”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”

”George was punctual and very reliable. He always turned up at the day and time agreed. Genuine, professional and friendly he carried out the work within the given time. He was good at communicating progress throughout the day and I appreciated him minimising noise during my daughters nap time! I would recommend George for any of your boiler needs.”

People In Upper Norwood Choose These Boiler Brands

Vaillant Boilers
Vaillant are one of the most popular boiler manufacturers in the UK. They were apparently the first company to make a “combi” boiler back in the early 1960’s. So they’re a well established company.
Worcester Bosch Boilers
Worcester Bosch are one of the best known boiler brands in the UK. If you want a top of the range boiler, but still want to support British manufacturing, then Worcester Bosch is a great choice. Although they are some of the most expensive boilers we install.


Viessmann Boilers
Viessmann are the greatest boiler manufacturer you’ve never heard of. However, don’t let that put you off. They’re a huge brand in Europe and, like Vaillant, they’re German and have been around for over 100 years.
Baxi Boilers
Baxi is another great British heating manufacturer, whose roots go back to Richard Baxendale, an iron founder, who started the Baxendale Company (now Baxi) in 1866, based in Preston in Lancashire. Today, Baxi also make boilers under the Main and Potterton brands. We recommend Baxi boilers as the least disruptive replacement to some heat-only boilers – and their Main boiler brand for people who want to keep costs down.

Common Questions From Our Upper Norwood Customers​
As a rule, if you have got one bathroom and good water pressure at your kitchen tap or outdoors tap, a combination boiler is usually the best option for most people.
If you have got more than one bathroom in your home, then a conventional, also called a “heat only” boiler (or even a system boiler) with a hot water cylinder could be the most effective option.
No. For existing houses, if you have to change your central heating boiler from 2035 onwards, you will not be able to put in another gas boiler. According to 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 till it needs to be changed, such as if it’s broken down and beyond repair.
It can vary extremely depending on 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 about ₤1800 to ₤3000.
And to remove an old type of system with a hot water storage tank {and} put in a combi boiler costs between about ₤3000 to ₤5000.
If you need various other jobs carried out at the same time, such as a power flush, a new gas pipeline, or brand-new radiators, this will add to the estimated costs.
If you have got 1 bathroom and good water mains pressure, then yes.
If you have got more than 1 bathroom or poor water mains pressure, then no{, you should look at a conventional boiler or a system boiler}.

6 Benefits You Get With A New High Efficiency Boiler
1. Slash Your Heating Bill
If you’ve got an old boiler with a pilot light, old radiators, timer and thermostat, 45p of every pound you spend on gas is wasted. However you look at it, that’s an awful 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 quite a 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. Stop running out of hot water
5. Create extra space at home
6. Never worry about turning the heating on or off again.
