Do you buy a clever all-in-one that microwaves, grills, bakes and air-fries — or will a bulky box just hog your worktop and still bake slower than a real oven? In the United Kingdom, the dilemma is capacity versus footprint, true convection heat versus 200°C limits, and preset convenience versus manual control.

01
Four appliances in one sleek unit that fries, bakes, grills and reheats
Positioned as a space-saving hub for everyday cooking, this 4-in-1 combination model draws positive sentiment from verified owners for doing exactly what it promises. The 25-litre cavity and wide 28.8cm turntable handle family-size plates with ease, while the stainless steel interior wipes down and the included grill rack supports more involved meals. Owners upgrading within the brand describe the button and knob controls plus 10 auto programmes as intuitive once learned, with microwave and grill performance earning praise for reliability and even results. The air fryer function using circulated hot air plus grill heat delivers crisp finishes with little oil, though feedback notes it relies on presets rather than full manual time and temperature control. Ergonomically it is a substantial freestanding unit that needs worktop depth and clearance, and the microwave workflow can feel click-heavy at first. Overall, market feedback frames it as a smart, efficient all-rounder for small kitchens.
- Genuine 4-in-1 versatility covers microwave, grill, convection and air fry in one unit
- Spacious 25L interior handles family-size dinner plates with ease
- Intuitive controls with 10 auto programmes and dedicated defrost setting
- Stainless steel cavity and accessible layout simplify regular cleaning
- Air fryer relies on presets with limited manual time and temperature adjustment
- Bulky freestanding footprint needs ample worktop depth and clearance
- Microwave workflow can feel button-heavy until familiar
02
Big 28L family combi that microwaves, grills and bakes from one countertop footprint
Positioned as a versatile countertop solution for small kitchens avoiding multiple appliances, this 28-litre Samsung combines 900W microwave, grill and convection cooking with touch controls. The glazed ceramic enamel cavity is a real engineering highlight, resisting scratches, rust and odours while wiping clean easily, complemented by eco mode, deodorisation and a turntable on/off option. In daily use, verified owners consistently praise even microwave reheating and a quick, even grill for toast and pizza, plus handy auto-reheat, power defrost and +30 second shortcuts. Fermentation settings for dough and yoghurt add welcome flexibility for family households. Trade-offs reflect its long-running design, with convection capped at 200 degrees often needing longer bake times than a full-size oven, a non-illuminated panel that can be tricky in dim corners, and a plasticky door trim plus large 51.7cm-wide, heavy cabinet that demands solid counter space. Overall sentiment remains strongly positive for reliability and everyday convenience.
- Spacious 28-litre capacity suits family plates, whole chickens and batch reheating
- Even microwave reheating and quick, even grill performance for everyday staples
- Durable glazed ceramic interior wipes clean easily and resists staining and odours
- Useful versatility with 10 auto programmes, power defrost, turntable on/off, Eco mode and fermentation settings
- Convection tops out at 200 degrees and typically needs longer bake times than a full-size oven
- Non-illuminated touch panel can be hard to read in low light or corner placement, and timer setting feels fiddly
03
One compact black combi that microwaves, grills and roasts for the whole family
This freestanding 23-litre combination model is positioned as a compact second-oven solution for family kitchens, pairing a steel cavity with glass turntable and plastic-steel exterior in a classic black finish. Market research shows owners value the straightforward button and dial layout, which feels positive and avoids fussy touch controls, while the sensibly pitched end-of-cycle tone suits open-plan living. Day-to-day utility centres on genuine 3-in-1 flexibility, with microwave, grill and convection modes plus combined settings for roasting, crisping and reheating, supported by ten auto programmes and a dedicated defrost function sized around standard dinner plates. Verified sentiment over more than two hundred ratings leans strongly positive on heating consistency, ease of cleaning and solid door feel. Trade-offs are minor but worth noting, including occasional turntable wander and a cavity light that remains on when airing the oven. Overall it suits buyers wanting one appliance to cover reheating, grilling and light baking without complexity.
- Genuine 3-in-1 versatility for microwave, grill, convection and combined cooking
- Roomy 23L interior handles large plates and whole chicken for family meals
- Tactile dial and button controls praised as simple and reliable in daily use
- Solid steel-cavity build with well finished exterior and easy-clean turntable
- Turntable support can allow plate drift and contact with cavity sides
- Cavity light stays on when door is left open for cooling and venting
04
One premium countertop powerhouse that air fries, roasts, bakes and microwaves with inverter precision.
Positioned as a premium consolidation appliance, the Combi Wave aims to retire a separate microwave, oven and air fryer in one large 32-litre footprint. Market research and verified owner sentiment suggest it largely succeeds when owners embrace the presets, with consistent praise for moist roasts with crisped skins, evenly browned bakes and genuinely crunchy air-fried results thanks to smart power distribution and inverter smoothing. The soft-close door, muted operation modes and child lock add everyday refinement, while the dark stainless finish reads sleek and wipes clean easily. Trade-offs are real. Its size and weight demand dedicated counter space and two-person lifting, the Fast Combi logic automates microwave and grill input without full manual control which frustrates experienced combination-cooking enthusiasts, and overall value depends heavily on using all three functions regularly. Isolated reliability complaints also temper confidence despite a majority of five-star ratings. Best suited to confident cooks wanting consolidation without compromise.
- Genuine 3-in-1 capability across inverter microwave, convection oven and air fryer
- Evenly browned, crispy finishes with moist interiors via smart power distribution
- Thoughtful quiet-use touches including soft-close door, mute and child lock
- Sleek Black Stainless Steel cabinet that looks premium and wipes clean easily
- Large, heavy 32-litre cabinet demands substantial permanent counter space
- Fast Combi mode automates microwave and grill input without full manual override
- Premium-tier value depends on regular multi-mode use, with isolated reports of uneven heating
Buyer Questions and Expert Answers
What is the best overall choice for most homes in the United Kingdom?
The Russell Hobbs 25L 4-in-1 Digital Combination Microwave with Air Fryer Function is the most complete pick for most families because it genuinely covers microwave, grill, convection and air fry in one 25L cavity with 10 auto programmes and defrost. It handles large plates and low-oil crisping without a separate air fryer, though you will need generous worktop depth and clearance.
Can a combination microwave replace a full-size oven?
For reheating, grilling bacon and cheese, roasting a chicken, baking small batches and air frying, yes for everyday use. For large batch baking, tall loaves or Christmas-scale roasting, no — combi cavities are smaller, convection often tops out around 200 degrees on models like the Samsung, and bake times typically run longer than a full-size oven.
What size combination microwave should I buy — 23L, 25L or 28L?
Choose by plate and cookware, not just litres. 23L suits 1-3 people and standard large plates plus a small chicken. 25L is the sweet spot for family dinner plates and air-fry baskets. 28L suits 4+ people, whole chickens and batch reheating. Measure width, depth and door swing, and leave manufacturer-recommended side, top and rear clearance for venting.
Is an air-fryer combi worth it versus a standard 3-in-1 grill-convection model?
If you regularly cook chips, breaded chicken, vegetables and frozen snacks and want less oil without another appliance, the 4-in-1 Russell Hobbs 25L is worth it. If you mainly microwave, grill and bake or reheat, a 3-in-1 like the Samsung 28L or Russell Hobbs 23L is simpler and often easier to clean. Note that many air-fry combis lean on presets with limited manual adjustment.
How do I keep a combination microwave clean and odour-free?
Wipe after grilling or air frying while lukewarm, wash the turntable and rack separately, and steam-clean with a bowl of water and lemon for 5 minutes to loosen grease. Glazed ceramic antibacterial interiors like Samsung’s resist staining best. Avoid metal scourers, do not block vents, and leave the door ajar briefly after cooking to vent moisture.
The Bottom Line
- 🏆 Top Overall Choice: Russell Hobbs 25L 4-in-1 Digital Combination Microwave with Air Fryer Function — best for families wanting microwave, grill, convection and air fry in one spacious unit
- 💰 Best Value: Samsung MC28H5013AS Combination Microwave, 900W, 28 Litre, Silver — best for large households needing extra capacity and a durable easy-clean ceramic interior
- ⭐ Premium Pick: Russell Hobbs Black Microwave 23 Litre 900W Microwave — best for everyday cooks wanting simple, reliable 3-in-1 combi cooking in a worktop-friendly size
For most United Kingdom kitchens in 2026, a combination microwave earns its worktop space when it truly multitasks: fast microwave reheating, even grilling, useful convection baking and — if you want it — low-oil air frying. Choose the 25L 4-in-1 for maximum all-in-one flexibility, the 28L Samsung if capacity and easy cleaning matter most, or the 23L Russell Hobbs if you value simple dial controls and a smaller footprint. Match litres to your plates, check ventilation space, and accept that even the best combi bakes a little slower than a full oven.
