When it comes to choosing the right type of gas for your home, cost is often one of the most significant factors in decision-making. In many households, LPG (liquefied petroleum gas) and mains gas (natural gas) are two common options for heating and cooking. But how do they compare in terms of cost? Is LPG gas cheaper than mains gas? This article explores this question in detail, providing you with everything you need to know about the price differences between LPG and mains gas.
What Is LPG Gas?
LPG, or liquefied petroleum gas, is a mixture of hydrocarbons, primarily propane and butane. It is typically stored in pressurized containers or cylinders and is widely used for domestic heating, cooking, and even in certain vehicles. LPG is usually delivered by truck and is stored on-site at your property.
What Is Mains Gas?
Mains gas, also known as natural gas, is a fossil fuel primarily composed of methane. It is supplied to homes via a network of pipelines. Mains gas is one of the most common energy sources for heating and cooking in urban areas, and it is typically billed monthly or quarterly based on usage.
Comparing the Costs: LPG vs Mains Gas
To determine whether LPG gas is cheaper than mains gas, we need to consider several factors, such as energy content, installation costs, running costs, and availability.
Energy Content and Efficiency
One of the most important things to consider when comparing gas types is their energy content. Energy content is typically measured in kilowatt-hours (kWh).
LPG Gas: LPG has a higher energy content per unit of volume compared to mains gas. One kilogram of LPG produces about 13.9 kWh of energy. This means that LPG is a very efficient fuel for heating and cooking, but you may need less of it to produce the same amount of energy.
Mains Gas: Mains gas, primarily methane, has a lower energy content per unit of volume. One cubic meter of natural gas produces about 9.5 kWh of energy. However, due to the delivery method, mains gas is typically priced more affordably compared to LPG in most regions.
Price Comparison (Cost Per Unit)
The cost of LPG and mains gas depends on local pricing, delivery methods, and the quantity consumed. In general, mains gas is often cheaper than LPG on a per-kWh basis, but this can vary depending on your location.
LPG Gas Pricing: The price of LPG fluctuates based on several factors, including the supplier, delivery charges, and whether you are purchasing in bulk or using cylinders. As LPG is delivered in bulk or in containers, delivery fees can be substantial, especially if you live in a remote area. On average, LPG prices are higher than mains gas per kWh.
Mains Gas Pricing: Mains gas is delivered through a network of pipelines, meaning there are no significant delivery costs. The price of mains gas is typically regulated and can be relatively stable, making it a more affordable option for heating and cooking.
Installation and Setup Costs
While running costs are an important factor, the initial installation costs can also influence the overall expense of using LPG versus mains gas.
LPG Gas Setup: To use LPG, you’ll need a storage tank or cylinders, which can require an initial investment. If you’re installing an LPG tank on your property, you’ll also need to pay for the installation and any necessary plumbing or safety measures. This can be a significant upfront cost, especially if you need a large tank for heating purposes.
Mains Gas Setup: Mains gas typically requires less setup cost. If you’re already connected to the mains gas supply, you won’t have any installation fees unless you’re installing new appliances or need to extend the pipeline. However, if you’re not connected to mains gas, you may face significant costs for connecting to the gas grid, including trenching and laying down pipes.
Running Costs: Which is More Expensive?
Once the installation is done, the ongoing running costs will play a more prominent role in determining which option is more affordable.
LPG Gas Running Costs
The cost of running an LPG system depends on how much gas you use. Since LPG is typically more expensive per unit of energy, running your heating and cooking appliances on LPG may cost more than using mains gas. However, LPG tends to be more efficient, meaning you may need less of it for the same amount of heating. Still, when you factor in the price of delivery, the cost per unit can still be higher than mains gas.
Mains Gas Running Costs
Mains gas is often cheaper per kWh, making it a more economical choice in terms of ongoing running costs. The pipeline delivery system means there are fewer overheads involved, and the price of natural gas is generally lower than that of LPG. For households with access to mains gas, it is usually the cheaper option for heating and cooking.
Factors That Affect LPG and Mains Gas Prices
Several factors can influence the price of both LPG and mains gas, which can change over time.
Location
The location of your home plays a crucial role in gas prices. Mains gas is much cheaper in urban areas where it is readily available through pipelines. However, in rural or remote locations, where the gas grid does not extend, LPG is often the only option. In these areas, LPG prices can be much higher due to the cost of transportation and delivery.
Usage
The amount of gas you use will directly affect the cost comparison between LPG and mains gas. LPG users may face higher running costs for heating and cooking, but if you use gas sparingly, this might not be as significant an issue. On the other hand, mains gas is generally cheaper for those who have high gas consumption, such as for large homes with central heating.
Supply and Demand
Gas prices fluctuate based on supply and demand factors. For instance, during the winter months, heating demand typically rises, driving up the cost of both LPG and mains gas. Mains gas prices may also be affected by global natural gas prices, which can impact long-term cost trends.
Is LPG Gas Cheaper Than Mains Gas?
In summary, LPG gas is typically more expensive than mains gas, both in terms of cost per unit of energy and the overall setup and delivery fees. However, the price difference depends on several factors, including location, consumption levels, and the infrastructure available in your area.
For most urban households connected to the mains gas network, mains gas tends to be the cheaper and more practical option. However, in rural areas or where mains gas is not available, LPG may be the only viable option, despite its higher running costs.
Ultimately, the choice between LPG and mains gas will depend on your specific needs and circumstances. While mains gas is generally cheaper in the long run, LPG can offer advantages in certain situations, such as portability and higher energy efficiency.
Conclusion
When comparing LPG and mains gas, it’s clear that mains gas is often the more affordable option for the majority of households, especially in urban areas. However, LPG offers flexibility for those in rural areas or those who need gas but do not have access to the mains supply. By considering the energy needs of your household, installation costs, and the price of gas in your area, you can make a well-informed decision that best suits your financial and practical needs.
