A company recently installed loft insulation but didn't put any above two ceilings which had low voltage spot lights installed in them.
When challenged, they claim that insulation must not be put above spotlights.
While I can see the logic of not putting any immediately above a 60W mains spotlight fitting, I'm not convinced that the entire bathroom ceiling should be uninsulated because of four 20W low voltage spots located towards the corners.
What would normal good practice be ?
I assume that the ceiling should be insulated, but maybe have a circular gap cut out around the fitting.
