Kitchen appliance energy usage

gas vs induction summary

In the current climate with spiralling energy costs, were often asked about the cost of running typical kitchen appliances.

If you know the power consumption of your appliance you can use our calculator above to find out how much energy you are likely to use over time.

If you haven’t got time for that, here are some quick facts for you on a couple of popular kitchen appliances…

Gas vs Induction

Is it cheaper to use a gas or induction hob?

From 1 October 2022, if you’re on a standard variable tariff paying by direct debit, the average unit price will be frozen at:

  • 34.0p/kWh for electricity.
  • 10.3p/kWh for gas.

According to research from Defra, the average power consumption to cook the same chicken stir fry was:

  • Induction 0.32kW (10.88p).
  • Gas – 0.67kWh (6.9p).

So to cook this chicken stir fry it would be 3.98p cheaper to use gas.

Why is induction a popular choice?

Even though gas may be cheaper, many people prefer to use induction as a method of cooking. The reasons include:

Safety first – Induction hobs contain a system that detects when a pan is in place meaning no heat is produced when the hob is empty and there is no flame or element to ignite fumes or cause burns. A great selling point for families with small children.

Flexible cooking zones – Some induction hobs have extended cooking zones that break the boundaries of the usual four area hob. This allows you to use less traditional pots or dishes such as a teppanyaki or griddle plate.

Easier to clean – Induction hobs have a completely flat surface meaning they are easier to clean and maintain with no gaps to hide spills.

Greener – Induction cooking is more efficient than traditional methods as heat is channelled into the pan itself, cooking the food faster and using less power. Gas systems produce damaging carbon emissions. With climate targets increasing, gas could become obsolete in a matter of years. Electric heating is clean and respectful to the environment. It does not emit polluting gases or use heavy metals.

Dishwasher energy efficiency

gas vs induction summary

According to the consumer choice champion Which? – Dishwashers are, on average, four times more water efficient than washing by hand.

Should you opt for the most water-efficient full-sized dishwasher, expect almost 10 times less water to wash the same amount of dishes as hand washing them.

Dishwashers use on average use about 1.12kWh of energy per wash. This costs roughly 38p, based on £0.34p per kWh.

  • Dishwashers don’t just wash one or two place settings at a time. Some can wash many more, up to 16 in one wash!
  • If you have enough dishes, you can wait until the dishwasher is full before running a cycle, saving more water and energy.
  • Even the least water efficient dishwashers can wash twice as many dishes using the same amount of water.


When it comes to selecting your kitchen appliances there are multiple options to help keep your kitchen as energy efficient as possible. Sometimes, its about personal preference but if you are armed with the energy facts, your appliance choice becomes much more considered and there are no surprises.
