”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.”

Customers In Otford Like These Boilers

Vaillant Boilers
Vaillant are one of the most popular boiler brands in the UK. Vaillant are thought to be one of the best boiler manufacturer’s around, winning Which? Best Buy awards on a regular basis.
Worcester Bosch Boilers
Worcester Bosch are one of the best known boiler brands in the UK. Like their closest competitors Vaillant and Viessmann, Worcester boilers have won lots of Which? Best Buy awards.


Viessmann Boilers
Viessmann are the greatest boiler brand you’ve never heard of. We love Viessmann here at Thames Boilers because their build quality is as good as (if not better) than Vaillant or Worcester Bosch, however their prices are a little lower. This makes Viessmann fantastic value – and Which? agrees, giving Viessmann several ”Best Buy” awards in recent years.
Baxi Boilers
Baxi is another well established British boiler brand, whose roots go back to Richard Baxendale, an iron founder, who started the Baxendale Company (now Baxi) in 1866, based in Preston in Lancashire. These days, Baxi also makes boilers under the Main and Potterton brands. We usually recommend Baxi boilers as the least disruptive replacement to some conventional boilers – and their Main brand for people who want to keep costs down.

Most Asked Questions From Our Otford Customers
As a rule, if you‘ve got one bathroom and excellent pressure at your kitchen tap or outside tap, a combination central heating boiler is usually the best option.
If you‘ve got over one bathroom, then a conventional, also called a “heat only” central heating boiler (or even a system central heating boiler) with a hot water cylinder would be the best option.
No. For existing houses, if you have to replace your boiler from 2035 onwards, you will not be able to put in another gas central heating boiler. Going by current government plans, you would have to install a Hydrogen boiler or a heat pump. However, if your gas central heating boiler is operating 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 widely depending on what you need.
However as a rough estimate, to take your old central heating boiler out and put a brand-new one in the same place varies from about ₤1800 to ₤3000.
And remove an old kind of gas boiler with a hot water storage tank {and} fit a combi central heating boiler costs between about ₤3000 and ₤5000.
If you need various other jobs carried out at the same time, such as a power flush, a new gas pipe, or new radiators, this will add to the estimated price.
If you‘ve only got one bathroom and excellent water pressure, then yes.
If you‘ve got more than one bathroom or bad water pressure, then no{, you should look at a conventional boiler or a system boiler}.
Yes. There are several types of clever thermostats that can link to the web so you can regulate your central heating boiler from your phone. Some brands people go with are Nest, Honeywell, Tado, and Hive.
