New Cross's Most Popular Boilers

Vaillant
Vaillant are one of the best known boiler manufacturers in the UK. They’re a German firm, with their headquarters in Remscheid since 1874.
Worcester Bosch
Worcester Bosch are probably the best known boiler brand in the country. 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
Viessmann are the greatest 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 Viessmann fantastic value – and Which? agrees, giving Viessmann several Best Buy awards in recent years.
Baxi
Baxi Boilers are another great British heating make, founded in the industrial revolution by Richard Baxendale, an iron founder, who began the Baxendale Company (now Baxi) 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 brand for people who want to keep costs down.

Most Asked Questions From Our New Cross Customers​
Generally, if you have one bathroom as well as good pressure at your kitchen tap or outside tap, a combi boiler is generally the best option.
If you have got over one bathroom, a conventional boiler (or even a system boiler) with a hot water tank would be the best option.
No. For existing houses, if you have to replace your central heating boiler from 2035 onwards, you will not be allowed to replace it with another gas boiler. According to current government plans, you would have to get a Hydrogen boiler or a heat pump. However, if your gas boiler is working in 2035, you will not be required to do anything till it needs to be replaced, such as if it’s broken down and beyond repair.
It can differ hugely depending on what you need.
But 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.
And to strip out an old sort of boiler with a hot water 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 new radiators, this will certainly contribute to the estimated price.
