What Do 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
“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
People In Greenwich Choose These Boiler Brands

Vaillant Boilers
Vaillant are one of the best known boiler brands in the UK. Vaillant are thought to be one of the best boiler brands on the market, winning Which? Best Buy awards on a every year.
Worcester Bosch Boilers
Worcester Bosch are among the best known boiler makes in the country. Like Vaillant and Viessmann boilers, Worcester boilers have recieved lots of Which? Best Buy awards.


Viessmann Boilers
Viessmann are the best boiler make 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 and Worcester Bosch, however their prices are a little lower. This makes them great value – and Which? agrees, giving Viessmann boilers several ”Best Buy” awards in recent years.
Baxi Boilers
Baxi Boilers are another great British heating make, who can trace their roots back to Richard Baxendale, an iron founder, who started the Baxendale Company in 1866, based in Preston in Lancashire. Today, 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 to some conventional boilers – and their Main boiler brand for people who want to keep costs down.

Most Asked Questions From Our Greenwich Customers​
As a rule, if you‘ve got one bathroom and great water pressure at your kitchen tap or outside tap, a combination central heating boiler is normally the best option for most people.
If you‘ve got over one bathroom, then a conventional central heating boiler (and even a system central heating boiler) with a hot water cylinder would be the most effective option for you.
No. For existing residences, if you need to replace your gas boiler from 2035 onwards, you won’t be allowed to replace it with another gas central heating boiler. Going by current government plans, you would need to fit a Hydrogen boiler or a heat pump. Nonetheless, if your gas central heating boiler is operating in 2035, you won’t be required to do anything up until it needs to be replaced, such as if it’s broken down and beyond repair.
It can differ widely depending on what you need.
But as a rough estimate, to take your old central heating boiler out and put a new one in the exact same place varies from about ₤1800 to ₤3000.
And take out an old sort of heating system with a hot water tank {and} put in a combi central heating 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 pipe, or brand-new radiators, this will add to the estimated price.
If you‘ve only got 1 bathroom and great water mains pressure, then yes.
If you‘ve got more than 1 bathroom or poor water mains pressure, then no{, you should look at a conventional boiler or a system boiler}.
