Best Built-in Microwaves Under £500 in 2026
The £300 to £500 bracket is where most UK households shop for built-in microwaves, and for good reason. You get proper grill functions, decent cavity sizes, and reliable brand names without the premium attached to combination ovens or steam features. In 2026, this price point delivers solid performers from Hotpoint, Whirlpool, and Indesit. These are hand-picked models that work day in, day out, not fancy showroom pieces that cost more to repair than replace.
We're a UK family-owned business based in Bournemouth. Every microwave we stock comes with manufacturer warranty, UK based support if something goes wrong, and 14 day free returns if it's not right for your kitchen. We've been doing this since 2009, long enough to know which models actually last.
What You Get at This Budget
- Cavity sizes from 22L to 40L. The smaller 22-25L models suit compact spaces or light use. The 31L and 40L options handle family portions and larger dinner plates without rotating them mid-cycle.
- Combination microwave and grill functions. Every model in this range includes a grill element. You can brown the top of a lasagne or crisp bacon without firing up the main oven. Grill power varies from 700W to 1600W, which affects how quickly things colour.
- Stainless steel or black finishes. Both hold up well in daily use. Stainless shows fingerprints more but looks sharper in modern kitchens. Black hides marks better and suits traditional or gloss units.
- Digital controls and pre-set programmes. No more twisting dials and guessing cook times. Most models include auto-cook menus for common foods like jacket potatoes, fish, or frozen vegetables.
What You Sacrifice at This Budget
- No convection or fan oven capability. These are microwave and grill combinations, not full combo ovens. If you want proper baking or roasting functions, you need to spend £600 and up. The grill here browns surfaces but doesn't circulate heat like a fan oven.
- Build quality is functional, not luxury. Door mechanisms feel solid enough but lack the damped, soft-close action of premium models. Interior coatings are enamel rather than self-cleaning ceramics. They clean fine with a cloth but aren't wipe-clean miracles.
- No steam cleaning or pyrolytic features. You scrub these by hand. A bowl of water with lemon juice run on high for three minutes loosens splatter, but you still need elbow grease for baked-on cheese.
Our Top Pick Under £500
Whirlpool WMD54MXUK at £419
This hits the sweet spot for reliability and features. Whirlpool's build quality edges ahead of budget Hotpoint and Indesit models. The stainless steel finish looks clean in any kitchen style, and at this price you get a brand with responsive UK service centres.
The cavity is generous without being oversized, the controls are clear enough that you won't need the manual after the first week, and the grill performs well for melting cheese or crisping the top of a cottage pie. It's not flashy. It just works consistently, which matters more than marketing features when you're using it twice a day.
We stock this because we've seen very few warranty claims on Whirlpool microwaves compared to cheaper brands. At £419, it sits comfortably mid-range without the markup of premium models that offer little extra in real-world use.
Runner-Up Picks
Hotpoint HMD44MXUK at £394
If you want to save £25 and still get a 31L cavity, this Hotpoint delivers. It's a Class 4 model with 1000W microwave power and 800W grill. The active Crisp function works well for reheating pizza or cooking frozen pastries without sogginess. Stainless steel finish matches most integrated appliances.
Hotpoint's Class 4 range sits above their budget Class 2 and 3 models. You get better door seals, more even heating, and controls that feel less plasticky. At £394, it's solid value if Whirlpool's £419 feels like a stretch.
Hotpoint HMD44MBUK at £383
This is the black version of the model above. Same 31L capacity, same 1000W microwave and 800W grill, same active Crisp function. It's £11 cheaper than the stainless steel version purely because black isn't as popular this year. If your kitchen has black appliances or dark units, this saves you a few quid without sacrificing anything functional.
Indesit IP252RXUK at £385
The largest cavity here at 40L. If you regularly cook for four or more, or need to fit big casserole dishes, this Indesit accommodates them. The 900W grill is less powerful than some competitors, so browning takes longer, but the extra space is genuinely useful for batch cooking or large plates.
Indesit sits below Hotpoint and Whirlpool for build quality, but at £385 for 40L, you're getting exceptional capacity per pound. The quartz grill heats evenly across the cavity width, which matters when you're grilling something large.
When to Stretch Your Budget
If you bake regularly or want a second oven that handles more than reheating and grilling, consider spending £600 to £800 on a combination model with convection. Those include fan oven functions that actually bake bread, roast chicken, or cook pastry properly. The models in this guide can't replace an oven. They're brilliant at what they do, microwave heating and surface grilling, but they don't circulate hot air for even baking. If you only need microwave and grill functions, spending more buys you fancier controls and finishes, not better cooking results. Save the money.
