Fire doors on kitchen?

MUST be half hour fire doors to meet Building Standard 476 Part22 (where impractical: a heat rise detector MUST be installed)

But I also found this: Change to Building Regulations

As of 6th April 2007, it is no longer a building regulations requirement that a self closing device be fitted to internal fire doors in dwellings.

It has become the responsibility of the occupants to ensure that fire doors are closed at night. Closing devices are still required on flat entrance doors and garage doors leading into a dwelling. However, these closers now have to comply with BSEN 1154, which currently means they need to be overhead door closers.

So for doors to habitable rooms off a kitchen you shoudl have a fire door but it requires no special hinges? So the hall not being a habitable room (but has the stairs on it, doesn't have to be a fire door?)

My understanding is that a dwelling of no more than two stories, where the upper floor is less than 4.5m above ground level, which exits directly to street level, does not require internal fire doors unless there are "internal habitable rooms" (a room that does not open directly onto the hall).

The definition of a fire door usually includes suitable hinges and intumescent seals.

If there are three or more floors, then there needs to be a "protected route" - usually the hall and stairs, with every habitable room having a fire door (but as you say, a recent revision no longer requires that they are self-closing). Taller buildings require secondary escape routes as well.

Lot of additional regs about "fire compartments" on building converted to flats or multiple occupation.

The regs do get complicated when trying to cover unconventional internal layouts - for instance mine has an open plan living area with woodburning stove - so even the ground floor bedrooms require means of escape windows (but not fire doors).
