The fire alarm in the flat should be a domestic fire alarm BS 5839 part 8 confined to the flat the only, person that will be disturbed will be the flat owner. The rest of the premises would have a BS 5839 part 1 which may have a heat detector in the flat to warn the building that there is a fire in the flat especially when the flat is empty. Without a survey I cannot give you the full details and I do not do surveys.

When you purchased the fire door blank you should a got a global assessment that gives all the information to construct a fire door set. Check out this global assessment for the indicated fire door blank. https://www.falconpp.co.uk/media/1640/flamebreakfd30revm.pdf

You should replacing the doors with fire door sets which are the fire door and frame which has been manufactured according to the specifications of the ones that have been tested. Check out what is meant by fire door sets https://www.safelincs.co.uk/fd30-single-fire-door-sets/.

I think this is aimed at Health and Safety not fire safety I would only use the principals and devise my own system.

Wallcoverings which conform to BS EN 15102, achieving at least class C-s3, d2 and bonded to a class A2-s3, d2 substrate, will also be acceptable. I know this dosent help much, as finding a manufacturer who has tested his wallpaper, would be a rare as hens teeth and other than flock wallpaper which is a no no I would consider most thin wallpapers would be satisfactory I think all you can do is rely on is your own experience.

It depends on the size and layout what fire alarm you require and the details you have given is not sufficient.

It all depends on the layout if you could get a 30 minute fire resistant separation between the route into the yard and out of the yard it could be acceptable otherwise you would need a separate way out the yard.

The only thing you could do is to employ a metal fire escape inspector/surveyor and get a report. How you would share the costs would be a problem and as these surveyors are usually attached to fabricators getting a truly independent survey would be problematic.

As it is a commercial premises it is subject to the RRFSO and the enforcing authority is the local fire service so you should contact them. Check out https://www.firesafe.org.uk/uk-fire-rescue-services-details/

Most of your questions are answered on page 19 of Fire safety of furniture and furnishings in the home A Guide to the UK Regulations and anything supplied by you needs to meet the regulations, anything supplied by the client is not subject to the regulations. If it does not fully meet the regulations you cannot fix labels but you should advise the client in writing of the full details. Any fire retardant spray or liquid should be certificated in writing and any queries you have, is better answer by them. Any items manufactured after 1950 then refurbished and sold by you should fully meet the regulations.

If you can prove that the level of borrowed light will provide the necessary level and availability during all relevant times, then emergency lighting should not be required.

A full height riser needs needs a minimum full half hour standard separation internal and external so I think you are correct.

If the finish construction meets an half hour standard closing the meter/ancillaries and satisfiers' building control it should be satisfactory.

I have more faith in the general public than you, if the signs are fixed as AB has indicated they would find there way out quite easily.

Does the fire door require to be able to control cold smoke because if it is a fd30 fire door the maximum 4mm gaps only apply to the sides and the top, if it is a FD30s it would also include the threshold gap or fit cold smoke brushes and you would need controlled ventilation panels. You never said what type of premises it is, domestic or commercial.

Yes 2mm to 4mm check out BS 8214: 2016 https://shop.bsigroup.com/ProductDetail/?pid=000000000030332501 IFSA https://www.ifsa.org.uk/documents.

Ian are you answering a question if so what is the question or making a rhetorical statement that most retail emergency lighting sources are not actually 3rd party approved.

All final escape doors should be openable from the inside, without a key, when the premise is occupied, access from the outside is immaterial.

There are a number of methods used, you have mentions two. The head of each department or floor should know who is present and ensure that those under his control, properly evacuates, then reports it to the person who will be talking to the fire service. It is important to know who is in the building and then ensure they are all present at the roll call.

Check out Building Regulations. Meaning of material alteration 3. (2) an alteration is material for the purposes of these Regulations if the work, or any part of it, would at any stage result— (a) in a building or controlled service or fitting not complying with a relevant requirement where previously it did; or (b) in a building or controlled service or fitting which before the work commenced did not comply with a relevant requirement, being more unsatisfactory in relation to such a requirement. (3) In paragraph (2) “relevant requirement” means any of the following applicable requirements of Schedule 1, namely— Part A (structure) paragraph B1 (means of warning and escape) paragraph B3 (internal fire spread—structure) paragraph B4 (external fire spread) paragraph B5 (access and facilities for the fire service) Part M (access to and use of buildings). The above is the definition of material alteration I would suggest you study it. According to what you said it looks like your situation is not a material alteration but I am not a AI/BCO.

I can see your concerns but check out https://www.members.labc.co.uk/sites/default/files/EXT.SCA-Guidance-on-Smoke-Control-to-Common-Escape-Routes-Oct2015.LSt_.v2.151116.pdf and see it this guide helps.

I do not understand the layout, are you changing the front door of you flat or the staircase?

I think what you are proposing sounds reasonable but reducing 60 minute protection to 30 minute protection may need building regs approval you should consult with building control.
