Recent Feedback
”George replaced our old heating system with a combi boiler. Excellent service throughout, very neat and tidy and we’re very happy with the result! Much quieter boiler and hot water pressure is way better! Would highly recommend and will definitely use again”
-Luke Stratford-Higton

Popular Boilers In Brockley, Lewisham

Vaillant Boilers
Vaillant are one of the best known boiler manufacturers in the UK. Vaillant are considered by heating engineers to be one of the best boiler brands around, winning Which? Best Buy awards on a regular basis.
Worcester Bosch Boilers
Worcester Bosch are probably the best known boiler brand in the country. If you want a high quality boiler, but still want to support British manufacturing, then Worcester Bosch is a great choice. Although they are among the most expensive boilers we install.


Viessmann Boilers
Viessmann is the greatest boiler manufacturer you’ve never heard of. We love Viessmann here at Thames Boilers because they’re as well built as (if not better) than Vaillant and Worcester Bosch, but their prices are a little lower. This makes Viessmann great value – and Which? agrees, giving Viessmann several ”Best Buy” awards in recent years.
Baxi Boilers
Baxi Boilers are another great British heating manufacturer, who can trace their roots back to Richard Baxendale, an iron founder, who began the Baxendale Company in 1866, based in Preston in Lancashire. Today, Baxi also makes boilers under the Main and Potterton brands. We recommend Baxi boilers as the least disruptive replacement for some conventional boilers – and their Main boiler brand for people who are on a budget.

Frequently Asked Questions
Generally, if you‘ve one bathroom as well as good water pressure at your kitchen tap or outside tap, a combination central heating boiler is typically the very best choice.
If you‘ve got more than one bathroom, then a conventional, also called a “heat only” central heating boiler (or perhaps a system central heating boiler) with a hot water cylinder could be the most effective choice.
No. For existing homes, if you have to replace your central heating boiler from 2035 onwards, you won’t be allowed to put in another gas central heating boiler. According to current government plans, you would have to get a Hydrogen boiler or a heat pump. Nevertheless, if your gas central heating boiler is operating in 2035, you won’t be required to do anything till it needs to be replaced, such as if it’s broken down & beyond repair.
It can differ extremely depending upon what you need.
Yet as a rough guide, to take your old central heating boiler out & put a new one in the exact same location varies from about ₤1800 to ₤3000.
And to remove an old kind of boiler with a hot water tank {and} install a combi central heating boiler costs between about ₤3000 to ₤5000.
If you need other jobs carried out at the same time, such as a power flush, a new gas pipe, or brand-new radiators, this will certainly add to the estimated price.
If you‘ve only got one bathroom as well as good water mains pressure, then yes.
If you‘ve got more than one bathroom or inadequate water mains pressure, then no{, you should look at a conventional boiler or a system boiler}.
Yes. There are a number of kinds of clever thermostats that can link to the net so you can regulate your central heating boiler from your phone. Some brand names customers go for are Nest, Honeywell, Tado, as well as Hive.

Time To Install A New Boiler? Here Are 6 Things You'll Love About It
1. Save Money On Your Heating Bills
If you’ve got a very old boiler with a pilot light, old radiators, timer and thermostat, 45p of every pound you spend on gas is wasted. Whichever way you look at it, that’s a terrible waste.
If you upgraded your boiler, controls – and maybe even your radiators – at least 92p in every £1 you spent will be put to good use. Only 8p or less would be wasted. That’s a big 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. More powerful showers and fast filling baths
4. Stop running out of hot water
5. Free up extra space in your home
6. Never worry about turning the boiler on again.
