Why and how does Worcester, Bosch Group offer accreditation to some installers?

Worcester want to provide homeowners with peace of mind when they are upgrading their home heating system and only invite heating engineers who are deemed as reputable, quality conscious and representing value for money. Worcester Accredited Installers must have relevant Gas and oil Safe, OFTEC and/or MCS approval. WAI's must also have attended Logic certified training courses on boilers, solar thermal systems, heat pumps and/or underfloor heating.

Worcester check the installers' Gas and oil Safe, OFTEC and/or MCS accreditation on a regular basis. However we always recommend to homeowners that they verify a heating companies membership status with the awarding bodies directly via their governing bodies.

Why do I need a Heating & Hot Water Installer?

Due to the complexity of modern heating systems, installation, service or repair work should only be undertaken by a qualified heating engineer.

This is why most manufacturers of heating and hot water appliances such as boilers, solar thermal and heat pumps only suppy through trade merchants, rather than directly to end users.
