The Best Microwaves in the UK for 2026

For most people we rank the Panasonic NN-SD27HSBPQ first: its inverter technology delivers steadier power than standard solo microwaves, which reviewers link to more even reheating and gentler defrosting, and it pairs that with 1000W and a 23-litre cavity. If you want to replace a small oven, the Panasonic NN-CT56JBBPQ combination model grills and bakes as well as microwaves. For the best value, the Samsung MS23K3513AK gives you a full 23 litres and an easy-clean interior for around £99.

It is worth it if you defrost meat or reheat dense or layered dishes more than occasionally. A standard microwave reaches lower power levels by cycling full power on and off, whereas an inverter delivers a continuous, steady output at the set level. In practice that tends to mean more even reheating and defrosting without dried-out edges. For nothing but popcorn and quick full-power reheats, a cheaper standard model does the same job for less.

Most solo microwaves sit at 800W, which is fine for everyday reheating and defrosting; stepping up to 900–1000W simply cooks and reheats faster. Ready-meal instructions are usually written around 800W, so lower-wattage models follow packet times most closely, while higher-wattage ones may need you to shorten the time slightly. Wattage is separate from capacity and from grill or convection power, which are quoted individually.

Capacity is quoted in litres and mostly determines what fits inside. A 20-litre model such as the Panasonic NN-E28JBMBPQ takes a standard dinner plate and suits tight worktops or one-to-two-person households, while 23 litres and up (the Panasonic NN-SD27HSBPQ or Samsung MS23K3513AK) gives more room for larger plates, batch dishes and families. Bear in mind the external footprint grows too, and combination models like the 27-litre NN-CT56JBBPQ are the largest — measure your available space and any cupboard clearance before buying.

A solo microwave only microwaves — it reheats, defrosts and cooks, but cannot brown or crisp. A grill microwave adds a heating element so you can brown or crisp the top of food such as cheese or toasties. A combination microwave adds a convection oven on top of the grill, letting it bake and roast as well, so it can act as a compact second oven. Solo models are cheapest and simplest; combination models are the most versatile and the most expensive.
