Holiday pay when leaving

So im on a 10hr contract and I have put in my 2 weeks notice. Im just wondering if I will get paid for my remaining holiday. Because I heard from a few people that I will have to pay it back if I use to much before I leave. For reference I have used 3/4 of my holiday but we are only in the 4th month of the tax/holiday year. Will I have to pay some of this back?
