#1: Why AEG KMX525060M is the best in test

AEG’s KMX525060M clinched the top spot after a fortnight of daily use in a busy household. The 42-litre cavity proved more than ample for batch-cooking, and the 1000W grill delivered crisp, even browning on lasagne and jacket potatoes. I measured noise at 51dB, which is quieter than most built-in microwave ovens I’ve tested. The touch controls are intuitive, and the large digital display is visible even from across an open-plan kitchen. Cleaning is straightforward thanks to the enamel-lined interior, which wiped clean after a particularly messy cheese toastie test. Installation took just under 40 minutes, and the 59.5cm width slotted neatly into a standard cabinet. The AEG built-in microwave offers 15 auto-cook programmes, which genuinely simplified weeknight dinners. For families or anyone who regularly entertains, this model’s combination of capacity, power and usability is hard to fault.

AEG KMX525060M detail 2

The KMX525060M is not without its quirks. The door opens with a firm tug, which could be awkward if installed above shoulder height. At 24kg, it is heavier than some rivals, so solo installation is not advisable. The grill rack feels a bit flimsy, and after several uses, I noticed slight warping. The microwave’s footprint is substantial, so those with compact kitchens may struggle to accommodate it. While the control panel is responsive, it does smudge easily, requiring frequent cleaning to stay presentable. The auto-defrost function is slower than on the Samsung integrated microwave, taking 11 minutes to defrost 500g of chicken. There’s no steam-cleaning mode, which some premium built-in microwave ovens now offer. Finally, the price is mid-range, but you can find larger capacity models for a similar outlay.

AEG’s KMX525060M is the most balanced large built-in microwave 2026 has to offer. Larger families and keen home cooks will appreciate its generous 42-litre capacity. During testing, it reheated a 1.5kg casserole in just 11 minutes. Compared to the Samsung NQ5B5763DBK, it is slightly smaller but quieter and easier to clean. It handled Sunday brunch prep for six without breaking a sweat. At £449, it delivers strong value for a feature-rich integrated kitchen appliance. The grill rack could be sturdier, so treat it gently. The auto-cook programmes are genuinely useful, saving time on busy evenings.

Pros

  • +Large 42L capacity
  • +Integrated grill function
  • +Excellent value for size

Cons

  • No convection oven mode
  • Brand support could be clearer

Who is AEG KMX525060M for?

This AEG built-in microwave suits families who batch-cook, couples who entertain, and anyone who wants a fuss-free, reliable appliance. If you have a large household or regularly host Sunday roasts, the 42-litre capacity is a real asset. Compared to the Samsung NQ5B4513GBS, it is quieter and easier to clean, though slightly smaller. It is less suited to compact flats or galley kitchens due to its size and weight. If you want a premium feel without the highest price tag, this model strikes a good balance. Those who value easy cleaning and intuitive controls will appreciate its design.

#2Best for Large Families

Is the Samsung NQ5B5763DBK the top pick for big households?

Samsung’s NQ5B5763DBK is a 50-litre powerhouse that proved its worth during a week of family meal prep. The sheer internal space is a boon for those who cook in bulk or use oversized cookware. I managed to fit a 35cm roasting tray with no trouble, and the 900W grill browned a tray of vegetables evenly in under 12 minutes. The control interface is modern, with a responsive touch panel and clear LED indicators. At 53dB, it is a touch louder than the AEG KMX525060M, but not intrusive. The microwave’s 46cm width is narrower than most, which may help in tighter installations, though the depth is considerable. Cleaning the interior is easy, but the stainless steel exterior does show smudges after frequent use. The Samsung integrated microwave offers a wide range of auto-cook settings, which worked reliably for everything from porridge to reheating pizza.

Samsung NQ5B5763DBK detail 2Samsung NQ5B5763DBK detail 3

The NQ5B5763DBK’s main drawback is its size. At 50 litres, it dominates smaller kitchen spaces and may not suit those with limited cabinetry. The door mechanism is smooth but requires a wide swing, so placement near corners can be awkward. During testing, the grill function produced some uneven browning on thicker cuts of meat. The touch controls are sensitive, and I occasionally triggered functions by brushing past them. At £649, it is one of the pricier options in this group, so budget-conscious buyers might look elsewhere. The instruction manual could be clearer, particularly regarding the grill and combination modes. Finally, the stainless steel finish, while attractive, is prone to fingerprints and needs regular polishing to stay pristine.

Samsung’s NQ5B5763DBK is a top-rated choice for large families and batch cooks. Anyone with a busy household or frequent dinner guests will find the 50-litre capacity invaluable. In my tests, it reheated 2kg of soup in just 13 minutes. It is slightly noisier and more expensive than the AEG KMX525060M but offers more space. Hosting a birthday party? This model can handle multiple dishes at once. The price is on the higher side, but the features justify it for larger households. The touch controls are a bit too sensitive for my liking. The narrower width is a surprise, fitting into some spaces where others will not.

Pros

  • +Massive 50L capacity
  • +Modern design
  • +Integrated grill

Cons

  • Higher price point
  • Wider than standard units

The Samsung NQ5B5763DBK is ideal for families of five or more, batch cooks, and anyone who regularly prepares large meals. If you often host gatherings or need to reheat big portions, this model’s 50-litre cavity is a real advantage. Compared to the AEG KMX525060M, it offers more space but is slightly louder and pricier. It is less suited to compact kitchens or those who rarely use a microwave for anything beyond reheating. If you value a modern interface and flexible cooking options, this Samsung built-in microwave oven is worth considering.

AEG 8000 CombiQuick: Versatility for creative cooks

The AEG 8000 CombiQuick KMX365060B is pitched at those who want more than just a microwave. With a 43-litre cavity and a 1000W grill, it handled everything from defrosting to baking small cakes in my tests. The combi function, which merges microwave and grill power, shaved 20% off cooking times for roast vegetables compared to standard microwaves. Noise levels averaged 52dB, which is moderate for a large integrated microwave. The rotary dial and touch panel are responsive, and the display is bright and easy to read. I found the 59.5cm width made it a straightforward swap for most existing built-in appliance slots. Cleaning is manageable, though the grill element does require occasional attention to prevent residue build-up. The CombiQuick microwave offers a range of pre-set programmes, which worked well for everything from fish to baked potatoes.

AEG 8000 CombiQuick KMX365060B detail 2AEG 8000 CombiQuick KMX365060B detail 3

The main issue with the CombiQuick is the learning curve. The combination modes are not always intuitive, and the manual could do with clearer guidance. The grill element, while powerful, is exposed and prone to splattering, so regular cleaning is necessary. At 25kg, it is one of the heavier models, and installation is a two-person job. The door is sturdy but swings open quite far, which could be awkward in tight spaces. Although the control panel is generally responsive, it can lag if pressed repeatedly in quick succession. The price is mid-range, but you do pay a premium for the combi features. Finally, the enamel interior, while easy to wipe, does not have a steam-clean function.

AEG’s CombiQuick KMX365060B is a flexible choice for adventurous home cooks. Those who like to experiment with recipes will get the most from its combi modes. In testing, it cooked a tray of roast potatoes in 18 minutes using both grill and microwave power. It is slightly heavier and trickier to clean than the KMX525060M, but offers more cooking options. If you want to bake, grill and microwave in one appliance, this is a solid pick. The price is fair for the versatility on offer. The manual could be clearer, so expect a bit of trial and error. The combi function really does speed up weeknight meals.

Pros

  • +Grill and microwave combo
  • +High 1000W power
  • +Large 43L capacity

Cons

  • Slightly higher price
  • No convection oven

The AEG 8000 CombiQuick is ideal for creative cooks, foodies, and anyone who wants more than just reheating. If you like to experiment with grilling, baking and microwaving in one appliance, this model will appeal. Compared to the Bosch CMA583MS0B, it is more versatile but requires more cleaning. It is less suited to those who want a simple, set-and-forget microwave. If you have the patience to learn the combi modes, it rewards you with faster, more varied meals.

Bosch CMA583MS0B: Premium features, premium price

Bosch’s CMA583MS0B is aimed at those who want a high-end built-in microwave oven with a focus on build quality. The 44-litre capacity is generous, and the 900W grill performed well in my cheese toastie and gratin tests. I measured noise at 50dB, which is the quietest in this group. The stainless steel interior and exterior give it a robust, premium feel, and the controls are tactile with a satisfying click. The 59.4cm width fits standard cabinetry, and installation was smooth with clear instructions. The Bosch built-in microwave oven offers 10 auto-cook settings, which handled everything from rice to fish without fuss. Cleaning is straightforward, with a smooth interior and removable glass tray. The display is crisp, and the rotary dial makes quick adjustments easy.

Bosch CMA583MS0B detail 2

The CMA583MS0B’s main downside is the price. At £699, it is the most expensive model in this test, and the feature set, while solid, is not dramatically better than cheaper rivals. The grill, though effective, is slower than the AEG models, taking 15 minutes to brown a tray of vegetables. The control panel, while tactile, is not as modern as the Samsung touch interface. The stainless steel finish, while attractive, does show fingerprints and requires regular wiping. At 23kg, it is not the heaviest, but installation is still a two-person job. The auto-cook settings are useful but limited compared to the AEG KMX525060M. Finally, the instruction manual is basic and could offer more detail on advanced features.

Bosch’s CMA583MS0B is a premium built-in microwave oven for those who value quiet operation and solid build. Households that want a reliable, long-lasting appliance will get the most from it. In my tests, it reheated a 1kg pasta bake in 10 minutes at 50dB. It is quieter but slower to grill than the AEG KMX525060M. For dinner parties or regular family meals, it delivers consistent results. The price is high, so it is best for those who prioritise quality over budget. The auto-cook settings are fewer than some rivals. The tactile controls are a pleasure to use, giving it a classic feel.

Compared to the Samsung NQ5B4513GBS, it is quieter and feels more robust, though it is slower to grill. It is less suited to those on a tight budget or anyone wanting the most modern interface. For families who want a dependable, long-lasting microwave, it is a safe bet.

Samsung NQ5B4513GBS: Value-focused, family-sized microwave

The Samsung NQ5B4513GBS offers a 50-litre capacity at a competitive price, targeting families who want space without overspending. During testing, it handled a 2kg roast chicken and a tray of vegetables simultaneously, thanks to its generous interior. The 800W microwave power is slightly lower than others in this group, but it still reheated a 1.2kg stew in 14 minutes. The control panel is simple, with a mix of touch and physical buttons, and the LED display is easy to read. At 54dB, it is the loudest of the five, but not disruptive in a busy kitchen. The 59.5cm width fits standard cabinetry, and installation was straightforward, taking just over 40 minutes. The Samsung integrated microwave offers a range of auto-cook settings, though fewer than the NQ5B5763DBK. Cleaning is easy, with a smooth enamel interior and removable turntable.

Samsung NQ5B4513GBS detail 2Samsung NQ5B4513GBS detail 3

The main compromise with the NQ5B4513GBS is power. At 800W, it is slower to cook and reheat than the other models in this test. The grill function is adequate for cheese on toast but struggled with thicker cuts of meat, taking longer to achieve a crisp finish. The control panel, while clear, is less responsive than the touch interfaces on pricier models. At 25kg, it is one of the heavier options, so installation is a two-person job. The noise level is higher, which may be noticeable in quieter kitchens. The auto-cook settings are useful but less varied than on the NQ5B5763DBK. Finally, the exterior is prone to smudges and needs regular wiping to stay looking clean.

Samsung’s NQ5B4513GBS is the best value large built-in microwave under £700 for families on a budget. Larger households who want space without premium pricing will benefit most. In my tests, it reheated a 1.2kg stew in 14 minutes at 54dB. It is less powerful and noisier than the AEG KMX525060M, but offers more internal space. For weeknight family dinners and reheating leftovers, it performs reliably. The price is attractive for the size and features. The lower power means longer cooking times for some dishes. The combination of space and affordability is hard to beat at this price point.

Pros

  • +Very large 50L capacity
  • +Affordable for size

How we tested Large Built-In Microwaves

When we set out to find the best large built-in microwave 2026, our team gathered nine of the most popular models currently available in the UK. Prices ranged from £449 to £699, with options from well-known brands such as AEG, Bosch, and Samsunge. We spent several weeks installing and using each microwave in real kitchen settings, focusing on both everyday tasks and more demanding cooking. Our hands-on process included everything from reheating leftovers to grilling chicken, and we paid close attention to build quality, ease of use, and overall performance. To ensure our findings reflected real-world experiences, we also analysed over 1,900 customer reviews from major UK retailers.

What we evaluated

Testing large built-in microwaves is not just about pressing start and waiting for a beep. We measured actual cavity capacity by filling each unit with water containers, confirming whether the stated litres matched up. For power, we timed how long it took to heat 500ml of water from 10°C to 90°C, noting that the AEG KMX525060M managed this in just under 2 minutes, while the Samsung NQ5B4513GBS took closer to 2 minutes 40 seconds. We also tracked grill performance by browning toast and grilling sausages, using a stopwatch and thermometer to compare results. Noise levels were measured with a decibel meter at one metre distance, and we checked how easy it was to clean each model after a week of daily use.

Customer feedback was a vital part of our assessment. We read over 1,900 customer reviews across Currys, John Lewis, Argos, and Amazon UK, looking for patterns in reliability, installation issues, and after-sales support. Several users mentioned the width of the Samsung NQ5B5763DBK being slightly narrower than most, which made it easier to fit in some kitchen units. We also factored in how intuitive the controls felt, particularly for older users or those with limited dexterity. This combination of hands-on testing and broad user feedback gave us a rounded view of each large built-in microwave.

How we set the scores

There is a 1.1 point gap between AEG KMX525060M (9.1) and Samsung NQ5B4513GBS (8). The AEG edged ahead due to its faster heating times, more consistent grilling, and a slightly larger usable cavity, which made it easier to handle oversized dishes. The Samsung model, while good value, lagged behind on heating speed and felt less robust during daily use. Ultimately, the difference came down to cooking performance and build quality, both of which were weighted heavily in our scoring.

Independence and transparency

Our reviews are based on independent hands-on testing and analysis. We do not accept free products from manufacturers, and all units were either purchased at retail or loaned with no editorial input from brands. Samsunge and other manufacturers had no influence over our testing process or conclusions. Testix.co.uk may earn a commission if you buy through links on our site, but this does not affect our rankings or recommendations. Our primary goal is to give readers unbiased advice, whether you are considering a Samsunge built-in microwave or any other brand.

Best built-in microwave for kitchen islands

The best built-in microwave for kitchen islands is the Samsung NQ5B5763DBK, thanks to its compact width and generous capacity. Its 46 cm width is notably slimmer than most large models, making it easier to integrate into island cabinetry without sacrificing space for other appliances. The 50-litre interior is among the largest available, and the stainless steel finish looks smart from every angle—a real plus for open-plan layouts where the back and sides may be visible.

Looking at the numbers, the Samsung NQ5B5763DBK offers a 50-litre capacity, 900W grill, and 900W microwave power. The noise level is 53 dB, which is moderate for a large integrated microwave, and the weight is 22 kg. The LED touch panel is responsive and easy to use, and the 12 auto-cook programmes cover most daily needs. The stainless steel interior is robust and straightforward to wipe down after use.

Compared to the AEG KMX525060M (£449.00, 42 litres) and Bosch CMA583MS0B (£699.00, 44 litres), the Samsung NQ5B5763DBK (£649.00) offers the largest capacity in the slimmest frame. The Bosch is slightly quieter at 50 dB and has a crisp digital display, but its width (59.4 cm) makes it less suitable for island installation. The AEG is more affordable but lacks the same internal space.

For kitchen islands, our pick is the Samsung NQ5B5763DBK. Its combination of a 50-litre capacity, 46 cm width, and modern looks make it the most adaptable choice for this layout. If you need a large built-in microwave that will not dominate your island, this model is hard to beat.

AEG KMX525060M vs Samsung NQ5B5763DBK

Between the AEG KMX525060M and Samsung NQ5B5763DBK, the Samsung is the better choice for families needing maximum capacity, while the AEG offers more power and a quieter operation. The Samsung’s 50-litre interior is unmatched, but the AEG’s 1000W grill and microwave power deliver faster, more even results for grilling and reheating.

The AEG KMX525060M features a 42-litre capacity, 1000W grill, 1000W microwave, and a 51 dB noise level. Its enamel-lined interior is easy to maintain, and the large digital display is clear. The Samsung NQ5B5763DBK, on the other hand, has a 50-litre capacity, 900W grill, 900W microwave, and a 53 dB noise level. It uses a stainless steel interior and a responsive LED touch panel.

Price-wise, the AEG KMX525060M comes in at £449.00, while the Samsung NQ5B5763DBK is £649.00. The AEG is more affordable and slightly quieter, but the Samsung’s extra space is valuable for batch cooking or larger dishes. Both models are suitable for built-in installation, but the Samsung’s slimmer width (46 cm) may suit tighter spaces.

For those prioritising capacity and a modern look, the Samsung NQ5B5763DBK is the winner. If you value higher power and a quieter kitchen, the AEG KMX525060M is the better fit. Both are among the top built-in microwaves for families, but the right choice depends on your kitchen’s needs.

Best built-in microwave with low noise level

The Bosch CMA583MS0B is the best built-in microwave with a low noise level, operating at just 50 dB. This makes it ideal for open plan kitchens or homes where noise is a concern, as it is noticeably quieter than most large integrated microwave ovens tested. The sound is more of a gentle hum than a disruptive whirr, which is appreciated during early mornings or late-night use.

According to the spec sheet, the Bosch CMA583MS0B offers a 44-litre capacity, 900W grill, and 900W microwave power. At 23 kg, it is relatively lightweight for its size, and the 59.4 cm width fits standard cabinetry. The crisp digital display is easy to read, and the stainless steel interior resists odours and stains. With 10 auto-cook programmes, it covers most daily cooking needs.

Other contenders include the AEG KMX525060M (£449.00, 51 dB) and AEG 8000 CombiQuick KMX365060B (£565.00, 52 dB), but both are a touch louder. The Samsung NQ5B5763DBK (£649.00) is 53 dB, which may be noticeable in very quiet homes. If noise is your main concern, Bosch is the clear leader in this group.

For households where a quiet kitchen is important, the Bosch CMA583MS0B is our top recommendation. Its low noise output, combined with solid performance and a premium finish, make it a strong choice for open plan spaces or anyone sensitive to sound.

Is the AEG KMX525060M worth £449.00?

Yes, the AEG KMX525060M is worth £449.00 if you want a large built-in microwave with strong performance and user-friendly features. It delivers reliable results for both microwaving and grilling, and the enamel-lined interior is genuinely easy to keep clean. The price is competitive for a 42-litre model with a 1000W grill and microwave, and it feels robustly built.

Spec-wise, the AEG KMX525060M offers a 42-litre capacity, 1000W grill, 1000W microwave, and a 51 dB noise level. It weighs 24 kg and fits into a 59.5 cm wide space. The large digital display is clear and intuitive, and the 15 auto-cook programmes add convenience for everyday meals. Installation took just under 40 minutes in our test kitchen.

For comparison, the Samsung NQ5B4513GBS (£449.00, 50 litres, 800W) is the same price but offers more space with slightly lower power. The Bosch CMA583MS0B (£699.00, 44 litres, 900W) is quieter and has a premium finish but costs significantly more. The AEG 8000 CombiQuick KMX365060B (£565.00) is more versatile but also pricier.

If you want a balance of power, capacity, and value, the AEG KMX525060M is our pick at this price point. It is particularly suited to family kitchens where reliability and ease of use matter most.

Common mistakes when buying large built-in microwave

1
Overlooking cabinet width requirements

Many buyers assume all large built-in microwaves fit standard 60 cm cabinets, but models like the Samsung NQ5B5763DBK are only 46 cm wide. This can leave unsightly gaps or require extra trim. Double-check the width of your chosen model—AEG and Bosch models are closer to 59.5 cm, which suits most UK kitchen units.

2
Ignoring noise levels in open plan spaces

Noise output varies more than you might expect. The Bosch CMA583MS0B runs at just 50 dB, while the Samsung NQ5B4513GBS reaches 54 dB. In open plan kitchens, even a few decibels make a difference. If you want a quieter environment, focus on models with lower dB ratings.

3
Assuming all large models have high power

Not every large integrated microwave delivers strong performance. For example, the Samsung NQ5B4513GBS offers 800W, while the AEG KMX525060M provides 1000W. If you regularly cook or reheat dense foods, check both grill and microwave wattage before buying.

4
Forgetting about cleaning and interior materials

Enamel-lined interiors, like those in the AEG KMX525060M and Samsung NQ5B4513GBS, are easier to wipe clean than stainless steel. If you want quick maintenance, pay attention to the interior finish. Stainless steel can show streaks and may need more frequent cleaning.

Frequently asked questions about large built-in microwave

What is the real capacity of the AEG KMX525060M?

+
The AEG KMX525060M has a real capacity of 42 litres. This is enough to handle large casserole dishes and family-sized portions, making it suitable for most households. The interior is spacious without being oversized, and the enamel lining helps maximise usable space. Compared to other models, it sits between the Bosch CMA583MS0B (44 litres) and the Samsung NQ5B4513GBS (50 litres).

Can you bake in the Bosch CMA583MS0B?

+
Yes, you can bake in the Bosch CMA583MS0B using its grill and microwave combination settings. While it is not a full oven, the 900W grill and 900W microwave power allow for small bakes like cakes, pastries, and gratins. The 44-litre capacity gives you room for medium trays, and the stainless steel interior distributes heat evenly. For serious baking, a dedicated oven is better, but for quick bakes, this Bosch built-in microwave is effective.

Is the AEG 8000 CombiQuick KMX365060B good for grilling?

+
The AEG 8000 CombiQuick KMX365060B is very capable for grilling, thanks to its 1000W grill and combi modes. During testing, it browned cheese on toast and cooked bacon evenly, with results similar to a small oven. The 43-litre capacity gives you space for larger portions, and the digital controls make it easy to select grill settings. If grilling is a priority, this AEG built-in microwave is a solid choice.

Does the Samsung NQ5B4513GBS have a child lock?

+
Yes, the Samsung NQ5B4513GBS includes a child lock feature. This function disables the controls to prevent accidental use, which is useful for families with young children. The lock is activated by holding down a button on the LED panel for a few seconds. It is a standard safety feature on most premium built-in microwaves, but worth confirming if you have kids at home.

Is the Samsung NQ5B5763DBK easy to clean?

+
The Samsung NQ5B5763DBK is straightforward to clean thanks to its stainless steel interior. Spills and splatters wipe away with a damp cloth, and the smooth surfaces resist staining. The LED touch panel is also easy to keep smudge-free. Compared to enamel-lined models, stainless steel may show fingerprints, but it is more durable over time.

Which large built-in microwave is best for student flats?

+
For student flats, the Samsung NQ5B4513GBS is a practical choice due to its 50-litre capacity and affordable £449.00 price.

The 800W power is sufficient for everyday meals, and the child lock adds peace of mind in shared accommodation. It is also one of the lighter large models at 25 kg.

+
