Well his 31k salary will net him 1923.13 per month then deduct any pension contributions.
Rent of 600 per month plus council tax, plus bills and transport and your up to 800/month in expenses before you've eaten.
Then 1100/month on loan repayments?
No idea what the sector pay is but without it he'd be on beans n toast for years and be unable to take those hosties out for even a shandy!!
