My two penn'orth ...
You can bet your bottom dollar that a five figure or higher sum in the spending column after about 2013 is a sure sign that the "building fund" that the bros and sisters were building up for the refurb of their own hall has been sent to London Bethel for the vanity project at Chelmsford.
Of course when that has been funded by the sale of the London properties (and then some) and the printing presses finally grind to a halt for the last time and even more deluded bethelites get booted to the kerb - well, then the whole lump sum which will surely be well into the millions will disappear in a puff of smoke to WAR-WICK.
