Microwaves are one of those product categories where the honest answer is "buy the cheap one." The £80 Panasonic basic does daily reheat, defrost, and the occasional bowl of popcorn. There's nothing more a microwave needs to do for households who already have a full oven, and there's no premium feature in the £200-£400 tier that justifies the price for that use case.
The exception: combi microwaves (microwave plus grill plus convection) at £250-£330 genuinely earn their place in flats or households without a separate oven. They're a different product solving a different problem, and confusing them with basic microwaves is the most-common buying mistake.
How to pick
Most UK households (have a full oven): Panasonic NN-E27JWMBPQ basic at £80-£120.
Flat / no full oven, want versatile cooking: Toshiba ML-EC42P combi at £250-£330.
Premium build, longevity: Sharp R372 at £140-£180.
For most UK households with a full oven: Panasonic basic microwave at £80-£100. Genuinely covers daily reheat / defrost / popcorn needs.
For flats without separate oven: Toshiba combi microwave at £280. Microwave plus grill plus convection oven in one unit; replaces separate oven for basic cooking.
The three worth knowing
Panasonic NN-E27JWMBPQ at £80-£120. The mainstream microwave. 800W, 23L capacity, basic controls. Does what microwaves do reliably.
Toshiba ML-EC42P combi at £250-£330. Combines microwave (fast reheat), grill (browning), and convection (oven-style cooking). For flats or single-occupant households, replaces a full built-in oven for many cooking tasks. 42L capacity is generous. More expensive than basic microwave; smaller than full oven (Sunday roast for 6 doesn't fit); steeper learning curve.
Sharp R372 at £140-£180. Premium-tier basic microwave. 25L capacity, build quality slightly better than Panasonic, longer expected lifespan.
How I'd actually pick
UK households with full ovens: Panasonic NN-E27 basic at £100. Don't overpay; basic microwave covers basic microwave needs.
Flats / studios without full oven: Toshiba ML-EC42P combi at £300.
UK households wanting slightly more durable basic microwave: Sharp R372.
What I'd swerve: cheap (£40-£50) microwaves from supermarket brands (typically die within 2-3 years); over-priced "smart" microwaves with app connectivity; built-in microwaves at £400-plus unless specific kitchen design requires it.
The £80 Panasonic versus the £300 Toshiba combi isn't a quality decision — it's a different-product decision. Pick the one that matches what you'll actually use it for.
