How Energy Efficient Is Your Appliance? What A-Rating Means in 2025
In today’s world, energy efficiency is no longer just a “nice to have”—it’s essential. Whether you're upgrading your fridge, replacing an old dishwasher, or looking for a more efficient washing machine, knowing how energy ratings work can save you money in the long run. But with rating labels changing over the years, many people are left wondering: What does an A-rating actually mean in 2025? Is it the same as it was a few years ago? And how do you know if your current appliances are costing you more than they should?
At Mullen Domestic, we believe in keeping things simple and helping our customers in Northern Ireland make smart, informed choices, whether you're buying your first appliance or replacing one that's seen better days. Let’s unpack what you need to know about energy efficiency and how it applies to the appliances in your home.
Why Energy Ratings Matter (More Than Ever)
Energy efficiency isn't just about saving the planet, it’s also about saving you money.
Modern appliances are smarter, quieter, and more eco-friendly than ever before. But if you’re still using a fridge or washing machine that’s 10+ years old, you could be paying significantly more in electricity every month without realising it.
For families, couples, or anyone trying to reduce their household bills, energy-efficient appliances make a real difference.
What Does an A-Rating Mean in 2025?
The energy label system was revamped in 2021, dropping the confusing A+++, A++, and A+ labels and returning to a simple A–G scale. The idea was to make things clearer for consumers and leave room for future innovation.
In 2025:
-
A-rated appliances are now the most efficient on the market.
-
A current A-rating is harder to achieve than before, so if you see it, you know it’s top-performing.
-
B and C-rated models may still be very efficient, especially compared to older units.
Tip: Look for the coloured label on the product or online listing—green means more efficient, red means higher energy use.
How Different Appliances Stack Up in 2025
Let’s break down what efficiency means across the product ranges we offer at Mullen Domestic, from fridges to floorcare.
Fridges (Northern Ireland’s Everyday Essential)
Fridges and fridge freezers run 24/7, making them one of the biggest contributors to household electricity bills.
If your current fridge in Northern Ireland is more than 8–10 years old, replacing it could cut its energy usage in half, or more. Look for:
-
Frost-free technology (saves energy and time)
-
LED lighting (more efficient than halogen)
-
A to C energy ratings (best balance between performance and efficiency)

Laundry (Washing Machines & Tumble Dryers)
Washing machines have come a long way in terms of eco performance. Many now feature:
-
Eco Wash settings
-
Load sensors
-
Low temperature cycles that still clean effectively
A modern A or B-rated washer uses far less water and electricity than older models. For dryers, heat pump technology is the gold standard for efficiency.

Cooking Appliances (Ovens, Hobs, Microwaves & more)
While ovens aren't the biggest energy consumers, a poor-quality or older model can still waste plenty of electricity.
Modern ovens often come with:
-
Efficient fan-assisted cooking
-
Quick heat-up modes
-
Multifunctional settings to avoid overuse
Look for the energy label on both built-in ovens and freestanding cookers.

Dishwashers
Modern dishwashers are surprisingly efficient, often using less water than washing by hand, especially on eco mode.
In 2025, energy labels for dishwashers will be based on:
-
Electricity use per 100 cycles
-
Water consumption
-
Drying performance
An efficient model can save water and energy without compromising on clean dishes.

Small Appliances
From kettles and microwaves to vacuum cleaners, small appliances also benefit from energy-efficient innovation.
-
Induction hobs heat faster and use less power than traditional electric models
-
Eco kettles boil just the amount of water you need
These small changes can add up over time, especially in a busy household.
