Be careful if you're only armed with a voltage detector. It would make sense to get the CU looked at. An electrician would probably remove the CU cover and tighten/check the connections, it's not unusual for a connection to be loose.
You need to work safely and diagnosis further than loose wires in the fuses is beyond the scope of a voltage detector.

Thanks, that's pretty much what I thought. I have got one of those pens which tell you when stuff is live so I can use that and be careful. It does use a DIN rail. Will have to be tomorrow morning now it's dark.
At the moment the RCD is tripping no matter which fuse is on. I've tried various individually and it trips almost straight away or straight away. But if I can swap the RCDs I'll know whether it's a faulty RCD or not as we never have problems with the other one which covers the back of the flat.
Sparky did check it and sign it off but that was a few years ago. We pretty much had the place rewired and the tripping issue didn't happen for along time, but has recently started happening more regularly, so something seems to have changed. Don't think I've got anything like that.
