In the office again.
I have been recently providing the electrical works for a local landlord; who has a street of 13 blocks of flats. All two storey, purpose built (1930s) 2 bed flats. Four flats per block (2 up, 2 down).

All privately rented; with no shared facilities.

Landlords current fire detection system (grade F) - ground floor & first floor communal hallway / stairway. (2 no. per block!!)

I`ve picked up on this, and he has asked me to (quote)"come up with something".

The entry doors to the flats are not fire rated OR self-closing. My local council has informed me that they do NOT class the properties as HMO`s.

Their unofficial guidance is this:

D/LD2 in communal area; plus 1 no. heat detector in the room which opens onto the communal area. PLUS

A seperate D/LD3 within the flats themselves.

However, he then went on to say that, in his opinion, there should be a panel near the entry/exit.

So, AFAIK, it`s now a grade C?

And, if you`re going to fit a panel, it`ll have to be 5 zones. So you wouldn`t bother with an individuated LD3 within each flat; they`d all be taken back to the panel.

I don`t think the landlord will go for a grade C; on the cost issue. Am I better off trying to get at least a D in there?

Any help you could provide would be greatly appreciated guys.

tell me Im wrong,

but without even going thru all the posts it seems to me if the flats are all co=joined then one addressable system would be your cheapest option,

simply nominate one singular communal ares to all flats,

job done.
