract Length
Longer contracts often secure better unit rates but may carry more risk if you want to switch early.
4. Credit Rating
Suppliers assess your creditworthiness when quoting. Poor credit may lead to higher rates or security deposits.
5. Consumption Profile
High and consistent usage may qualify you for volume discounts or tailored pricing models.
Multi-Site Gas Contracts
If your business operates from multiple premises, consolidating your energy needs under a multi-site gas contract can unlock cost efficiencies:
Benefits:

- Central account management
- Bulk usage discounts
- Simplified contract renewals
Suppliers like Opus Energy, SmartestEnergy, and TotalEnergies specialise in this type of account structure.
Green Business Gas Options
Although natural gas is a fossil fuel, many providers now offer green gas alternatives such as:
- Biomethane (gas produced from organic matter)
- Carbon offsetting (investment in CO₂-reducing projects)
Why choose green gas?
- Aligns with sustainability targets
- Enhances brand reputation
- May reduce future compliance costs
- Eligible for some green business incentives
Suppliers like Octopus Energy, Good Energy, and Ecotricity lead the market in green gas offerings.
Smart Metering and Energy Efficiency
Installing a smart gas meter offers real-time visibility into your consumption, allowing you to:
- Detect leaks or spikes
- Track seasonal trends
- Adjust thermostat or process usage
- Receive accurate bills (no more estimates)
Most suppliers now install smart meters free of charge with new contracts.
Contract Length: How to Choose
| Contract Length | Best For | Pros | Cons |
|---|---|---|---|
| 12 months | Short-term rentals, unstable usage | Flexibility | Slightly higher rates |
| 24–36 months | Most SMEs | Balanced cost and commitment | Locked pricing |
| 48–60 months | Stable, high-usage firms | Best unit rates | Long-term risk |
Hidden Charges to Watch Out For
When comparing business gas prices, don’t overlook hidden costs:
- Out-of-contract rates: Charged if you miss your renewal deadline
- Broker commission: May be included in unit rate
- Meter reading fees: For older, non-smart meters
- Termination penalties: Charged for switching early
Always read the terms and ask for a full breakdown before committing.
Switching Business Gas Suppliers: Step-by-Step
- Review your current contract – check end dates and exit clauses.
- Get usage data – last 12 months in kWh.
- Compare quotes on Switch-Us.net – get customised offers.
- Choose your tariff and contract length – fixed is most popular.
- Sign your new contract – digitally or through a broker.

You can schedule the switch to happen the day your current deal ends—avoiding out-of-contract pricing.
FAQs About Business Gas Prices
Q: Are business gas prices higher than domestic ones?
Yes. Businesses don’t benefit from the same consumer price caps and typically use more energy, so rates are structured differently.
Q: Can I switch gas suppliers mid-contract?
Only if your contract allows it. Otherwise, you may face early termination fees.
Q: How can I lower my business gas bill without switching?
- Install a smart thermostat
- Schedule equipment usage during off-peak times
- Maintain equipment to prevent waste
- Insulate buildings properly
Q: Is green gas more expensive?
Often slightly, but the long-term reputational and regulatory benefits outweigh the extra cost for many businesses.
