The microwave is the most under-appreciated appliance in most kitchens — used multiple times a day but rarely replaced until it breaks. Three specs actually matter: wattage (900W heats faster and more evenly than 800W), cavity size (20L suits 1–3 people, 25–27L suits families), and whether you want grill or oven functions.
💰 Best Under £55 — Daewoo 800W 20L Manual
The most affordable reliable microwave on our list. Simple manual controls, 6 power levels, and a 30-minute timer — no confusing digital menus, just heat and go. For students, small flats, or a second microwave for a utility room, it does the job at minimum cost.
- Excellent price point
- Simple manual controls — easy to use
- 6 power settings
- Easy interior to wipe clean

⭐ Best Overall — Russell Hobbs RHM2076B Digital 20L
8,200 Amazon reviews at 4.4 stars — this is the UK's best-selling microwave and earns that status. The digital display and 8 auto-cook menus mean you press one button for pizza, potatoes, fish, or vegetables and it handles the rest. 5 power levels and auto-defrost round out a complete package.
- 8,200+ reviews — proven UK bestseller
- 8 auto-cook menus — genuinely useful
- Digital display + 5 power levels
- Auto-defrost function
- 800W — not the fastest

🎯 Best Mid-Range — Sharp YC-MS252AU 25L 900W
The step-up that matters. 900W vs 800W noticeably speeds up cooking and improves evenness. The 25L cavity fits a family-sized bowl or covered dinner plate easily. 11 power levels give precision that cheaper models can't match, and ECO mode reduces standby power. Sharp microwaves are exceptionally well-built and this model shows why.
- 900W — faster, more even heating
- 25L — family capacity
- 11 power levels for precision
- ECO standby mode saves energy
- No grill or oven modes
- Silver finish shows fingerprints
- £20 more than 20L alternatives
🏆 Best Premium — Panasonic NN-CT56JBBPQ Combination 27L
The best combination microwave available at a non-industrial price. Panasonic's inverter technology delivers continuous, even microwave power (no hot/cold spots), while the full grill and convection oven modes mean you can roast, bake, and brown. 27L cavity fits a whole chicken. If you want one box to do everything, this is it.
- Full combination: microwave + grill + convection oven
- Inverter tech — consistent, even cooking
- 27L large cavity
- 2,800+ reviews at 4.4★

📡 Microwave buying guide
Here are the specs that actually change what you can cook:
- Wattage: 900W heats more evenly and faster than 800W. For everyday reheating it's noticeable. Inverter models (Panasonic) deliver continuous 900W rather than pulsing on/off — the biggest heating quality upgrade available.
- Capacity: 20L suits 1–3 people. 25L fits a family-sized bowl or covered plate. 27L fits a whole chicken. Most people underestimate how important this is until they try to fit a large dish.
- Solo vs combination: A solo microwave reheats and defrosts. A combination model also grills and bakes — meaning it can genuinely replace a second oven in a compact kitchen.
- Auto-cook programs: Presets for pizza, potato, fish, and vegetables are genuinely useful — press one button and walk away. Budget models often lack these.
- Flatbed vs turntable: Flatbed models (Panasonic) have no carousel to wash and more usable interior space. Most affordable models still use turntables.
