Yes agree. Very little left in the pot.
Utilities alone, Gas, water,electric, phone (or mobile), TV licence, Insurances, council tax, service charges etc could be a large proportion.
Also one important figure - cost of food downroute!!
One other point, when I lived in Slough, not far from LHR, I could not get a bus that would ARRIVE early enough for my first report at 05.00. Agreed not a daily occurance but difficult to change report time.
