Definitely had a glass shade. What your looking for is a replacement with a neck so the lip sits on top of the screws. This site has a good selection but double check the diameter of the fitting: https://jmoncrieff.co.uk/John-Moncrieff-replacement-glass-light-shades/John-Moncrieff-clear-globe--with-neck-in-various--sizes- Ebay is a good source for replacement shades as well.

Still hard to get hold of this is it defo called a batten lamp holder abd where can i get it please lughtingspares dont do it thanks

There are so many flush celing lights available now, chose different styles for different rooms. A pendant over the dining table always works well no matter the ceiling height. You can hang it quite low. Spotlights on a dimmer switch work better in a lounge as you usually have table lamps and floorlamps. Change it up a bit. I don't think using flush ceiling lights in every room is a problem as long as they are not all the same style. Keep them similar but not the same fitting. Think of different materials too. Glass, wicker style shades or metal.
