Repayment mortgage. With repayment mortgages you pay the interest and part of the capital off every month. At the end of the term, typically 25 years, you should manage to have paid it all off and own your home.
Mortgages traditionally quote and charge interest on the basis of repayments in advance which means if you take out your mortgage on day 1 then the first repayment is also due on day 1 (the alternative would be repayments in arrears whereby the first repayment would be due after 1 month).
