Worcester Bosch

Founded in 1962, Worcester Bosch has a commendable reputation within the domestic heating industry. Striving to produce high-quality, energy-efficient boiler systems, the brand’s commitment to manufacturing products that could meet a variety of central heating needs has led to them becoming a popular household name.



Regarded as a pioneer of the combi boiler, Vaillant has maintained an esteemed reputation within the industry for over 140 years. Aiming to provide homeowners with reliable and energy-efficient heating solutions, this brand designs their boilers with quality, performance and efficiency in mind.


Product range


Both brands manufacture a range of different boilers, including combi, heat-only (conventional) and system boilers. For example, Worcester Bosch is recognised for its Greenstar i series of combi boilers and its Greenstar Ri range of heat-only boilers. They have also recently released a new, innovative range of boilers : the Greenstar 8000 Lifestyle boilers (consisting of all three types of boiler systems).

Vaillant also has a range of A-rated boiler systems available, such as the EcoTec Plus range of combi boilers, the EcoFit Pure range of heat-only boilers and the EcoTec Exclusive system boiler range.
