Advice needed!!

I had to remove a wall light today as it was in the way of a new bookcase that we've bought. I'm looking for the best solution to make it safe - seems to be a mixed bag on google. Its connected into a chocky block connector (that was then fed into the light which I've removed). A lot of people are saying to wrap the chocky block in insulation tape and push it into the wall hole and then blanking plate over it (it is still visible at the top of the bookcase) - but others are saying this isn't safe and I should get a spark in to properly disconnect it. I don't want to waste money but I also don't want to scrimp and put ourselves at risk. Anyone got a better idea than me as to whether this is safe or not?

Cheers

A block behind a blank plate would be perfectly safe. Its not like you're hiding the cables in the wall and filling the old cables in the wall.

Do you have another wall light in the room? If you do the other end of that cable will be in the other wall light you could disconnect it out of that if you feel brave.

Looks like a stud wall if I were you I would just tape it up and push into the wall and filler the hole up. No danger at all there.
