How Energy Ratings Impact Your Fridge Freezer’s Energy Use—and Your Wallet
Thinking about buying a new fridge freezer? Before you get swayed by sleek designs or tempting price tags, there’s a crucial factor you shouldn’t overlook: the appliance’s energy efficiency rating. Not only does this rating affect how much electricity your fridge freezer consumes, but it also has a significant impact on your energy bills over time.
Grab a cuppa, and let’s break down how different energy ratings—from A to G—translate into energy consumption and, more importantly, what that means for your wallet.
Understanding Energy Efficiency Ratings
First things first—what’s the deal with these energy ratings?
In March 2021, the UK updated its energy labelling system to make it simpler and more transparent. Appliances are now rated on a scale from A to G:
- A (Dark Green): Most energy-efficient appliances.
- G (Red): Least energy-efficient appliances.
Key Points:
- Stricter Standards: The new scale is tougher, so an appliance that was previously rated A+++ might now be a C or D. Don’t panic—it’s still efficient!
- Future-Proofing: This change encourages manufacturers to develop even more energy-efficient technologies.
Note: Currently, very few fridge freezers achieve an A, B, or C rating under the new system. Most models are rated between D and G. However, understanding the full range of ratings helps you make informed decisions now and in the future.
Energy Consumption by Rating
Let’s see how much energy fridge freezers consume annually based on their energy efficiency rating. These figures are approximate and based on typical models available in the UK as of October 2024.
Annual Energy Consumption:
- A-Rated Fridge Freezer: 100 kWh per year
- B-Rated: 120 kWh per year
- C-Rated: 150 kWh per year
- D-Rated: 180 kWh per year
- E-Rated: 220 kWh per year
- F-Rated: 270 kWh per year
- G-Rated: 320 kWh per year
Note: Actual energy use may vary based on the appliance’s size, features, and how you use it.
What Does This Mean for Your Wallet?
Time to talk money! Let’s calculate the annual running cost of fridge freezers at different energy ratings. We’ll use the average UK electricity price of 25p per kWh (as of October 2024).
Annual Running Costs:
- A-Rated Appliance:
- Energy Use: 100 kWh
- Annual Cost: 100 kWh × £0.25 = £25
- B-Rated Appliance:
- Energy Use: 120 kWh
- Annual Cost: 120 kWh × £0.25 = £30
- C-Rated Appliance:
- Energy Use: 150 kWh
- Annual Cost: 150 kWh × £0.25 = £37.50
- D-Rated Appliance:
- Energy Use: 180 kWh
- Annual Cost: 180 kWh × £0.25 = £45
- E-Rated Appliance:
- Energy Use: 220 kWh
- Annual Cost: 220 kWh × £0.25 = £55
- F-Rated Appliance:
- Energy Use: 270 kWh
- Annual Cost: 270 kWh × £0.25 = £67.50
- G-Rated Appliance:
- Energy Use: 320 kWh
- Annual Cost: 320 kWh × £0.25 = £80
Annual Cost Differences:
- Between A and D-Rated: £45 – £25 = £20 more per year
- Between A and G-Rated: £80 – £25 = £55 more per year
- Between D and G-Rated: £80 – £45 = £35 more per year
Long-Term Savings Over the Appliance’s Lifetime
Most fridge freezers have a lifespan of about 10 years. Let’s see how the savings stack up over a decade.
- A vs. D-Rated:
- Extra Cost Over 10 Years: £20/year × 10 = £200
- Total Savings with A-Rated: You save £200 over 10 years by choosing an A-rated appliance over a D-rated one.
- A vs. G-Rated:
- Extra Cost Over 10 Years: £55/year × 10 = £550
- Total Savings with A-Rated: A significant £550 saved over a decade!
- D vs. G-Rated:
- Extra Cost Over 10 Years: £35/year × 10 = £350
- Total Savings with D-Rated: You save £350 over 10 years compared to a G-rated appliance.
The Bigger Picture: Purchase Price vs. Running Costs
You might be thinking, “But aren’t higher-rated appliances more expensive to buy?” Let’s crunch some numbers.
Example Scenario:
Option 1: D-rated fridge freezer costing £500.
- Running Cost Over 10 Years: £45/year × 10 = £450
- Total Cost: £500 + £450 = £950
Option 2: A-rated fridge freezer costing £700.
- Running Cost Over 10 Years: £25/year × 10 = £250
- Total Cost: £700 + £250 = £950
Total Savings with A-Rated Appliance:
- Savings Over 10 Years: £950 (both appliances have the same total cost over 10 years)
In this scenario, although the A-rated appliance costs £200 more upfront, the lower running costs balance out over the appliance’s lifetime.
What About B and C-Rated Appliances?
Let’s include them in our comparison:
Option 3: B-rated fridge freezer costing £650.
- Running Cost Over 10 Years: £30/year × 10 = £300
- Total Cost: £650 + £300 = £950
Option 4: C-rated fridge freezer costing £600.
- Running Cost Over 10 Years: £37.50/year × 10 = £375
- Total Cost: £600 + £375 = £975
Comparing Costs:
- B-rated Appliance: Total cost over 10 years is £950.
- C-rated Appliance: Total cost over 10 years is £975.
- D-rated Appliance: Total cost over 10 years is £950.
In this case, the B-rated appliance offers the same total cost over 10 years as the A and D-rated models but with a balance between upfront cost and running expenses.
Tips for Choosing an Energy-Efficient Fridge Freezer
- Check the Energy Label:
- Aim for appliances rated A to C for the best energy efficiency. While A-rated models might be pricier, they offer significant long-term savings.
- Size Matters:
- Choose a size that fits your needs. Larger appliances consume more energy.
- Consider Features:
- Additional features like ice makers and digital displays can increase energy consumption.
- Research Brands and Models:
- Look for brands known for energy efficiency and reliability.
- Think Long-Term:
- Consider both the purchase price and the running costs over the appliance’s lifetime.
Environmental Benefits
Opting for a higher-rated appliance doesn’t just save you money—it also reduces your carbon footprint. Energy-efficient appliances consume less electricity, leading to fewer carbon emissions from power plants.
Final Thoughts
When shopping for a new fridge freezer, it’s tempting to focus on immediate costs or flashy features. However, considering the appliance’s energy efficiency rating is crucial for long-term savings and environmental impact.
By investing a bit more upfront, you can enjoy lower energy bills for years to come and contribute to a greener planet.
