I have a Viessman boiler that was installed around a year and a half ago and is now overdue the service.
I called the installer who advised a price of £78.
I am also getting a new bathroom in just now and the plumber said he would do it for £35 and is Gas Safe registered.
Do I have to get a Viessman approved person to carry out service to keep the 5 year warranty valid?
Thanks in advance.
