Absolutely unreasonable and not anywhere in guidance - if this were true every terrace of houses in the country would have to have a fire door as it's front door

For fire safety they are only required where doors on escape routes sub-divide corridors, or where any doors are hung to swing both ways, others will have been likely fitted under Approved Document M for general accessibility.

If it's a stay put block it wouldn't have the communal call points and smoke alarms (in fact Building Regs & Fire Safety guidance says it absolutely should not) and would have smoke control (or at least openable windows to the stairs). Where is it? If it is in Wales the sprinklers are mandatory regardless of the evac strategy, if England they could be compensation for a departure from the normal guidance which may be pertinent to your problem. I can see how the assessor got mixed up - your current set up, using standard benchmarks, is incorrect for both stay put & full evacuate. The build is modern enough for it to be a legal requirement for the fire strategy & fire safety information relating to the design to be handed over on completion to the freeholder/owner/RMC who has a legal duty to maintain that information and pass it over if they sell the premises - this would answer the questions about the design. If the flat detection is linked to the common detection then you are set up correctly for an evac policy as it is with no changes. Fire doors do not need closers other than to the flat entrance doors where no relaxation exists in any build guidance. If the electrical board is made with a non combustible housing (metal) then it can be argued no further enclosure is necessary (opinion is sometimes divided on this). The Emergency Lighting has to be tested and the test switches make this easier - it's a sign of a poor build that they are not there as they are pretty standard and should have been there from new! Building Regs sign off is no guarantee of full compliance with the Regulations, nor of the fire safety legislation that takes force on completion - plenty of modern builds have been found to be defective despite this, sometimes with total loss fires or fatalities as a result. Building Control have no liability and it rests instead with the developer. If your FRA did not attempt to access at least a proportion of flats to examine the front door fully (both sides, top & closing) and see if the common alarm extends inside it is not compliant with current Government guidance for a suitable & sufficient FRA (as part of this, if readily accessible the roof void should also have been accessed) so you haven't had what you paid for. Housing is far more specialist than many assessors assume and this is an example of a site where a careful eye is needed! I can't give you a more definitive answer without seeing the site, remote advice can only go so far!

I suggest you take the Government Guidance as evidence and take the matter to a First Tier Tribunal for review as an excessive and unjustifiable requirement, also you need to get a copy of the block Fire Risk Assessment which, if competent, should detail the grade of fire doors required and if notional doors (those to the standard at the time of installation) are acceptable, which unless there is something really left field with your block it should. Too many 'zero to hero' poorly trained door assessors are out there chasing volume inspection work or remedial/replacement work with minimal knowledge and can't handle anything more complex than a brand new door to brand new standards. I've advised countless leaseholders on this and given evidence for FTT's as this is not an isolated issue!

If your premises is 'Stay Put' it should not be a critical defect, although one that should still be promptly resolved. If it had been a High Rise Residential Building in England over 18m/7 stories then, as a fault lasting over 24 hours, there would be a legal requirement to report this to the Fire Service, however no such duty exists for your size of block, but if you are concerned you can still consult the Business Fire Safety department of your Fire Service (where enforcement officers are based including those covering flats) or for general home fire safety guidance the Community Fire Safety department

As stated a swing free closer is the best solution. Whilst bathrooms are traditionally low risk from a fire door and detection point of view (unless containing unusual risk not itself enclosed like a boiler) there is precedent in England & Wales for some care premises bathrooms to be considered higher risk when electrical mobility equipment is present (particularly if with back up batteries on trickle charge which with modern equipment could be lithium ion batteries) and I have seen enforcement action down here requiring detection & self closing fire doors so it's not unprecedented.

The sockets themselves contain all required safety mechanisms - https://www.fatallyflawed.org.uk/

How easy would you be able to walk into another job? If it's a bad as it sounds & they don't seem to care then it's time to consider 'dropping a dime' to the HSE (as we have process fire risk and H&S issues so sits more in their camp than the fire service) but even with whistle-blower protection if they think it was you then things may get awkward. Is the mixer and it's compressor ATEX as well?

If you are going to add an extra detector, then to be of any use it should be part of the main system, not self contained. If it's a licensed HMO it's worth checking with the Local Authority that they accept an upgraded door in their fitness standards- traditionally upgrading with board as you suggest was an official method in many LA's local guides for many years but times change and it's worth double checking as standards do vary between LAs

Could you please post a picture of the closer?

Ah - Wales! Very different then!

1 - A stair landing with no rooms on/off it does not need a detector to meet The Smoke and Carbon Monoxide Alarm (England) Regulations 2015 (as amended) 2 - You can't usually link Grade D (mains) & Grade F (battery) alarms. However it sounds like the flat already has the legally required detection & under answer 1 does not need the additional one.

An inward opening door cannot, by it's very nature, have a push bar or push pad type fastening (pushing & pulling at the same time is asking for disaster)- but if used by less than 60 persons it need not and a BS EN 179 type A (lever handle operated emergency device) fastening would be appropriate. If you need panic proof escape then the door would need to be rehung. If it opens directly onto the escape stair then unless it is the top floor of the escape it needs to be a fire door (of which metal ones are available)

Firstly you need (it's a legal requirement) a Fire Risk Assessment by a competent specialist who will address this and any other issues. Stairs are, by their very nature, open shafts, but this is not an issue is the stair is a protected route with 30 minute fire resisting construction and 30 minute self closing fire doors with intumescent strips (or depending on a variety of factors possibly even original fire doors with a 25mm rebate). If the offices were fully legally compliant the stairway should already have this protection as well as a suitable fire detection & warning system and emergency lighting.
