Comments From Our Customers
”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 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
Popular Boilers In Sheerness

Vaillant Boilers
Vaillant are one of the best known boiler brands in the UK. Vaillant are a German company, with their headquarters in Remscheid, Germany since 1874.
Worcester Bosch Boilers
Worcester Bosch are among the best known boiler brands in the UK. Although they’re now owned by the big German brand, Bosch, Worcester boilers are still very much a British company. Worcester Bosch’s boilers are still made in Warndon in Worcester, in the UK.


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

Most Asked Questions From Our Sheerness Customers​
Generally, if you have got one bathroom and excellent water pressure at your kitchen tap or outdoors tap, a combination boiler is generally the very best choice for most people.
If you have 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 choice for you.
No. For existing residences, if you need to change your boiler from 2035 onwards, you will not be able to replace it with another gas boiler. Going by current government plans, you would need to install a Hydrogen boiler or a heat pump. Nevertheless, if your gas boiler is working in 2035, you will not need to do anything until it needs to be replaced, such as if it’s broken down and irreparable.
It can vary extremely depending upon what you need.
But as a rough estimate, to take your old boiler out and put a brand-new one in the exact same place varies from roughly ₤1800 to ₤3000.
And take out an old kind of heating system with a hot water cylinder {and} put in a combi boiler costs between roughly ₤3000 to ₤5000.
If you need various other work carried out at the same time, such as a power flush, a new gas pipeline, or new radiators, this will certainly add to the estimated price.
If you have only got 1 bathroom and excellent water pressure, then yes.
If you have got more than 1 bathroom or poor water 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 connect to the internet so you can manage your boiler from your phone. Some brand names people go for are Nest, Honeywell, Tado, and Hive.
