That's unusual, when you say neutral is it black/blue and connected to another black/blue via a connector block? Or is the black or blue wire connected to the switch?
If its connected to the switch then its actually a live wire (line) which the sparky that wired the lights needs a slap as it should have a red/brown bit of sleeve on it to say its no longer a neutral. It's very common as two core earth is normally used and not many sparks buy the twin red and earth.
