Do I need building regulations for a glass roof?
Usually exempt when like for like. Replacing one translucent roof with another usually keeps the conservatory within the exemption, provided it stays separated from the house by external quality doors and has no extension of the main heating. Building regulations guide.

Expect 25 years plus, depending on the system, the installer and the maintenance. Check the length and type of guarantee on each quote, and whether it is insurance backed.
