-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

Vaillant Boilers
Vaillant are one of the most popular boiler makes in the UK. They’re a German company, with their headquarters in Remscheid since 1874.
Worcester Bosch Boilers
Worcester Bosch are among the best known boiler brands in the country. Like Vaillant and Viessmann, Worcester boilers have won several Which? Best Buy awards.

Viessmann is the best boiler make you’ve never heard of. However, don’t let that put you off. Viessmann are huge in Europe and, like their rivals Vaillant, they’re German and have been around for over 100 years.
Baxi Boilers
Baxi is another well established British boiler make, who can trace their roots back to Richard Baxendale, an iron founder, who began the Baxendale Company (now Baxi) in 1866, based in Preston in Lancashire. Today, Baxi also make boilers under the Main and Potterton brands. We usually 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.

Frequently Asked Questions​
Generally, if you have one bathroom and great water pressure at your kitchen tap or outside tap, a combination boiler is normally the best choice for most people.
If you have got over one bathroom, then a conventional boiler (and even a system boiler) with a hot water tank could be the most effective choice for you.
No. For existing houses, if you have to change your gas boiler from 2035 onwards, you will not be able to put in another gas boiler. Going by current government plans, you would have to fit a Hydrogen boiler or a heat pump. Nevertheless, if your gas boiler is operating in 2035, you will not be required to do anything up until it needs to be changed, such as if it’s broken down & beyond repair.
It can differ widely depending on what you need.
But as a rough guide, to take your old boiler out & put a brand-new one in the exact same location varies from roughly ₤1800 to ₤3000.
And remove an old sort of boiler with a hot water tank {and} fit a combi boiler costs between roughly ₤3000 and ₤5000.

Why Should You Install A New A-Rated Boiler? Here Are 6 Reasons
1. Slash Your Heating 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. However you look at it, that’s a terrible waste.
If you replaced your boiler, controls – and maybe even your radiators – at least 92p of every £1 you spend will be put to good use. Only 8p or less would be wasted. That’s quite a saving – and when 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. Stop Paying For Boiler Breakdowns
3. Really powerful showers and fast filling baths
4. Stop running out of hot water
5. Create space
6. Don’t worry about turning the boiler on again.
