The company was founded by Cecil Duckworth in 1962 as Worcester Engineering Co Ltd, based at the Old Vinegar works in Worcester. Worcester's early success is attributed to the pioneering of combination boilers in the UK,^[3] further successful performance in the UK heating market led to the expansion and relocation of the factory to its current headquarters in Warndon in 1990.^[4]

Continued growth was followed by the acquisition by Robert Bosch GmbH in 1992, with the company changing its name to 'Worcester, Bosch Group'. As part of Bosch's heating technology subsidiary, Worcester is a brand of Bosch Thermotechnology Ltd, the collective name that refers to Worcester, Bosch Group and Buderus (acquired by Bosch in 2003).^[5]

Whilst Worcester's origins lie in oil and gas boilers, recent years have seen the company champion renewable technologies such as solar water heating, ground source and air source heat pumps. The company runs schemes such as the Environment 2020 awards to reward and promote energy efficiency and reinforce their commitment to being an "environmentally responsible manufacturer".^[6]

Worcester has been awarded the royal warrant by the Queen for supplying hot water products to the royal family.^[7]

Worcester Bosch Group were a founding sponsor of the Upton Blues Festival, but in 2009 reluctantly pulled out.^[8]

The company has strong connections to the Worcester Warriors Rugby club through Chairman and founder Cecil Duckworth CBE, and that was renewed in 2010 when Worcester, Bosch Group was named as the Warriors new shirt sponsor up to the 2012-13 season.^[9]

Worcester's product portfolio covers seven technologies:

• Boilers fired by natural gas, heating oil and liquefied petroleum gas
• Solar water heating
• Geothermal heat pumps
• Air to air heat pumps
• Air to water heat pumps

Worcester's gas, oil and LPG ranges consist of regular boilers, combination boilers and system boilers; these are wall-hung, floor-standing or externally sited.

Worcester's solar water heating range was released in 2005, with the ground source heat pump range being released in 2007 and the air source heat pump range being released in 2008.^[10]

Worcester operates a loyalty scheme known as the Worcester Accredited Installer scheme. Worcester Accredited Installers "specialise in Worcester products and can offer extended warranties" and benefit from features such as the online 'Find an Installer' search.^[11] Worcester Accredited Installers are experienced in fitting Worcester products but are not employed by Worcester.^[12] Worcester specifies that all members of the Worcester Accredited Installer scheme are Gas Safe Registered.

It has been announced in the local and national press that the company has applied for planning permission to relocate its Warndon headquarters to a new site near junction 6 of the M5.^[13] This land is part of the Green Belt.

An interview with Paul Middlebrough, leader of the Wychavon District Council in the Worcester News provided some support for the proposed move; "Strategically, Wychavon recognises the absolute necessity to retain Bosch and formulate its expansion in the Worcester area. In this difficult and probably deteriorating time, the fact that Bosch are going to expand is good for everybody. The proposal will provide opportunities for more employees to move into a prime location, which places us in a good position to promote jobs for local people as the economy recovers."^[14]

In May 2018, a serious data breach inadvertently revealed the home addresses of “tens of thousands” of Worcester customers.^[15]
