Buying Guide
Capacity and footprint
Check the internal capacity (litres) and the unit’s external size to ensure it fits on your worktop or in a cupboard. For one or two people a 17–20L model is usually fine; families may prefer 23L or above, but larger models often push past the £100 mark.
Power and cooking performance
Wattage affects how quickly and evenly food cooks - most budget microwaves range from 700W to 900W. Aim for 800W+ if you want faster reheating; lower wattages are slower but can be gentler for delicate foods.
Functions and programmes
Basic models will offer power levels and defrost, while some under £100 include auto-cook programmes and a grill function. Decide which features you actually use - a simple, reliable microwave with manual power settings can be better than a feature-rich model with poor performance.
Build quality, reliability and warranty
Look for trusted brands and check reviews for long-term reliability; cheaper models can vary in build quality. A minimum one-year warranty is standard in the UK, but longer guarantees are a useful sign of confidence from the manufacturer.
Running costs and safety
Microwaves are generally economical to run, but check standing power and energy-efficiency comments in reviews. Also ensure it meets UK safety standards, has child-lock options if needed, and that replacement parts (like turntables) are readily available from UK retailers.
