If they are blue in white plugged they are 30/30 doors to the old standard and as long as there are intumescent strips in the door or frame and have the right ironmongery are effectively FD30 doors. If the installers back in the day just used a 25mm stop this invalidates the plug marking as it requires the intumescent for the performance to be acceptable. The 25mm stop dates back to before the existence of intumescent strips and if you have a door with the correct strips then the stop on a single door is immaterial. They would still be notional doors though and acceptable under the purpose built flat guide (which has been re-issued recently although a full revision is underway). Having said that I'd be more comfortable adding the intumescent strip that should always have been there and if doing that the additional cost of intumescent strips with cold smoke seals as oppose to just the strip is negligible enough such that you might as well go all the way and restore it to FD30S status. Your agent is covering themselves really - at least they aren't in the militant "rip out every door and door frame in the country and replace new" brigade that seem to be increasing in traction!

Yes to stop a fire in your flat preventing escape through the internal common stair and likewise making fire fighter access difficult. Flat front doors are primarily to protect others not the flat on fire. Whoever is the freeholder (or the TMC if all the flat owners share it) should have carried out a Fire Risk Assessment which, if suitable & sufficient, should have considered this, it's been a legal requirement for 15 years!

It could be of it forms an obstruction or narrows the path down the ramp to under 800mm.

If you own the land and there is no easement allowing others access for emergency or other purposes then they cannot legally do this - the fire regulations do not override property law in this instance. You could grant them a deed of easement to allow this for which you could charge a fee. I'd ask to see the risk assessment as well.

No it doesn't and leaseholders have overturned this at Tribunal in the past (especially where the doors were only visually inspected from one side and an arbitrary judgement made). Being 80's there is a fair chance these are already FD30S doors that might only need minor changes (e.g. if they use concealed chain closers they need changing to EN1154 overhead closers). The guidance they should be following is here: https://www.gov.uk/government/publications/fire-safety-in-purpose-built-blocks-of-flats

Any room can be locked when not in use unless it forms part of an escape route from an occupied area.

Ladders are not (normally) accepted as a means of escape and if the premises are compliant with the one stair and exit (which they probably will be) then that is the end of the landlord and agent's responsibility. There is nothing stopping you buying your own if you are really worried. https://www.safelincs.co.uk/fire-escape-ladders/

Only on some self testing fittings - which the majority aren't!

It isn't right. It's controlled waste under The Waste (England and Wales) Regulations 2011 so should have been removed and disposed of by a licensed contractor. More worrying is that cupboard is an extreme fire hazard with all that combustible stuff stored against the distribution board.

Sorry, my bad, meant leaseholder. They should think themselves lucky as usually they would have to install and maintain their own system (interfaced to the flats as required) at their own cost which is usually far more than a service charge contribution.

How does it open (other than manually) on power failure? This is the one stumbling block I've encountered with shutters where the motor is 240V or 415V. Otherwise the general principles seem sound in lieu of specific guidance.

Depends on where they are and why. If they are Georgian wired for impact protection then suitable toughened/laminated safety glass, if for fire then it needs to be 30 minute fire resisting glazing (which due to advances in technology over the last couple of decades can be clear without wires). Toughened/laminated safety glass is not fire resistant as a matter of course it needs to be specified as both. https://www.ifsecglobal.com/fire-protection/guide-to-fire-resistant-glass-and-glazing/

The white & green plug shows that door is a BWF certified Fire Check Door of 30 minutes stability & 20 minutes integrity that does not need separate intumescent strips as they are integral to the construction of the door located underneath the lipping. The white & blue plug shows that door is a BWF certified Fire Door of 30 minutes stability & integrity that does need separate intumescent strips in the doorframe. This system was used under fire doors under the old BS 476 Part 8 1972 standard where Integrity Failure is deemed to occur when cracks or other openings exist through which flames or hot gases can pass or when flaming occurs on the unexposed face & Stability Failure is deemed to occur when collapse of the specimen takes place. Current standard doors are measured by Integrity Only so the white/green doors would now be classed as FD20 doors for internal use in a flat and the white/blue door FD30 for the front door needing cold smoke seals as well as intumescent strips. Perko chains were accepted at the time but as they can't be adjusted they are unreliable and so usually should be replaced with proper closers. I very much doubt the fitters mentioned are competent if they are putting Perko chains in new doors! Other than some minor changes your doors seem fine and unless they are willing to pay to change them themselves may not be able to compel you to (especially as the door wasn't inspected) as some leaseholders found out when they took their freeholder to tribunal over fire door works and charges and won!

If the individual enclosures were to the latest standard of a non combustible housing and the area free from combustibles that would be a reasonable alternative - products to upgrade existing housings also exist:https://envirograf.com/product/electrical-consumer-unit-and-distribution-board-fire-protection-system/

Current benchmarks would require FD30S. The external door does not need to be a fire door unless an external escape route is nearby

If it's still under construction I suggest you contact your Local Authority Building Control department to have a look.

Depending on the country they may follow NFPA standards as oppose to BS - or nothing much at all!

As you should have gone through Building Control for this work they should have told you before signing it off. If you have been naughty and just gone ahead you need to get them in to regularise the work at which point they will tell you of any extra work needed. If you don't you don't only just risk prosecution you will find you have trouble when selling if the buyers surveyor & solicitor is in any way competent plus insurer's will love the get out of paying grounds too. I assume you haven't obtained planning permission as it's covered by permitted development - however too many people don't realise that whilst permitted development avoids the need to go through planning it absolutely does not avoid the need for Building Regulations approval. You are unlikely to have to change the rest of the house though, they will only look at the extension and where it joins the original house as the building work shouldn't change/affect the rest of the premises.

If the commercial unit does not have it's own self contained fire alarm system and is merely a zone off the common system then the freeholder has control over it - however the retail freeholder should have carried out an FRA and realised they need the call point and paid the freeholder to fit one. The freeholder will have put the detector in to protect the flats so could argue they have met their obligations whilst minimising false alarm risk - the retail unit may not, taken in isolation, be big enough to require a fire alarm system and the heat detector is only there to protect relevant persons in the rest of the building (flats above)

Unless it's specialised housing where the next level up is often required this would suffice as it's to the 1988 regulations.

Depends on what rights of access there are and if it falls under the Party Walls legislation. First port of call would be a property dispute solicitor and surveyor after checking for any access rights in leases, deeds, etc. Depending on the situation you may have legal remedy.

This is the guidance the pipeline has to comply with to be accepted in the stair: https://www.hse.gov.uk/pubns/priced/l82.pdf

It's a part 6 system that serves no purpose other to draw people into a smoke filled stair, usually these are either withdrawn or replaced with a compliant full evacuate system (i.e. sounders and detectors in flat lobbies) depending on the results of the FRA. You can't build a compliant Part 1 system using Grade D equipment so it can't be categorised as such.
