I am coming up to the last year in my IVA and it is written in about releasing funds from my mortgage if I can remortgage. What does this mean exactly ? What will I have to do ?

Hi. I have an IVA. I have had to take a loger in to help me pay bills. He has asked for Sky. Can I get sky ? Do they do credit checks ? IF so, can he get sky at my address in his name ? will he find out about my credit record ?
