Wall ovens buying guide

When deciding what size built-in oven to get, think about both the space available in your kitchen and the type of cooking you do.

Single wall ovens

• Standard width wall ovens (600mm) can often be mounted under a bench or cooktop. But models with separate warming drawers are too tall so must be installed in a wall unit.
• Wide wall ovens (900mm) are good if you want to cook two things side by side on the same rack. But they have larger trays that are heavy when fully loaded. The trays and racks are also awkward to clean in a standard kitchen sink.

Be aware that ovens with the same external dimensions and claimed volume don’t all have the same usable internal space. That’s because manufacturers measure differently.

Check out our wall ovens reviews to compare the useable space of the built-in ovens we’ve tested. We measure from the lowest rack or baking tray to the grill element, side wall to side wall, and the rear wall to the door.

Double wall ovens

Double wall ovens are effectively two separate ovens stacked one on top of the other, each with its own door and cooking controls. You can bake in one and grill in the other, or bake two things that require different temperatures, one in each compartment.

They need to be installed in a wall unit due to their height.

Note: We don’t have test results for double ovens at this time.

What oven cooking functions do you need?

Most modern ovens are fan-forced. The fan keeps the air circulating, meaning the temperature is consistent in all parts of the oven so food cooks more evenly.

Fan-forced cooking is also faster. But that’s not suitable for all types of food. Some baked goods need to be cooked slower to prevent the outside burning before the inside is done.

While many fan-forced ovens can be used without the fan, some can’t.

Use our test results to compare wall ovens and see which models have the flexibility of both classic bake and fan-assisted cooking.

You’ll also find some built-in ovens in our test with a steam-assisted cooking function. It’s ideal for baking bread with a fluffy centre and crispy crust.

Wall oven features to check instore

• What’s the useable space? Take your largest baking dish or a measuring tape into the store to check what will fit in the oven. Don’t rely on manufacturer specifications.
• Are there at least two grill tray positions, and a range of rack positions in the main oven?
• Are the controls clearly labelled and easily understood?
• Is there a control panel lock to prevent accidental bumps or curious children from changing the settings?
• Is there a delayed start function? This allows you to set a specific time for the oven to start so you can carry on with other tasks without having to remember.
• Is there a favourites programme you can set?
• Does the oven have rapid heating? This allows you to get cooking sooner, and there’ll be less hassle if you forget to preheat your oven early.
• Does the door window allow a clear view to what’s cooking?
• Is the door easy to open and able to stay open in any position without slamming shut or falling fully open? Some ovens have a soft close door.
• Do all racks stay level, slide smoothly, and have safety stops when pulled out? This will prevent food spilling or the baking dish sliding out unexpectedly.
• Are there telescopic runners? Not essential, but a nice bonus, helping oven racks to stay level and slide smoothly. They can be a bit fiddly to remove, clean and reinstall.
• Is the top element set high into the ceiling and/or have a shield so you won’t easily bump it and burn yourself?
• What accessories are included? We think two oven racks and one baking tray should be standard. A smokeless grill tray would be a good inclusion too, allowing fat and oil to drain through slits into a drip tray, reducing splattering.
• Can the interior light bulbs be replaced easily without a technician?

Self-cleaning oven features

Many modern ovens have a pyrolytic cleaning or steam cleaning function, and some have catalytic liners. Each can make it easier to clean the oven. But what do these terms mean?

Pyrolytic cleaning

Pyrolytic cleaning allows you to clean your oven without chemicals. It’ll heat the oven to around 500°C, converting food residue to ash, which you then wipe or vacuum out. You’ll need to remove and separately wash all runners, racks and other accessories that aren’t stated in the oven’s user manual to be pyrolytic safe.

Although the oven door will be locked during a pyrolytic clean, the outside of the oven will get much hotter than usual – something to be aware of if you have kids. You’ll also need good ventilation as the cooling fan can blow excess air from the oven door.

Steam cleaning

Steam cleaning is another way to clean your built-in oven without chemicals. Steam is either injected into the oven cavity or created by heating water in an oven dish. The steam softens food residue, which you then wipe out. You’ll probably still have to do a little scrubbing.

TIP: You can steam clean many ovens without a specialist function by heating water in an oven dish for 30 minutes at around 150°C. But check the oven’s user manual as some manufacturers state that steam can damage the oven’s internal surfaces.

Catalytic liners

Some wall ovens have catalytic liners on one or more of the internal walls. The liners absorb fat splatters while the oven is in use. Check how many oven walls have catalytic liners as you’ll need to clean all other surfaces yourself, plus the door, rack supports and racks.

While catalytic liners will last a long time when maintained as directed in the oven’s user manual, they might eventually need replacing.

TIP: Don’t line the base of your built-in oven with aluminium foil. This used to be common to help keep the oven floor clean, but manufacturers now warn that it can overheat and damage the surface.

Where to install a wall oven

Whether you’re putting a new wall oven in the place of an old one or choosing a new location, pay close attention to the dimensions and installation requirements in the new oven’s user manual to make sure it’ll fit and function safely.

The oven manual should include specifications for spacing and ventilation, and the cabinetry surrounding the oven may need to be heat resistant to a certain temperature.

If you’re renovating and planning your kitchen layout from scratch, make sure your built-in oven will be handy to your refrigerator, food preparation and clean-up areas. Allow enough space for people to be working in those areas at the same time without getting in each other’s way.

In the past, it was best to keep ovens and refrigerators separated. But modern models of both are better insulated than older ones, so they can often now be placed alongside one another if needed.

Make sure the doors for your cupboards, oven, refrigerator and dishwasher can all be opened fully without clashing with other appliances. It’s a good idea to consider which way your refrigerator door opens too.

If you have younger children, you might choose to mount your built-in oven in an elevated position. Pyrolytic cleaning functions can make the oven exterior quite hot, and curious kids can change your cooking settings or turn the oven on if it doesn’t have a control lock.

You won’t have to bend so far to load and unload oven trays if the oven is elevated. But you might prefer to install your new wall oven under a counter or cooktop, as this provides an area to immediately unload trays. If your cooktop doesn’t have integrated ventilation, install your rangehood or extractor directly above.

Costs of installing a wall oven

Remember to consider installation costs when buying a built-in oven. In addition to locating and installing your wall oven, you may also need to employ licensed tradespeople to ensure a safe power supply.

While some ovens are plugged into a power point, many are hardwired. You’ll need to know how your existing oven is connected and what its power rating is (whether it’s the same as your new oven), so you know whether you need an electrician to wire the new oven.

When you're replacing like with like, existing wiring that’s in good condition will usually be suitable. But always check with the supplier or retailer about the installation requirements for the new model. Large ovens may need a circuit with greater capacity.

If you’re replacing a gas stove with an electric wall oven, you’ll need to employ the help of a licensed gasfitter and electrician.
