“George from Thames Boilers came to install a brand new boiler in my property. Our previous boiler was 21 years old and beyond repair. George went through all the different options available to us, understood our needs and we settled on our new boiler. During installation he explained in detail what he was doing and what he’d be doing next. He was exceptionally clean and tidy throughout the entire installation. He was professional, friendly, courteous, reliable, trustworthy and efficient. I would wholeheartedly recommend Thames Boilers to everyone.”

Vaillant
Vaillant are one of the most popular boiler manufacturers in the UK. They’re a German firm, based in Remscheid, Germany since 1874.
Worcester Bosch
Worcester Bosch are probably the best known boiler brand in the country. Although now owned by the massive European brand, Bosch, Worcester boilers are still very much a British company. Their boilers are still made in Warndon in Worcester.


Viessmann
Viessmann is the greatest boiler manufacturer you’ve never heard of. However, don’t let that stop you considering one. Viessmann are huge in Europe and, like their competitors Vaillant, they’re German and have been around for over 100 years.
Baxi
Baxi Boilers are another well established British boiler manufacturer, founded in the industrial revolution by Richard Baxendale, an iron founder, who began the Baxendale Company in 1866, based in Preston in Lancashire. Today, Baxi also makes boilers under the Main and Potterton brands. We usually recommend Baxi boilers as the least disruptive replacement to some heat-only boilers – and their Main brand for people who are on a budget.
