What Our Customers Say
”George at Thames boilers has been great. Have used him on a couple of occasions and was always prompt , efficient and very friendly. He was even great with my nosy cat trying to get in his way. Had a hiccup with our new thermostat after he first visited and he immediately came within a few hours to fix it for us. Great service”
–M Hunter
”George was fast, clean, professional and did a great job installing our new boiler. He really knew his stuff and did the job with no hassle. Im only using him for this type of work from now on!”
-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.”
-Jonathan Freegard RIBA
Customers In Stonebridge Like These Boilers

Vaillant Boilers
Vaillant are one of the most popular boiler makes in the UK. Vaillant were arguably the first company to make a “combi” boiler back in the early 60’s. So they’re very well established.
Worcester Bosch Boilers
Worcester Bosch are one of the best known boiler makes in the country. Like Vaillant and Viessmann boilers, Worcester Bosch have won lots of Which? Best Buy awards.


Viessmann Boilers
Viessmann is the greatest boiler manufacturer you’ve never heard of. We love Viessmann here at Thames Boilers because they’re as well built as (if not better) than Vaillant and Worcester Bosch, however 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 Boilers
Baxi Boilers are another great British boiler manufacturer, whose roots go back to Richard Baxendale, an iron founder, who started the Baxendale Company in 1866, based in Preston in Lancashire. Today, Baxi also makes boilers under the Main and Potterton brands. We usually recommend Baxi boilers as the least disruptive replacement for some heat-only boilers – and their Main brand for people who want to keep costs down.

Common Questions From Our Stonebridge Customers​
Generally, if you‘ve got one bathroom as well as good water pressure at your kitchen tap or outdoors tap, a combination boiler is generally the very best option.
If you‘ve got over one bathroom in your home, a conventional, also called a “heat only” boiler (or even a system boiler) with a hot water tank would be the most effective option.
No. For existing residences, if you have to change your gas boiler from 2035 onwards, you won’t be allowed to replace it with another gas boiler. According to current government plans, you would have to install a Hydrogen boiler or a heat pump. However, if your gas boiler is operating in 2035, you won’t be required to do anything till it needs to be replaced, such as if it’s broken down & irreparable.
It can vary hugely depending upon what you need.
Yet as a rough estimate, to take your old boiler out & put a brand-new one in the exact same location varies from about ₤1800 to ₤3000.
And remove an old kind of heating system with a hot water tank {and} fit a combi boiler costs between about ₤3000 and ₤5000.
If you need other work carried out at the same time, such as a power flush, a new gas pipeline, or brand-new radiators, this will contribute to the estimated costs.
If you‘ve only got one bathroom as well as good water mains pressure, yes.
If you‘ve 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 several kinds of clever thermostats that can link to the net so you can control your boiler from your phone. Some brands people go with are Nest, Honeywell, Tado, as well as Hive.
