What Our Customers Say
”Polite, professional and very efficient! Would recommend our installer George.”
-Linda Mulley
“Excellent service very friendly and professional would recommend”
-Mike Phillips
“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.”
-David Herrington
Popular Boilers In Brockley

Vaillant Boilers
Vaillant are one of the best known boiler manufacturers in the UK. Vaillant were arguably the first company to make a “combi”also known as a “combination” boiler back in the early 1960’s. So they’re very well established.
Worcester Bosch Boilers
Worcester Bosch are probably the best known boiler brand in the UK. Although they’re now owned by the big German brand, Bosch, Worcester boilers are still very much a British company. Its boilers are still made in Warndon in Worcester, in the United Kingdom.


Viessmann Boilers
Viessmann is the best boiler brand you’ve never heard of. However, don’t let that stop you considering one. Viessmann are a massive brand in Europe and, like Vaillant, they’re German and have been around for over 100 years.
Baxi Boilers
Baxi Boilers are another well established British heating brand, founded in the industrial revolution by Richard Baxendale, an iron founder, who started the Baxendale Company (now Baxi) in 1866, based in Preston in Lancashire. These days, Baxi also makes well known Main and Potterton boiler brands, as part of the Baxi group. We recommend Baxi boilers as the least disruptive replacement to some heat-only boilers – and their Main brand for people who want to keep costs down.
