Replacing fire rated glass

[Guest Danny]

Can a Third party accredited door installer replace glazing on a fire door or does it have to be a certified glazing company? There is a fire door with no information and we have been told glass may not be fire rated and  have been advised by a door inspector to replace glazing.

Legally, as long as they are competent, anyone can do it, but it must be correctly installed (the inspector will fail it again if not)
