Check out Fire safety in purpose-built blocks of flats page 86.

BS 8214: 2016. Top,and sides should be 2 mm +/_ 1 mm (Maximum 4 mm minimum 2 mm) threshold gap is a little more complicated, check out the British Standard.

I think you are more likely to get a response from Firenet Forum http://firenetforum.org.uk/ they have a membership of many more FR assessors who would be able to give an informed reply.

Assuming the exit door doesn’t need to be fire resistant to a 30 minutes standard, also the exit width is satisfactory and it is installed according to BS 7273 part 4 then it should be acceptable, check it out with your fire risk assessor.

Was it working satisfactory when you took over the premises if it was then it is your responsibility and you need to replace it. You need to purchase a new mains operated one and have it fitted by an electrician, or get a battery operated one and fix it yourself. Check out https://www.safelincs.co.uk/co-detectors/ and https://www.legislation.gov.uk/ukdsi/2015/9780111133439/regulation/4

andre if it is three self contained flats then it is not an HMO check out HOUSING – FIRE SAFETY Guidance on fire safety provisions for certain types of existing housing and which designation does it fall under.

You need to speak to the charity.

Also you haven't give a description and type of premises involved.

An electrical plant room will have to be enclosed to a minimum 30 min standard and the door will have to be a fire door. As it will not be required for means of escape purposes but to prevent, fire and smoke spread, then the height, in my opinion would not be critical however you will need to contact the building control for their ruling.

Contact your local trading standards they are the enforcing authority on certain types of clothing they should be able to give you some authoritative advice. Check out https://www.gov.uk/find-local-trading-standards-office.

Its important if you get involved in a dispute.

As you would be fitting the call point upside down I would contact the manufacturer to check that it would work correctly in that position and as a result any wording on the face of the call point would also be upside down, therefore you then need to ask your self could this cause confusion for any person who had to use the call point. Have you considered modifying the dado rail to enable the test key to be used satisfactorily or relocating the call point a few cm higher.

If you source your materials in the UK then the supplier will be subject to the regulations if it is anywhere other than the UK they are not subject to the regulations consequently you need documented proof. Buying online you do not know where the supplier is located so you need a physical address to deal with and even in that case you cannot be sure they are only acting as agents, I think you should insist on copies of the certificates for your records.

It will be interesting to see their response.

I consider your comments acceptable except the one about "Pair of doors with primary leaf fitted with closer and secondary leaf bolted shut" and as it is illegal (article 14 RR(FS)O) it should be treated as a door without a lock, as it may appear you are condoning the situation. It should be reported to the enforcing authorities for them to consider what action to take. There is a video showing what happens when people escaping are confronted by a double door where one is locked showing the unsuccessful attempts to open the locked door.
