10k a year works out at abour £833 a month before deductions, take off 6% for pension leaves £785 per month then take off tax, I reckon you'll be luck to see much over £700 net. (works out as £5.20 an hour for 40 hour week)
Now this is a decent enough amount of monet to live on a month for a single bloke. Assuming you can find somewhere to stay for £100 a week ( when i was at the college the average rent for a decent B&B was already reaching that and will probably be more than that now)
There is now no paid trips home, so if you have an applicant with a family then they will be going home every weekend - part of the responsibilty of being a parent. Depending on where you live that could be very expensive.
Also think about those who would want to apply as a change of career would probably be taking a pay cut. I assume this because 10,000 a year is less than i was earning in a call centre before I joined NATS 6 years ago.
