Hadleigh's Favourite Boilers

Vaillant Boilers
Vaillant are one of the best known boiler makes in the UK. Vaillant were apparently the first company to make a “combi”also known as a “combination” boiler back in the early 60’s. So they’re a well established company.
Worcester Bosch Boilers
Worcester Bosch are probably the best known boiler brand in the UK. Although now owned by the massive European brand, Bosch, Worcester boilers are still very much a British company. Its boilers are still made in Warndon in Worcester.


Viessmann Boilers
Viessmann is the best boiler manufacturer you’ve never heard of. We love Viessmann at Thames Boilers because they’re as well built as (if not better) than Vaillant and Worcester Bosch, however their prices are a little lower. This makes them great value – and Which? agree, giving Viessmann boilers several ”Best Buy” awards in recent years.
Baxi Boilers
Baxi is another well established British boiler manufacturer, started in the industrial revolution by Richard Baxendale, an iron founder, who started the Baxendale Company in 1866, based in Preston in Lancashire. These days, Baxi also make boilers under the Main and Potterton brands. We usually recommend Baxi boilers as the least disruptive replacement to some heat-only boilers – and their Main boiler brand for people who are on a budget.

FAQ​
As a rule, if you‘ve got one bathroom and also excellent water pressure at your kitchen tap or outdoors tap, a combi central heating boiler is typically the very best option for most people.

It can vary extremely depending upon what you require.
But as a rough guide, to take your old central heating boiler out and put a brand-new one in the exact same place varies from roughly ₤1800 to ₤3000.
