Fridge freezers are bought in a hurry more often than any other large appliance, usually because the old one has died. That is exactly when people make the expensive mistakes — ordering something that will not fit through the door, or choosing an integrated model when the kitchen was built for freestanding.
This guide works through it properly: the three formats, how to read the capacity figures, and the handful of specifications that genuinely affect how well your food keeps.
The three formats
Integrated
Built into a kitchen unit behind a cabinet door, so the appliance disappears into the run. The cleanest look, and the right choice in a fitted kitchen designed around it.
The trade-off is capacity. The housing unit takes up space, so an integrated fridge freezer holds noticeably less than a freestanding one occupying the same floor area. You are paying for the look, and it is a fair trade if that is what you want.
Standard UK integrated housings are usually 177–178cm tall for a full column. The Smeg 70/30 integrated frost free and the CDA CRI971 integrated 70/30 are the common configuration; the Smeg 50/50 integrated gives you more freezer.
If your kitchen is planned around separate columns, a tall larder fridge with a separate freezer elsewhere gives more usable fridge space than a combined unit — see the Smeg integrated in-column tall larder fridge or the Liebherr IRBbi5150 with BioFresh.
For a small kitchen or a utility, the Smeg built-in under-counter fridge with ice box sits under a worktop.
Freestanding
Stands on its own, typically 60cm wide, and can go anywhere with a socket and ventilation space. More capacity for the money, easier to replace later, and you take it with you if you move.
It has to look like an appliance, which some people want. The Smeg FAB50 50s Retro Style leans into exactly that — at 481 litres it is a genuine full-size fridge freezer that happens to be a design piece.
American style
Two tall doors side by side, or a two-door two-drawer arrangement, typically around 90cm wide. Enormous capacity, and the wide shelves take platters and party food that simply will not go in a 60cm fridge.
Three things to check before you commit:
- Width and door swing. At 90cm you need the floor space and the clearance for two doors to open fully. In a galley kitchen that is often impossible.
- Water and ice. Plumbed models need a mains water connection within reach. Non-plumbed models use a refillable tank, which is simpler to install but needs topping up.
- Delivery access. These are heavy and wide. Measure the narrowest point of the route, not just the kitchen door.
The Smeg FQI60KD four-door in Dark Inox and the Smeg FQ55FXDE two door two drawer at 539 litres are strong options, with the Smeg FQ960 Victoria four-door at 572 litres at the top end. For the fullest integrated alternative, the Liebherr IXCC5155 with BioFresh and NoFrost gives American-style thinking behind a cabinet door.
Reading the split: 70/30, 60/40, 50/50
These numbers are the proportion of fridge to freezer, and the right one depends entirely on how you shop.
- 70/30 — most fridge, least freezer. Suits people who shop fresh several times a week and use the freezer for a few basics.
- 60/40 — the middle ground, and the most popular split in UK homes.
- 50/50 — equal. Suits batch cookers, big monthly shops and households who freeze a lot.
Be honest about which you actually are rather than which you intend to become. A freezer that is permanently full is more annoying, day to day, than a fridge with a spare shelf.
Capacity: gross versus usable
Manufacturers quote gross capacity, which is the raw internal volume. Net or usable capacity is what is left once shelves, drawers and door bins are in — and that is the figure that matters.
As a rough guide, allow around 150 litres of fridge space for two people, plus roughly 50 litres for each additional person. Then think about shape as well as volume: tall bottles, a large turkey and a cake box all need specific clearances that a litre figure does not tell you about.
Frost free, and why it matters
Frost free (sometimes NoFrost) circulates dry air through the freezer so ice never builds up. No defrosting, ever, and no gradual loss of space to a wall of ice. On a large freezer this is worth paying for.
The one thing to know: because the air is drier, unwrapped food dries out faster. Wrap or box things properly and it is a non-issue.
Static freezers do need manual defrosting, usually once or twice a year. They are cheaper and often slightly more efficient, but that job is genuinely tedious.
Fresh-keeping compartments
Most fridges have a salad crisper. Better ones have a proper controlled zone — Liebherr's BioFresh is the best-known — which holds produce just above freezing at controlled humidity. Vegetables, fish and meat keep noticeably longer.
Whether it is worth the premium depends on how you shop. If you buy fresh in bulk once a week and watch things wilt by Thursday, it pays for itself in waste alone. If you shop little and often, it is a nice extra rather than a reason to choose.
Energy ratings, and the label that confuses everyone
The energy label was rescaled in March 2021. The old A+, A++ and A+++ grades were replaced with a plain A to G scale, and the new scale is deliberately much harder — an appliance that would once have been A+++ may now sit at C or D.
So a fridge freezer rated E today is not a poor performer; it is a normal one on a stricter scale. Very few models reach A at all. Compare the annual kWh figure between models rather than reading the letter as a verdict.
Because a fridge freezer runs continuously for a decade or more, a difference in annual consumption compounds into real money in a way it does not with an oven.
The garage question
This one catches people out every winter. Every fridge freezer has a climate class describing the ambient temperature range it is designed to work in. A standard model in an unheated garage or outbuilding can fail in cold weather, because the thermostat sits in the fridge compartment — when the surrounding air is cold enough, the compressor stops running and the freezer section thaws.
If the appliance is going anywhere unheated, check the climate class or look specifically for a garage-safe model. It is a cheap check that prevents a freezer full of ruined food in January.

Before you order
- Measure height, width and depth of the space — and depth including the door and handle.
- Check the door can open fully without hitting a wall, island or another appliance.
- Check which side the door is hinged, and whether it can be reversed.
- Measure the delivery route at its narrowest point.
- Confirm the ventilation gap the manufacturer requires at the back and top.
- For plumbed water or ice, confirm there is a mains supply within reach.
- If it is going in a garage or outbuilding, check the climate class.
- Decide who is taking the old appliance away.
A fridge freezer is the one appliance in the house that never gets switched off. It is worth twenty minutes of measuring and a bit of honesty about how you shop.
