Your rent is set by the terms of your lease, which is a contractual agreement between yourself and heylo when you purchased your share in your home. It is due each month on the share of your home that you do not own. 

As per the terms of your lease, your rent increases each year, normally in line with the RPI measure of inflation and we have sent you a letter with the details of the changes to your rent so that you can update any standing order details (if you pay by Direct Debit, then you donot need to make any changes, we will do this).
