Hi Jane,

This depends on the area of the loft.

Putting noggins or doubling up will still spread weight onto the ceilings below, unless the 6 x 2's are new and at least 2" above the ceiling level.

We would always suggest that you use 8 x 2 joists (C16's) and if the span of the new joists is over 5750mm then the use of an RSJ will also be required.
