It's a brave person that tampers with an electrical fitting and changes it from it's OEM specification and certification. In theory you could try and justify this and have, for example, weekly testing instead of monthly, it's been successfully done for other fire related systems - but this was just altering the testing not the equipment.

Without carrying out the Fire Risk Assessment and thus being able to take all the risks, layout & other precautions into account it's impossible to say. My first concern would be if that is even a fire rated door in the first place - a closer and a sticker does not a fire door make....

Unfortunately a lot of people have jumped on the bandwagon and only done a short course, some of the 'accreditations' are awarded by the company providing the courses rather than a real qualification and you see lots of reports resulting in excessive work or incorrect assessment. There is nothing wrong with a certified door where the intumescent is concealed behind the lipping as long as it is in otherwise good order - the most upgrading it may need is a cold smoke seal depending on the location of the door and overall risk assessment for which surface mounted retrofit smoke seals (without intumescent) are available.

These internal closers are to the correct standard https://www.safelincs.co.uk/perko-powermatic-concealed-door-closer/?sku=SHR100SCP&fGB=true https://www.safelincs.co.uk/astra-3003-series-concealed-door-closers/?sku=FCAST3SS&fGB=true&gclid=Cj0KCQjwgYSTBhDKARIsAB8Kukv73fyww2nh1wBSzIbDlA0JZ27hi6wdRkl2SMkiKTX-nxSelizcjvIaAmpJEALw_wcB

Would someone have to pass the window to escape along the corridor, how wide is the corridor and is the bottom sill of the window under 1100mm from the ground? Is the corridor only open at the ends & enclosed along the length?

Building Regulations are not retrospective and the flat interior is not covered by the Fire Safety Order so you need not change anything. If you were completely remodelling the interior layout you might have an issue where extra measures may be required.

If you mean the LED that indicates there is a mains supply entering the fitting and the battery charger is active then it's not an individual part - you need a new fitting.

Depends on the location of the exit and any external escape routes passing it, but it's possible most of the time.

Is there an external stair adjacent? Is the walkway only allowing escape in one direction so you have to pass the door? Is the walkway narrow so you have to pass by the door or within a metre of it so there would be no avoiding any smoke/flame/heat? If the answer to any of these is yes then the external door should be a self closing fire door.

There's nothing to stop a fire exit route being used as a normal access route from a fire safety legislative point of view as long as it remains clear of obstruction, free from combustibles (usually if indoors), and readily available for use. It shouldn't be bolted if a dedicated fire route - I think the resident is using all this as an excuse to keep the area to themselves.

It doesn't sound healthy! I'd want that checked by an electrician.

Generally yes, but like with purpose built flats it depends on the size and layout - it's not an across the board approach and certain scenarios, even in purpose built, still require upgrade or replacement of doors.

It all depends on the size and layout of the block it's in - see here https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1020410/Fire_Safety_in_Purpose_Built_Blocks_of_Flats_Guide.pdf

That's a drop over 300mm so the creation of the drop doesn't comply with Building Regulations, would breach the Workplace (Health Safety & Welfare) Regulations and will get the no win no fee compensation lawyers lining up to take the case when someone falls off it! Hardly a safe means of escape either.

You are using the incorrect guidance - BS9999 is not for flats and is for designing new non domestic buildings. Blocks of flats have far more onerous smoke control requirements due to their fire strategy being of stay put. Existing flats should be assessed to this guide (& then it's impending replacement) https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1020410/Fire_Safety_in_Purpose_Built_Blocks_of_Flats_Guide.pdf

HI, You have asked this on FireNet so I'm not going to duplicate on here, I've asked some further questions to clarify matters and have a full answer ready once these are replied to

There is nothing stopping you locking this door, although it would be advisable to have a lock that can be opened from the inside without a key to allow emergency escape. The fitting of the lock should not compromise the integrity of the fire door so should follow the door manufacturers instructions.

Single 12.5mm plasterboard with a plaster skim used to be the standard for 30 minutes fire resistance a long time ago but the current manufacturers guidance based on testing is that you now need to use 2 x 12.5mm. However there are different material combinations for different situations, the British Gypsum White Book (https://www.british-gypsum.com/specification/white-book-specification-selector/white-book-overview) is a useful reference. You should contact your Building Control department as they will have a minimum spec they will accept.

Commercial use is different to domestic - guidance is here https://www.fira.co.uk/technical-information/flammability/fire-safety-of-furniture-and-furnishings-in-the-contract-and-non-domestic-sectors

The requirement for internal fire doors to self close in dwellings was removed a long time ago so the previous occupier will have legitimately removed them. You should of course try and keep the doors closed where possible, especially at night.

If they are on an internal door you can cut the chains - it used to be a requirement to fit these a long time ago, but this was dropped some years ago.

Grade F systems only have a single power supply and are more prone to removal and failure. The robust nature of a Grade D system is why it is now the norm and the use of Grade F equipment is being phased out slowly as legislation requires more and more places to have Grade D (or higher) when built, rewired or altered. Wireless linked systems are the norm and the old need for linking physically with bell cable is long gone

HI, For full detail you would need to appoint someone to prepare such a specification but to avoid you ending up with over provision: - Your description suggests the conversion will comply with the current edition of Approved Document B or BS9991 with the requisite fire compartmentation - This in turn suggests a stay put approach - Flats would have their own separate & self contained smoke/heat alarms to BS5839-6 - You do not need any form of common fire alarm system - You only require smoke detectors to open the smoke vent, no sounders, no call points - Despite it being common (& lucrative) practice there is no need to provide a separate fire detection system to activate the vent - there are several manufacturers of smoke vent equipment where all the required detectors, manual controls, etc can be directly connected the the vent controls with out the need for a fire alarm control panel etc - One example: https://aov-direct.co.uk/product/ventec-ostro-1m2-gfa-stairwell-aov-kit/ - This way you won't have to pay for installation of and pay for ongoing testing of equipment you don't need, just the smoke control system and no unnecessary components that aren't correct for stay put.

30 minutes protection would usually be accepted and you could potentially uprate the existing cupboard using intumescent card, paper or paints
