Difficult to comment without seeing the detail but I have seen a lot of FRA’s which treat Listed Buildings the same as new builds – they are often not particularly Fire Risk Assessments but audits of everything which doesn’t comply with the current regs (which is usually mostly everything). Internals of individual flats ARE NOT covered by the requirements of the Fire Safety Order so I am puzzled as to why these have been included, they should be assessed under the Housing Act and the Housing Health and Safety Rating System HHSRS but some Fire Risk Assessors don’t seem to appreciate this. So the concept of an individual dwelling “failing” the FRA does seem to be a bit odd.
Conversely front doors of individual flats are covered as are all common areas and externals and if there were compartmentation issues then that would be relevant although most FRA’s seem to omit any reference to compartmentation.
I am a Chartered Building Surveyor, Registered Fire Risk Assessor for Heritage Buildings and CIAT-Conservation Accredited so do know a bit about this subject. Feel free to drop me an email if you want any further advice. tim@timothyrichardson.co.uk
