To light or not to light a communal entrance?

Hi, My Fire Risk Assessment and myself have a difference of opinion on whether emergency lighting is required in the communal area of a small block of flats. The block has 2 ground floor flats with separate entrances and 2 first floor flats who enter via a communal hallway.

The communal entrance door is glass and so are the side panels.

A straight flight of stairs goes to a landing near the top where there is a window. Two further steps forward reaches one flat and 4 steps on a return flight reaches the 2nd flat.

I believe LACORS 2008 is the definitive guidance and my interpretation is that conventional lighting is adequate for buildings of up to 2 storeys providing the escape route is not long. The layout is not complex, there is borrowed light and there are no vulnerable occupiers.

The Fire Risk Assessment says Emergency Lighting is required.

Who is right?

Thank you,

JB
