“Excellent service very friendly and professional would recommend”
-Mike Phillips
”Thames Boilers have just carried out a boiler replacement for me. They quoted promptly with a competitive rate and carried out the work neatly, thoroughly and efficiently to a high standard of workmanship. Engineer George Lane was courteous, explained in advance what he was doing and when he would do it, cleared everything away and left things in a tidy state. I have no hesitation in recommending Thames Boilers.”

Popular Boilers In Peckham, Southwark

Vaillant Boilers
Vaillant are one of the best known boiler manufacturers in the UK. Vaillant are considered by heating engineers to be one of the best boiler brands on the market, winning Which? Best Buy awards on a every year.
Worcester Bosch Boilers
Worcester Bosch are one of the best known boiler brands in the UK. Like Vaillant and Viessmann boilers, Worcester Bosch have recieved several Which? Best Buy awards.


Viessmann Boilers
Viessmann are the greatest boiler brand you’ve never heard of. We love Viessmann here at Thames Boilers because they’re as well built as (if not better) than Vaillant and Worcester Bosch, however their prices are a little lower. This makes Viessmann fantastic value – and Which? magazine agree, giving Viessmann boilers several ”Best Buy” awards in recent years.
Baxi Boilers
Baxi is another great British heating brand, who can trace their roots back to Richard Baxendale, an iron founder, who started the Baxendale Company (now Baxi) in 1866, based in Preston in Lancashire. Today, Baxi also make well known Main and Potterton boiler brands, as part of the Baxi group. We recommend Baxi boilers as the least disruptive replacement for some heat-only boilers – and their Main brand for people who are on a budget.
