Best Microwaves UK (2026)
A microwave's real test is how evenly it heats and defrosts, not just its headline wattage. This guide compares microwaves tested by Trusted Reviews using a thermal camera to check even heating, alongside real tasks like defrosting bread and cooking jacket potatoes.
We have not hands-on tested these products. Our picks are based on published independent tests and reviews, listed at the bottom of this page. How we pick.
Our top pick
Sage Combi Wave 3 in 1
Best overall
Trusted Reviews found this performed admirably across nearly every function, cooking a jacket potato in under seven minutes and a 1.6kg roast chicken using combined microwave, oven and grill modes. Air fry mode gave evenly browned, crispy chips with a helpful stir reminder halfway through, though it's large and expensive.
- Easy to use
- Genuinely versatile (air fryer, oven, grill, microwave)
- Powerful and fast cooking

Best large
Samsung MS32DG4504ATE3 Large Capacity Solo Microwave
Trusted Reviews was seriously impressed by consistent results across both conventional and difficult tasks, defrosting chicken in around 10 minutes and salmon in just 7.5. Bacon reached piping hot in 45 seconds, though the huge dimensions demand serious counter space and it only offers basic functionality for the price.
- Capacity
- 32L
- Dimensions
- 517 x 423 x 295mm
- Price guide
- £130
Pros
- Modern, seamless design
- Consistent cooking results
- Extra-large capacity
Cons
- Only basic functionality
- Large dimensions need generous counter space
Best combi oven
Panasonic NN-CS89LBBPQ Combination Microwave Oven
The most generous oven space Trusted Reviews has seen in a microwave, with three tray slots for cooking multiple items and auto programmes handling up to 2kg of meat. A humidity-sensing combi programme delivered a jacket potato with crispy skin and fluffy centre, though the touch controls aren't very intuitive and results can be uneven.
- Design
- Flatbed with drop-down door
- Cleaning
- Self-cleaning steam function
- Price guide
- £599
Pros
- Versatile auto programmes for defrosting, steaming, grilling, roasting
- Spacious flatbed design
- Self-cleaning function
Cons
- Expensive
- Not very intuitive controls
- Some uneven cooking results
Best for automated programmes
Samsung Easy View Convection Oven with HotBlast Technology MC28M6075CS
Samsung's Sensor cooking mode measures gasses released from food to stop cooking at the optimal point, giving Trusted Reviews a jacket potato that was fluffy inside and cooked through. Automatic defrost programmes worked well too, though HotBlast convection results don't quite match a dedicated air fryer for crispiness.
- Power
- 900W
- Capacity
- 28L
- Modes
- Sensor cooking, HotBlast convection, auto defrost
Pros
- Very easy to use
- Automated cooking programmes work brilliantly
- Can do many jobs a full oven can
Cons
- Needs space for all the accessories
Best flatbed
Caso MCG 25 Ceramic Chef Microwave
A flatbed design that Trusted Reviews found gave even heating with no cold spots on basic tasks, and worked well combining grill and microwave modes together. The convection oven setting performed admirably too, though the interface takes getting used to and the standalone grill wasn't particularly even.
- Capacity
- 25L
- Design
- Flatbed
- Modes
- Grill, convection oven, combination
Pros
- Flatbed design fits larger dishes
- Excellent value
- Wide range of cooking options
Cons
- Fiddly interface to learn
- Grill wasn't very even
Best budget flatbed
Caso Design MG 20 Ecostyle Ceramic Microwave & Grill
A rare flatbed microwave for just over £100, with no turntable meaning more usable internal space for rectangular dishes and easier cleaning. Trusted Reviews found microwave performance convincing, with rice heating evenly and a fluffy baked potato centre, though there are no automated programmes and the grill runs hot enough to catch food at the edges.
- Capacity
- 20L
- Design
- Flatbed
- Power levels
- 5
- Price guide
- ~£100
Pros
- Great value
- Flatbed design maximises usable space
- Cooks well on standard microwave mode
Cons
- Small grill
- No automated programmes, manual timing needed
- Manual could be clearer
Best budget
Morphy Richards Cassini 20L Digital Microwave
Trusted Reviews picked this for small households wanting something straightforward and good-looking, available in green, black or blue with a dimpled finish that resists fingerprints. Digital controls and a useful defrost mode cover the essentials well, though you can't add extra cooking time partway through a cycle.
- Capacity
- 20L
- Controls
- Digital
- Price guide
- ~£114
Pros
- Looks great
- Digital controls
- Useful defrost mode
Cons
- Can't add cooking time mid-cycle
Buying guide
Solo, grill or combi microwave?
A solo microwave just heats and defrosts. A grill microwave adds browning and crisping via a heating element. A combi microwave, like the Sage Combi Wave or Panasonic here, adds a convection oven mode too, letting it roast and bake much like a full oven, at a higher price.
Does a flatbed microwave actually cook better than a turntable one?
Not necessarily better, but flatbed microwaves like the Caso models here offer more usable internal space since there's no rotating plate to work around, making it easier to fit rectangular or oversized dishes. Even heating still depends on the specific model's design, not just the absence of a turntable.
What capacity do I need?
A 20L microwave suits one or two people and everyday reheating. Larger households, or anyone wanting to cook bigger dishes or use a full dinner plate comfortably, should look at 28-32L models like the Samsung or Sage here, but check they'll actually fit your counter space first.
Are automated sensor cooking programmes worth it?
Automated programmes, like Samsung's Sensor cooking here, remove the guesswork of choosing power and time for specific foods, which is genuinely useful for jacket potatoes or defrosting. They add cost though, so they're most worth it if you regularly cook a variety of different foods rather than just reheating the same few meals.
