Engineer shares four ‘biggest energy guzzlers’ in your home and how to save money on bills


Home appliances are expensive to run, but some more than others, especially in the current climate. 

However, homeowners and billpayers are being warned about the “biggest energy guzzlers”, with experts at Repair Aid claiming some can be “massive energy hogs”.

1. Dishwashers 

Convenient, speedy and luxurious, dishwashers are becoming an increasingly visible and valuable fixture in our modern, busy lifestyles. 

However, that time and convenience come at a price that goes beyond its retail price.

On average, dishwashers add £45 to your annual energy bill. If you want to cut down on your energy usage but want to own a dishwasher, consider washing up by hand now and then.

2. Fridge freezers

Despite requiring about five times less power, fridge freezers can end up being “more expensive than dishwashers”.

As fridge freezers are one of the few appliances that are in operation all day, every day. This means that they require a constant supply of electricity to keep food cool and frozen. 

Size plays a role in how much it costs to run a fridge freezer. While a low-capacity unit could cost around £40 per year, a larger-capacity appliance can end up costing you over £50 per year.

3. Electric ovens

While not requiring the constant supply of a fridge and/or freezer, ovens are “massive energy hogs when in use”. 

For example, running a 3,000 watt electric oven for half an hour every day can “add £90 to your annual bill”. 

A workaround for those looking to reduce their energy bills is to use your microwave as much as they can. 

This is because microwaves will only add about £3 to your annual bill if they are used 10 minutes per day.

4. Washing machines and tumble dryers

With washing machines, power consumption can depend on what function or type of cycle is being used. 

For example, a heat cycle can require 2,000W, a spin requires about 500W and a wash needs just 250W. 

It is also hard to pin down how much it costs to run a washing machine. A large family will run one or two washes a day; whereas someone living on their own may only use their washing machine once every few days. 

However, it’s thought that annual running costs can range from just over £10 to around about £50.
