In essence no. My mortgage provider just needed to be told - they were happy I was keeping it with them, my mum's however did change the rate on her mortgage to that of a BTL. In our situation it was easier to rent the house out than sell. We are actually better off renting ours and renting somewhere else. I now have time to look around and think about buying another house tor eplace the one I'm renting to live in.
the Ins co's were OK too about changing the policy to a Landlords ins.
