Business Electricity Comparison vs Gas: Which Is Cheaper?
When comparing business electricity and gas, it is important to look at more than just the price on your bill. Many small businesses think gas is always cheaper. While this is often true, it is not always the best choice for every business.
Electricity and gas are used for different things. Gas is mostly used for heating, cooking, and large systems. Electricity powers lights, machines, computers, and more. Because of this, your business type plays a big role in which is cheaper.
In the UK, gas usually has a lower unit rate than electricity. This means you pay less per kilowatt-hour (kWh). However, electricity can be more efficient. Some electric systems waste less energy, which can balance out the higher price.
Let’s break it down simply:
| Energy Type | Average Cost | Best Use | Key Benefit |
| Gas | Lower per kWh | Heating, cooking | Cheaper for bulk use |
| Electricity | Higher per kWh | Equipment, lighting | Cleaner and flexible |
So, which is cheaper? The answer depends on how your business uses energy every day.
You can also explore which energy is best for your business to make a smarter choice.
Understanding Cost Per Unit
Gas is often cheaper than electricity when you compare unit prices. For example, gas may cost around 7p per kWh, while electricity can cost 25p or more per kWh.
This means if you use a lot of energy for heating, gas is usually the better option. Restaurants, factories, and large offices often benefit from gas systems.
However, electricity is not always expensive in real terms. Electric systems can be more efficient. For example, electric heaters can turn almost all energy into heat, while gas systems may lose some energy.
So, even though electricity costs more per unit, it may not always cost more overall.
How Your Business Type Affects Cost
Different businesses use energy in different ways. This is key when comparing gas and electricity.
- Offices mostly use electricity for computers and lighting
- Restaurants use both gas (cooking) and electricity (equipment)
- Shops rely heavily on electricity
- Warehouses may use gas for heating large spaces
If your business uses a lot of heating, gas will likely be cheaper. If your business uses machines and tech, electricity will be your main cost.
A smart approach is to match the energy type to your needs.
Standing Charges and Hidden Costs
Energy bills are not just about unit rates. You also pay standing charges. These are daily fees for being connected to the energy network.
Electricity often has higher standing charges than gas. This means even if you use less electricity, you may still pay more overall.
Other costs to consider include:
- Installation costs
- Maintenance costs
- Contract exit fees
- Meter upgrades
For example, switching from gas to electric heating may require new systems. This can be expensive upfront.
Efficiency and Energy Waste
Efficiency is often ignored, but it matters a lot.
Gas systems can lose heat through pipes and vents. Electric systems are often more direct. This means less waste.
Here is a simple comparison:
- Gas boilers: around 70–90% efficient
- Electric heaters: close to 100% efficient
So even if gas is cheaper per unit, you may need more of it to get the same result.
Environmental Impact and Future Costs
Electricity is becoming greener in the UK. More energy now comes from renewable sources like wind and solar.
Gas is a fossil fuel. Over time, it may become more expensive due to carbon taxes and regulations.
Many businesses are now choosing electricity to reduce their carbon footprint. This can also improve brand image and attract eco-friendly customers.
In the future, electricity may become the smarter long-term choice.
Example
Imagine two small businesses:
- A café using gas for cooking and heating
- A tech office using only electricity
The café saves money with gas because it uses a lot of heat. The office has no need for gas and relies on electricity.
This shows there is no one-size-fits-all answer.
Is Gas Always Cheaper Than Electricity?
Gas is often cheaper per unit, but not always cheaper overall. If your system is inefficient or poorly maintained, you may lose money.
Electric systems can be cheaper in small spaces or for low usage. Also, if you use energy-saving devices, electricity costs can drop.
A good tip is to compare total monthly costs, not just unit rates.
When Should a Business Choose Electricity Over Gas?
Electricity is a better choice when:
- Your business uses more equipment than heating
- You want a cleaner energy source
- You need flexible and easy installation
- Your space is small or modern
Electric systems are also easier to control. Smart meters and timers help reduce waste.
Many new buildings are now designed for electric use only.
How to Save Money on Business Energy
Saving money is not just about choosing gas or electricity. It is about using energy wisely.
Here are simple tips:
- Switch suppliers regularly
- Compare fixed and variable rates
- Use energy-efficient appliances
- Turn off unused equipment
- Insulate your building
