Boiling a kettle using gas is generally cheaper than using electricity.
For those who are interested in more details
Boiling a kettle is a common activity in households worldwide, but the choice of energy source for this task can significantly affect your monthly bills. According to the UK Energy Saving Trust, gas is cheaper than electric for heating water, as electricity is usually more expensive than gas. This is because the majority of the UK’s electricity comes from burning gas and coal, which is less efficient than using gas directly.
A study by the National Institute of Standards and Technology found that boiling a full kettle (roughly 1.5 liters) of water using an electric stove took an average of 4.88 minutes and consumed 0.13 kWh of electricity. Boiling the same amount of water using a gas hob took about 4.15 minutes and consumed 0.11 kWh of gas. This difference may seem small, but it can add up over time.
Interestingly, the study also found that electric kettles are more efficient than stove-top kettles. Electric kettles use about half the energy of an equivalent stove-top kettle to boil the same amount of water.
In terms of environmental impact, gas is a fossil fuel and produces greenhouse gases when burned. However, a more efficient gas boiler produces less carbon dioxide than an equivalent electric boiler.
In conclusion, boiling a kettle using gas is generally cheaper than using electricity. According to Martin Lewis, founder of MoneySavingExpert.com, “it takes three times as much energy to produce energy through burning coal or gas than it does through nuclear or renewables. So, using natural gas to boil your kettle is likely to be better for the environment than electricity from a coal-fired power station.”
Here is a table summarizing the energy consumption and time taken for electric and gas kettles to boil the same amount of water:
| Electric kettle | Gas hob | |
|---|---|---|
| Time | 4.88 minutes | 4.15 minutes |
| Energy | 0.13 kWh | 0.11 kWh |
| Efficiency | Less efficient | More efficient |

This video compares the energy usage of gas and electric kettles when boiling water for tea. The presenter found that while the gas kettle is more efficient with small amounts of water, the electric kettle is better for larger quantities. The presenter also recommends using lower heating options on electric kettles for energy savings. If all cups of tea made each day switched from gas to electric kettles, the energy saved could be significant, but the type of energy used to power the electric kettle affects its carbon footprint. The video ends with a call-to-action to promote sustainable tea practices.

Which is more energy efficient – boiling water using an electric kettle, a kettle on a gas hob or a microwave oven? IT TAKES the same amount of energy to heat one litre of water no matter which method of heating used. The only difference in the methods is the amount of time each takes.
Because gas is cheaper than electricity, it works out slightly cheaper to boil water on a gas hob than using an electric kettle, as long as you are boiling just the quantity you need and switch off the hob as soon as it has boiled.
If you’re heating your house then using a gas hob to boil a kettle is always going to be much more economical. The waste heat just goes towards contributing to home heating at 100% efficiency, and of course gas is much cheaper than electricity anyway.
Gas is inefficient, but cheaper. The reason being the energy derived from gas is direct signel step process. Whereas electriccity production involves many stages , where gas is burned to produce the electricity, and then the electricity is convereted into heat energy in the kettle. Counting the efficinecy of the turbine, genrator, trasmission line, heating element, heat lost to surroundings etc., boiling a kettle with gas is more efficient and cheaper. If you only consider the efficiency of conversion from electricty to heat electrical heating would appear to be an efficient process.
Still, electrical energy is clean and easier to transport.
Furthermore, people ask
Is it cheaper to boil a kettle with gas or electricity? Response to this: When you take into account the cost of gas and electricity, we found that it’s cheaper to boil water on a gas hob than in an electric kettle.
Just so, What is the most energy efficient way to boil a kettle?
Response will be: Different temperature settings
For those that don’t need their drinks at exactly 100°C, boiling water to 90°C will save on your energy consumption over time.
What is the most economical way to boil water?
The answer is: An induction stove or hot plate is about 85 percent efficient. It creates an electromagnetic current directly in a pot to generate heat, losing very little to the air.
Is it cheaper to boil water in a kettle or use a gas boiler? In reply to that: It costs less to keep a water boiler hot than it does to constantly refill and boil a kettle. This is because your kettle uses a large amount of energy for a short amount of time, whereas a hot water boiler uses a smaller amount of electricity for a larger amount of time.
Is it better to boil a kettle on gas or electric?
Answer to this: Electric kettles are slightly more energy-efficient, coming in at around 80%, vs 70% efficiency on the stovetop. However, this is evened out by the fact that gas is cheaper per unit than electric. Then you need to factor in the fact that stovetops take longer to boil water vs an electric kettle. Is it cheaper to boil a kettle on gas or electric?
Thereof, Should you buy an electric kettle or a gas hob? With an electric kettle, all the energy goes into heating the water, bar a very small amount if there is an LED light. With a kettle on a gas hob, some of the energy escapes directly into heating the air around the kettle. With both types, the biggest money saving point is to only boil the amount of water you need and no more.
Similarly, How long does it take to boil a kettle? The reply will be: In the end it comes down to those two main criteria: boil quickly; keep the handle cool. Given this, I think America is living in the past. According to the tests I conducted (using a gas range at highest heat), our traditional stove-top kettles take eight or nine minutes to boil a mere four cups of water.
People also ask, How much electricity does a kettle use?
Answer to this: Kettle: around 2p to boil a full kettle: The average kettle holds 1.5 litres of water and uses about 0.1 kWh of electricity to boil for 3 minutes. That’s around 2p every time you boil a full kettle.
Correspondingly, Is it better to boil a kettle on gas or electric? Response: Electric kettles are slightly more energy-efficient, coming in at around 80%, vs 70% efficiency on the stovetop.
