Low voltage between live and neutral

[Marks Electrics]

Hello, ive just been to look at a job with a light not working, after checking found voltage between live and neutral is 170v, between live and earth is 230v, is it just a case of a neutral issue, eg, loose connection, water ingress any suggestions would be great, cheers

First for me you need check voltage in DB where power go out from mcb to this lights ring and you know all ,so after check power in the ceiling roses and you can find problem.
