–Karen Mansfield

-Axelle Young
“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
Gravesend's Most Popular Boilers

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


Viessmann
Viessmann are the greatest boiler manufacturer you’ve never heard of. We’re big fans of Viessmann here at Thames Boilers because they’re as well built as (if not better) than Vaillant and Worcester Bosch, but their prices are a little lower. This makes Viessmann fantastic value – and Which? magazine agrees, giving Viessmann several ”Best Buy” awards in recent years.
Baxi
Baxi is another well established British boiler manufacturer, whose roots go back to Richard Baxendale, an iron founder, who began the Baxendale Company 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 conventional boilers – and their Main brand for people who are on a budget.

Frequently Asked Questions​
Generally, if you‘ve got one bathroom as well as good pressure at your kitchen tap or outdoors tap, a combi boiler is generally the best option.
If you‘ve got more than one bathroom in your home, then a conventional, also called a “heat only” boiler (and even a system boiler) with a hot water tank could be the most effective option for you.
No. For existing homes, if you have to replace your boiler from 2035 onwards, you will not be allowed to replace it with another gas boiler.

However, if your gas boiler is operating in 2035, you will not need to do anything until it needs to be changed, such as if it’s broken down & beyond repair.
It can vary extremely depending on what you require.
But as a rough guide, to take your old boiler out & put a brand-new one in the exact same location varies from about ₤1800 to ₤3000.
