The Aga has long been the heart of British kitchens, a cast-iron icon that blends tradition, quality, and quiet confidence. Whether nestled in a cosy cottage or standing proud in a country kitchen, its enamelled finish and gentle warmth offer more than just cooking power, they define a way of life.
Often referred to as an Aga stove, oven or cooker, it’s a heat-storage range that works unlike any standard appliance. Instead of cycling on and off, an Aga maintains a steady, low-level heat, held within its heavy cast-iron body. Different zones are always at the ready for roasting, baking, simmering or boiling, with no need to adjust temperatures manually.
What makes the Aga truly special is how it cooks. Its radiant heat envelops food gently and evenly, preserving moisture and enhancing flavour in a way fan ovens simply can’t. From golden pastry to slow-cooked stews, the results are consistently rich and satisfying.
At John Wray Range Cookers, we specialise in restoring, converting, and refurbishing these classic cookers, helping a new generation enjoy their lasting charm, function and beauty.
The love for Aga goes far beyond cooking. Here’s what makes them special:
Unmatched Cooking Results: Even radiant heat delivers moist roasts, perfect pastry and slow-cooked stews.
Always Ready: No preheating needed. Just lift the lid or open the oven and begin.
Versatile Functionality: Warm plates, dry clothes, toast bread, boil kettles or just heat the room.
Quiet, Elegant Presence: With no fans or timers, an Aga adds peace and character to your kitchen.
Built to Last: Many Agas last over 50 years. With care or refurbishment, they can go on indefinitely.
Thinking of refreshing your older Aga instead of replacing it? Our Aga refurbishment services restore tired cookers to beautiful, like-new condition, inside and out. You can even choose a fresh colour. View our Aga refurbishment cost pages to learn more.
Unlike ordinary cookers that heat up on demand, the Aga range cooker is built on the principle of heat storage. It uses a single, slow-burning heat source to warm a heavy cast-iron core, which then gently radiates consistent heat into the ovens and hotplates. This simple yet ingenious system creates a unique, always-ready cooker that operates silently and reliably, often for decades.
Depending on the model, the core is heated by:
a vaporising oil burner
a gas burner
a solid fuel firebox
or, in converted Agas, an electric element
This source runs continuously at a low level, feeding heat into the cooker’s thermal mass.
The cast-iron body absorbs and stores heat, then releases it slowly through radiant and convective heat. This method ensures food cooks evenly and stays moist, with no fan, no noise, and no temperature fluctuations.
Each oven is always at a stable preset temperature:
Roasting oven (approx. 220–240°C)
Baking oven (approx. 180–200°C)
Simmering oven (approx. 120–140°C)
Warming oven (approx. 50–100°C)
You choose the oven for the task, rather than adjusting the heat.
Two cast-iron hotplates, boiling and simmering, sit atop the cooker, instantly ready under insulated lids. They’re perfect for frying, boiling, or warming dishes.
Always on, always ready. With an Aga, there’s no preheating. It holds its temperature even after opening the door, allowing multiple dishes to cook simultaneously.
Many owners now choose to convert their Aga to electric. This keeps the traditional cooking method, but adds energy efficiency and zoned control. Learn more about our Aga electric conversions.
At John Wray, we specialise in converting traditional Agas to electric using trusted, high-performance systems that retain the soul of your cooker while adding modern benefits.
Popular options include:
eControl Series X‑Squared – a premium solution offering precise, independent control over each oven and hotplate, with rapid heat-up and digital programmability.
ElectricKit Advanced – an efficient upgrade ideal for everyday use. Offers modular control, improved insulation, and no need for a flue or ventilation.
With either system, you can:
Cut running costs by powering only what you need
Enjoy silent, clean operation with no fuel storage
Eliminate the need for flue work or chimney access
Maintain the timeless look and cooking style of your Aga

One of the most frequently asked questions is:
“What fuel does an Aga use?”
The answer depends on the age and model of the cooker. Here’s a quick guide:
These were the original Aga models, designed in the 1920s. They burned solid fuel like coke or anthracite and had to be manually refuelled and de-ashed. These Agas are rare today, and most have been converted to run on oil, gas or electricity.
Oil Agas became popular in rural areas without mains gas. They are fed from an external oil tank and use a wick or pressure-jet burner. They’re dependable and powerful, but require regular servicing and the fuel cost can be high.
Clean-burning and convenient, gas Agas connect to mains supply or bottled gas. They offer better control and are generally cheaper to run than oil. Like oil models, they need a flue and occasional servicing.
Modern electric Agas or electric conversion kits are becoming the most popular option. Instead of a flame, electric elements heat the cooker – either as an always-on source or in a more flexible, controllable way. No flue is needed, and it’s ideal for modern homes or people looking to reduce running costs.
Many customers choose to convert their old gas Aga or oil Aga to electric with us. It cuts energy bills, removes the need for flue work, and offers zoned control, so you can turn individual ovens or hotplates on only when needed.
Aga cookers are available in multiple configurations to suit different households:
Ideal for compact kitchens. One roasting oven (hot) and one simmering oven (cooler), plus a boiling and simmering plate on the hob.
Adds a baking oven to the two-oven setup, offering more flexibility. Great for bakers or families who entertain often.
Includes roasting, baking, simmering and warming ovens, the ultimate setup for large households or cooks who want full versatility.
Most Agas we supply are reconditioned to order, based on these timeless models. During refurbishment, we can customise the colour and upgrade your cooker with a modern electric conversion for greater efficiency and control. Buy a reconditioned Aga or get in touch for expert, friendly advice tailored to your kitchen.
A new Aga can cost £10,000+. But a carefully rebuilt, older model can perform just as well or better. Here’s why more people are choosing reconditioned Agas:
Cost-effective: A reconditioned Aga is often less than half the price of new.
Built to last: Original models are engineered to endure decades, we just bring them back to life.
Eco-conscious: Reusing and refurbishing avoids unnecessary manufacturing and waste.
Customisable: Want a British Racing Green 4-oven oil Aga converted to electric? No problem. We’ll re-enamel, convert, and deliver it to your door.
Our team has restored hundreds of Agas for families across the UK. We can update yours with modern insulation, new burners, or fit a high-performance electric conversion. Full pricing breakdowns are available on our Reconditioned Aga prices and Aga refurbishment cost pages.
From oven configurations to fuel options and electric conversions, we’re here to help.
