No. You must answer truthfully[1] if the purchaser asks "is the next door
neighbour planning to build Heathrow Terminal Five in the adjoining
garden?".

That would only be an issue if you had an obligation to tell them[2]. Which
you (probably) don't. Unless they ask. After all, the neighbour's not doing
anything wrong is he.

[1] Truthfully does not exclude vaguely.



Solicitors always used to use answers like "the vendor is not aware of
any current planning applications but please rely on the usual
searches". I don't see why the same formula shouldn't be used now.
