Insulation over electric wire

Yes, it's above a portico. Is it safe to lay insulation on top of it?
you can if the cable is in contact with the uninsulated ceiling on one side, so that any heat can escape downwards.
You can also have cable lying on top of insulation, so the heat can escape upwards.
But you must not have cable surrounded in insulation so there is no escape.
It would be best to put a non-flammable cover over the light fitting so that insulation and dust cannot fall on or into it. You can make a box out of plasterboard, or you can buy a smoke hood (that's not what it's intended for, but it will do the job and is cheap and easy), and there are enclosures sold for loft use, to keep insulation off downlighters.

What sort of bulb so you have in the fitting? LEDs and energy savers run cool, but halogens, especially, get very hot.

Not a problem with insulation over it.
However that looks rather like a choc-block wrapped in masking tape. Needs to be replaced with a proper junction box.
Inner coloured insulation of wires should not be visible and the CPCs need to be terminated properly.

There is no bulb. It's a sensor for lights located elsewhere.
So I took the tape of the choc block to replace it. It is rated as 15A. What junction box do i replace it with? i've got https://www.screwfix.com/p/debox-in...d=338580#product_additional_details_container and https://www.tlc-direct.co.uk/Products/ASJ804.html

Yes, it’s wrong, in several ways.
Copy the old wiring (you did take a photo or note how it was connected, didn’t you.?)
Also you need 4 terminals in that box, you only have 3. You should not use the earth terminal for anything other than earth!
