You need the manufacturers certification for the doors, this should have been included with the regulation 38 information and handed over with the building. However, given the age of the building, I would ask the builder to remediate under the warranty.

Mag locks are perfectly acceptable as long as the door cert allows them. Care must be taken when they are used on an escape route, they should fail safe in the unlocked position when the fire alarm is activated.

Basically, if the landlord lets the tenancy out to a group of individuals as a single entity then it is shared accommodation, if the landlord lets individual rooms out then it’s an HMO. But you need legal advice

1550mm divided by 5mm equalling 310 people

A proper fire risk assessment (which is a legal requirement) will tell you what you need to do

Yes, anyone can maintain the doors. Who are you going to get to sign them off? As I suspect that the firm you hired to inspect them wont. By the way, why did you go to a FIRAS Registered company to inspect the doors if Joe Blogs are going to maintain them

Its finding the right surveyor who is use to dealing with historical buildings. By taking a holistic approach to an overall fire risk assessment you can let somethings slide and beef others up, an example would be to put smoke heads either side of the door in lieu of closing the gaps. Of course this is all dependant of the risks and the purpose group of the property

Without looking at the building or some form of drawing I could not tell you, the listing part does not trump the RRO, the does however make it more difficult to comply

All depends on what they are made of and size and is there an alternate escape? You really need a fire risk assessment

Best way is to stop scrimping and install new door sets

As long as the frame meets the minimum requirements in the manufactures installation instructions then yes

A hotel comes under purpose group 2B, so no

The first question is what is wrong with the door? I am seeing far too many supposedly competent inspectors saying that because a door isn’t up to modern standards that they need to be replaced, they don’t, often some minor modifications can make them acceptable. As long as the installer is competent, they need not have 3rd party accreditation, but for doors you need someone like BM Trada or FIRAS if want a certified installation. As far as I know FENSA only deal with external doors and windows
