Is gas cheaper than electricity in the UK right now?
Yes, gas is still cheaper than electricity in the UK in 2026 when you compare the cost per kWh. Electricity prices remain significantly higher, mainly due to generation costs, network charges, and environmental levies, while gas is still widely used for heating and benefits from lower unit pricing.
However, the gap is not as simple as it looks. Electricity is more efficient (especially with heat pumps), while gas boilers lose more energy during combustion. So, the "cheapest" option depends on how energy is used, not just the unit price.
Average gas vs electricity prices per kWh (UK – 2026)
Energy Type | Average Price per kWh | Typical Use |
Gas | £0.06 – £0.08 | Heating, hot water |
Electricity | £0.22 – £0.30 | Appliances, lighting |
Note: Prices vary slightly based on region, supplier, and tariff caps.
The reason gas is cheaper lies in how energy is produced and delivered. Gas has lower production and distribution costs, while electricity includes additional expenses such as grid infrastructure, renewable energy support, and transmission losses. These added costs make electricity significantly more expensive per unit.
Despite this, lower unit cost does not always mean lower overall spending. Gas boilers are less efficient because they lose energy during combustion, while electric systems—especially modern options like heat pumps—can convert energy more efficiently. As a result, electricity can sometimes offer better long-term value depending on how it is used in the home.
Why does electricity usually cost more than gas
Electricity usually costs more than gas in the UK because of the extra steps involved in producing and delivering it. Gas is supplied more directly and has lower production and distribution costs. Electricity, however, is generated from various sources and then transmitted through the national grid, with added costs for infrastructure, maintenance, and energy policies.
This difference is explained by the "spark gap," which shows the price ratio between electricity and gas. In the UK, electricity is typically 3 to 4 times more expensive per kWh than gas. This gap exists because electricity prices include network charges and environmental levies, while gas carries fewer additional costs.
As a result, when comparing whether gas is cheaper than electricity, the spark gap makes it clear why gas remains the cheaper option in most cases, even though electricity is becoming more important for future low-carbon energy use.
Gas vs electricity costs for different household uses
Energy costs in UK homes vary depending on how gas and electricity are used. While gas is generally cheaper per kWh, the real difference becomes clearer when comparing specific household activities like heating, cooking, and hot water. Efficiency, usage patterns, and appliance type all influence the final cost, not just the energy price itself.
Heating costs: gas boilers vs electric heating
Heating is the largest energy expense in most UK households, and gas boilers are usually more cost-effective than electric heating systems. Gas boilers heat water and distribute it through radiators with relatively low running costs per kWh. Electric heaters, on the other hand, use electricity directly, which is more expensive per unit of energy.
Heating Type | Average Cost (per kWh equivalent) | Efficiency | Typical Running Cost |
Gas boiler heating | Lower (£0.06–£0.08 gas price) | Moderate | Generally cheaper |
Electric heating | Higher (£0.22–£0.30 electricity) | High | Generally expensive |
Although electric systems can be more efficient, the higher electricity price usually makes them more expensive to run unless using modern heat pumps.
Cooking costs: gas vs electric hobs
Cooking costs are relatively small compared to heating, but gas hobs are still cheaper to operate in most cases. Gas provides instant heat control, which reduces wasted energy. Electric hobs, especially older coil types, consume more electricity and take longer to adjust temperature, slightly increasing costs.
Cooking Type | Average Running Cost | Efficiency | Cost Level |
Gas hob | Lower | High | Cheaper |
Electric hob | Higher | Moderate | More expensive |
Induction hobs are more efficient than standard electric hobs, but electricity prices still keep running costs above gas in most homes.
Water heating costs: gas vs electric systems
Hot water heating is another major energy use, and gas systems are usually cheaper for traditional storage tanks and combi boilers. Electric immersion heaters are simple but costly to run due to high electricity prices.
Water Heating Type | Average Cost | Efficiency | Overall Cost Impact |
Gas water heating | Lower | Moderate | More affordable |
Electric immersion | Higher | High | More expensive |
Heat pumps can change this comparison, but in standard UK homes, gas remains the cheaper option for water heating.
When electricity can be cheaper than gas
Electricity is not always more expensive than gas. In certain situations, it can actually work out cheaper overall depending on the type of system, efficiency of appliances, and energy source. This is especially true in modern, energy-efficient homes where electricity is used in smarter ways.
More efficient electric appliances
Electric systems like heat pumps and induction hobs can use energy far more efficiently than traditional gas systems. Heat pumps, for example, can produce multiple units of heat for every unit of electricity used, significantly reducing overall energy consumption and lowering running costs despite higher electricity prices.
Lower installation and maintenance costs
Electric systems often have simpler setups compared to gas boilers. They usually require less maintenance, no flues or gas pipework, and fewer safety checks. Over time, this can reduce overall household expenses, making electricity more cost-effective in the long run even if unit prices are higher.
Using renewable energy to reduce electricity costs
Households that use renewable energy sources such as solar panels can significantly cut electricity bills. When electricity is generated on-site, reliance on grid electricity decreases, making electric heating and appliances much cheaper compared to gas-dependent systems.
What determines whether gas or electricity is cheaper for your home
The cost of gas versus electricity in a home is not fixed, and it depends on several personal and external factors. While gas is generally cheaper per kWh, the actual bill you pay is influenced by how energy is priced, how efficiently your home uses energy, and the type of systems you rely on daily.
1. Energy tariffs and supplier pricing
Energy tariffs play a major role in determining whether gas or electricity is cheaper for your home. Suppliers set different unit rates and standing charges for both fuels, and these can vary depending on your contract, region, and the UK energy price cap. Some tariffs may reduce electricity costs during off-peak hours, which can make electricity usage more affordable in specific time periods.
2. Home insulation and overall efficiency
When considering whether electric heating is cheaper than gas, home insulation plays a key role. Well-insulated homes retain heat better, meaning less energy is required regardless of whether you use gas or electricity. Poor insulation increases energy demand, making both gas and electric systems more expensive to run.
3. Types of appliances you use
The type of appliances in your home significantly affects energy costs. Gas boilers are usually cheaper for heating, while electric appliances like heat pumps and induction hobs can be more efficient in converting energy into usable heat. Older electric systems tend to be more expensive to run, while modern high-efficiency devices can reduce overall electricity consumption.
4. Daily energy usage habits
Your daily habits also influence whether gas or electricity feels cheaper. Using heating only when needed, cooking efficiently, and avoiding unnecessary energy waste can lower costs. Time-of-use electricity tariffs can also make electricity cheaper during off-peak hours, especially if you shift usage to those periods.
