Thank you for your advice. I am pleased that this is your opinion also; this is the situation as I understood it but I needed some clarification. The neighbour in question has boasted of being a solicitor and last night was collecting evidence in the form of photographs with flash whilst I was out having a quiet smoke. I thought this was hilarious. If they did take me to court, it seems like I would win and the landlord or management of the flats would be responsible for the light. Would I be able to claim compensation for a day off taken to indulge their power and control fantasies also i.e to compensate me for my salary loss/day off equivalent?
