You need to reinstate the earth connection. Get another terminal block the same size and attach it to the metal tag while the fitting is off the ceiling. Then fit a short piece of 1mm2 earth wire cut from an offcut of T&E to the other terminal and connect that to the earth wire in the ceiling cable. Don't forget to sleeve the earth wire with G/Y sleeving.
Both toolstation and screwfix sell the splicelines in packs of either 10 or 100. Yeah may be bag size, although thats not very helpful to consumer lol.
