We’re all watching our energy bills, but did you know you could make savings that more than cover the upfront cost just by choosing models that are energy efficient?
All of our energy cost data comes from our independent lab testing; every appliance we review is tested in real-world scenarios to measure how much energy it will truly cost to run.
We find big differences between seemingly identical A-rated machines, and even B and C-rated machines that cost less to run.
To make sure you know the true cost of an appliance, you need to check our running cost tools before buying.

Make big savings with an energy efficient tumble dryer
Heat pump tumble dryers do tend to cost more than cheaper condenser and vented models, but can easily pay for themselves in the energy savings in just five or six years.
What’s more, choosing an inefficient dryer could add a significant amount to your yearly bills, and even more over the course of its life.
We calculate the annual cost of every dryer we review, based on drying three full loads on the cotton and cupboard dry settings per week. This way you can know which will make drying an easy task rather than a costly one.
Use our tumble dryer running cost tool to find out which dryer is actually cheapest.
Save with an energy efficient fridge freezer
Typically freestanding fridge freezers cost less to run than larger American fridge freezers.
Add in that American models are usually a pricey investment on their own, and they can easily cost hundreds if not thousands more than a freestanding model. That’s why, before buying, it’s worth thinking about how much space you have and need and then working backwards: what’s the most efficient and best fridge-freezer that I can fit in my kitchen?

Choose an energy efficient washing machine
Two of the biggest things that affect a washing machine’s energy and water use is its capacity and how thoroughly it actually cleans.
Of course you don’t want a washing machine that costs pennies to run that can’t clean clothes properly, but you also don’t want a washing machine that hikes up your bills.
This doesn’t have to be the case, though. We’ve found brilliant Best Buys and Eco Buys that balance energy and water efficiency with fantastic cleaning, rinsing and spinning.

How to pick an energy efficient dishwasher
Dishwashers can be some of the most energy-intensive appliances in our home, with many of us using it almost every day.
Our testing shows that the average full-size dishwasher costs £63 per year, doing five washes per week. As such it’s not a surprise you can reap big savings by choosing an energy-efficient model – easily enough to pay for a whole new dishwasher over its lifetime.
The best bit is that (unlike with washing machines) how much energy a dishwasher uses doesn’t have an effect on how well it cleans; some of the most efficient dishwashers we’ve ever found are brilliant Best Buys and Eco Buys.

Opt for an energy efficient oven
Ovens tend to be some of the longest-lasting appliances. Our surveys have shown that on average people keep their ovens for more than 20 years.
As such, it’s important to buy an efficient one – saving you £500 over the oven’s lifetime. This is based on using a fan oven for about five hours per week at 170°C.
To minimise your carbon footprint, we also recommend buying an electric model over a gas model.
