What affects business gas prices?
Several factors influence the cost of a business gas supply, often causing fluctuations from month to month or year to year. Understanding these can help you make better decisions when arranging your gas tariffs.
Wholesale price of gas
Business gas suppliers purchase natural gas from producers and European and LNG importers. The most important determinant of gas quotes is the prices that suppliers can secure when purchasing gas to supply your business.
Length of contract
Business gas quotes are typically fixed for between one and three years. Suppliers usually offer a discount for longer contracts to reward loyalty; however, this also depends on the market’s expectations of future gas prices.
Your gas network
Regional gas distribution networks and independent gas transporters charge distribution fees that vary based on the location of your commercial property.
Market competition
Gas suppliers incorporate a profit margin into their business gas quotes. When a supplier is seeking to grow their business, they may offer more competitive quotes at a lower profit margin to attract new customers.
Green gas supplies
Some business gas suppliers offer green commitments, such as sourcing a percentage of your gas from biogas or purchasing green gas certificates. Green commitments typically raise the price of business gas quotes.
Gas connection
The capacity of your business gas connection, recorded within your MPRN, determines the fixed charges for maintaining the connection to the local gas grid.
Global gas supply and demand
Supply shortages, increased global demand, or geopolitical events can impact the cost of gas. The UK relies on imported gas through the Langeled pipeline, making it vulnerable to these global market changes.
Seasonal demand
Business gas prices often rise during colder months as demand increases for heating. Conversely, prices may fall during warmer months when demand is lower.
How to calculate business gas prices per kWh
Although business gas rates are billed per kWh, what really matters to your business is the total amount you’ll pay each month. You can estimate this easily using three figures from your latest bill.
Step 1. Gather your key figures
You’ll need:
- Your unit rate (pence per kWh)
- Your standing charge (pence per day)
- Your monthly gas usage (kWh)
Step 2. Calculate your total monthly cost
Multiply your usage by the unit rate to find your total energy cost, then add the standing charge for the number of days in the month.
Total monthly cost = (unit rate × kWh used) + (standing charge × days in month)
Example calculation
A small business using 2,000 kWh of gas in a 30-day month with a 7.2p unit rate and a 35p daily standing charge would pay:
- Energy consumption cost = 2,000 × £0.072 = £144.00
- Standing charge = 30 × £0.35 = £10.50
- Total monthly gas cost = £154.50 (excluding VAT and CCL)
Types of business gas tariffs
Choosing the right business gas tariff depends on whether your business values price cost certainty, flexibility, or lower emissions. Most suppliers offer three main tariff types: fixed, variable, and green.
Fixed-rate tariffs
A fixed-rate business gas tariff locks in your unit price for the full contract term, typically one to three years. It provides predictable bills and shields your business from market price spikes, making it ideal if you prioritise cost stability and accurate budgeting.
Variable-rate tariffs
Variable tariffs track movements in the wholesale gas market. When prices fall, you can benefit from cheaper rates, but when the market rises, your costs increase. This option suits businesses that are comfortable with some risk in exchange for potential savings.
Green gas tariffs
Green gas tariffs supply energy sourced from renewable biogas or offset traditional gas through carbon credits. These contracts help businesses lower their carbon footprint and align with wider green business energy goals.
Flexible tariffs
Flexible energy contracts allow businesses to purchase gas in portions over time rather than locking into a single rate at contract start. You can buy gas from the market at different points, which means you can take advantage of price dips. This option works best for larger businesses with the time and resources to actively manage their energy purchasing.
Pass-through tariffs
Pass-through tariffs separate the wholesale gas energy cost from the non-commodity charges, such as network and distribution costs, which are billed at their actual rate rather than bundled into a fixed unit price. This gives businesses greater transparency over what they are paying for.
Business gas prices FAQs
Below, we answer the most commonly asked questions about business gas prices.
How much does business gas cost per kWh?
The cost of business gas per kWh depends on several factors, including your supplier, location, tariff type, contract length, and the current state of the wholesale gas market.
Prices fluctuate in line with wholesale market conditions, which means the rate your business pays can vary significantly depending on when you sign a contract. As a general guide, small businesses typically pay between 7p and 12p per kWh, though rates outside this range are possible during periods of market volatility.

What’s included in business gas rates?
Business gas rates are the charges companies pay to use natural gas from the gas mains network.
These rates are outlined in your gas tariff and used to calculate your monthly business gas bill.
Here’s a summary of the different types of business gas rates:
- Unit Price: A charge for each unit (kWh) of gas consumed, measured automatically by a smart meter or manual gas meter readings. Unit rates can be fixed or variable.
- Business Gas Standing Charges: A fixed daily cost, calculated in pence per day, covers the maintenance of your connection to the local gas distribution network.
- Climate Change Levy (CCL): A government tax encouraging efficient gas usage, charged at 0.801 pence per kWh. Learn more in our guide to CCL for businesses.
- Value-Added Tax (VAT): Business gas rates are subject to VAT under UK law. Microbusiness energy customers pay 5% VAT, while all other businesses pay the standard rate of 20%. Learn more in our VAT on business energy bills guide.
What other business gas costs should I consider?
While your gas tariff will detail the main charges, such as the unit price, standing charges, the Climate Change Levy, and VAT, there are additional costs you should be aware of when reviewing your overall gas costs.
For example, you might encounter one-off connection or installation fees if you’re setting up a new gas supply. Some contracts include meter operator fees for installing or maintaining your gas meter, especially if it’s an older advanced business gas meter.
You may also face administrative or service fees for account management and charges for early contract termination or changes to your agreement. In variable tariffs, look out for market adjustment fees that reflect fluctuations in wholesale costs or regulatory changes.
Awareness of these extra costs can help you compare offers more accurately and choose the best deal for your business.
What is a good business gas rate?
A good business gas rate aligns with current market conditions and offers competitive pricing compared to other suppliers. It takes into account:
- The state of the wholesale gas market: Prices fluctuate based on supply and demand dynamics.
- Geopolitical influences: Events like the Ukrainian conflict can significantly impact prices.
- Contract terms: Customers can be rewarded with lower rates for agreeing to longer tariffs.
In Britain, there are over 30 business gas suppliers competing to offer the best prices. At Business Energy Deals, we specialise in connecting small businesses with the best business gas rates.
Why are some business gas prices cheaper than others?
Business gas prices are not uniform. Two businesses on the same street can be paying very different rates, and understanding why can help you secure a better deal.
The main factors that influence what your business pays:
- Annual consumption: Businesses with a higher expected annual consumption typically access lower unit rates, as suppliers offer better pricing for larger volumes of gas.
- Contract length: Suppliers typically offer cheaper unit rates on longer contracts, as they benefit from a guaranteed customer over a fixed period. Shorter contracts may carry a premium to reflect the reduced commitment.
- Location: Distribution and transportation costs vary across Britain, meaning your region can affect your unit rate.
- Tariff type: Businesses on fixed contracts are protected from market movements and typically pay the cheapest rates, while those on variable or out-of-contract rates are exposed to price changes and typically pay significantly more.
