Customer Comments
”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 replaced our boiler recently. He was really friendly, reliable and fair with pricing. Would definitely recommend and will be booking in for annual boiler services without a doubt.”
-Emma T
“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
Rayleigh's Most Popular Boilers

Vaillant
Vaillant are one of the best known boiler manufacturers in the UK. Vaillant are thought to be one of the best boiler makes on the market, winning Which? Best Buy awards on a regular basis.
Worcester Bosch
Worcester Bosch are probably the best known boiler brand in the country. Like Vaillant and Viessmann boilers, Worcester boilers have won several Which? Best Buy awards.


Viessmann
Viessmann are the best boiler manufacturer you’ve never heard of. We love Viessmann at Thames Boilers because their build quality is as good as (if not better) than Vaillant and Worcester Bosch, but their prices are a little lower. This makes Viessmann fantastic value – and Which? magazine agrees, giving Viessmann boilers several Best Buy awards in recent years.
Baxi
Baxi is another great British heating manufacturer, founded in the industrial revolution by 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 heat-only boilers – and their Main boiler brand for people who are on a budget.

FAQ​
Generally, if you‘ve one bathroom and also excellent water pressure at your kitchen tap or outside tap, a combination boiler is normally the very best choice.
If you‘ve got more than one bathroom, then a conventional, also called a “heat only” boiler (and even a system boiler) with a hot water cylinder could be the most effective choice.
No. For existing houses, if you have to change your gas boiler from 2035 onwards, you will not be able to replace it with another gas boiler. Going by current government plans, you would have to install a Hydrogen boiler or a heat pump. However, if your gas boiler is working in 2035, you will not be required to do anything up until it needs to be replaced, such as if it’s broken down and irreparable.
It can vary hugely depending upon what you require.
However as a rough estimate, to take your old boiler out and put a new one in the same place ranges from about ₤1800 to ₤3000.
And strip out an old kind of heating system with a hot water storage tank {and} install a combi boiler costs between about ₤3000 and ₤5000.
If you require other jobs carried out at the same time, such as a power flush, a new gas pipe, or new radiators, this will certainly add to the estimated costs.

Time To Install A New Boiler? Here Are 6 Things You'll Love About Them
1. Save Money On Your Heating Bills
If you’ve got an old boiler with a pilot light, old radiators, timer and thermostat, 45pence of every pound you spend on gas is completely wasted. Whichever way you look at it, that’s a terrible waste.
If you replaced your boiler, controls – and maybe even your radiators – at least 92pence of every £1 you spend will be put to good use. Only 8pence 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. Really powerful showers and faster filling baths
4. Stop running out of hot water
5. Free up extra space in your home
6. Don’t worry about turning the heating on or off again.
