I'm going to do cat amongst pigeons, do you really want that style lighting? It goes through plasterboard so it's reasonable to patch repair the holes , and replace with Idk what anything from an old fashioned single ceiling rose to the very fancy of whatever you can imagine
I know man. Lucky the place hasn’t been reduced to smoking hole in the ground really.
This is what I have now.
Thinking I just bite the bullet and get all new fittings for GU10 bulbs as per recommendations here.
