Comments From Our Customers
”Polite, professional and very efficient! Would recommend our installer George.”
-Linda Mulley
”George replaced our boiler recently. He was really friendly, reliable and fair with pricing. Would definitely recommend and will be booking in for annual boiler services without a doubt.”
-Emma T
”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.”
-Jonathan Freegard RIBA
Customers In Rainham Like These Boilers

Vaillant
Vaillant are one of the best known boiler makes in the UK. Vaillant are a German firm, with their headquarters in Remscheid, Germany since 1874.
Worcester Bosch
Worcester Bosch are among the best known boiler manufacturers in the country. Like Vaillant and Viessmann boilers, Worcester boilers have recieved lots of Which? Best Buy awards.


Viessmann
Viessmann are the greatest boiler make you’ve never heard of. We’re big fans of Viessmann 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 great value – and Which? magazine agrees, giving Viessmann boilers several Best Buy awards in recent years.
Baxi
Baxi is another well established British heating make, who can trace their roots back to 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 recommend Baxi boilers as the least disruptive replacement to some heat-only boilers – and their Main boiler brand for people who are on a budget.

Frequently Asked Questions​
Generally, if you‘ve got one bathroom and excellent water pressure at your kitchen tap or outside tap, a combination central heating boiler is normally the very best choice for most people.
If you‘ve got over one bathroom, then a conventional, also called a “heat only” central heating boiler (or even a system central heating boiler) with a hot water cylinder would be the most effective choice for you.
No. For existing residences, if you need to change your central heating boiler from 2035 onwards, you will not be allowed to put in another gas central heating boiler.

It can vary widely depending on what you require.
But as a rough estimate, to take your old central heating boiler out and put a new one in the exact same location ranges from roughly ₤1800 to ₤3000.
