How to measure the space properly
Start with the physical space before looking at style or features. AO’s buying guidance says to check height, width, depth and door clearance, and to think about ventilation and delivery access as well as the opening itself. That matters even more for larger American-style models like the Hisense KitchenFit RQ768N4GVE at £1,301 and the two PureFlat Infinite models at £999, because a fridge freezer that looks suitable on paper can still be awkward if the doorway, hallway or cabinet gap is tight.
Choosing capacity by household size
Capacity is measured in litres, so the most useful question is not “how big is it?” but “how much food does this household actually store?” AO’s guidance links the fridge section to fresh-food buying habits and the freezer section to how often you batch cook or stock up, which makes split ratio just as important as headline size. The three Hisense examples all sit in the same broad family, so the real comparison is whether the layout gives you enough fridge space for weekly produce or enough freezer space for bulk buying.
Freestanding vs integrated fit
Integrated models need extra planning because they must fit the housing unit as well as the available kitchen space, so the cabinet opening matters as much as the appliance dimensions. Freestanding models are usually simpler to place and replace, while American-style fridge freezers add another layer of fit checks because side-by-side or multi-door layouts change how doors open and how you use the shelves. If your kitchen is fitted, measure carefully against the housing unit first; if it is open-plan or flexible, the wider PureFlat Infinite and KitchenFit styles may suit different storage habits.
Energy use and running costs
For shoppers comparing similar fridge freezers, energy rating, frost-free design and size are the main value clues to check on the retailer page. A larger model such as the £1,301 Hisense KitchenFit RQ768N4GVE may suit a bigger household, but it is worth comparing it with the £999 PureFlat Infinite pair to see whether the extra spend is buying a layout or feature set that genuinely helps daily use. Because no independent performance data is included here, treat any running-cost discussion as a brief to verify the current energy rating and compare it with the appliance size before you buy.
What the research points to
This is a shortlist guide, not a winner list, because the strongest evidence is about fit, capacity and review volume rather than independent performance results. All three Hisense examples carry a 4.9 average rating, but the KitchenFit RQ768N4GVE has up to 30 reviews while the two PureFlat Infinite models have up to 3,258, so the larger review pool gives the £999 models a firmer public rating base. The evidence also suggests the smartest comparison is layout and household need, especially since live retailer details were unavailable and should be rechecked for dimensions, energy rating, delivery and stock.
How to choose between the shortlist
If you want the clearest review-volume signal, the two PureFlat Infinite models at £999 are easier to read because both share the same 4.9 average with up to 3,258 reviews. If your priority is a tighter-fit or more premium-feeling kitchen choice, the KitchenFit RQ768N4GVE at £1,301 may be the one to inspect first, but its smaller review sample of up to 30 means the rating should be treated more cautiously. The WiFi-connected PureFlat Infinite RQ758N4SWSE is best treated as a feature-led choice rather than a price-led one, since it shares the same £999 starting price as the non-WiFi model.

Firmness questions
How much space do I need around a fridge freezer?
Check the appliance’s height, width and depth first, then leave extra room for door opening, ventilation and delivery access. GE’s guidance also highlights clearance at the back and top, plus checking hallways and doorways before delivery.
What fridge freezer capacity do I need for a couple, family or bulk shopper?
Capacity is measured in litres, so the right size depends on how much shopping you keep at home. Couples may be comfortable with a smaller layout, while families and bulk shoppers usually need more litres and a freezer split that matches how often they buy frozen food.
Should I choose an integrated, freestanding or American-style fridge freezer?
Choose integrated if you want the appliance to sit behind cabinetry, but check the housing-unit fit carefully. Freestanding models are easier to place, while American-style side-by-side or multi-door designs give more storage planning options but need more space.
Does a higher price always mean the better fridge freezer choice?
Not necessarily. In this shortlist, the £1,301 KitchenFit model is pricier than the £999 PureFlat Infinite pair, but the better choice depends on fit, capacity, layout and whether the extra spend gives you a useful design difference.
Are WiFi-connected fridge freezer features actually worth paying attention to?
Only if they suit how you use the kitchen. The WiFi-connected PureFlat Infinite RQ758N4SWSE shares the same £999 price as the non-WiFi version, so it is mainly a feature comparison, not a price comparison.
