Customers In Hadleigh Like These Boilers

Vaillant Boilers
Vaillant are one of the most popular boiler brands in the UK. Vaillant were apparently the first company to make a “combi” boiler back in the early 60’s. So they’re very well established.
Worcester Bosch Boilers
Worcester Bosch are one of the best known boiler manufacturers in the country. If you want a high quality boiler, but still want to “buy British”, then Worcester Bosch is an excellent choice. Although they are some of the most expensive boilers we install.


Viessmann Boilers
Viessmann is the best boiler make you’ve never heard of. We’re big fans of Viessmann here at Thames Boilers because their build quality is as good as (if not better) than Vaillant or Worcester Bosch, however their prices are a little lower. This makes them great value – and Which? magazine agrees, giving Viessmann boilers several Best Buy awards in recent years.
Baxi Boilers
Baxi Boilers are another great British heating make, founded in the industrial revolution by Richard Baxendale, an iron founder, who started the Baxendale Company (now Baxi) in 1866, based in Preston in Lancashire. Today, Baxi also makes boilers under the Main and Potterton brands. We usually 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.

Frequently Asked Questions
As a rule, if you have one bathroom as well as good water pressure at your kitchen tap or outdoors tap, a combination boiler is generally the best option for most people.

It can vary extremely depending upon what you require.
Yet as a rough guide, to take your old boiler out and put a new one in the same location ranges from about ₤1800 to ₤3000.
