Compare Live Business Gas Tariffs

Renewable business gas, often referred to as ‘green gas’, is growing in popularity as more businesses aim for higher levels of sustainability and a smaller carbon footprint. 

Green gas is sometimes called biomethane or biogas. It is produced by the breakdown of natural waste using organic bacteria in a process that is called anaerobic digestion. The process separates the carbon dioxide also produced, which leaves the green gas that is captured and then used to power UK homes and businesses instead of gas from fossil fuels. 

While green gas is sometimes available for businesses to switch to, depending on their circumstances, it can be a more expensive option. When a business chooses to switch to a green gas tariff, gas is provided to the premises in the same way as always, but the supplier will ensure that the equivalent amount of green gas is added to the grid.

If your business doesn’t sign a new contract with your current gas supplier or switch to another provider at the end of your existing term, you will usually be rolled onto a deemed contract for energy automatically. The business gas prices on this kind of tariff will usually be the highest that the provider charges, so it can be very costly not to take any action when your current contract is coming to an end. 

If you are coming to the end of your existing term, we can quickly compare business gas prices to help ensure you’re on the best possible deal available to your company.

Businesses with multiple sites or operating locations can also switch to another business gas deal. The way that comparing business gas prices for companies that have more than one place of operation will work depends on the circumstances. 

If all of the business locations have a current contract that ends on the same date, it may be possible to compare prices based on a multi-site contract, which can result in even more savings. 

If it’s the case that the different business premises for the same company have different end-dates to their current business gas contracts, we can compare deals for each site as and when it comes close to the end of the term. This approach can mean the business takes advantage of the best deal available at the time for each location, which may also bring significant savings for the company over time.

Business gas prices are heavily influenced by global market conditions, including:

• Supply and demand

• Geopolitical events

• Wholesale gas prices

The UK is particularly exposed to global gas markets, meaning price volatility can rapidly impact business energy costs.

Recent increases in gas prices have led to:

• Higher wholesale costs passed on by suppliers

• Fewer competitive fixed-rate deals

• Shorter availability windows for quotes

In volatile markets, prices can change quickly. Sometimes within days.

Your bill typically includes:

• Unit rate (cost per kWh)

• Standing charge (daily fee)

• Network and infrastructure costs

• VAT

Even if the unit rate looks competitive, total costs depend on all of these components.

There is no universal 'good' rate. Prices vary based on:

• Market conditions

• Contract length

• Usage levels

• Location

Instead of focusing on the unit rate alone, compare:

• Total annual cost

• Contract terms

• Flexibility

Gas prices fluctuate rapidly due to:

• Global supply disruptions

• Seasonal demand (e.g. winter heating demand)

• Energy market speculation

• Political and economic factors

Because the UK relies heavily on gas, businesses are directly affected by these changes.

Yes. In volatile markets:

• Suppliers may withdraw tariffs quickly

• Quotes may only be valid for a short time

This means timing can play a significant role when securing a contract.

It depends on your risk tolerance.

• Fixed contracts:
  Provide price certainty, but may lock you into higher rates

• Variable contracts:
  Offer flexibility, but expose you to price increases

Many businesses choose fixed deals for stability, especially during volatile periods.

To secure the best deal:

• Compare multiple suppliers

• Review contracts before renewal deadlines

• Consider using a broker or comparison service

• Monitor market conditions

• Avoid default rollover tariffs

Timing and preparation play a key role in securing competitive pricing.

Many businesses receive unsolicited energy sales calls.

While some may be legitimate:

• Offers can lack transparency

• Prices may not always be competitive

Most businesses prefer to:

• Research independently

• Request quotes directly or through trusted intermediaries

Higher gas prices can impact:

• Operating costs

• Profit margins

• Pricing of goods and services

• Heating and production expenses

For some businesses (e.g. hospitality or manufacturing), gas is a major cost driver.

In the UK, gas is a major source of electricity generation.

Because of this:

• Gas often sets the market price for electricity

• Rising gas costs can increase electricity prices as well

This means businesses may see rising costs across both utilities.

Businesses can reduce gas costs by:

• Switching to more competitive contracts

• Improving energy efficiency

• Reducing heating demand

• Upgrading insulation or equipment

• Using alternative energy sources where possible

Business gas contracts can be complex due to:

• Different pricing structures

• Varying contract lengths

• Additional charges

This makes direct comparison more difficult than domestic energy tariffs.

Contracts are often more detailed because they are tailored to business usage.

However, this can make:

• Pricing harder to understand

• Comparisons less transparent

Carefully reviewing terms and asking for full cost breakdowns is essential.

You may be overpaying if:

• You haven’t reviewed your contract in several years

• You are on a rollover or default tariff

• Your usage patterns have changed

Regularly comparing suppliers and reviewing contracts can help ensure you stay competitive.
