An integrated fridge freezer can keep your fitted kitchen looking flash, but will it keep your food fresh? We reveal the best and worst built-in models.

Integrated fridge freezers have become more popular in recent years, as people opt to keep their home appliances hidden behind fitted kitchen cabinets. But our tests reveal that good ones are still few and far between.

We’ve uncovered over 70 Best Buy fridge freezers, but only a handful of these are built-in models, so it’s essential you do your research before you buy one. We’ve rounded up some of the best below, with prices starting at less than £400. We’ve also picked out three of the worst to give you an idea of what to avoid.

Top five integrated fridge freezers

    £829.00

    The freezer isn’t big or powerful enough to freeze large quantities of fresh food, but the spacious fridge has no problems cooling food quickly. It’s very easy to clean and the digital controls make selecting the right temperature a breeze.

    This fridge freezer has plenty of features, including a frost-free freezer, and the fridge is spacious with 145 litres of usable space, which is around eight standard bags of supermarket shopping. It did well in most of our tough tests, it chills and freezes rapidly, is great at keeping the temperature stable, it's really easy to clean and is very efficient. The thermostat isn't the most accurate, though.

    Integrated fridge freezers tend to cost more than freestanding models, but that doesn’t meant they have to cost more to run. It chills rapidly, has excellent temperature stability and a reliable thermostat. It's very quiet, easy to use and has a flame-retardant backing. In almost every respect this is an excellent fridge freezer. It's let down by a sluggish freezer, but not enough to stop it being a Best Buy.

    This fantastic integrated fridge freezer does everything it should, and does it brilliantly. It’s powerful, accurate and energy efficient, and so quiet you’ll barely know it’s there. This high-scoring brand ticks every box and is an impressive Best Buy. It's not a budget option, though.

    Don’t be put off by the fact that this fridge freezer has been around several years. It’s still widely available, which is no surprise, as not only is it exceptional at storing your fresh and frozen food in top condition, but it’s also quiet, has an accurate thermostat and is cheaper than other Best Buys. Do bear in mind, though, that it was reviewed before we changed our test slightly in April 2018, so the results aren’t directly comparable with others in this table.

Integrated fridge freezers to avoid

They may look similar, but don't assume that all integrated fridge freezers provide an equally good home for your food. Our tests have uncovered built-in models that will push up your energy bills without even cooling effectively. Read on for the integrated fridge freezers to avoid to make sure you don't end up with a dud product.

    £539.00

    This low-scoring integrated fridge freezer has a few plus points but, unfortunately, the areas where it struggles happen to be some of the most important. This model manages to have a fridge and freezer that lack power and energy efficiency could be better.

    This isn’t a terrible fridge freezer – provided your kitchen always stays at one stable temperature throughout the year. If not, you’re going to have a problem. Whenever the temperature in your kitchen drops on a cold night, or soars during a heatwave, the temperature inside this fridge freezer will fluctuate wildly. This isn’t going to do your food any favours, to say the least. It's also very energy inefficient for its size.

    This fridge freezer isn't energy efficient and can't maintain a stable temperature in warm rooms. What's more, the thermostat can't be trusted, so you'll need to invest in a fridge thermometer to check whether the fridge is cold enough to keep your food safely chilled. Definitely steer clear of this one.

Integrated vs freestanding fridge freezers

Choosing a fridge

If you can’t decide between a built-in and freestanding model, bear in mind that integrated fridge freezers tend to cost more than freestanding ones, and yet almost always contain less storage space.

At the time of writing, the built-in models we’ve tested cost £721 on average and contain around 182 litres of usable space – enough for around nine supermarket carrier bags' worth of fresh and frozen food. By comparison, the average freestanding fridge freezer costs £667 and contains 236 litres (around 12 carrier bags) of usable space.

Which? fridge freezer reviews

Modern kitchen with integrated fridge freezer

You may well wonder how good or bad a fridge freezer can really be. They all chill and freeze your food, after all. But you’d be surprised.

Every fridge freezer we review is subjected to nine weeks of intensive and independent testing, so you can have complete confidence in our recommendations.

Chilling and freezing tests

The worst models chill and freeze several times more slowly than the best, giving heat-loving bacteria several extra hours to tuck in to your food. As a result, food in the fridge will quickly lose its freshness, while the flavour and freshness of the food you freeze is also less likely to be preserved.

How we test fridge freezers

Our tests also reveal that many models struggle to maintain a safe and steady temperature when the temperature in your kitchen changes. Ever woken up to half-frozen orange juice after a cold night, or found freezer burn on food that had been perfectly frozen? Poor temperature stability could be the reason. The temperature in the best models fluctuates by less than half a degree in cold and warm room conditions.

We also perform an array of tests on the thermostat, as well as assessing how efficient and noisy each fridge freezer is, as well as how easy they are to use and clean .
