What size fridge freezer do you need?
Start with the space, not the sticker price. AO’s measurement guidance says to check height, width, depth and door clearance before you shortlist anything, because a model that does not fit the kitchen is the wrong buy at any budget. For this guide, the range runs from the Hisense KitchenFit RB3K330SAFC 186cm 60/40 Total No Frost Fridge Freezer at £699 up to the Hisense KitchenFit RQ768N4GVE Total No Frost Multi-door American Fridge Freezer at £1,699, with the PureFlat Infinite RQ758N4SWSE at £1,199 in the middle.
Freestanding vs built-in: which suits your kitchen?
The practical choice is about how the appliance sits in the room, not just its brand or finish. AO presents integrated fridge freezers as a space-saving option that sits behind cupboard doors for a streamlined look, while freestanding models are easier to place and replace if your kitchen layout is more flexible. In this shortlist, the KitchenFit range points shoppers toward a fitted look, while the PureFlat Infinite RQ758N4SWSE adds a different multi-door, American-style approach that needs the same careful space planning.
Frost free, total no frost and other cooling features
Frost-free and total no frost features are worth viewing as convenience choices, not buzzwords. They reduce the need for manual defrosting, which can suit busy households that want lower-maintenance ownership, but you should still weigh that against the price gap between the £699 KitchenFit RB3K330SAFC and the £1,699 KitchenFit RQ768N4GVE. AO also highlights flexible cooling zones as useful for some shoppers, so check whether a feature genuinely matches how you store fresh and frozen food day to day.
When smart features are worth paying for
Smart features only matter if you will actually use them. The Hisense PureFlat Infinite RQ758N4SWSE is the clearest example here because it is described as WiFi connected, which may suit shoppers who want app control, alerts or extra convenience around the kitchen routine. If you do not need connected features, it is reasonable to treat them as optional and focus more heavily on fit, capacity and the current price instead of paying extra for a feature set you may barely notice.
How to balance price, running costs and storage needs
AO treats energy efficiency as one of the key comparison points for fridge freezers, so shoppers should look beyond headline capacity and think about day-to-day running costs as part of value. In this trio, the prices create a clear ladder: £699 for the Hisense KitchenFit RB3K330SAFC, £1,199 for the WiFi-connected PureFlat Infinite RQ758N4SWSE, and £1,699 for the KitchenFit RQ768N4GVE. The best comparison is not which is biggest or fanciest, but which one gives you enough storage, the right installation type and the features you will actually use.
What the wider research shows
The most dependable shopping advice here is consistent across AO’s guidance: compare size, layout or split type, features and installation fit before you compare extras. That matters because the live product pages were not fully accessible during checking, so the safest reading is to use the shortlist as a comparison guide rather than a definitive ranking. Review evidence is uneven too: the PureFlat Infinite RQ758N4SWSE has a 4.9 average rating from 3,294 reviews, while the KitchenFit RQ768N4GVE and KitchenFit RB3K330SAFC have much thinner review counts at 36 and 28, so those ratings should be treated as shopper confidence signals rather than proof of performance.
How to turn the advice into a shortlist
The cleanest way to compare this trio is by budget and use case, not by brand loyalty, because all three examples are Hisense fridge freezers. The £699 KitchenFit RB3K330SAFC is the entry point, the £1,199 PureFlat Infinite RQ758N4SWSE adds WiFi-connected convenience, and the £1,699 KitchenFit RQ768N4GVE sits at the premium end of the set. Before buying, check the live AO page for exact dimensions, capacity, installation type, delivery options and current price, since the product details available at the time of checking were limited.

Firmness questions
How do I measure for a fridge freezer before buying?
Measure the space carefully in three directions: height, width and depth. Then allow extra room for door swing, ventilation and the way the appliance will be moved into place, because clearance can matter as much as the headline size.
Is integrated or freestanding better for my kitchen layout?
Integrated suits a fitted kitchen and gives a more streamlined look behind cupboard doors, while freestanding is usually easier to place, swap and live with if your layout may change. The right choice depends on how permanent the kitchen plan is.
How should I judge review counts and ratings on AO?
Treat ratings and review counts as shopper reputation signals, not independent performance evidence. In this shortlist, the PureFlat Infinite RQ758N4SWSE stands out with 3,294 reviews, while the other two models have far smaller counts, so the signals are not equally strong.
