Is it safe to put loft insulation down in the loft on top of ceiling spot lights.

NO just covering the lights without knowing what type they are is a BIG fire Hazard! Please do yourself a favour and take a look at the electrical safety council website and their downlighter safety leaflet. Unless the fittings are F fire rtaed and IC Insulation Covered rated then, covering them will cause the lamps to overheat and it may start a fire. If you ned to fully insulate the loft, it would be best to seek the help of a rgistered electricain and get them to quote to change the fittings for safe ones that are both fire rated and meet building regulation standards.

Dont cover them, it could cause a fire, get a spark to have a look, some have fire hoods fitted.

It is possible to buy protective bags to cover the spotlights, allowing heat to escape, but stopping them becoming obstructed by any insulation, it's usually advised to leave 150mm of space around the light, but this can vary depending on the make and type of light fitting.

Without knowing who did the electrical work or what type of spotlights have been installed then it is not recommended. You can purchase spotlight covers that you can place over the spotlights and then it would be safe to lay the insulation over.
