I have a leaky monoblock tap and will need to get it off to have a

You don't need to take it off. If it goes from on to off in a quarter turn
you may need to change the ceramic cartridges, or if it takes several turns
maybe the rubber washer. Both are accessable by removing the top, undoing
the screw & unscrewing the jumper - make sure the water is off first
obviously.

On inspection underneath, the big 'nut' looks extremely hard to
get at because of all the drainage and pipes etc.
Do plumbers use special bendy spanners and are all these nuts a
standard size?

Plumbers use a set of box spanners. They are around a £5 from a 'real'
plumbers shop.
