Scottish Landranger sheet with most TPs -
OS64 (Glasgow) with 62 TPs (no space to list them all!)

NB - This information is taken directly from the OS Landranger 1:50000 maps, but may not be exact due to TPs steadily being removed.

Ed. - Whilst on the subject of 2m spot heights, there is another one - although no trig point - on Sheet 124 in Wales. Nothing unusual about this, except that its grid square, SH5839, is very odd indeed, also containing a railway line, a bit of the Afon Glarlyn, and virtually nothing else! A strong contender for the weirdest grid square in Britain. And thanks to Martin Prouse for drawing our attention to the fantastic trig point at TL617898 on OS143 - at a height of minus 1m!
