Why you can trust our integrated fridge freezer reviews

To keep our reviews impartial, we buy all the appliances we test from a regular shop, just as our members would. We don't accept freebies from PR companies or manufacturers.

We then put all the fridge freezers – integrated, freestanding and American – through a series of challenging trials in our test laboratory. Each test is designed to mimic how you might use your fridge freezer in real life. 

We routinely review our tests to ensure that we stay on top of market developments or changes in consumer expectations of appliances over the years.

Our reviews make it easy to compare your choice of models side-by-side – so you get the best model for your money.

At Which?, we always go the extra mile. Our lab tests of integrated fridge freezers include measurements of how much useable space you'll actually have (often not the same as claimed by the manufacturer), how much you'll spend on energy over the years and how long it takes for food to get down to a cold enough temperature to keep it safe to eat.

How to buy the best integrated fridge freezer

These questions will help you decide if an integrated model is right for you. 

  • Will you want to change your kitchen design in future? If there's a chance that you might change your layout, opt for a freestanding model. Find out more about kitchen planning.
  • How much are you willing to spend? Integrated fridge freezers tend to be more expensive. You'll have fewer good, cheap models to pick from than if you were buying a freestanding model.
  • Is a large capacity a priority for you? Integrated models tend to have less storage space than freestanding models. Ten shopping bags of groceries is the most any integrated model we've tested can hold, while freestanding ones can hold up to 23 bags.

What size integrated fridge freezer should I buy?

Kitchen with integrated appliances

You can buy models with various fridge-to-freezer ratios, so make sure you pick a size that will suit your fresh and frozen food needs. Most are similar in size to freestanding models – where the fridge is slightly larger than the freezer – but some have a large fridge and a relatively small freezer.

If you’re replacing an existing integrated fridge freezer, you’ll have to choose one with the same fridge-to-freezer proportions as your old one.

Integrated fridge freezer dimensions

Built-in models are usually designed to fit inside a standard 60cm-wide kitchen cupboard unit. They’re usually 55cm deep. Heights range from about 100cm to 200cm.
