To make sure your new Vaillant ecoTEC boiler meets your individual needs, we recommend that you obtain a quotation from three central heating installers before appointing one to do work on your behalf. All domestic boiler installers in the UK must be registered with a competent person's scheme such as Gas Safe; this way you know that your boiler will be installed correctly. All central heating installers on our site have been trained by Vaillant in our Centres of Excellence and are part of the Vaillant Advance loyalty scheme to ensure that only the best tradesmen are installing our products.

As the heating installers listed on this website are not employed or approved by us, Vaillant cannot accept any responsibility for their workmanship. The terms of the Vaillant Group guarantee on the quality of manufacture of the product remains unaffected.
