10 Best Microwaves Under 300 of 2026
Buying Guide
Capacity and size
Think about how much you’ll cook and the space available in your kitchen. Small flats often suit 17–23-litre models, while families may prefer 25–30+ litres; measure the interior turntable diameter to ensure plates and dishes fit.
Power and cooking performance
Microwave power, measured in watts, affects cooking speed and evenness - 700–900W is typical for everyday use, with 1000W+ better for faster cooking. Also look for variable power settings and inverter technology, which provide gentler, more consistent heating.
Functions and cooking modes
Decide whether you need basic reheating, a grill function, or full convection/air-fry capabilities; grill and combination modes add browning and crisping but can push the price up. Useful extras include sensor cooking, quick-start presets and defrost by weight for convenience.
Controls, build quality and cleaning
Simple dial controls are reliable and great for everyday use, while touch panels and digital displays offer finer control and presets. Check the cavity finish (easy‑clean enamel is preferable), removable turntables and whether the door and ventilation suit your kitchen layout.
Price, warranty and retailer support
Set a realistic budget - there are strong options under £300 that balance features and reliability; expect to pay more for convection and larger capacity. Buy from reputable UK retailers (Currys, AO, John Lewis, Argos) and look for at least a 12‑month guarantee or an extended warranty option.
