Buying Guide
Capacity and footprint
Check the internal litre capacity and the external dimensions to make sure the microwave fits your kitchen and plates. For solo occupants or small flats, a 17–20 litre model is usually fine; families will prefer 23 litres or more.
Power (watts) and cooking speed
Wattage determines how quickly and evenly food cooks - budget models typically range from 600–900W. Aim for 700–800W for a good balance of speed and energy use; remember to adjust recipe times if you move between different wattages.
Controls and features
Decide whether you want simple mechanical dials or digital controls with preset programmes, which can make everyday tasks easier. Look for essentials such as an auto-defrost function, turntable, child lock and adjustable power levels rather than niche extras that push up the price.
Build quality and ease of cleaning
A wipe-clean enamel interior and a removable turntable make maintenance straightforward - important for heavily used machines. Check the door and hinge feel; a flimsy door or poor finish often predicts shorter lifespan in budget units.
Price, warranty and retailer support
Under £100 there are many capable microwaves, but compare warranty terms (1–2 years is common) and return policies from UK retailers like Argos, Currys, AO or Amazon. Consider delivery and click‑and‑collect options, and whether the seller offers a longer guarantee for a small extra cost.
Frequently Asked Questions
What is the best microwave under £100 in 2026?
There isn’t a single best model for everyone - the ideal choice depends on capacity, wattage and controls. In 2026, look for a 20–23 litre microwave with 700–800W, a reliable turntable and a simple defrost programme from a recognised brand sold through UK retailers like Argos or Currys.
Is a microwave under £100 worth buying in the UK?
Yes - for reheating, defrosting and simple cooking tasks a sub-£100 microwave offers excellent value. They’re energy-efficient for short tasks and suit students, small households and secondary kitchens, though they won’t match the versatility of pricier convection models.
Which microwave offers the best value for money?

700W vs 800W - which should I choose?
