together this:

What would normal good practice be ?

Not neccesarily common but practice would be to install the insulation
to the whole ceiling, except for areas within about 100-200mm of the
spot lights. (Unless you're one of the rougher insulation companies,
who just throw the insulation over the top, I've seen it done!)
