With energy prices soaring many of us are looking at ways to reduce our energy usage before it gets to the point of choosing between heating and eating. One cost-cutting measure you might be considering is using your kettle less, but just how much does it cost to boil a kettle?

How much does it cost to boil a kettle

Why boil the kettle?

It might seem obvious that you could be boiling the kettle for hot drinks like tea and coffee throughout the day, especially if you are at home during the day. 

However, there are lots of other reasons you might be boiling your kettle throughout the day.

You might find yourself boiling the kettle to use the water for cooking, such as cooking pasta, potatoes or boiling eggs. 

How much does it cost to boil a kettle?

With rising energy prices you might be wondering just how much your kettle costs to boil.

This will depend on your kettle and the amount you pay for your electricity, but let’s use a few average examples.

How much does it cost to boil a kettle

In November 2021 the average price for electricity was 20.06 pence per kWH which stands for kilowatts per hour. Let’s round that down to 20 pence per kWH.

The amount of electricity your kettle uses will depend on the element within your kettle.

For example, this kettle from Amazon uses 3000W (That’s 3,000 watts, or 3 kilowatts) per hour and it takes 43 seconds to boil one cup of water.

This means that the kettle would use 60p per hour of constant boiling, or 1p per minute. Since it takes less than a minute to boil one cup of water you are looking at a cost of less than 1p per boil.

For one cuppa a day, only boiling the water you need that’s around £2.74 in energy.

If you were to boil a litre of water in around 2 and a half minutes then you can expect to pay 2.5p each time.

You might think that finding a kettle with a 2500W element would reduce the cost, however it would then take longer for your water to boil which means you are almost cancelling out any savings by choosing a kettle with a lower Wattage.

How to reduce the cost of boiling the kettle

Now that you know the answer to ‘how much does it cost to boil a kettle?’ you might be wondering if there are ways to reduce your energy usage, and therefore the cost of boiling your kettle.

The most effective way to reduce the cost of boiling your kettle is to only boil as much water as you need.

Overfilling your kettle is just a waste of money as you are using energy you don’t need to – and therefore paying for energy you don’t need to pay for.

Get a thermos?

Many people have debated buying a thermos to keep their boiled water hot all day, however at a cost of under 1 pence per boiled cup of water we can’t see buying a thermos saving you much money when you take into account the initial outlay for your thermos.

Our verdict

With boiling a kettle for a cuppa costing less than 1 pence we would advise looking for other ways to reduce your energy usage and save money rather than limiting your hot drinks. After all, having a hot drink to keep warm might stop you from needing to put the heating on and spending even more money.

We would suggest looking at other ways to save money on your energy instead.

Other ways to save money on energy usage

There are plenty of other ways to save money on your energy usage by using less energy.

A top tip is to turn off your appliances when they are off instead of relying on standby mode. Even though the main appliance is off the standby mode still uses energy – you are paying for literally nothing.

Consider investing in a heated throw which costs around 6 pence per hour to run instead of turning the heating on.

Use candles to create light and heat within your home.

Switch your lightbulbs to LED.

Turn off the lights in rooms you aren’t using.
