What Our Customers Say
”George replaced our old heating system with a combi boiler. Excellent service throughout, very neat and tidy and we’re very happy with the result! Much quieter boiler and hot water pressure is way better! Would highly recommend and will definitely use again”
-Luke Stratford-Higton
”George has been helping us for years on several properties and always is our go to man. He’s extremely polite and responsive, the quality of his work is always excellent. We definitely recommend him.”
-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
What Boilers Do We Recommend To Customers In Castle Hill?

Vaillant
Vaillant are one of the most popular boiler makes in the UK. They were arguably the first company to make a “combi”also known as a “combination” boiler back in the early 60’s. So they’re a well established company.
Worcester Bosch
Worcester Bosch are among the best known boiler makes in the country. If you want a really reliable boiler, but still want to support British manufacturing, then Worcester Bosch boilers are an excellent choice. Although they are some of the most expensive boilers we install.


Viessmann
Viessmann is the greatest boiler manufacturer you’ve never heard of. But don’t let that stop you considering one. Viessmann are huge in Europe and, like their competitors Vaillant, they’re German and have been around for over 100 years.
Baxi
Baxi Boilers are another great British boiler manufacturer, who can trace their roots back to Richard Baxendale, an iron founder, who started the Baxendale Company in 1866, based in Preston in Lancashire. These days, Baxi also make boilers under the Main and Potterton brands. We usually recommend Baxi boilers as the least disruptive replacement for some conventional boilers – and their Main boiler brand for people who want to keep costs down.

Common Questions From Our Castle Hill Customers​
As a rule, if you have one bathroom and good water pressure at your kitchen tap or outside tap, a combination central heating boiler is typically the best option for most people.
If you have got over one bathroom in your home, then a conventional central heating boiler (and even a system central heating boiler) with a hot water tank could be the most effective option for you.
No. For existing homes, if you need to change your gas boiler from 2035 onwards, you will not be allowed to replace it with another gas central heating boiler. According to current government plans, you would need to get a Hydrogen boiler or a heat pump. Nevertheless, if your gas central heating boiler is operating in 2035, you will not be required to do anything up until it needs to be replaced, such as if it’s broken down & irreparable.
It can differ widely depending on what you require.
But as a rough estimate, to take your old central heating boiler out & put a new one in the exact same location ranges from roughly ₤1800 to ₤3000.
And strip out an old type of boiler with a hot water storage tank {and} fit a combi central heating boiler costs between roughly ₤3000 and ₤5000.
If you require various other jobs carried out at the same time, such as a power flush, a new gas pipeline, or new radiators, this will contribute to the estimated costs.
If you have only got one bathroom and good water mains pressure, then yes.
If you have got more than one bathroom or inadequate water mains pressure, then no{, you should look at a conventional boiler or a system boiler}.
Yes. There are numerous types of clever thermostats that can link to the internet so you can manage your central heating boiler from your phone. Some brands customers go with are Nest, Honeywell, Tado, and Hive.
Yes, we cover the Castle Hill area as well as Dartford
