Who is responsible for the installation is a legal question.

Correct use of fire foam
Personally I hate this stuff, it is very rarely used correctly. The rule of thumb is that when installed the depth should be at least 10 times the width, basically narrow linear gaps. If you do use it then you must get the certfire certificate for the product to see how it should be installed and the gaps that it can seal.

Fire door regs for 3-storey flat blocks under 11 metres
1. The sealing of electrical cables, where the cable enters or exits the riser should be stopped. 2. If they are serviceable and are manufactured from solid metal with a melting point of at least 900C, then no 3. I agree with the inspector, you should put in program to bring the doors up to nominal standard, prioritising smoke (look at batwing or combined seals) and gaps. Fire doors should have 3 hinges, however if the door is small an exception can be made. Can you ignore it, yes, however, you should come up with a written answer to all the defects and how you propose to rectify or compensate for each. Should anything happen, the first port of call will be the FRA, the next will be a man with a curly wig asking you why you ignored the FRA. For fire door inspections If a flat owner or resident refuses to allow a fire door inspection, they are potentially hindering a legal safety requirement under the Regulatory Reform (Fire Safety) Order 2005.

Fire doors in a domestic 3 storey house
A self-closer is no longer required, however care should be taken when filling the holes as the door should be still a FD20 if it is on a protected route

Riser cupboards and communal doors in a 2 storey residential block built in 2005
Yes ADB only applies to new builds and material alterations, however the RRO and following a small fire in London, the Fire Safety Act 2021 enforce general fire safety of existing buildings. The regulations have not distally changed with respect to smoke control for communal doors or riser doors, in the past 25 years. Given the age of the building, I would have thought that a gap of 6-8mm the doors were never to standard.

NFR Rated Door - Remedial Works
Check the original as built fire strategy as office doors do not usually need to be fire rated (except dead ends, high risk areas etc). It may be that at some point in time someone has put fire signage on the doors Protected corridors 2.24 A corridor serving as part of the means of escape in any of the following circumstances should be a protected corridor. a. Every corridor that serves bedrooms b. Every dead-end corridor (excluding recesses and extensions a maximum of 2m deep, as shown in Diagrams 2.7 and 2.8). c. Any corridor shared by two or more occupancies (paragraph 2.17). Enclosure of corridors that are not protected corridors 2.25 If a corridor is used for a means of escape but is not a protected corridor, even though the enclosing partitions may have no fire resistance, both of the following should be met to inhibit the spread of smoke. a. Partitions should continue to the soffit of the structural floor above, or to a suspended ceiling. b. Openings into rooms from the corridor should be fitted with doors, which do not need to be fire doorsets. Open planning will not inhibit the spread of smoke, but occupants can become aware of a fire quickly.

PAUL ROGERS
Without knowing the building it’s impossible to answer, but as a rule of thumb, if it is possible for smoke to affect the escape route then there should be smoke seals. The cost difference between smoke and not smoke is negligible. The who is responsible for the cost is a matter for the tenancy agreement and is not a fire safety issue, but ultimately, I suspect that it will fall on the leaseholder

What gap under fire door
The maximum gap for a smoke door is 3mm. It may be possible to fit a threshold seal, but I have never come across one that would bridge that gap It may also be possible to lip the door, but again I have never come across one that would bridge that gap You could put a 17mm hardwood threshold detail under the door fixed to the floor, but that may cause a trip hazard

Management co demanding new flat doors
A 15-year-old door would be as compliant with the latest regulations as when it was installed, the regulations for fire doors have not changed, however, there is no guarantee that the doors were compliant then installed or that the doors have not been altered that would make them uncompliant. You should ask the agent why they are not compliant, it may be a latent defect which may be there responsibility

FD30 vs FD30S for Block of Residential Flat built in 2017-2020
Correct, flat doors should be FD30S, this has been the case since at least December 2018. To comply, the head and side gaps should be 3mm ±1mm (irrespective of smoke). The threshold on a smoke door should be a maximum of 3mm. I suspect that the door was never compliant in the first place.

Replacing fire rated glass
Legally, as long as they are competent, anyone can do it, but it must be correctly installed (the inspector will fail it again if not)
-
Intumescent strips
The door should be routered to accept the intumescent strips, they should not alter the door gap. The smoke fins can sometimes bind, some Vaseline can be applied to soften the blade
-
Final exits in enclosed areas
It all depends on the size of the enclosed area and the risk. If the area is big enough you can call it a place of ultimate safety, but technically it should allow for the restricted dispersal of people

Hotel Fire Safety Barred Windows?
For anything above the second floor, you are more at risk of serious injury or death from jumping out of the window than the fire itself. A decent alarm system should notify you long before the escape route becomes untenable, if the fire is on the other side if the door, you will have a minimum of 30 minutes for the fire brigade to rescue you

Inward Firedoors and Fire Routes
The use of magnetic hold open devices kind of defeats what the regulations are trying to do here. Without seeing the doors, I suspect you have 2 options; 1. Change the swing of the doors 2. Limit the occupancy of the room

Cross corridor doors
You may get certification to say that the building was built to building regulations, however a building that was built in the 1980s it does not mean it comply with the current building regulations. Any alterations or maintenance to building would make the original certification null and void as what was signed off is not what was is there now. You need to look at the regulation 38 information, which should be an up-to-date record of all the fire safety information for the building Including fire doors along with the latest FRA and any recent fire surveys to get an holistic view.
