I'm your average DIYer and after advice about replacing a pendant light with a new flush metal fitting. I can fix the new light to the ceiling and the existing rose sits within the void of the new fitting without any clearance issues. Is it OK to leave it in place and wire the new fitting into the rose replacing the pendant's connections? I've had mixed replies from other forums. If I can't do this can I use wago connectors or choc blocs and leave them in the fitting or does it all have to go up into the loft space within a junction box? I'd much rather just connect to the rose and leave it in situ and I can still get a good fixing for the bracket. Thanks in advance.
