-James Quinn
”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.”

Kemsley's Favourite Boilers

Vaillant Boilers
Vaillant are one of the best known boiler brands 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 probably the best known boiler brand in the UK. Like their closest rivals Vaillant and Viessmann, Worcester boilers 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 their build quality is as good as (if not better) than Vaillant or Worcester Bosch, but their prices are a little lower. This makes Viessmann fantastic value – and Which? agrees, giving Viessmann several Best Buy awards in recent years.
Baxi Boilers
Baxi Boilers are another great British boiler brand, whose roots go back to Richard Baxendale, an iron founder, who started the Baxendale Company in 1866, based in Preston in Lancashire. These days, Baxi also makes boilers under the Main and Potterton brands. We recommend Baxi boilers as the least disruptive replacement for some heat-only boilers – and their Main boiler brand for people who want to keep costs down.
