If you want the full “big Aga” experience, a 4 oven Aga is often the model people think of first. It gives you four separate ovens and the classic two hotplates, so you can roast, bake, simmer and keep food warm all at once.
On this page we explain what a 4 oven Aga is, which ovens and hotplates you get, how the hotcupboard section works, how much space you need, and the type of home it suits best. We will also point you to detailed guides on temperatures, dimensions, running costs and prices so you can decide with confidence whether a 4 oven Aga is the right choice for your kitchen.
At John Wray Range Cookers we specialise in reconditioned and converted Aga cookers, so everything below is based on real installations and how people actually live and cook with them, not just brochure diagrams.
A 4 oven Aga is a cast-iron heat-storage cooker with:
In a traditional layout, a 4 oven Aga is effectively a 2 oven Aga with an additional hotcupboard section on the side. The right-hand part of the cooker carries the main high-temperature ovens; the left-hand “hotcupboard” section provides extra low-temperature capacity and warming.
On most 4 oven models the ovens are arranged in two columns:
The exact labels can vary slightly between generations and fuel types, but in most traditional 4 oven layouts the right-hand ovens handle the main cooking (roasting and simmering), and the left-hand hotcupboard provides the dedicated baking and warming ovens.
Compared with 2 oven and 3 oven Agas, a 4 oven Aga gives you significantly more capacity and more temperature zones ready at the same time, but it also needs more wall space and, on traditional always-on models, gives off more background heat.
A 4 oven Aga is designed so that each oven has a clear role, and the extra hotcupboard side gives you more flexibility for entertaining, batch cooking and keeping plates and dishes ready to serve.
The roasting oven is your main high-temperature oven. It is used for:
Roasts and joints of meat
Crispy roast potatoes and vegetables
Pies, pasties and savoury pastries
Lasagnes, gratins and similar dishes
Fast baked items such as pizzas and flatbreads
The top of the roasting oven is the fiercest area, with heat softening as you move lower. You can use this to your advantage – placing crackling and potatoes high up, and more delicate dishes lower down.
The baking oven sits at a moderate baking temperature and is ideal for:
Cakes and sponges
Biscuits and cookies
Traybakes and muffins
Bread, rolls and soda bread
Quiches, flans and general “everyday oven” cooking
Unlike a 2 oven Aga, you do not need to tame the roasting oven with a cold plain shelf to bake; the baking oven is set up for this kind of cooking from the start.
The simmering or slow-cooking oven runs at a much lower temperature and is used for:
Slow stews and casseroles
Pulled meats and braises
Long-simmered soups and stocks
Meringues and heavy cakes
Keeping dishes warm without drying them out
This oven allows you to cook ahead and let dishes finish gently while you concentrate on other parts of the meal.
The fourth oven is typically a warming or plate-warming oven. It is kept at a lower heat again and is perfect for:
Warming plates before serving
Holding vegetables, sauces and side dishes at serving temperature
Very gentle drying, depending on model and setup
For busy meals, this extra low oven can make a significant difference to how calmly you can serve several courses or a large table.
On top of the cooker you still have the two classic hotplates under the lids:
The boiling plate, which is extremely hot and used for fast boiling, searing, stir-fries and getting pans up to temperature quickly
The simmering plate, which is gentler and used for sauces, porridge, eggs and general low-heat pan work
On some 4 oven models there is also a warming plate over the hotcupboard section. This is a useful place to rest cooked food and keep serving dishes warm before they go to the table.
You control the heat by moving pans between the hotplates, using lids up or down, and choosing which oven to use, rather than constantly adjusting gas burners. Once you are familiar with it, it is a straightforward and efficient way to cook.
As with all Agas, exact temperatures vary by model, fuel and setup, but a traditional 4 oven Aga is designed so that each oven sits in a different temperature band:
Roasting oven – hottest
Baking oven – moderate baking heat
Simmering / slow-cooking oven – low, gentle heat
Warming oven – very low heat for plates and holding food
Broadly, on many 4 oven Agas:
The roasting oven behaves like a hot conventional oven, often in the low-to-mid 200s °C near the top.
The baking oven sits in a moderate range suitable for most cakes and everyday baking.
The simmering or slow-cooking oven runs in a lower “slow cooker” range.
The warming oven runs lower again and is used for plates and gentle holding rather than active cooking.
Because the Aga is a heat-storage cooker, there is usually no digital display on traditional models. Most owners learn their oven by shelf position and timing rather than aiming for an exact thermostat reading.
For a fuller explanation of typical Aga oven temperatures and how to translate conventional recipes, see our main Aga oven temperature guide.
When a 4 oven Aga is converted to a modern electric system, you keep the four-oven layout (roasting, baking, simmering/slow-cooking and warming) but gain more precise control over the heat and timings.
In day-to-day use this usually means:
You can set modes or target temperatures (for example Roast, Bake, Simmer, Slow Cook or a specific °C) for each oven.
Each oven continues to play its usual role, but you can choose when it is on, how hot it runs and, on some systems, schedule it to be ready when you need it.
The hotplates still provide boiling and simmering zones, but you can turn them up, down or off completely when you are not cooking.
To compare the electric systems we use and choose the right conversion for your 4 oven Aga, see our Aga electric conversion page. For typical budgets and price bands by system and oven count, visit our Aga electric conversion cost page.
A 4 oven Aga is significantly wider than a 2 or 3 oven model. It is designed for kitchens with more wall space and generally suits larger rooms or chimney breasts.
As a guide, many traditional and modern 4 oven cast-iron Agas are around 1487 mm wide, about 851 mm high to the hob, and roughly around 680 mm deep, excluding the handrail and any rear clearance. For exact figures for each model, please see our Aga dimensions guide.
In most kitchens you need to check:
The clear width on the chosen wall or chimney breast – including any nibs, pipes or boxing that reduce usable space
That there is enough depth so the cooker does not project awkwardly beyond the cabinet fronts or into a walkway
That doors, drawers, walkways and islands still work comfortably once the cooker is in place
Clearances to walls, combustibles and any flue or flue-less requirements depend on the specific model and fuel or conversion system. All the detailed figures – widths, heights, depths, lid clearances and suggested recess sizes for every main Aga size – are set out on our page.
If you are unsure, measure your space, compare it with the figures there, and then send us your measurements and a couple of photos so we can confirm whether a 4 oven Aga will fit comfortably and safely.
4 oven Agas have been built in a range of fuel types and control systems over the years. On the reconditioned market you will typically see:
Traditional oil-fired or gas-fired 4 oven Agas running as always-on heat-storage cookers
Night-storage or 13-amp electric 4 oven Agas, storing heat and providing four cast-iron ovens and two hotplates
Factory electric 4 oven Agas with modern controls and, on some models, extra hob options
Reconditioned 4 oven Agas converted to modern electric systems, with separate control over each oven and hotplate
Modern electric and conversion systems can offer:
Faster warm-up and cool-down from slumber or ECO modes
Independent control of ovens and hotplates
Programmable timers and, on some systems, app or remote control
The ability to reduce or switch off background heat in summer
Potential running-cost savings compared with older always-on oil or gas models if you do not need 24-hour heat
If you already own a tired or older 4 oven Aga, you may not need to replace it. In many cases we can strip it down, re-enamel the panels, renew worn parts and rebuild it so it looks and behaves like a new cooker. You can read more about what is involved on our Aga refurbishment page, and if you are weighing refurbishment against buying a different cooker, our Aga running costs guide explains typical costs and what is included.
If your main concern is ongoing bills rather than appearance, our guide explains how different fuel types and modern electric conversion systems compare in day-to-day use.
When you are deciding between the larger Aga sizes, the main choice is often between a 4 oven and a 5 oven model.
A 4 oven Aga typically gives you:
A 5 oven Aga usually adds an additional hotcupboard or extra low-temperature oven compartment on top of the four main ovens. This can provide more gentle heat for slow cooking, plate warming and drying, and tends to be chosen for very large kitchens or for people who regularly cook for bigger groups.
A 4 oven model is often the better fit if:
If you are still deciding between all the Aga sizes, you can also look at our main Which Aga cooker should you choose guide for a full overview.
A 4 oven Aga is usually chosen by households that cook a lot and have the space to enjoy a larger cooker as a focal point in the kitchen.
It is often the best choice when:
If several of these points sound familiar, there is a good chance a 4 oven Aga will give you the combination of capacity, flexibility and presence you are looking for.
