For a small first flat with a hob and a full-size oven, buy an air fryer first (editorial judgement). In the Energy Saving Trust’s lab test of one meal, a 600g chicken breast cost £0.14 to cook in an air fryer against £0.20 in an electric oven in Great Britain, and it says air fryers suit one or two people while an electric oven is better for batch cooking or cooking for a large group.[1] The right first buy depends on what the flat already has:
- Hob and full-size oven: An air fryer or air fryer oven adds hot-air cooking for small portions, and the oven is the better tool for batch cooking.[1]
- No oven: A mini oven or air fryer oven covers baking, grilling and toasting in a worktop-sized cavity.
- No hob: A mini oven with hot plates adds boiling and frying surfaces.
- Mostly reheating: The Energy Saving Trust describes the microwave as best for reheating and quick cooking, with a typical cost of £0.04 to cook a 400g ready-made lasagne.[1]
Before buying, check five things on the product page: footprint, capacity, functions, wattage, and cleaning and cover terms. The running costs are the Energy Saving Trust’s typical figures for specific foods.
What Counts as a Compact Cooking Appliance?
A compact cooking appliance is a worktop-sized appliance that cooks, heats or reheats food on its own. In a small flat it usually means a basket air fryer, an air fryer oven, a mini oven, a mini oven with hot plates or a microwave. It makes sense as a first buy when it cooks the meals you make most often and does something your main oven or hob does less conveniently.
Which Type of Compact Cooking Appliance Suits Which Kitchen?
| Type | Best for | What it adds beside a full-size oven | Main drawback | Typical cost per use (Energy Saving Trust) |
| Basket air fryer | One or two people cooking small portions | Fast hot-air cooking in a basket or drawer | Basket size limits how much cooks at once | £0.14 for a 600g chicken breast (GB)[1] |
| Air fryer oven | Small portions plus baking and toasting | Hot-air cooking in an oven-shaped cavity, usually with a basket, rack and tray | Bigger footprint than a basket model | Not stated by the source |
| Mini oven (toaster oven) | Toast, baking, grilling and reheating without heating a full-size oven | Baking, grilling, roasting and toasting in a compact cavity | Check whether the page lists an air fry mode | Not stated by the source |
| Mini oven with hot plates | Flats with limited or no hob space | One or two hot plates for boiling or frying | The hot plates add to the total wattage | Not stated by the source |
| Microwave | Reheating and quick cooking | Heats the food directly rather than the air around it[1] | Results differ from an oven or air fryer | £0.04 for a 400g ready-made lasagne (GB)[1] |
Note: The Best for, What it adds and Main drawback columns are editorial descriptions. The costs are the Energy Saving Trust’s lab-tested figures for different foods, and the page does not state the energy prices used, so treat them as indicative and compare an air fryer with an electric oven (£0.20 for the same chicken breast), not one row with another.[1]
What if the Flat Has No Oven or No Hob?
A flat without a full-size oven needs the compact appliance to do the baking, so a mini oven or air fryer oven makes sense as the first buy, with a microwave added for reheating. A flat without a hob needs a cooking surface, and a mini oven with hot plates provides one or two for boiling and frying. The hot plates add to the appliance’s total wattage, so check that against your socket.
Using the hob is typically quite cheap where there is one, according to the Energy Saving Trust, which gives a typical cost per use of £0.11 to £0.28 in Great Britain without naming a food, so it is not directly comparable with the figures above.[1]
Which Specialist Appliances Can Wait?
A deep fat fryer, an electric pizza oven or a food dehydrator each does one job, so it is a second purchase, once a task keeps falling outside your first appliance. For example, a food dehydrator suits someone who dries fruit or herbs often, not someone cooking everyday meals.
Key Factors: What Decides Your First Compact Appliance?
- Footprint: The outside width, depth and height decide whether the appliance fits your worktop and the space under your cabinets. A larger interior usually means a larger footprint.
- Capacity: A stated food capacity, such as a pizza size, a chicken weight or a number of bread slices, shows what one batch looks like. A bigger cavity helps a shared flat and wastes space for one person.
- Functions: Choose functions your main oven does less conveniently, such as air frying, toasting or hot plates. A function it already does adds little.
- Power: The stated wattage shows how much of a socket the appliance uses. A 13-amp socket supplies about 3,000 watts at 230 volts, so a high-wattage appliance leaves little for anything else on the same socket.
- Cleaning and cover: Named removable parts and washing wording show how easy the upkeep is. Under the Consumer Rights Act 2015, goods must be of satisfactory quality, which takes the price into account where relevant, and durability is one of the aspects of quality in appropriate cases.[2]
How to Choose Between a Versatile First Buy and a Specialist Second Buy
- List the five meals you cook most often and the number of people you cook for. These set the capacity you need.
- Write down what your main oven and hob already do well, then cross out any function a new appliance would only repeat.
- Measure your worktop space, the height under your cabinets and the reach of your socket, then compare them with the outside dimensions on each product page.
- Shortlist two or three appliances and note the functions, capacity, wattage and weight for each, writing “not stated” wherever a page is silent.
- Treat anything not stated as unconfirmed: a food capacity, a washing claim or a certification the page does not name cannot count in an appliance’s favour.
- Rank what is left by fit (footprint and power), then what it adds beside your main oven, then cleaning and cover, then price.
- Buy the versatile appliance first, and add a specialist appliance only when a task keeps falling outside it.
Standards and Evidence: What Do the Rules and Safety Advice Say?
- Safety law: Electrical equipment has to meet the safety objectives set out in the Electrical Equipment (Safety) Regulations 2016.[3]
- Markings: GOV.UK states that the UK continues to recognise the CE marking, alongside or in place of the UKCA marking, for the Great Britain market.[4]
- Product standard: BS EN IEC 60335-2-9:2023+A11:2023 is the safety standard for grills, toasters and similar portable cooking appliances, and BSI lists it as current. A product page that names a standard shows which one the maker refers to.[5]
- Safe use: Electrical Safety First, a UK electrical safety charity, advises keeping power cables away from hot surfaces and worktop edges, never leaving an air fryer unattended while it is in use, not overfilling it beyond the maximum fill level in the instructions, and registering it so you can be contacted if there is a safety recall.[6]
- Cleaning: It also advises unplugging an air fryer at the socket when you have finished cooking, and waiting at least 30 minutes before cleaning it so it cools down fully.[6]
Worked Example: Two Appliances Against the Same Worktop
Imagine a flat with 50cm of free worktop width and one socket within reach, which supplies about 3,000 watts. Two HOMCOM appliances show how the checks play out. They are examples, not rankings, and a different kitchen would rule different appliances in or out.
1) HOMCOM 8L Dual Basket Air Fryer:[7]
- Capacity and functions: 8 litres in two 4-litre baskets that can be controlled separately, with 8 presets and 80 to 200°C.
- Size and power: 38.5 x 38 x 30.5cm outside (width x depth x height), 7.5kg and 2500 watts with both baskets running.
- Against the 50cm worktop: It fits the width, and its wattage leaves some of the socket free.
2) HOMCOM 36L Mini Oven with Dual Hot Plates:[8]
- Capacity and functions: 36 litres, with a convection fan, 90 to 230°C, a rotisserie spit for a whole chicken up to 2kg and two hot plates of 790 and 610 watts.
- Size and power: 53.1 x 37.5 x 39cm outside (length x width x height), 11.5kg and 2850 watts in total. The page’s comparison table lists 1500 watts, which conflicts with that total, so confirm the wattage before relying on it.
- Against the 50cm worktop: If its 53.1cm length runs along the worktop, it does not fit the 50cm width. Turned so the 37.5cm side faces front it would fit, but its 39cm height and 11.5kg weight still need checking, and 2850 watts would use nearly all of the socket.
Common Mistakes to Avoid
- Buying the biggest cavity: A larger interior needs more worktop and often more power, and it only helps if you cook for more people.
- Measuring the interior but not the outside: The litres describe the cavity, while the outside width, depth and height decide whether it fits your worktop and under your cabinets.
- Ignoring the wattage: A high-wattage appliance uses most of a socket’s capacity, so check it against the sockets you have.
- Overfilling to save time: Electrical Safety First advises staying within the maximum fill level in the instructions.[6]

The Best Choice for Your Flat
For a small first flat, buy an air fryer first if you have a hob and a full-size oven, a mini oven or air fryer oven if you have no oven, a mini oven with hot plates if you have no hob, and a microwave if you mostly reheat. These are editorial judgements. Check the outside dimensions, capacity, functions, wattage, and cleaning and cover terms on the product page, and add a specialist appliance only when a task keeps falling outside your first one.
FAQs
1. Can you bake a cake or roast a whole chicken in a mini oven or air fryer oven?
Yes, if the stated food capacity allows it. The HOMCOM 36L mini oven you list includes a convection fan, 90 to 230°C and a rotisserie spit for a whole chicken up to 2kg at time of writing, while a basket air fryer is limited to its basket size. Check the pizza size, chicken weight or number of slices on the product page before ordering.[8]
2. Can a mini oven with hot plates boil water and fry when there is no hob?
Yes. A mini oven with dual hot plates gives you one or two plates for boiling and frying where a flat has no hob. The HOMCOM 36L you list shows 790W and 610W plates with 90 to 230°C and convection at time of writing, so check the total wattage of 2850W against your socket and the outside size of 53.1 x 37.5 x 39cm against your worktop.[8]
3. Does an air fryer oven toast bread or only air fry?
A basket air fryer focuses on air frying small portions in a drawer. An air fryer oven or mini oven with a rack and tray adds baking, grilling and toasting in an oven-shaped cavity, so check the functions on the product page. At time of writing, the HOMCOM 8L lists 8 presets and Preheat, while the HOMCOM 36L lists convection, 90 to 230°C and dual hot plates for boiling and frying, which shows the difference in what each adds beside a full-size oven.[7][8]
