When you first joined us, your first monthly payment included a one-off lump sum. The rest of your premium was then spread over 11 monthly instalments - which were smaller due to that lump sum you paid at the start. 

This time around, you don’t pay that lump sum. Your annual premium is spread over 12 equal instalments. That means your monthly total might increase slightly on what it was last year, even though you’re paying less overall. 

So last year = Higher lump sum + 11 smaller monthly payments 

This year = No lump sum + 12 equal monthly payments
