Isn't this also a situation for those back cover thingies - the type that
fill with foam and seal the spot light fitting to prevent fire bridging?

An Intumescent hood?

These are designed to maintain fire break integrity. They don't do
anything to allow the lamp fitting itself to cool however - you still
want some space round them

Not sure how possible these are to fit with no loft access mind!

Doable, they fold up to allow you to get them in there...
