What doors need to be fire doors in flats that are to be let out, do all
the doors need changing for fire doors?

The person to ask is your local Fire Prevention Officer,

.. Also I have been told they need to have fire door frames, is this a
different type of wood or something or is it just for the fitting for the
door closer?

The rebate against which the door closes needs to be of a minimum size,
which used to be at least 25mm deep and 25mm wide.
