I have just replaced a light pendant and noticed that when switch is off 28V present on rose between switched live and neutral. Checked other roses all the same. All connections in lighting circuit checked fine. Any ideas?

Capacitive and inductive linking can cause non energised circuits to show a voltage. This is why all unused cores in a cable should be earthed. Some low energy lamps have been known to flash when switched off because of this linking. Switching the old analogue meter to another range would show different reading on each range which showed the user this was the case.
Some switch mode supplied also have RF filters which can add to this.
Unless it makes the lights flash then normally one ignores these readings.
