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.

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 ratio of fridge to freezer space do you want? Fridge freezers are often advertised using the ratio of fridge to freezer space, such as 60/40, 70/30 or 80/20.
• What features are important to you? Features tend to add to the cost of a model, so think about what is important to you and what you will actually use.

What size integrated fridge freezer should I buy?

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.

How much do integrated fridge freezers cost?

Cheaper brands (that make appliances for £500 and under) include Beko, Candy, Fridgemaster, GoodHome, Hisense, Hoover, Hotpoint, Indesit, Kenwood and Logik.

Increasing your budget to £900 means you'll also be able to pick from a fair number of Bosch, Haier, Liebherr, Samsung and Siemens models. 

Liebherr, Miele, Neff and John Lewis make models at the premium end of the price spectrum. 

The average cost of an integrated fridge freezer is higher than a freestanding model.

How do you install an integrated fridge freezer? 

Two different types of hinge systems can be used to attach the fridge freezer doors to the cabinetry during installation so that they can open together.

• Sliding door system This is where the cabinet door isn't directly fixed to the fridge door, but is instead fixed on rails.
• Door-on-door system This system only involves one hinge, where the fridge door is attached directly to the cabinet door. This means there's no space between the fridge and cabinet doors, and the fridge door sits flush with the cabinet.

The door-on-door system tends to be sturdier than the sliding door system, and allows you to open the doors much wider than a door on rails. Many fridge freezers are only suitable for installation in one system or the other, so be sure to check which one it is if you want to use a particular system.

Whichever type you choose, we'd recommend getting a professional to install your integrated fridge freezer for you. It's important to ensure the space is the correct fit for your fridge freezer, and when fitting the fridge freezer doors to your cabinet, it's vital to make sure that the appliance is level. It can also be difficult to manoeuvre the fridge freezer into the cabinet space.

Some retailers will install your integrated fridge freezer for you after you've bought it, although this service usually costs extra.
