I've had a surveyor round my property tutting a lot at the fact a fire collar was not fit around an internal soil pipe that runs from the internal garage to the above floors. I understand his concerns in relation to fire passing through the gap surrounding the pipe.
My question being is: when was this regulation and if my property was built before the updated regulations do I have to fit this?
I've found this in regards to the collar but I'm struggling to understand a yes/no answer: https://www.gov.uk/government/publications/fire-safety-approved-document-b
