I think you are only entitled to Rent Supplement under BTEA scheme if you were in receipt of it already immediately before you started the course. I also think you have to be renting outside of your parent's home for 6 months before you can be eligible for rent supplement. If this is the case, you won't qualify for the payment at all!
BTW, I wouldn't be too quick to re-arrange your living arrangements for the possibility of getting the grant in 2nd year (or maybe even this year). An Bord Snip Nua recommended that students will get the grant or BTEA but not both and of all the cuts on offer to the cash-strapped Minister for Education, this is a no-brainer. Students on BTEA are much better off than other welfare recipients such as people on FAS courses, especially if they are independent.
They would potentially get €204.30 per week if they had been on Jobseeker's benefit for example, the majority of their rent paid if on rent supplement, no registration fees of €1500 to pay, a one-off annual cost of education grant in September of €500, a maintenance grant of €6690 AND earn up to €3809 without affecting the other payments during the year. That's a potential to receive €17813.60 net in benefits/grants for a single person and to save €1500 on the reg fee and earn up to €3809 and get a lot of your rent paid also. I don't think there's much hope the govt can afford to keep this up!!!
Hope it doesn't seem that I'm having a go at you but it's best to take into account all the variables!
