What Do Our Customers Say?
“Excellent service, great value for money. Had new boiler fitted last year during pandemic, easy , smooth operation. This year had boiler serviced. Highly recommend George from Thames boilers.”
–Karen Mansfield
”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
“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
Popular Boilers In Maze Hill

Vaillant Boilers
Vaillant are one of the most popular boiler brands in the UK. Vaillant were arguably the first company to make a “combi”also known as a “combination” boiler back in the early 60’s. So they’re very well established.
Worcester Bosch Boilers
Worcester Bosch are probably the best known boiler brand in the country. Like their closest rivals Vaillant and Viessmann boilers, Worcester Bosch have recieved several Which? Best Buy awards.


Viessmann Boilers
Viessmann are the best 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 agree, giving Viessmann boilers several ”Best Buy” awards in recent years.
Baxi Boilers
Baxi is another great British boiler manufacturer, founded in the industrial revolution by Richard Baxendale, an iron founder, who started the Baxendale Company in 1866, based in Preston in Lancashire. These days, 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 to some conventional boilers – and their Main brand for people who want to keep costs down.

Common Questions From Our Maze Hill Customers​
As a rule, if you have got one bathroom and also great pressure at your kitchen tap or outside tap, a combi boiler is normally the best option for most people.
If you have got over one bathroom in your home, then a conventional boiler (and even a system boiler) with a hot water cylinder could be the best option for you.
No. For existing homes, if you have to change your boiler from 2035 onwards, you will not be allowed to put in another gas boiler. Going by current government plans, you would have to fit a Hydrogen boiler or a heat pump. Nevertheless, if your gas boiler is working in 2035, you will not need to do anything till it needs to be replaced, such as if it’s broken down and beyond repair.
It can differ extremely depending upon what you need.
However as a rough estimate, to take your old boiler out and put a brand-new one in the exact same location varies from about ₤1800 to ₤3000.
And remove an old kind of boiler with a hot water cylinder {and} put in a combi boiler costs between about ₤3000 to ₤5000.
If you need other work carried out at the same time, such as a power flush, a new gas pipe, or new radiators, this will contribute to the estimated costs.
If you have only got one bathroom and also great 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 a number of sorts of clever thermostats that can link to the internet so you can control your boiler from your phone. Some brands people choose are Nest, Honeywell, Tado, and also Hive.
