Worcester Bosch, we take pride in being one of the world’s leading names in heating innovation, with a rich lineage of engineering excellence and customer satisfaction. Our brand has become synonymous with high-end technology, superior quality, and assured traditional engineering. In this article, we will delve into the history of Worcester Bosch and how our brand continues to create top-of-the-line boilers that meet the needs of our customers.

Brand Origin and Development

The Worcester Engineering Co Ltd was founded in 1962 by Engineer Cecil Duckworth at the Old Vinegar Works in St. Martins Gate, Worcester. By the mid-1960s, Worcester Engineering had rapidly cemented itself as a market leader in oil-fueled heating in the UK. The Worcester Firefly model proved an early success for the brand.

In 1970, Worcester outsourced the manufacture of some key boilers to the Japanese company Sunwave. As the 1970s progressed, and with the introduction of the soon-to-be revolutionary combi boiler in the UK, the at one time 95% monopoly that oil held in home heating dwindled, and the intrigue in gas as the most prevalent fuel source grew.

The 1980s was a decade of highs and lows for Worcester. The company managed to resurrect itself from a factory fire, manufacturing boiler units just three weeks later and rebuilding the factory 104 days after the initially destructive blaze. Worcester then overcame bye-law obstructions from the water authorities to continue to develop their latest cost-efficient and space-saving combi boiler concept designs to provide both heating and hot water.

In 1986, in an attempt to raise equity capital, Worcester was floated on the London Stockmarket with share prices soaring from an initial £1 to £13 in just eighteen months. In 1987 Worcester Engineering was renamed Worcester Heat Systems.

The 1990s saw Worcester open new advanced large-scale production and training facilities, the centrepiece of which was the new company HQ at Warndon on the edge of Worcester. In 1992, a significant moment for the brand, after two years of negotiations, Worcester was sold to Robert Bosch GmbH, joining the Bosch Group. Worcester would now be regarded as a key element of Europe’s most successful domestic heating company.

Modern Era of Worcester Bosch Boilers

The 2000s saw Worcester Bosch focus on environmental concerns, creating the award-winning Environment 2000 initiative. This led to the designing and production of eco-conscious Worcester boilers with a trope of energy efficiency, as well as affordable pricing. The highly successful Greenstar range was also launched, winning several industry awards from CORGI and OFTEC.

The 2010s were a highly successful decade for Worcester Bosch, with great commercial success after heavy investment in consumer advertising to promote their customer-centric, high-quality boilers. Worcester Bosch received many accolades within the decade, including Which? Awards for the Greenstar boiler series and commendations for their outstanding customer service. The 2010s were also a decade for celebration and reflection as Worcester celebrated 50 years, Bosch celebrated 150 years, and in 2018 Worcester’s 50,000th boiler was manufactured at the clay cross site.
