Another option, is that the polarity is reversed.
Test a socket, see what readings you get.

True, and is the light switched on or off...is it a permanent live or switched? A few unknowns. Is there only one cable at the fitting? If so, odds are there's a nearby joint, of some kind.

A bit of late night viewing on loop impedance testing

Switched I have taken the fittings down and have cables In connectors the way they were connected in light so nothing has changed (connection wise)

Try and test near the consumer on the lighting circuit and see what voltage between the line and cpc

….is their a bunch of cables above the ceiling?...may be something amiss there. If it's a switch wire, that's the first thing to look at.

I will have a look tomorrow I have a feeling that could Be it.. it’s a single poll switch but whoever done it has blue in common brown in l1 earth in l2 so I’m thinking is the earth mixed in a junction box because it’s t&e at switch and pvc pvc singles in ceiling

Isolate first!!!!!!!!!! then you can check continuities.
Get some lever wagos for temp connections, then no mix ups.
