From my experience ( Oxfordshire ) what you have there is very unusual.
I would be against undertaking a repair that does not involve replacing the damaged area on a like for like replacement. Rats don’t just eat through pipe - there is something attracting them - light is the obvious cause. It may be that the original pipe was cracked - but if your photo is showing the full extent of the gnawed hole - that is a serious rat problem.
Fibreglass wont give you a light free repair, once rats sense light they will gnaw their way through it again - and you will be (possibly) be blamed!
Sorry, but I have been there on a “best endeavours” approach - then the customers insurance company attacked me. Not for the repair I undertook, but for the consequential damage that the “second invasion” of Mr and Mrs Ratty caused - eating the telephone cables!
I guess they were calling home!
