Brand History and Heritage
When you're exploring boiler brands, Worcester Bosch's rich heritage stands out as one of Britain's most trusted names in heating. Founded in 1962 by Cecil Duckworth at The Old Vinegar Works in Worcester, the company started with a focused mission on oil-fired central heating systems.
You'll find their growth story quite impressive. After moving to larger premises in Diglis in 1968, they went public on the London Stock Market in 1986. The company really hit its stride in the 1980s when they pioneered combination boilers in the UK.
A major turning point came in 1992 when German industrial giant Robert Bosch GmbH acquired the company, creating Worcester Bosch as it's recognised today. Since then, they've gone from strength to strength, receiving a Royal Warrant in 2009 and manufacturing their 50,000th boiler in 2018.
Their innovation timeline reads like a who's who of heating technology, from the Greenstar series in 2001 to their modern eco-friendly solutions. Our comprehensive Worcester Bosch Boilers guide covers everything you need to know about their complete range of heating solutions.
