If you need a 13-amp oven replacement and can’t decide between a halogen oven and an air fryer, you’re not alone. They’re the two most popular countertop cooking appliances in the UK — both plug into standard sockets, both use hot air, and both claim to replace your oven. But they’re very different in practice.

This guide breaks down the differences on everything that matters: cooking results, running costs, reliability, and value for money.

At a Glance

What Is a Halogen Oven?A halogen oven is a large glass bowl with a halogen heating bulb in the lid, combined with a fan to circulate hot air. The food sits in a basket or on a rack inside the glass bowl, and the intense heat from the halogen bulb cooks it from above while the fan circulates.The classic model: JML Halogen Oven. Most people in UK forums mention JML, but there are other brands including Prolectrix Halogen Convection Oven and Andrew James.The appeal: They’re cheap. A decent halogen oven costs £40–£60, making them the most affordable oven alternative you can plug into a 13-amp socket. The glass bowl means you can watch your food cook without opening the door (losing heat).What Is an Air Fryer?An air fryer is a compact convection oven. It uses a heating element and a powerful fan to circulate hot air at high speed — that’s where the “fry” part comes from. The rapid air movement creates a Maillard reaction (browning) on the outside of food, giving you a crisp texture similar to deep frying, but with a fraction of the oil.Popular models: Ninja Dual Tray Air Fryer, Sage Smart Oven Air Fryer, Tower Air Fryer.The appeal: They’re fast and versatile. An air fryer preheats in 2–3 minutes, and most modern dual-drawer models can cook two different foods at different settings simultaneously.Head-to-Head Comparison1. Cooking Results — ChipsThis is the classic UK test: can it make good chips?Halogen oven: Good, but not great. Chips come out cooked and lightly browned, but they’re more “oven-baked” than “fried.” You’ll get a soft inside and a slightly crisp outside. The results depend heavily on tossing the chips in oil and turning them halfway through.Air fryer: Excellent. The high-speed air circulation creates a genuinely crispy exterior while keeping the inside fluffy. This is where air fryers really earn their name. Frozen chips in an air fryer come out noticeably better than in a halogen oven.Winner: Air fryer (for crispy results)2. Cooking Results — Roast ChickenHalogen oven: Very good. A whole chicken roasts evenly, with well-browned skin and juicy meat. The glass dome means you can monitor browning. A 1.5 kg chicken takes about 60–70 minutes. The only downside: the chicken can sit quite close to the top element, so you may need to tent it with foil near the end.Air fryer: Good, but limited by size. A whole chicken just barely fits in a standard air fryer basket. You’ll get excellent crisp skin, but you’ll need to truss the bird tightly to fit. Dual-drawer air fryers can’t fit a whole chicken in one drawer — you’d have to spatchcock (flatten) it.Winner: Halogen oven (for whole roasts)3. Cooking Results — Cake and BakingHalogen oven: Avoid. The bulb sits close to the top of the bowl, and a cake that rises will hit it. You also can’t get even heat distribution across a cake tin. Most halogen oven users don’t even attempt baking.Air fryer: Surprisingly good. Air fryers can bake small cakes, brownies, muffins, and even bread rolls. The results are even and the short preheating time makes them quick. The Ninja Foodie range has specific bake settings.Winner: Air fryer (for baking)4. Running CostsBased on research from MoneySavingExpert forum members:

• Full-size fan oven (95 min at 180°C): 1.6 kWh ≈ 24p
• Halogen oven (60 min at 180°C): ~0.8 kWh ≈ 12p
• Air fryer (35 min at 180°C): ~0.9 kWh ≈ 13p

At first glance, halogen wins on raw energy per cook. But air fryers often finish cooking faster — a batch of chips takes 15–18 minutes in an air fryer vs 25–30 minutes in a halogen oven. So per meal, they’re roughly neck and neck.Winner: Tie (both cost significantly less than a full-size oven)5. Reliability and DurabilityThis is where the two diverge most clearly.Halogen ovens: The standard complaint — across dozens of MSE forum posts — is that the halogen heating element fails after 4–6 months of regular use. Replacement elements can be bought for ~£10, but that gets tedious. The glass bowl is also fragile; break it and you need a whole new unit.Air fryers: Modern air fryers typically last 2–5 years without issues. The sealed heating element is better protected than a halogen bulb. The non-stick basket coating can start peeling in cheaper models after 12–18 months, but mid-range brands (Ninja, Cosori, Sage) hold up well.Winner: Air fryer (significantly more durable)6. Counter SpaceHalogen ovens take up more surface area because they’re round, and the lid needs room to lift up. Air fryers are more compact, especially single-drawer models.Winner: Air fryer (more compact and stackable shape)7. Ease of CleaningHalogen oven: The glass bowl goes in the dishwasher (check the manual). The metal rack and basket are typically dishwasher-safe too. The lid — with the element and fan — must be hand-washed carefully to avoid damaging the bulb.Air fryer: The non-stick basket and drip tray are dishwasher-safe on most models. The heating element inside the top of the unit can get greasy, but many models now come with a removable top cover or are designed for easy wipe-down.Winner: Tie (both reasonably easy to clean)8. VersatilityHalogen oven extras: Because the bowl is sealed, halogen ovens can be used for steaming (add a little water to the base) and can even cook rice. Some come with an extender ring to increase capacity.Air fryer extras: Most modern air fryers have multiple functions — air fry, roast, bake, reheat, dehydrate, and sometimes even grill. Dual-drawer models can sync cooking times so both trays finish at the same moment.Winner: Air fryer (more preset functions, dual-zone cooking)When to Choose a Halogen OvenChoose a halogen oven if:
– You’re on a very tight budget (under £60)
– You regularly roast whole chickens or large joints of meat
– You want to steam vegetables or cook rice alongside roasting
– You like the idea of watching food cook through the glass dome
– You cook for 3–4 people regularlyBest scenario: A household that roasts meat once or twice a week, doesn’t bake much, and wants a budget oven replacement. The JML Halogen Oven is the standard starting point.When to Choose an Air FryerChoose an air fryer if:
– You value crispy chips, roast potatoes, and crunchy coatings
– You bake small cakes, muffins, or bread
– You’re the primary cook for 1–2 people
– You want better durability and longer appliance life
– You’re happy spending £70–£150Best scenario: A household of 1–2 people that wants fast, crispy results, bakes occasionally, and values longevity. The Ninja Dual Tray Air Fryer is the most versatile option.Can You Have Both?Some dedicated cooks do. The halogen oven handles large roasts and steaming; the air fryer handles chips, snacks, and quick meals. Combined, they cost around £100–£150 — still well under the cost of one full-size cooker circuit installation. But for most households, buying one or the other based on your cooking style is the better choice.The VerdictFor most UK renters and flat dwellers in 2026, an air fryer is the better all-round choice. It’s faster, more versatile, more durable, and produces better results on the foods people cook most — chips, chicken, and quick meals. The only exception is if you need to roast whole chickens regularly or you’re on a very tight budget, in which case the halogen oven still holds its own.Bottom line: Spend £80–£120 on a mid-range air fryer and you’ll probably never need a halogen oven. But if you see a halogen oven going for £30 at a supermarket, it’s a perfectly good backup.
