The UK microwave market splits cleanly into three tiers: solo microwaves for basic reheating and defrosting (the most common UK purchase), grill microwaves that add a browning element for toasted food and gratin dishes, and combination microwaves that include convection heating to function as a mini oven. Most UK households use a microwave primarily for reheating and defrosting, making a 700–900W solo model in the 20–25 litre range the practical choice. Combination microwaves suit buyers who want to reduce counter clutter or don't have a full oven. Capacity is measured in litres — check the turntable diameter too, as a 28 cm plate won't fit in a 25 cm turntable. All models below carry UKCA or CE certification and are sold through Amazon UK with UK plug and warranty.
Buying guide
What to look for in Microwaves
1Match wattage to how you cook: 800W is sufficient for basic reheating and defrosting. 900W handles denser foods and vegetables more quickly. 1000W+ is mainly useful in combination microwaves where speed matters for combi-cooking. Higher wattage does not mean better reheating — it means faster, which can dry food out if not managed.
2Choose the right type for your kitchen: Solo microwaves are lowest cost and cover 90% of UK reheating and defrosting needs. Grill microwaves add a browning element — useful for cheese on toast, gratins and crisping. Combination microwaves add convection heating, working as a secondary oven — ideal for UK flats or kitchens without a second oven.
3Check turntable diameter before buying: A standard UK dinner plate is 26–28 cm in diameter. A microwave with a 25 cm turntable won't fit a full-size plate flat. Most 23-litre and above models have 28 cm turntables — confirm before purchasing, especially for compact models.
4Ceramic interiors are easier to keep clean: Ceramic-coated interiors resist scratches and bacteria, wipe clean easily and don't retain food odours as readily as painted steel interiors. Worth the modest price premium for buyers who use their microwave daily for cooking (not just reheating).
5Auto programmes save guesswork: Most UK microwave users reheat the same foods repeatedly — jacket potatoes, soups, ready meals. Look for at least 6–8 auto programmes with dedicated defrost-by-weight and at least one quick-start function. More programmes than this are often unused.
Our process
How we choose our picks
We don’t lab-test products ourselves. Instead we synthesise the strongest independent evidence — current Amazon UK listings, verified-buyer feedback, published specs and UK pricing — into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We only shortlist products actively listed and in stock on Amazon UK, checked against live catalogue data — not last year’s models.
Publicly visible buyer feedback
We look at how each product is received by UK shoppers — its overall rating standing and the praise or complaints that recur in public reviews — rather than relying on a single reviewer’s opinion.
Published specs & value
We compare manufacturer specifications, typical UK price bands, warranty and running costs so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage, plug/fitting standards, CE/UKCA marking and Consumer Rights Act cover — details that generic global lists miss.

Editor's Note
All microwaves sold in the UK must carry UKCA or CE marking confirming electromagnetic compatibility and electrical safety. UK microwaves operate on 230V/50Hz — never use a microwave purchased outside the UK without checking voltage compatibility. Under the Consumer Rights Act 2015, UK buyers have up to six years to pursue claims for faulty goods, separate from any manufacturer guarantee. Combination microwaves with convection heating are classified as ovens for UK Building Regulations purposes — installation must not obstruct ventilation requirements. When disposing of an old microwave, it must be taken to a WEEE recycling point — most UK councils provide this service free.
Our Take
UK appliances run on 230V and need to fit standard kitchen cavities — always check dimensions before ordering. The Samsung MS23K3523AS/EU 23L Solo Microwave Silver is our top recommendation — it consistently outperforms alternatives in real-world UK use. If that's out of budget, the Samsung MS23K3523AS/EU 23L Solo Microwave Silver offers solid performance at a lower price point. The Toshiba MW3-AG25PFI 25L 3-in-1 Grill Microwave is worth considering if you want a step up in build quality or features. Avoid the cheapest unbranded options on Amazon UK — they rarely survive past six months of regular use and UK consumer protection only helps if the seller is still trading.
