You wouldn't want to use a roof as an exit as you would then be trapped with fire & smoke of course liking to rise (look at the Joelma Building Fire) A single protected stair is an acceptable escape route in many situations

It's unlikely to significantly enhance the fire resistance as it's not thick enough or anywhere near the tested specification (https://files.mutualcdn.com/medite-smartply/files/TEUSG0429-Rev01-Medite-Prem-FR-Euroclass-C-30-minute-FR-Partition-Wall.pdf) Euroclass ratings are for a wall or ceiling linings reaction to fire not their ability to hold back fire. Plasterboard or Gypsum board is more common for use to increase fire resistance of walls & doors https://files.mutualcdn.com/medite-smartply/files/Specification-Guide-to-Flame-Retardant-Wood-Panels-Part-1-REV0.pdf https://files.mutualcdn.com/medite-smartply/files/Specification-Guide-to-Flame-Retardant-Wood-Panels-Part-2-REV0.pdf https://files.mutualcdn.com/medite-smartply/files/Specification-Guide-to-Flame-Retardant-Wood-Panels-Part-3-REV0.pdf

That may well be a potentially suitable upgrade - some premises go down an alternative route, especially where there isn't much room for a bulky cupboard: https://envirograf.com/product/ecu-fire-protection-system/

When were they built - Building Regulations are not retrospective, but fire safety regulations allow for technical progress in assessing risk meaning in some situations corrective work is required. Government fire risk assessment guidance expects an existing block of flats to have a divided roof space if retaining a stay put policy, but on the other hand doesn't require new flat front doors if the original flat doors are fire doors to the standard of the time of build and are still in good condition. It's risk assessment driven - ask for the Fire Risk Assessment carried out for the block as the management company is now legally obliged to provide you with details of the risks and protective measures in the building as well as the identity of the fire risk assessor.

British Standards and the like are not retrospective by themselves. The Fire Risk Assessment, which has to account for technical progress, has to determine if the existing precautions remain tolerable without modernisation - in many cases they are still suitable (especially if other aspects have been modernised. Example - a hotel in the 1970's could comply with fire safety legislation with either no smoke detection or provision just to the stairs and corridors - this would no longer be tolerable as lack of any, or just limited, detection in any sleeping accommodation has been proven to be an unacceptable risk to life so the current standard requires detection throughout most areas of the hotel including bedrooms and it would be expected this is retrospectively applied & legally enforceable. On the other hand the same hotel would have original fire doors with a wooden stop on the frame instead of the current standard of intumescent strips and smoke brushes but could (& have in legal cases) justify not replacing them where they were in good working condition & the premises had more detection than when first approved. They only need to work to the 2025 standard for service intervals and actions and for major additions/new systems - the system itself does not need to be current as long as it still performs adequately and the FRA says such.

https://www.gov.uk/government/publications/fire-safety-in-purpose-built-blocks-of-flats Usually you need your own expert report - clients going to First Tier Tribunals often use these - unless you can convince them with this guide that does not require external doors to be fire doors except in limited circumstances (not yours)

If that is a final exit to the outside then there is every likelihood it doesn't need to be a fire resisting door so you can simply fill the holes with whatever you want to prevent draughts.

No it isn't - an external entrance door does not need to be a fire door unless onto an external escape stair or a balcony with escape in only one direction.

All I can find free are: https://assets.publishing.service.gov.uk/media/6243119ce90e075f1088f5c1/ps-11-fire-safety-march-2022.pdf https://www.legislation.gov.uk/ukdsi/2018/9780111164631/pdfs/ukdsi_9780111164631_en.pdf So it looks like having to pay for it - if it's like the other ones for special sectors like BB100 for fire safety design in schools in it's depth and specific content it should be worth it if doing prisons work (have you tried asking the establishment you are working at for a copy?)

First Tier Tribunal - challenge the necessity for the door being changed - most flat fire door replacements are not required to meet the functional requirements of the law and the guidance (which has special status such that if you follow it you tend to be deemed compliant if someone alleges there is an issue) However you need to establish that the current doorset meets the requirements applicable to the block - the minimum standard being based on age, layout & height of the block. This note reinforces that wholesale replacement is often not required - https://www.gov.uk/government/publications/fire-safety-england-regulations-2022-fire-door-guidance/fire-safety-england-regulations-2022-fire-door-guidance

It's not quite a BS7273-4 device, but it's probably the nearest guidance - this would equate to weekly rotational testing, servicing in accordance with manufacturers instructions = basically it's risk assessment based

Yes, for the external walls and due to the hallway. Not many requirements would be expected to come off the back of it though.

It may be at a lower than usual height for wheelchair users (even though I'm guessing there aren't any!) Their safeguarding & fire risk assessments need to match up to provide a suitable balance between placement for escape and placement to avoid children escaping.
