Hi,

I am considering offering a door trimming service for newly installed carpets/flooring where fire doors are already present.

What would be advisable in terms of training to undertake this service?

Thanks   

You need to fully understand about fire doors and one answer is to follow Neils advice at https://www.safelincs-forum.co.uk/topic/4122-what-certification-is-needed-to-be-allowed-to-install-fire-doors/?do=findComment&comment=13249 or consider self study using Best Practice Guide to Timber Fire Doors with all the additional guidance literture at https://www.asdma.com/knowledge-centre/.
