“Excellent service very friendly and professional would recommend”
-Mike Phillips
“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.”

Popular Boilers In Rotherhithe

Vaillant
Vaillant are one of the most popular boiler brands in the UK. Vaillant are a German company, with their headquarters in Remscheid, Germany since 1874.
Worcester Bosch
Worcester Bosch are one of the best known boiler manufacturers in the country. Like their closest rivals Vaillant and Viessmann, Worcester boilers have won several Which? Best Buy awards.


Viessmann
Viessmann are the greatest boiler make 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 or Worcester Bosch, however their prices are a little lower. This makes them fantastic value – and Which? magazine agree, giving Viessmann several ”Best Buy” awards in recent years.
Baxi
Baxi Boilers are another great British boiler make, who can trace their roots back to Richard Baxendale, an iron founder, who began 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 usually recommend Baxi boilers as the least disruptive replacement to some conventional boilers – and their Main boiler brand for people who are on a budget.

Why Should You Install A New Modern Boiler? Here Are 6 Great Reasons
1. Slash Your Gas Bill
If you’ve got a very old boiler with a pilot light, old radiators, timer and thermostat, 45p of every £1 you spend on gas is completely wasted. Whichever way you look at it, that’s a terrible waste.
If you upgraded your boiler, controls – and perhaps even your radiators – at least 92p of every £1 you spent will be put to good use. Only 8p or less would be wasted. That’s a big saving – and if you add it up over a year, you could save over £250. On average, that’s an extra £25 per month in your pocket to spend on the nicer things in life, not gas.
2. Save Money On Boiler Breakdowns
3. More powerful showers and faster filling baths
4. No more running out of hot water
5. Free up more space in your home
6. Don’t worry about switching the heating on again.
