I assume that this light has been enjoyed through that window for more than 20 years and the right is not excluded in the deeds. The neighbour is absolutely correct that if you block this window, you would be obstructing his right to light and he could potentially bring an action against you. It does not matter that it’s an internal window all that matters is that it’s a window into a room. It could even be a garage. Whether blocking this window be actionable or not would depend on what other windows there are in the room and the amount of light which goes into that room from those other windows. Before any right to light obstruction action will succeed, the right to light must be reduced by a broad brush strokes 50% and that is a lot of light to have reduced. It is most unlikely that blocking this internal window will need to a reduction in light of 50%.
you might want to suggest that the neighbour takes legal advice although these few pages explain in relatively simple terms the situation.
it would be worthwhile thrusting them in front of him.
If you simply block the window, is then going to have to go to court which is not going to be cheap risk-free and he is likely to lose. If you have insurance on your property, check to see if there is legal expenses cover that would pay for the legal costs of the litigation as this is included with many contents and bricks and mortar policies.
What the neighbour appears to forget however is that the piano music or noise in general is nuisance. It may be that the piano is quite pleasant (if he is a reasonable player) but whether it’s pleasant or not is not relevant. You may not like piano music. You may not like the piano music which he plays.
You could get an injunction to make him stop the noise if it’s obtrusive during the day. However rather than spend or risk money on applying to court for an injunction, speak to the Environmental Health Department at the local authority who can issue a noise abatement notice if they are of the opinion that this noise from the piano is of such a level to constitute nuisance. For some reason, the neighbour seems to have forgotten that point.
Can I clarify anything for you?
