Appliance Energy Efficiency Ratings Online Energy Guides

What Are Appliance Energy Efficiency Ratings?

Appliance energy efficiency ratings are standardized labels that indicate how much energy a household appliance consumes. These ratings help consumers choose more efficient models, reducing energy consumption and saving on utility bills. In the UK, these ratings are an essential part of purchasing decisions for appliances like refrigerators, washing machines, dishwashers, and TVs.

The energy efficiency of appliances is measured on a scale from A to G, where A is the most efficient and G is the least efficient. This rating provides a quick reference to understand how an appliance’s energy use compares to others in its category.

How Do Energy Efficiency Ratings Work?

Energy efficiency ratings are based on standardized testing procedures for each type of appliance. Each product is evaluated for its energy consumption in kilowatt-hours (kWh) over a given period of time, such as a year, or per usage cycle (for washing machines or dishwashers). The results are then placed on the A to G scale.

In 2021, the UK switched back to the simpler A to G scale, removing the previous A+, A++, and A+++ labels. This reset the rating system to account for advances in technology and energy efficiency. Older labels, which had extended beyond A to A+++, were becoming less useful as more appliances received the top rating.

What Information Does an Energy Label Include?

An energy efficiency label provides the following information:

Energy Efficiency Rating: A large letter (A to G) prominently displayed to show the product’s overall efficiency.
Annual Energy Consumption: Typically shown in kWh per year (for products like refrigerators) or kWh per 100 uses (for washing machines, dishwashers).
Product-Specific Data: This varies based on the appliance, but could include information like water usage, storage capacity, noise levels, or screen size (for TVs).
QR Code: Many modern labels include a QR code, which provides access to more detailed information online.
Other Key Indicators: Depending on the appliance type, labels may also show noise levels, capacity, or other relevant data.

Why Are Energy Efficiency Ratings Important?

Reduced Energy Bills: Appliances with better energy ratings use less electricity, leading to significant cost savings over their lifetime.
Lower Environmental Impact: Energy-efficient appliances consume less power, which translates to lower carbon emissions and a smaller environmental footprint.
Long-Term Investment: While energy-efficient appliances may have a higher upfront cost, they often pay for themselves over time through reduced energy consumption.
Legal Requirements: Landlords and property owners are often required to consider energy efficiency when fitting new appliances, as it can affect property value and appeal.

Energy Ratings Explained by Appliance Type

The ratings do vary slightly by appliance type and some categories of appliance dont have a rating system at all.

1. Refrigerators, Freezers, and Fridge-Freezers

Energy Ratings: A to G
Annual Energy Consumption: Shown in kWh/year

Refrigerators and freezers are operational 24/7, so choosing an efficient model can have a huge impact on energy use. A higher-rated fridge-freezer can save hundreds of pounds over its lifetime.

Choosing the Right Size: Larger models will use more energy, even if they have the same efficiency rating. For example, a smaller A-rated fridge may use less energy than a large one rated A.
Energy Consumption: The energy label shows annual kWh usage, which can help you estimate running costs. For example, a fridge-freezer rated A could save up to £330 over its 17-year lifespan compared to a lower-rated model.

2. Washing Machines

Energy Ratings: A to G
Energy Consumption: Shown in kWh per 100 washes

Washing machines are rated on their energy use for 100 cycles of a standard 40-60°C wash. Efficient models also help reduce water usage.

Savings: Opting for an A-rated washing machine over a D-rated one can save approximately £85 over its 11-year lifetime.
Usage Tips: Washing full loads and using lower temperature settings will further reduce energy consumption.

3. Dishwashers

Energy Ratings: A to G
Energy Consumption: Shown in kWh per 100 cycles

Dishwashers make up around 8% of the average household electricity bill. Energy-efficient models can help reduce both electricity and water use.

Cost Impact: An A-rated dishwasher can save around £20 annually compared to a lower-rated model.
Efficiency Features: Look for eco-friendly wash settings that use less water and energy, and only run the machine when it is full to maximize efficiency.

4. Televisions

Energy Ratings: A to G
Energy Consumption: Shown in kWh per 1,000 hours of use

Television energy consumption is mainly determined by screen size and display technology. Larger TVs use significantly more energy, regardless of their rating.

Annual Running Costs:
- A 60” G-rated TV could cost up to £65/year to run, while a 32” F-rated TV could cost just £14/year.
Tech Types: LED TVs are generally more efficient than older plasma models. OLED and QLED TVs, while offering superior picture quality, tend to consume more energy.

5. Tumble Dryers

Energy Ratings: A+++ to D
Energy Consumption: Shown in kWh per cycle

Tumble dryers are typically energy-intensive, but there are ways to minimize their impact. Models with heat pumps are among the most energy-efficient.

Savings Potential: A heat pump dryer rated A+++ could save around £650 over its 13-year lifetime compared to a lower-rated machine.
Dryer Features: Choose models with moisture sensors that stop the machine once the clothes are dry, reducing energy waste.

6. Ovens

Energy Ratings: A+++ to G (Older scale)
Energy Consumption: Shown per use

Ovens do not use the new A-G rating system, but older models are still rated from A+++ to G. The most efficient options are typically fan-assisted ovens, which use less energy by circulating hot air.

Energy-Saving Tips: Using a fan-assisted oven allows you to cook at lower temperatures, and ovens with triple-glazed doors retain heat better, reducing cooking time.
Self-Cleaning Features: Ovens with pyrolytic self-cleaning functions are more energy-intensive, as they burn off food residue at high temperatures.

Appliances Without Energy Ratings

Not all appliances come with energy efficiency ratings. However, you can still make choices that reduce their energy consumption. Examples include:

Microwave Ovens: Microwaves are more energy-efficient than traditional ovens when heating small amounts of food.
Kettles: Boil only the water you need to save energy.
Smart Speakers and Computers: Unplug these devices when not in use or use smart plugs to avoid standby power consumption.

How to Compare Energy Efficiency Labels

When comparing appliances, always check the kWh energy consumption figure for an accurate comparison. A larger appliance with the same energy rating as a smaller one may still use more power because of its size. Also, keep in mind that newer models are generally more energy-efficient than older versions.

How to Choose the Most Energy-Efficient Appliance

Consider Size: Larger appliances generally use more energy, even if they have a good efficiency rating. Choose the smallest size that meets your needs.
Look at the kWh Figure: The energy rating is useful, but the actual energy consumption in kilowatt-hours (kWh) will give you the clearest idea of how much it will cost to run the appliance.
Use Energy-Saving Features: Many appliances have eco modes, timers, or sensors that help save energy by optimizing performance.
Invest in Smart Technology: Smart thermostats, washing machines, and other appliances that you can control remotely often help reduce unnecessary energy consumption.

Final Thoughts

Choosing energy-efficient appliances is a smart investment for both your wallet and the environment. By understanding the energy rating labels and considering how often you’ll use the appliance, you can make informed decisions that save energy, reduce your bills, and lower your carbon footprint.
