AGA Rangemaster Limited[1] is a British manufacturer of range cookers, kitchen appliances, and interior furnishings owned by Middleby Corporation[2] in September 2015 after it received a takeover approach from Whirlpool.

[5][6] Glynwed, later Glynwed International, was formed in 1939 through the merger of "Glynn Brothers, Builders and Plumbers Merchants of Birmingham" (engineering and plumbing materials) with sister company "The Wednesbury Tube Company" (solid drawn copper tubes).

[8] However, Glynwed was acquired by Mueller Industries Inc. (USA) in 1997, and subsequently underwent major reorganisation in 2001, with the pipes business being sold to Etex Group for £786 million, and the remainder being renamed AGA Foodservice.

[10] Middleby Corporation acquired the group in 2015 for £129 million, closing the Coalbrookdale manufacturing plant in 2017.

[11][12][13] AGA and Rangemaster lead the portfolio of consumer brands which include Divertimenti, Falcon, Mercury, Fired Earth, Grange, Heartland, La Cornue, Leisure Sinks, Redfyre, Marvel, Rayburn and Stanley.
