Corporate History

In 1962 Worcester Engineering was founded to develop domestic oil-fired boilers. In 1987 the company was renamed Worcester Heat Systems to reflect its growth and acquisitions. In 1992, the company was acquired by the Bosch Group. The company is now known as Worcester-Bosch, and has manufacturing facilities in Worcester and Clay Cross in Derbyshire, UK, and a Training Academy in Worcester, UK.

Product Lines

The company’s boilers, gas and oil-fired, are sold under the Greenstar brand name. These include internal, external, floor standing and wall mount units, as well as combi boilers and compact units that can fit inside a kitchen cupboard. All Worcester boilers run at 90 percent efficiency or higher, which for many translates to an Energy Savings Trust (EST) seal of approval. Many of the company’s boilers can integrate with solar panels.


Worchester-Bosch offers a 2 year standard warranty on parts for most of its boilers. Gas-fired boilers feature a 10-year primary heat exchanger warranty, while oil-fired boilers are covered by a 5-year primary heat exchanger warranty and a 10-year secondary heat exchanger warranty. The company offers extended warranties as well.

Worcester Boiler Reviews

"I will be writing about how well my boiler works throughout my house. I must say it works better then the last couple places we"

5.0 rating
Very Satisfied

We have recently gotten this boiler since the move to this house, so it has been about 3 months. It has worked amazingly for us. There has yet to be any problems unlike with our last model which came with the house originally. It had leaks and cracks, which were going to cost us too much to repair to the point where we thought it would be better to just buy ourselves a new one. I must say, the one we currently have is amazing and I have recommended it to my family and friends. It just took a while to get here.

"Review of my boiler"

5.0 rating
Very Satisfied

I have been using this boiler since 2007. I am very satisfied with its quality. it's very convenient and of a good standard. I like it because of its brand's standard. One thing that I dislike about my boiler is that it's too small our family. I have never had to repair or replace it, because it's working very efficiently. I would recommend that my friends buy a Worcester brand boiler.
