It sounds like a loose neutral connection, or the bulb being used has been
busted during all the taking down and putting up again.

I know the bulb is fine, it was swithced between a screw for the old
fitting and a baynet for the temp one.

A neutral break will show as a live supply when you use a mains tester screw
driver, and to make sure that the circuit is actually continuous through all
conductors you need to use a multi-meter to test it. It's called a
continuity test.

Could you explain this one, would that mean that the Neutral side is live?
