AGA cookers are made by AGA Rangemaster Limited, a British manufacturer headquartered in Leamington Spa, England.
The brand is known for its cast iron heat storage cookers, which stay on continuously and use radiant heat instead of a fan to cook food.
AGA Rangemaster is now part of Composition Brands, formerly Middleby Residential Kitchen, a luxury kitchen brand portfolio majority owned by investment firm 26North Partners.
Knowing who actually builds an AGA cooker helps buyers understand the brand’s manufacturing standards and ongoing parts and service support.
This article covers who owns AGA, where its cookers are manufactured, the brand’s ownership history, and answers to common questions about the company.
So let’s get started.

Who Makes AGA Cookers?
AGA cookers are made by AGA Rangemaster Limited, though the design itself dates back to 1922, when Swedish Nobel Prize winning physicist Gustaf Dalen invented the original cast iron range.
The name AGA stands for Aktiebolaget Gas Accumulator, the Swedish company where Dalen served as chief engineer, and the cooker’s heat storage design has remained largely unchanged for a century.
The cooker was introduced to the United Kingdom in 1929 and has been manufactured there under license since the early 1930s.
Who Owns AGA Today?
AGA Rangemaster Limited was acquired by the American Middleby Corporation in September 2015 for roughly 129 million pounds.
In February 2026, Middleby completed a transaction selling a 51 percent controlling stake in its residential kitchen business, including AGA, to an affiliate of investment firm 26North Partners.
Middleby retained a 49 percent non-controlling interest in that joint venture, which now operates under the name Composition Brands and also owns Viking, La Cornue, Rangemaster, and Marvel.
Where Are AGA Cookers Made?
AGA’s 90, 100, and 110 centimeter range cookers are still manufactured at the company’s factory in Leamington Spa, Warwickshire, where Rangemaster cookers have been built since 1830.
The cast iron parts were historically cast at the Coalbrookdale foundry, though the new American owners closed that site in November 2017.
The North American subsidiary, AGA Marvel, also distributes AGA Rangemaster cooking products under the AGA brand in the United States while separately manufacturing its own Marvel refrigeration line.
AGA vs La Cornue: How Do the Two British and French Brands Compare?
AGA and La Cornue now sit under the same Composition Brands ownership but represent two distinct national cooking traditions.
AGA’s cast iron heat storage design runs continuously and is built around the English country kitchen tradition, while La Cornue’s vaulted convection ranges are handcrafted to order in France with thousands of color and trim combinations.
Buyers drawn to a constant always on cooking experience tend to choose AGA, while those wanting a fully customizable French heirloom piece typically choose La Cornue.
Why Are AGA Cookers So Popular in the UK?
AGA cookers became a fixture of medium to large British country homes through the mid and late twentieth century, popular enough to inspire the term AGA saga for a genre of fiction set in upper middle class English society.
The brand’s appeal comes from its constant radiant warmth, which heats the kitchen as well as the food, though that always on design also means higher energy use than a standard oven.
Buyers comparing other heritage kitchen brands can also see how AGA’s portfolio compares to Monogram and JennAir, two other long established luxury appliance names.
