A grill microwave promises the best of both worlds — fast reheating plus proper browning — but in UK kitchens space, power and ease of cleaning force real trade-offs. Do you prioritise a compact flatbed that wipes clean, a balanced all-rounder with true crisping modes, or a large family cavity that can handle batch plates? Get the balance wrong and you end up with soggy toasties, cold spots, or a machine that dominates the worktop.

01
Roomy grill power and crispy combo cooking in a sleek mirror finish
This 23 litre Toshiba pairs a black mirrored glass door with stainless steel cavity detailing to deliver a countertop presence that owners praise for looking compact yet feeling roomy inside. The 900W microwave combined with 1000W grill and two combination modes covers reheating, defrosting and browning in one footprint, supported by 11 power levels, 20 auto menus and weight or time Chef Defrost with turn reminders. Daily ergonomics stand out in verified sentiment, with one-touch express cooking from one to six minutes, plus 30 second additions, a bright interior light for monitoring food and quiet low-noise operation suited to open plan kitchens. Build touches like stable footing, wipe-clean door and child lock plus Eco display dimming add family friendly practicality. Critiques focus on setup quirks rather than cooking performance, including vent clearance needs and clock format limits, but overall satisfaction remains high for even heating and intuitive controls.
- Spacious 23L interior heats evenly and easily fits large dinner plates
- Grill plus combination modes deliver crisped, browned results beyond basic reheating
- Intuitive express controls with 11 power levels and 20 auto menus
- Quiet operation with bright interior visibility and wipe-clean mirrored front
- Clock offers limited display format with no 24-hour option reported by owners
- Side vent and rear cable routing need careful clearance and time cannot be adjusted mid-cycle
02
Flatbed freedom with grill versatility in a compact footprint
Built around a flatbed rather than a turntable, this 20-litre Sharp maximises usable space for rectangular and oversized dishes while simplifying wipe-down cleaning, a benefit repeatedly highlighted in verified owner sentiment. The stainless steel, glass and plastic cavity feels contemporary in black, with touch controls, dial input, LED lighting and a clear digital display that owners describe as intuitive for everyday reheating, defrosting and timed cooking. Ten power levels, twelve auto programmes and combination microwave plus grill modes add flexibility for jacket potatoes, ready meals, fish and browning tasks, though several users find the grill strongest in the centre and better for finishing than full grilling. Market feedback praises even heating, quiet convenience features like child lock, ECO mode and mutable alerts, but also notes operational noise and isolated reports of interior paint bubbling and rust after extended use, suggesting diligent drying and ventilation matter for longevity.
- Flatbed interior fits rectangular containers and wipes clean easily
- Even microwave heating with intuitive touch and dial controls
- Versatile solo and combination grill for browning and crisping
- Thoughtful extras like ECO mode, child lock, LED light and mute function
- Grill coverage can feel centred and less powerful for heavy grilling
- Isolated owner reports of operational noise and interior coating wear over time
03
Extra-large family capacity with fast heating and true grill crisping power
Positioned as a large-family grill microwave, this 28-litre Sharp pairs a stainless-steel-led exterior with glass turntable and grill rack for even reheating, defrosting and browning. Market research shows verified owners consistently praise its fast 900W heating, roomy cavity for dinner plates and batch items, and useful 12-program menu covering drinks, plates and time-weight defrost. Everyday ergonomics are mixed but generally positive, with touch controls plus dial, LED clock, kitchen timer and child lock, alongside ECO mode and bright LED cavity light for efficiency and visibility. The silver handle-less design wipes clean easily and suits modern countertops, though its wide footprint and 16.6kg weight demand dedicated space. Satisfaction skews strongly positive at 4.3 stars, tempered by feedback that power percentages feel confusing versus watts and the display can be hard to read, plus an isolated dial reliability report. Overall, it fits households wanting spacious, grill-capable convenience without stepping to full combination cooking.
- Generous 28-litre capacity handles large dinner plates and batch items easily
- Strong 900W microwave plus 1000W grill speeds reheating with browning capability
- Useful 12 auto programs including drink reheat, plate reheat and time-weight defrost
- Thoughtful touches like ECO mode, LED cavity light, child lock and easy-wipe finish
- Power shown as percentages rather than watts feels counter-intuitive for some users
- Control panel and display can be hard to read in low light and takes time to learn
- Wide, heavy countertop footprint needs generous dedicated kitchen space
04
Even inverter heating and proper grill crisping in a roomy 29L family footprint
Positioned as Panasonic’s spacious grill-microwave middle ground, this 29L model pairs a stainless steel front and glass door with inverter power control rather than traditional pulsed heating. In daily use, verified owners report noticeably even reheating, gentle defrosting without rubbery edges, and effective grill browning for gratins, fish and toast, with combination mode cutting wait time versus a full oven. The cavity earns frequent praise for swallowing large dinner plates and soup cartons while staying relatively condensation-free and quiet, and the Aqua Clean cycle simplifies wipe-downs. Ergonomics are mixed. The touch controls, dial and 18 auto programmes are versatile once learned, but legends are small, programs display as numbers requiring the door chart, and the downloadable manual was difficult to locate for some buyers. The light 11kg chassis can shift when opening the door, and brushed steel needs regular wipedown to hide prints. An isolated sparking complaint on the baked potato cycle bears noting despite broadly solid cooking satisfaction.
- Even inverter reheating and thorough defrosting without cooked edges
- Effective grill and combination mode for gratins, meats and toast
- Spacious 29L cavity fits large dinner plates while staying quiet and low-condensation
- Helpful auto programmes plus Aqua Clean for easy maintenance
- Light chassis can slide when pressing door release and feels less planted than heavier combis
- Small low-contrast button legends and number-only programme display create a learning curve
- Brushed steel shows fingerprints readily and manual was hard to locate for some owners
Buyer Questions and Expert Answers
What is the best overall grill microwave for most homes in the United Kingdom?
The Toshiba 23L Black Mirror Digital Grill Microwave is the most balanced choice. Its 900W microwave with 11 levels plus 1000W grill and dual combination modes handles everyday reheating while adding genuine crisping and browning, and the 23L cavity fits large dinner plates without dominating the worktop.
Is a grill microwave actually better than a solo microwave for crisping?
Yes, for texture. A solo microwave heats with microwaves only, which is fast but leaves food soft. A grill model adds a radiant grill element and combination modes that brown cheese on toast, crisp chicken skin, finish jacket potatoes and revive pizza and pies far more effectively.
Should I choose a flatbed or a turntable grill microwave?
Choose flatbed if you use rectangular meal-prep containers and want the easiest wipe-clean with no turntable to wash. Choose a turntable if you mostly reheat round plates and want wide, rotating heat coverage, especially for grilling larger items.
What size grill microwave do I need for UK dinner plates?
For standard large dinner plates around 27cm, 23L is the safe all-round size. Pick 20L flatbed only if worktop space is tight and you cook for one to two people. Pick 28L if you regularly reheat family plates, batch cook, or defrost larger joints and need extra height and width.
How do I keep a grill microwave clean and long-lasting?
Wipe spills after each use once cool, wash turntable or wipe flatbed with warm soapy water, and run a bowl of water with lemon for 3-5 minutes to loosen grease before wiping. Avoid metal scourers on coatings, never run the grill empty, and leave side and rear ventilation gaps to prevent overheating.
The Bottom Line
- 🏆 Top Overall Choice: Toshiba 23L Black Mirror Digital Grill Microwave — best balance of even 23L heating, 1000W grill with dual combi modes, and intuitive everyday controls
- 💰 Best Value: SHARP YC-QG204AU-B Compact 20 Litre 800W Digital FLATBED Microwave with 1050W — ideal for small kitchens with easy-clean flatbed and versatile solo-combi grilling
- ⭐ Premium Pick: SHARP YC-PG284AU-S 28 Litre 900W Digital Microwave with 1000W Grill — pick for families needing maximum capacity and fast reheating with browning capability
For most UK buyers, a mid-size grill microwave with true combination cooking hits the sweet spot between speed and texture, without demanding a full oven. Choose the spacious, easy-to-learn all-rounder if you want one machine for reheating, defrosting and browning, go compact flatbed if space and easy cleaning matter most, and step up to 28L only if you regularly cook for a family. Prioritise clear watt controls, usable auto menus and a cavity you can wipe in seconds, and your grill microwave will earn its worktop space daily.
