Five of the best eco fridge freezers

Fridge freezers are one of the most energy-hungry appliances in the home so, as they are working 24/7, it’s important to choose a model that is as efficient as possible for your budget.

One of the quickest ways of doing this is by looking at an appliance’s energy rating. The scale goes from A to G, with A being the most energy-efficient. You will typically spend more upfront on a higher-rated appliance but it will ultimately save you money on bills later down the line.

Another consideration when it comes to efficiency is size and capacity. What do you stock up on most in your household? Are you a keen cook and love fresh produce? Or do you like having a good stash of frozen options for easy weeknight dinners? This will help you decide which fridge freezer ratio best suits your needs.

Smart ‘no frost’ technology for the freezer and climate control settings in the fridge can also help keep energy usage down and ensure food stays fresh for longer.

The five eco fridge freezers that we’ve selected sit in the middle of both the price and efficiency scales. We’ve chosen these models to help save you money up-front as well as in the long term.
